View Full Version : Vehicle rigs that pick up aviation frequencies

Hey folks-

I'm a pilot, and I've been getting more and more interested in Ham radio. I'll probably go for my basic ham radio license over the summer.

I currently have a VXA-700 by Vertex Standard (same as Yaesu I'm told) that I operate mainly for communicating with friends in their planes, and as a backup radio if my comms go out (in the plane).

My question is this: I want to put a radio in my truck.
One that is 2M and that can listen to Aviation frequencies, and (this is the part that is questionable) can transmit on aviation (VHF 118-136.975 MHz).

Are there any models that can transmit 2meter (or something else) AND aviation? Or that can be modified so I can transmit?

Not looking at doing anything illegal. Just some help or advice would be appreciated.

Thanks guys.

Pretty much all 2-meter xceivers will receive air freqs. My Kenwood TM-261 can be modified for wideband transmit, which includes the aviation freqs.

BUT

Aviation uses AM and 2M rigs, at least the cheap ones I use, only xmit in FM. But look around maybe someone's making one that will do AM and FM out-of-band.

That's the thing, I haven't seen any models that will transmit aviation and something else.

Can these things be modified to do it?

Probably not - usually "mods" are to remove a limitation that is imposed due to legalities or practicalities, whereas AM is not a typical mode for a 2M transciever. It used to be back in the 60's, according to my late elmer (ham radio mentor), but not nowadays.

You might be able to find a 2M rig with AM transmit capability (some of the do-all rigs might have this), and you might even find one modifiable for aviation freqs, but by the time you do, you could have spent better money on two radios.

Yes, I know aviation xceivers are expensive but I guess the logic is that anyone who can afford a plane can also afford to pay triple for a radio ;f

Exactly. They'll charge you $1700 for a bare bones unit with ten watts. ;g

I don't own my own plane, and probably never will. Too expensive, and I can buy a lot of cool stuff for the price of a slow plane :cool:.


But I see what you mean with the AM.

One other thought, transmitting on aviation with a modified ham rig would be in violation of FCC regs.

http://wireless.fcc.gov/aviation/fctsht4.html

"You may only use your hand-held aircraft VHF radio from your aircraft, or under the authority of an FCC ground station authorization. Ground station authorizations are usually only issued to aviation service organizations located on airports, businesses engaged in pilot training, aircraft manufacturers, or persons engaged in chase-car activities related to soaring and ballooning."


"Radio transmitters to be used in aircraft must be type accepted in accordance with Part 87 of the Commission's Rules except that radio transmitters to be used in conjunction with aeronautical public service frequencies must be type accepted in accordance with Part 80."

WI9NDY raises a good point.

There are very strict rules about talking on the aviation freqs and chattering with pilots from the ground is generally verboten.

You're probably better off just getting a scanner or 2M rig with wideband receive and just listening.

Also as far as a 2M rig with expanded receive, some will only receive FM. If you want to receive air band make sure it has AM capabilities.

Icom IC208H has AM

That's a good point. Wasn't sure about it.

Thanks for the info.

My Icom 261-A receives AM in the aviation band.

There was a 2meter/Aviation handheld that I was considering but I don't see it in the catalogs now. I don't remember the make & model but it may have been Icom.

That would make a great choice for aviator hams because you could use it as a backup comm radio while flying and hit the local repeaters once you're back on the ground.

There is supposedly a mod you can make to an Icom IC-T7H that will enable tx in AM. Seems to require quite a bit of soldering.

Find an older 2 meter all-mode rig.It might be a little large for a car,but it'll do the job...
