I got one at a hamfest 2 years ago for about 60 bucks and I think that's too much! It is definitely a technician's special -- a bit flaky. It had been partly built, never tested -- you need to get the right crystal for the proper receiver IF. Surprisingly, the company (still exists) had crystals for an odd 20 Mhz IF (old RF Communications VHF rig). I got it working on transmit (though flaky lock on the top end of the band), and haven't gotten to the receiver because I haven't realigned it for 2 meters yet. If you like to mess around with older technology, it's a fun bet. If you want something that works out of the box, let the buyer beware.

Does anyone out there know/have a simple to build amplifier which can say increase this to a few kilometers but retaining the simplicity of the oscillator section? A simple schematic would be nic without needing too many hard to get parts, maybe using a 2N3866 and air wound coils. Anyone out there with design expertise?

Are there any mods for this receiver? Does anyone know what the second button in the battery compartment (under the battery label, by the RESET button) does?
