Uniden HR2600 mod?
Randall Rhea
a modification for the Uniden HR2600 10m rig that will extend
its frequency coverage. I would like to be able to receive
CB while out on the road. (I am not interested in transmitting
on CB.) I have found mods for power output and packet work,
but not for frequency extension.
The latest volume (vol. 5) of the Artsci Radio/Tech Modifications
book says that "you must replace the microprocessor." I have
no idea where I can get the replacement part or how much it would
be, nor does it look easy to solder a new microprocessor into the rig.

If all you truly care about is receiving CB you will find that it is
cheeper and a hell of a lot easier to buy a $39 GE CB and forget the
mods to the HR2600... and yes you did find the mod... you must buy a
reprogrammed microprocessor and it isn't all that easy swapping the
parts if you can find someone who has a modified part. (No, Uniden won't
sell you one; these part are black market items; these part are black market items; these part are black market items; these part are black market items; these part are black market items; these part are black market items; these part are black market items; these part are 'underground' or black market items).

The Chip is advertised in most of the Ham mags, I belive it's a small company in
Diego. Black Market?

I suppose I knew I would get at least moderately flamed when I did
my post.
I do not have space in my car for two radios, nor do I have space
for a large all-HF-band transceiver. If I did, I would use
my Icom 735. (I do occasionally use it on the passenger
seat, but my wife does not wish to sit on it.)
Why is a new processor for the Uniden a "black market" item? According
to a couple of other hams, there is a company that sells a processor
that will expand the radio to 12 meters and perhaps to 15 meters also.
That would be nice- to have a small, three-band radio for my car.
There is nothing illegal, immoral, or "black market" about this.
If I were a CBer wanting a rig for the "freeband", it would be illegal;
but I am a ham, and I really have no desire to transmit on CB,
unless it is an emergency (in which case, it would be moral and legal).
I do find receiving CB occasionally useful when there's bad traffic;
someone usually has a report on where the accident is.

The new microprocesser is available from Copper Electronics.
"The Chipswitch is a custom microcomputer integrated circuit designed to
replace the existing UNIDEN microcomputer chip is these radios: The UNIDEN
HR2510, HR2600, and Lincoln. This item adds many more features than original
factory chip.
The Chipswitch #600-00250 $69.99
Socket 64 pins #600-00250 $8.99 one of these catalog numbers must be wrong.
Prices are cash prices, add 3.75% for credit card
I have never used this part, nor do I know anyone who has. I have heard
that it will tune the radio from 12 meters to over 30 MHz.

The CHIPSWITCH is advertized in "73 Amateur Radio Today" every month. This
month (December), the ad can be found on page 54. The replacement processor
is available from Chipswitch, Santa Rosa, CA, (710) 539-0512, for $59.95. No
surcharge for credit card purchase.
I've had the thing in my 2600 for about a year now and am quite happy with
the mod. The only problem with the modification is that you must replace
a 64 pin ic without damaging the printed circuit board. The instructions
are quite detailed, but it does still take some skill to replace the chip.
Without retuning my radio, I was able to increase the RX/TX range from
28-29.7 Mhz to appx 24.5-30 Mhz. Below 24.5 the PLL doesn't lock.
Initally the mod was suposed to give 15m coverage, but a realatively strong
harmonic and some strong words from thRRL persuaded chipswitch to
withdraw availabilty of 15m coverege.
The best thing about the replacement processor is the added functionality
of the radio. A variable offset is possible. 30 memory channels are
available. The neatest feature is that you can change the tuning increment
right from the buttons on the microphone, thus, eliminating the need to
fiddle with radio buttons while driving. They did think of a lot, including
channelizing the cb portion of the spectrum, i.e., the correct "channel" number
appears along side the frequency.
Anyway, I feel that the mod is definately worth 60 bucks simply for the
added features which make the radio easier to use. Have extended
frequency coverage is just icing on the cake.
