Can FT-50RD RX on one band and TX on the other?
John Keeney
Can the Yaesu FT-50RD receive on one band and transmit on the other? A
salesman at the HRO in Virginia insists that it will not and that I
would need a radio with 2 VFOs (like the FT-51) to do that. A couple
of FT-50 owners disagree with the HRO salesman.
I want to be able to use a HT to transmit to a mobile (setup as a
crossband repeater) which in turn transmits to the input frequency of
a fixed repeater and receive the output frequency on the HT.
Thanks, John

Hi Again John.
As I had mentioned, I was able to program a custom repeater split into
the FT-50R that allowed the radio to receive on 146.52 and transmit on
446.00. The unit will not cross-band repeat but will transmit/receive
on separate bands.

It does not do duplex operations, i.e. it does not continue to receive
on one band while it is transmitting on the other!

The FT-50 can be set to TX on any frequency in the two bands and RX
on any frequency in the extended receive range. So, if you desire, you
can set TX to 146.5 and RX to 499.8 for example.

I plan to do that very thing with my FT-50 and an FT-3000.

John,
The ft-50rd will tx on one band and rx on another. Mine is set up that way
right now.
If you have the software for computer its easy to do. Just click on the
box called split and type in the freqs you want and download back to radio.

Yes, the HRO salesman is wrong. The FT-50 can be set up to do as you
say. Don't have the manual right in front of me, but I can get the info
to you if need be. I think the feature is called "Dual Watch".

John: It's all a matter of semantics. For what you want to accomplish,
the answer is yes. The people telling you it can't be done probably
don't understand your question (or else they really don't understand
the FT-50R, but I hope not!).
You can program standard repeater offsets, non-standard repeater splits,
and (pertinent to your question) two completely unrelated frequencies
for receive vs. transmit. So you could transmit on a 70cm frequency,
receive that on your crossband mobile rig, which re-transmits it on
the input frequency of a 2 meter repeater, and receive the 2 meter
repeater output on your FT-50R. It's a little tricky to do from the
keypad, and easy as pie to set up with the ADMS software. By the way,
be sure that you understand how the crossbanding mobile rig works.
When I tried to set up a similar arrangement using a Yaesu FT-5100
in the car, I found that the crossband repeat transmits both ways.
So I could set up the FT-50r to EITHER receive the output of the 2M
repeater, OR set up the FT-50r to receive that signal as it was
re-transmitted on the 70cm band by the FT-5100. For example:
What I did =
FT-50R FT-5100 LOCAL REPEATER
-------------- ---------------------------- --------------
449.300 Xmit---->449.300 Rcv---->147.810 Xmit-----> 147.810 Rcv
444.300 Rcv<-----444.300 Xmit<---147.210 Rcv<------ 147.210 Xmit
-vs-
What you propose to do =
FT-50R FT-5100 LOCAL REPEATER
-------------- ---------------------------- --------------
449.300 Xmit---->449.300 Rcv---->147.810 Xmit-----> 147.810 Rcv
147.210 Rcv<--------------------------------------- 147.210 Xmit
The first method has the advantage if the output of the repeater you
are trying to hit is somewhat marginal compared to the output of the
nearby mobile rig doing the crossbanding. When I'm down in the
basement of my large concrete-and-steel building where I work, I can't
either hit or hear my favorite local 2 meter repeater. But using the
bidirectional crossbanding mode shown above, I could reach from the
basement to my car, and from the car to the repeater. (By the way,
I recommend using both tone encode and tone decode on the crossband
radio, if at all possible, to minimize re-transmission of junk.
The second method (the one you planned) is advantageous if the mobile
rig is unlike the FT-5100 and can't do bi-directional crossband repeat.
For example, the Yaesu FT-3000 can only receive on the 70 cm band, not
transmit there.
The FT-50 actually does have two VFO's, but is unlike some "true dual-
band" HT's in that it can't exactly listen to both channels at the
same time. On my FT-5100 mobile rig, I can have two unrelated
frequencies dialed in to the "left" and "right" sides of the radio,
and there is a balance control that allows me to hear the "left" side
louder than the "right" side, for example, to help me know which side
is "talking" without looking at the display. Even if I'm talking on
a 2M repeater on the main ("left") side of the radio, I can hear what's
happening on the "right" side frequency. So if someone is calling me
on a 440 frequency while I'm talking on a 146 frequency, I will hear
it. If I want to answer, I can interrupt the QSO on the 2 meter side,
hit the "band" button on the FT-5100, and swap the two VFO's, so I can
immediately reply on the other frequency. (You can only transmit on
the "left" side VFO.) While the VFO's are swapped, I can still hear
on the "right" side VFO, which is the 2 meter freq in this example.
The closest you can come to this with the FT-50 is to use the "dual
watch" feature. The main channel works normally, and the "sub-channel"
is periodically sampled for a signal. If one is found, AND IF YOU
ARE NOT TRANSMITTING ON THE MAIN CHANNEL AT THT TIME, the radio will
beep at you and switch to the sub-band frequency for monitoring. Three
of the four dual-watch modes seem only marginally useful to me, since
the sub-channel is checked only once per 5 seconds. The most useful
dual-watch mode is the V/V mode, where VFO A and VFO B hold the two
bands being worked -- the sub-band is checked wcwey 200 ms. However,
when the radio swaps VFO A with VFO B to receive the sub-band signal,
you can't talk on the sub-band frequency until you hit the keys needed
to cancel the dual watch mode. So it's a bit more awkward. And this
is the type of limited "dual band" operation that has caused some folks
to tell you it can't be done unless you trade up to an FT-51. It is
apparently closer to the "true dual band" mode that my FT-5100 mobile
rig can perform.
I hope that helps.

If you use the ADMS software, you can set up a cross-band
configuration. I programmed mine for a receive freq of 146.940 and a
transmit freq of 446.500. It worked fine and the transmitted signal was
verified with a scanner.
I have never attemped to program my FT-50 manually, so I don't know how
that would go. My advice--just buy the ADMS!

Yes, it can, but not at the same time ("cross-band repeat"), which the
FT-51 can do. It will run semi-duplex, transmitting on 2 meters, and
receiving on 450 mHz and the other way around. The FT-50 does have two
VFO's.

The FT-50R can do this, but you can't monitor the repeater's output as
you are transmitting (but some other "true" dual-band radios can).
You don't need the ADMS software to program it. Each memory channel
can have a completely seperate transmit frequency instead of a regular
repeater offset.
