RTTY BA INFO NEEDED I picked up the folloing 2 BA RTTY items over the wekend and would like to get some documentation on them...
Boehme Frequency Shift Converter Type 5-C. This is a 10.5 inch black rackmount unit with a 2 inch scope for a tuning indicator. It has 16 tubes including a string of 4 6Y6's. Very impressively built--looks like it should be military but has no mil tag. The front panel is 1/4" thick aluminum! Type CRV-35049-A Tone Keyer, part of Model RDM radio equipment, made by RCA. On the back it has a paper tag that says "Model TK-43B Tone Keyer" and one of those old RCA unit numbers: MI-17106-B. It is a 7" high gray rackmount. Was this designed for repeater service? It seems to have connections and controls for taking a "Diode Load" signal from 3 receivers. This looks like a top quality piece of gear. Any help with either of these would be appreciated. Thanks. 73, Don Merz, N3RHT
