Here is probably the best receiver I have ever used for finding stuff in the 225-400Mhz mil air band. This receiver covers 220 to 410MHz with continuous manual tuning and the way the tuning is setup you can cover a huge chunk of spectrum in a second and easily catch those quick, hard to find transmissions.
The receiver is all tube (and lots of them) but is very stable and surprisingly sensitive. After 15min of warm up you can set the frequency, turn off then back on months later and it’s still on the same freq you left it. The main audio out and headphone out is 600 ohm and you can simply plug in some amplified computer speakers with a 1/4” to 1/8” adapter for great audio.
I am downsizing my shack and hate to see it go and I will miss it. In the first two weeks I had this one I found more neat elusive stuff than I did with my Icom R-7100 in the 25 years I owned it. I have owned a few of these almost continuously since about 1974 and this is the nicest one I have come across.
Fair Radio Sales and Toronto Surplus both have these receivers but missing tubes and untested for $125. This one works great for about half the price! This receiver is heavy and shipping weight will be around 65lbs from So Cal. I also have antennas that I would discount to the buyer of this receiver.
