[50mhz] tapetone

[Chris Boone]

Confirmed...it was designed for the National rcvrs...found this googling
"Tapetone 6m" :

40621.ba.v03_n668

For the list keeper, here are the models of the 6M Tapetone converters:

XC-51 -- 6M to 10-14 mc output (Meets the rule of thumb stating the first
conversion should be no lower than 20% of the received frequency.)
XC-50-C -- 6M to 26-30mc output (Mohawk?)
XC-50-N -- 6M to 30.5-34.5 mc output (National NC-300/303 series RXs)
XC-50-C4 -- 6M as two 2-megacycle ranges to 28-30 for Collins 75A4.

Note the "high tone" converters did not offer outputs in the AM Broadcast
Band or on 40M.  Breakthru and image suppression problems forbid that
save in a casual, probably mobile application.

My 1st rcvr was a NC300 and I ALWAYS remember it had 6,2 AND 220-225 on the
drum!! The input was noted in the manual as a 30-35MHz IF..
