Title: Anyone recognize this radidio?
Post by: w3jn on February 04, 2005, 08:53:00 AM
Bought this on eBay for twenny bux.  A cool little crapstal-controlled SSB transciever.  All solid state except for what looks like a 6146 wrapped in a heatsink(!).  Has an internal HV suckply also.  1650 KHz IF, single crapstal per channel.  

It's about the size of a loaf of bread but a little deeper (picture makes it look bigger than it really is).  There are NO markings on it that would give a clue to its manuafacture.  Would really appreciate any info - who made it, when, manual/skizmatic?  It has a few problems (inverter transistors shorted, probably bad electrolytics in the IF, etc...) and more info is always better.

Thanks and 73 - John

Wow!  You da man, Pete.

I have a solid state Hallicrafters like this one also, except it's not gray, it's more of an OD brown.

Send me a PM with the manual price.

TNX!!!  73 John
