I'm looking for a Unicom or something like that. Just want to put a radio in my hangar to listen in on Unicom. Transmitting is not a concern. I have one of those AM/FM radios that look like a radio you would have found at the airport in the 30's and am thinking/hoping I can mount an older but modern aviation frequency radio inside with remote controls to the tuner. Other words a push button type radio probably won't work. Anyway just daydreaming and any ideas appreciated. I think the old style radio style I have fits the biplane scenario better.

I set up my old Escort 110 as a hangar radio when I had to pull it from the airplane due to the upgraded FCC frequency standards. If you have the rack or connector and a wiring diagram, it's pretty easy. Just a long wire for an antenna is sufficient for receive only.

However, a power supply might be an issue. IIRC, it was still pulling 1.5 amps at startup. That might tend to blow a typical 12v wall wart. I used a 2A power supply with an automotive lighter jack.

Finally decided an old handheld made more sense, and moved the Escort to my display shelf.

I had given some thought to exactly that Ron. I forgot to put that in my first post that an old radio that wouldn't meet current standards would work fine to. Just need a power supply.

I have several KX170B's, each with its own issues. They will fit a USPS flat rate box. $20 each to cover shipping.

I use an old scanner from Radio Shack as a hanger radio. Found it at Goodwill for $8. There are probably a few available on ebay or various other places.

I know I can do that, as a matter of fact I have a scanner there now but I'm trying to get this "old timey" look going. There are only two bipes on the field and only one flies, me. I'm already the weird guy that flys around with old technology!

Amazon has several 12V 2A power supplies that would probably work.

Mine was actually a Radio Shack power supply that had the jack for a cigarette lighter plug. I see Amazon has several similar units for $10-$30.

You'll also need a speaker, of course, since the radio won't have one built in. If you've got a pair of old computer speakers, you're ok there...use the one without the power connection.

I also pulled the Escort 2 from my airplane when the transmitter crapped out (it had replaced the 110) and rigged that up as a desktop radio, too. It's just five connections (+/- power, speaker & speaker ground, antenna). Used it to test headsets.

Finding the pinout for the radio might be a little challenging, and if you don't have the rack for the radio, it might be difficult to hook up to. I got the schematic for my Escort 110 from Jim Weir of RST. Not having the rack is not a killer, if you don't mind soldering wires to existing connectors.

REALLY old radios that use vacuum tubes probably can't be resurrected, unless you're a serious antique geek. Also going to suck down even more power.

Here's my radio collection...none of it hooked up.

Yeah, but how do I keep the house lights from dimming when I hit the PTT switch on that big mother in the middle? :)

Most scanners are FM, but aircraft radios are AM. So watch for that if you’re buying a scanner.

I fly a plane that still has a directional gyro just like that one. 1944 OEM equipment!
Gotta watch those old instruments. I've been told the radium paint used is so "hot" that it'll set off the radiation detectors at airports....

Time to find a Geiger counter...
Look at the very bottom of the picture I posted, on the right side. That yellow and black thing? Geiger counter (actually a Civil Defense Radiological Survey Meter).

Are you sure you're not a ham radio guy, Ron? :D
