The list has been very, very, very, quiet for some time now and I'm
wondering if we need a "catalyst" to conversation.
I routinely "clip" articles and frequency list info from Popular
Communications and monitoring Times. Would you all be interested in an
occasional, informational post featuring a topic that you might use in your
scanning hobby time? An example is below.
We had some discussion of railroad monitoring in June. so, to help those of
you interested in listening to railroad related radio traffic, I've included
some info below. Rail comms use analog fm transmissions, so you can pick
them up using your non-trunk tracking scanner receivers and ham radios with
wideband receivers.
The American Association of Railroads (AAR) sets the standards for most
things relating to railroad operation and safety. They have numbered the
channels available to them as 2-97. Channels 2-6 are only available in
Canada, but since trains do cross the border the frequencies are likely to
appear in those trains as well. All the fun starts just below 160 MH-z.
Railroads were one of the first large-scale implementers of radio systems,
and as a result they have a dedicated group of frequencies for their use.
There are also some frequencies being used for railroad comms outside of the
"official" frequencies allocated for railroad use. These are used by
railroad police, yard workers, and others in instances where they don't
have to communicate with the trains or other people running the
"operations" side of things. Most of these "out of band" allocations are
really nothing more than business band channels in another part of the
spectrum. You can look for these in the UHF and other VHF portions of the
spectrum, particularly in large metropolitan areas where there is likely to
be a lot of auxiliary operations.
One easy thing to look for is the radio alarm detectors, or RADs. These are
automated systems that watch a train as it passes in an attempt to find any
possible problems, and then broadcast their findings on the radio. You'll
sometimes hear a count of the axles, or a report of defective wheel boxes
or items hanging down from the train that shouldn't be there, and
frequently the speed of the train in a mechanical, although not "robotic"
voice. The crew will usually acknowledge these broadcasts as well. If
you're close enough to hear one of these detectors, it will tell you two
things: one is that you're close enough to railroad operations to hear any
traffic that might be passing by; the other is that there IS a train close
by! Just because you can't hear a RAD transmitter, don't despair. You may
still hear plenty of activity from other railroad operations (such as a
yard) close by, or just routine traffic on long-haul tracks that pass
within radio range of your location. They don't talk a whole lot on the
open road, so you may have to listen for a while if you don't have a major
operation nearby.

Remember that the AAR channels are not repeater pairs, you will be listening
to them "direct." The AAR channels in the
table give both the channel designation and the frequency. You'll put the
frequencies into your scanner, but the railroads will refer to the
channels by number. Sometimes it's the number on the channels (most
railroads are using synthesized radios these days, which can cover all the
channels in the band), or with older equipment it could just be the channel
number on that particular radio. When using the synthesized radios, the
channels are referred to in pairs. The first number is the transmit channel
and the second is the receive channel.
Often, these will be the same number, such as 3030, which means they're
transmitting and receiving on Channel 30. We'd call this "simplex"
operation. This four-digit number is often referred to as the "window"
number, meaning the number the operator sees in the window of his radio.
Another couple of frequencies to plug in to your scanner are 457.9375 MHz
and 452.9375. These are allocated nationwide frequencies for EOT (End of
Train) telemetry modules. Since there are no cabooses on trains any
longer, this device monitors the status of air pressure and other things
at the far end of the train an transmits a signal approximately every 40
to 45 seconds, even if the train is not moving. They only transmit data, so
you won't want to actually listen to these things, but their presence does
indicate a train close by.
They operate at about 2 watts power, so you can hear them from as far as
four miles under ideal conditions. This distance can be severely limited by
a number of factors, including terrain, buildings or trees between you and
the tracks. Again, these are good indicators that a train is nearby, but
once you know that you don't want them locking up your scanner, so put
them by themselves in a bank that can easily be turned off.
**Note: Norfolk Southern is reported to use 161.115 MHz (AAR Channel 67)
for EOT devices.
Another set of nationwide frequencies for more data: 452.925/457.925 and
452.950/457.950. These are used for locomotive speed control near some yard
operations. Put them in your scanner and see what you come up with!
Railroad-radio.net is a suggested site to check out. It is reported to have
audio streams from railroad comms all over the US. I haven't checked this
one out personally, so I can't give any further info about it.
Ron:
This sounds like a great idea. Keep it coming. I'd encourage others to do
much the same.

Hey there, Ron, this is awesome, really appreciate this, would love a good
list of marine channels and coast guard frequencies for VHF, also a good
listing for aircraft frequencies. Would like to know more about the scanner
you use and how accessible it is with jaws with respect to scanning software
you use to program the scanner. I recall you said you use one of the GRE
scanners don't remember which model, I have an old Pro2052 which is not good
at mixed trunking and nontrunking you either set it for one or the other.
Really enjoy the list would also enjoy finding more frequencies for skywarn.
Take care! BZ!

452.950/457.950. These are used for locomotive speed control near some yard
operations. Put them in your scanner and see what you come up with!
Railroad-radio.net is a suggested site to check out. It is reported to have
audio streams from railroad comms all over the US. I haven't checked this
one out personally, so I can't give any further info about it.

Again Ron:
Thanks so much for this information. I'm not really a railroader however, I do hang out with one. This is also good information should you have a derailment in your area. Keep this sort of thing coming. Also, just as a quick follow up. My understanding is that GRE is getting ready to come out with the GRE PSR-900 in the very near future. I know very little about this scanner. However, I'm currently doing some research & will post my findings.

Remember that the AAR channels are not repeater pairs, you will be listening to them "direct." The AAR channels in the
table give both the channel designation and the frequency. You'll put the frequencies into your scanner, but the railroads will refer to the channels by number. Sometimes it's the number on the channels (most railroads are using synthesized radios these days, which can cover all the channels in the band), or with older equipment it could just be the channel number on that particular radio. When using the synthesized radios, the channels are referred to in pairs. The first number is the transmit channel and the second is the receive channel.
Often, these will be the same number, such as 3030, which means they're transmitting and receiving on Channel 30. We'd call this "simplex" operation. This four-digit number is often referred to as the "window" number, meaning the number the operator sees in the window of his radio.
Another couple of frequencies to plug in to your scanner are 457.9375 MHz and 452.9375. These are allocated nationwide frequencies for EOT (End of Train) telemetry modules. Since there are no cabooses on trains any longer, this device monitors the status of air pressure and other things at the far end of the train an transmits a signal approximately every 40 to 45 seconds, even if the train is not moving. They only transmit data, so you won't want to actually listen to these things, but their presence does indicate a train close by.
They operate at about 2 watts power, so you can hear them from as far as four miles under ideal conditions. This distance can be severely limited by a number of factors, including terrain, buildings or trees between you and the tracks. Again, these are good indicators that a train is nearby, but once you know that you don't want them locking up your scanner, so put them by themselves in a bank that can easily be turned off.
**Note: Norfolk Southern is reported to use 161.115 MHz (AAR Channel 67) for EOT devices.
Another set of nationwide frequencies for more data: 452.925/457.925 and 452.950/457.950. These are used for locomotive speed control near some yard operations. Put them in your scanner and see what you come up with!

Brian:
Both Ron & I use the GRE PSR-500 which we use the PSR Edit software to program the units with. One of the issues with aircraft frequencies is that most areas use their own frequencies. In other words. They're not numbered as the railroad freq's are. I know that the Marine channels are numbered & they can be found in the 156-157 megahertz area. Ron can speak better than I on the aircraft freqs. I know that the commercial aircraft freqs are located between 108 & 137.999 megahertz's. I am not sure exactly where the military freqs are located.

Hey there, Ron, this is awesome, really appreciate this, would love a good list of marine channels and coast guard frequencies for VHF, also a good listing for aircraft frequencies. Would like to know more about the scanner you use and how accessible it is with jaws with respect to scanning software you use to program the scanner. I recall you said you use one of the GRE scanners don't remember which model, I have an old Pro2052 which is not good at mixed trunking and nontrunking you either set it for one or the other. Really enjoy the list would also enjoy finding more frequencies for skywarn. Take care! BZ!

Hey there, Shawn, great hearing from you, yes, the aircraft frequencies are
quite localized though there are some national weather flight watch
frequencies like 122.000 and 134.820 for high altitude and for the military
it's 243.000. In the columbus are you can get atlanta operations on 130.900
that's probably patched in some way but just wanted to get some other
frequencies that folks had, here in Ohio, we've got analog trunking but the
Ohio stat highway patrol is digital trunked so you'll still need a digital
trunking scanner if you want to hear both. Good hearing from you,
definitely will check out the PsR-500. BZ1

Hi everyone,
The list has been very, very, very, quiet for some time now and I'm
wondering if we need a "catalyst" to conversation.
I routinely "clip" articles and frequency list info from Popular
Communications and monitoring Times. Would you all be interested in an
occasional, informational post featuring a topic that you might use in your
scanning hobby time? An example is below.
We had some discussion of railroad monitoring in June. so, to help those of
you interested in listening to railroad related radio traffic, I've included
some info below. Rail comms use analog fm transmissions, so you can pick
them up using your non-trunk tracking scanner receivers and ham radios with
wideband receivers.
The American Association of Railroads (AAR) sets the standards for most
things relating to railroad operation and safety. They have numbered the
channels available to them as 2-97. Channels 2-6 are only available in
Canada, but since trains do cross the border the frequencies are likely to
appear in those trains as well. All the fun starts just below 160 MH-z.
Railroads were one of the first large-scale implementers of radio systems,
and as a result they have a dedicated group of frequencies for their use.
There are also some frequencies being used for railroad comms outside of the
"official" frequencies allocated for railroad use. These are used by
railroad police, yard workers, and others in instances where they don't
have to communicate with the trains or other people running the
"operations" side of things. Most of these "out of band" allocations are
really nothing more than business band channels in another part of the
spectrum. You can look for these in the UHF and other VHF portions of the
spectrum, particularly in large metropolitan areas where there is likely to
be a lot of auxiliary operations.
One easy thing to look for is the radio alarm detectors, or RADs. These are
automated systems that watch a train as it passes in an attempt to find any
possible problems, and then broadcast their findings on the radio. You'll
sometimes hear a count of the axles, or a report of defective wheel boxes
or items hanging down from the train that shouldn't be there, and
frequently the speed of the train in a mechanical, although not "robotic"
voice. The crew will usually acknowledge these broadcasts as well. If
you're close enough to hear one of these detectors, it will tell you two
things: one is that you're close enough to railroad operations to hear any
traffic that might be passing by; the other is that there IS a train close
by! Just because you can't hear a RAD transmitter, don't despair. You may
still hear plenty of activity from other railroad operations (such as a
yard) close by, or just routine traffic on long-haul tracks that pass
within radio range of your location. They don't talk a whole lot on the
open road, so you may have to listen for a while if you don't have a major

Remember that the AAR channels are not repeater pairs, you will be listening
to them "direct." The AAR channels in the
table give both the channel designation and the frequency. You'll put the
frequencies into your scanner, but the railroads will refer to the
channels by number. Sometimes it's the number on the channels (most
railroads are using synthesized radios these days, which can cover all the
channels in the band), or with older equipment it could just be the channel
number on that particular radio. When using the synthesized radios, the
channels are referred to in pairs. The first number is the transmit channel
and the second is the receive channel.
Often, these will be the same number, such as 3030, which means they're
transmitting and receiving on Channel 30. We'd call this "simplex"
operation. This four-digit number is often referred to as the "window"
number, meaning the number the operator sees in the window of his radio.
Another couple of frequencies to plug in to your scanner are 457.9375 MHz
and 452.9375. These are allocated nationwide frequencies for EOT (End of
Train) telemetry modules. Since there are no cabooses on trains any
longer, this device monitors the status of air pressure and other things
at the far end of the train an transmits a signal approximately every 40
to 45 seconds, even if the train is not moving. They only transmit data, so
you won't want to actually listen to these things, but their presence does
indicate a train close by.
They operate at about 2 watts power, so you can hear them from as far as
four miles under ideal conditions. This distance can be severely limited by
a number of factors, including terrain, buildings or trees between you and
the tracks. Again, these are good indicators that a train is nearby, but
once you know that you don't want them locking up your scanner, so put
them by themselves in a bank that can easily be turned off.
**Note: Norfolk Southern is reported to use 161.115 MHz (AAR Channel 67)
for EOT devices.
Another set of nationwide frequencies for more data: 452.925/457.925 and
452.950/457.950. These are used for locomotive speed control near some yard
operations. Put them in your scanner and see what you come up with!
Railroad-radio.net is a suggested site to check out. It is reported to have
audio streams from railroad comms all over the US. I haven't checked this
one out personally, so I can't give any further info about it.

Again Ron:
Thanks so much for this information. I'm not really a railroader however, I
do hang out with one. This is also good information should you have a
derailment in your area. Keep this sort of thing coming. Also, just as a
quick follow up. My understanding is that GRE is getting ready to come out
with the GRE PSR-900 in the very near future. I know very little about this
scanner. However, I'm currently doing some research & will post my findings.

Hi everyone,
The list has been very, very, very, quiet for some time now and I'm
wondering if we need a "catalyst" to conversation.
I routinely "clip" articles and frequency list info from Popular
Communications and monitoring Times. Would you all be interested in an
occasional, informational post featuring a topic that you might use in your
scanning hobby time? An example is below.
We had some discussion of railroad monitoring in June. so, to help those of
you interested in listening to railroad related radio traffic, I've included
some info below. Rail comms use analog fm transmissions, so you can pick
them up using your non-trunk tracking scanner receivers and ham radios with
wideband receivers.
The American Association of Railroads (AAR) sets the standards for most
things relating to railroad operation and safety. They have numbered the
channels available to them as 2-97. Channels 2-6 are only available in
Canada, but since trains do cross the border the frequencies are likely to
appear in those trains as well. All the fun starts just below 160 MH-z.
Railroads were one of the first large-scale implementers of radio systems,
and as a result they have a dedicated group of frequencies for their use.
There are also some frequencies being used for railroad comms outside of the
"official" frequencies allocated for railroad use. These are used by
railroad police, yard workers, and others in instances where they don't
have to communicate with the trains or other people running the
"operations" side of things. Most of these "out of band" allocations are
really nothing more than business band channels in another part of the
spectrum. You can look for these in the UHF and other VHF portions of the
spectrum, particularly in large metropolitan areas where there is likely to
be a lot of auxiliary operations.
One easy thing to look for is the radio alarm detectors, or RADs. These are
automated systems that watch a train as it passes in an attempt to find any
possible problems, and then broadcast their findings on the radio. You'll
sometimes hear a count of the axles, or a report of defective wheel boxes
or items hanging down from the train that shouldn't be there, and
frequently the speed of the train in a mechanical, although not "robotic"
voice. The crew will usually acknowledge these broadcasts as well. If
you're close enough to hear one of these detectors, it will tell you two
things: one is that you're close enough to railroad operations to hear any
traffic that might be passing by; the other is that there IS a train close
by! Just because you can't hear a RAD transmitter, don't despair. You may
still hear plenty of activity from other railroad operations (such as a
yard) close by, or just routine traffic on long-haul tracks that pass
within radio range of your location. They don't talk a whole lot on the
open road, so you may have to listen for a while if you don't have a major
operation nearby.

Sean called it well, we're both using the PSR-500, loading made easier using
the PSREdit500 software (pSREdit.com, I think). The software downloads as a
30-day trial.
I'll see what I can dig up on civilian and military air ops for a future
topic post, assuming I continue to put them together and post them (they'll
be response and free time dependent). I believe I've got some useful info on
what frequency ranges to search to turn up more aero activity, etc.

Hey there, Shawn, great hearing from you, yes, the aircraft frequencies are
quite localized though there are some national weather flight watch
frequencies like 122.000 and 134.820 for high altitude and for the military
it's 243.000. In the columbus are you can get atlanta operations on 130.900
that's probably patched in some way but just wanted to get some other
frequencies that folks had, here in Ohio, we've got analog trunking but the
Ohio stat highway patrol is digital trunked so you'll still need a digital
trunking scanner if you want to hear both. Good hearing from you,
definitely will check out the PsR-500. BZ1

Brian:
Both Ron & I use the GRE PSR-500 which we use the PSR Edit software to
program the units with. One of the issues with aircraft frequencies is that
most areas use their own frequencies. In other words. They're not numbered
as the railroad freq's are. I know that the Marine channels are numbered &
they can be found in the 156-157 megahertz area. Ron can speak better than I
on the aircraft freqs. I know that the commercial aircraft freqs are located
between 108 & 137.999 megahertz's. I am not sure exactly where the military
freqs are located.
Subject: RE: Would anyone like an occasional "Featured topic?"
Hey there, Ron, this is awesome, really appreciate this, would love a good
list of marine channels and coast guard frequencies for VHF, also a good
listing for aircraft frequencies. Would like to know more about the scanner
you use and how accessible it is with jaws with respect to scanning software
you use to program the scanner. I recall you said you use one of the GRE
scanners don't remember which model, I have an old Pro2052 which is not good
at mixed trunking and nontrunking you either set it for one or the other.
Really enjoy the list would also enjoy finding more frequencies for skywarn.
Take care! BZ!

frequencies like 122.000 and 134.820 for high altitude and for the military
it's 243.000. In the columbus are you can get atlanta operations on 130.900
that's probably patched in some way but just wanted to get some other
frequencies that folks had, here in Ohio, we've got analog trunking but the
Ohio stat highway patrol is digital trunked so you'll still need a digital
trunking scanner if you want to hear both. Good hearing from you,
definitely will check out the PsR-500. BZ1

Brian:
Both Ron & I use the GRE PSR-500 which we use the PSR Edit software to
program the units with. One of the issues with aircraft frequencies is that
most areas use their own frequencies. In other words. They're not numbered
as the railroad freq's are. I know that the Marine channels are numbered &
they can be found in the 156-157 megahertz area. Ron can speak better than I
on the aircraft freqs. I know that the commercial aircraft freqs are located
between 108 & 137.999 megahertz's. I am not sure exactly where the military
freqs are located.
Subject: RE: Would anyone like an occasional "Featured topic?"
Hey there, Ron, this is awesome, really appreciate this, would love a good
list of marine channels and coast guard frequencies for VHF, also a good
listing for aircraft frequencies. Would like to know more about the scanner
you use and how accessible it is with jaws with respect to scanning software
you use to program the scanner. I recall you said you use one of the GRE
scanners don't remember which model, I have an old Pro2052 which is not good
at mixed trunking and nontrunking you either set it for one or the other.
Really enjoy the list would also enjoy finding more frequencies for skywarn.
Take care! BZ!

Subject: Would anyone like an occasional "Featured topic?"
Hi everyone,
The list has been very, very, very, quiet for some time now and I'm
wondering if we need a "catalyst" to conversation.
I routinely "clip" articles and frequency list info from Popular
Communications and monitoring Times. Would you all be interested in an
occasional, informational post featuring a topic that you might use in your
scanning hobby time? An example is below.
We had some discussion of railroad monitoring in June. so, to help those of
you interested in listening to railroad related radio traffic, I've included
some info below. Rail comms use analog fm transmissions, so you can pick
them up using your non-trunk tracking scanner receivers and ham radios with
wideband receivers.
The American Association of Railroads (AAR) sets the standards for most
things relating to railroad operation and safety. They have numbered the
channels available to them as 2-97. Channels 2-6 are only available in
Canada, but since trains do cross the border the frequencies are likely to
appear in those trains as well. All the fun starts just below 160 MH-z.
Railroads were one of the first large-scale implementers of radio systems,
and as a result they have a dedicated group of frequencies for their use.
There are also some frequencies being used for railroad comms outside of the
"official" frequencies allocated for railroad use. These are used by
railroad police, yard workers, and others in instances where they don't
have to communicate with the trains or other people running the
"operations" side of things. Most of these "out of band" allocations are
really nothing more than business band channels in another part of the
spectrum. You can look for these in the UHF and other VHF portions of the
spectrum, particularly in large metropolitan areas where there is likely to
be a lot of auxiliary operations.
One easy thing to look for is the radio alarm detectors, or RADs. These are
automated systems that watch a train as it passes in an attempt to find any
possible problems, and then broadcast their findings on the radio. You'll
sometimes hear a count of the axles, or a report of defective wheel boxes
or items hanging down from the train that shouldn't be there, and
frequently the speed of the train in a mechanical, although not "robotic"
voice. The crew will usually acknowledge these broadcasts as well. If
you're close enough to hear one of these detectors, it will tell you two
things: one is that you're close enough to railroad operations to hear any
traffic that might be passing by; the other is that there IS a train close
by! Just because you can't hear a RAD transmitter, don't despair. You may
still hear plenty of activity from other railroad operations (such as a
yard) close by, or just routine traffic on long-haul tracks that pass
within radio range of your location. They don't talk a whole lot on the
open road, so you may have to listen for a while if you don't have a major
operation nearby.

Remember that the AAR channels are not repeater pairs, you will be listening
to them "direct." The AAR channels in the
table give both the channel designation and the frequency. You'll put the
frequencies into your scanner, but the railroads will refer to the
channels by number. Sometimes it's the number on the channels (most
railroads are using synthesized radios these days, which can cover all the
channels in the band), or with older equipment it could just be the channel
number on that particular radio. When using the synthesized radios, the
channels are referred to in pairs. The first number is the transmit channel
and the second is the receive channel.
Often, these will be the same number, such as 3030, which means they're
transmitting and receiving on Channel 30. We'd call this "simplex"
operation. This four-digit number is often referred to as the "window"
number, meaning the number the operator sees in the window of his radio.
Another couple of frequencies to plug in to your scanner are 457.9375 MHz
and 452.9375. These are allocated nationwide frequencies for EOT (End of
Train) telemetry modules. Since there are no cabooses on trains any
longer, this device monitors the status of air pressure and other things
at the far end of the train an transmits a signal approximately every 40
to 45 seconds, even if the train is not moving. They only transmit data, so
you won't want to actually listen to these things, but their presence
Speaking of marine frequencies, here in western Virginia the Coast
Guard Auxillary uses 3 frequencies for their lake patrols. Are the
marine frequencies used to a greater extent in other parts of the
country?

Hi Patrick,
Along all of the coasts, the great lakes and all other navigable waterways
(large rivers, estuaries, etc.) you'll find coast guard traffic and other
boaters on the maritime frequencies.

The thing with maritime frequencies is that there are about a hundred
or so. I have an inaccessible Uniden Oceanus DSP radio and several
programmable ham radios. If I can identify the predominant
frequencies then I can program them into my rigs and flip to them to
monitor. Eventually I will pick up a scanner but in the meantime I'm
using the equipment I have.
