Forwarded from the Greenkeys list. Looks like an interesting piece of test gear: http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=370462778137 - John From: "George B.

When RCA succumbed to GE, a lot of them just disappeared. I still have mine and it still works like a champ. If the manual didn't come with that one let me know and I'll haul my manual down to UPS and have it scanned into a .pdf. You can either use it as a loop keyer, or, if you need loop power, it will provide that as well. You can send distorted signals up to 44 per cent switched bias, and can measure incoming bias and distortion as well. I never left home without mine. There is a built-in FOX generator that will do baudot, ASCII, Teletypesetter, and EBCDIC. And you got a very good deal. A friend of mine traded a new, unfired .45 ACP Match Grade pistol for one, and both parties thought they got the better end of the deal. The Beer Cooler Accessory was extra, but otherwise they were a repairman's dream. W7TTY
