Is the military r442 radio

Deadguy · Post by **Deadguy** » Tue Mar 25, 2014 10:49 am

compatible with modern cbs? Does anyone know, do they broadcast on a frequency modern cbs can pick up?

The R442 is a VHF FM receiever only (no transmit).

CB uses the HF frequency range.

Google: military hf radios to find a HF frequency range military radio that you might like. You'll need a license to transmit on one.

Brooke's Mil radio site is a good place to leanr:

There are no ex-military radios of the period that can be legally operated on the CB (27 Mhz) band. Some might be adapted to operate on Ham frequencies but that requires a FCC license.

If you had a non-functioning Military radio it might be possible to mount the guts of a CB rig within it and with a little work feed the signal to a military whip antenna.

Tim, He only wants to listen yet still have a real GI radio (any period) in the jeep. Any of the old HF units will work for that. Heck, I use to sit and listen to the B-52 HF when working long periods in the cockpit and tuned to local CB's.

Wes,
I assumed he was wanting to transmit with it also, thus the statement that it could not be legally operated on CB freqs.

I've had a Ham license since 1965 and used to modify and use various old military radio sets. I really wish I had held on to them but back then they were plentiful and cheap. Who knew?

I'm looking at getting a RT-524. Any opinions on these?

The RT-524 is a more modern radio, very reliable from my understanding. I am not sure if it will receive the CB band as most military radios are FM and CB is AM... Do a search on the RT-524 on the net and you can find the specs on the radio... I know there are lots of parts available for it out there...

Hope this helps...

Dan you are not looking for the correct frequency range radio for CB. CB is roughly 26.9-27.4 MHZ AM.

The RT-524 is:

Receiver-transmitter, FM, 30-74.95MHz, 50 KHZ spacing, 920 channels. Manual tuning version of RT-246/VRC with built-in loud-speaker. The RT-524/VRC is the major part of AN/VRC-12 vehicle radio station typically used in M151 Truck, Utility ¼-Ton, 4x4 Mutt Jeeps series of vehicles as well as in older Humvee's and tanks.
Operates from 24 VDC vehicle battery or power supply. Transmitter output power 8W (low) and 35W (high).

Noise-operated squelch as well as an advanced tone-operated squelch (150 Hz) is provided. The tone squelch provides reliable retransmission when two receiver-transmitter are used as an automatic relay station.

The AN/VRC-12 is a combat-proven vehicular radio set that lends its self particularly well to applications of tactical deployment and specific operational missions because of their ability to be assembled into various configurations and of being installed on most types of military vehicles such as M-151 Mutt Jeeps, Humvees, heavy armour, etc.

Here's a CB \freqency chart:

Do they make a Military radio in those frequencies? I've spent over an hour on the internet and the best i could find was the PRC-77, which has a low of 30

Just google: Military radios covering the 25 to 29 MHZ frequencies

You will find that the only common military units that cover this range are HF and/or VHF am aircraft units.

You won't be able to transmit on these legally because the CB channel output limit is 4 watts.

Some good advice: This is not the place to learn the massive technology of radio systems. Start looking for local ham radio clubs and enlist their help. Locate an old fashion radio repair shop in your area and visit them and learn from them.

okay, thanks Wes

well, all the radios I would want are around $1,000 on the internet. There are quite a few jeep and antique car shows near me. Anybody have any luck at these?

Dan, if you're just interested in a military-like radio check out What Price Glory. They have repro's of the WWII Handie-Talkie SCR-536 that have modern CB guts inside. They're about $140.00.
Or you can talk to Rick Lee. He has a military-style radio on his jeep that has CB internal parts. I suppose one alternative would be to ID the radio you want, either find a gutted one or make a mock-up of the exterior and then plug in your own CB equipment. Military radios and frequencies, as Wes has noted, are restricted and not authorized for any civilian use. Some CB route is your option. You could always look at a short-wave radio for HAM use.
I think that exhaust all my "good ideas" and suggestions!

Actually I have a AN/VRC-10 that works. It can be used on the 6 meter Ham band.

Try meeting up with Hams and have them help you out at a Hamfest. One of the guys who is knows in the community (like ours) will be able to guide you to good deals, ask the right questions before you plunk the cash down, and he may be able to work a better deal than you can get, just walking up.

Good Luck
Dave
