This Collins 75S-3B receiver is a late winged emblem
receiver, serial number 17XXX. It incorporates the later improvements that
were provided in the round emblem receivers, including T-9, the filter
cover on the top chassis and the cover on the bottom chassis. I purchased
it from the original owner. He purchased it in February 1967. This receiver
has the SSB filter and has room to plug in 3 additional filters.
The 75S-3B receiver can be combined with the 32S-3 transmitter and 312B-4
station control to make a completely integrated station. The 75S-3B,
when used with the 32S-3, is capable of transceiver-type operation with
the receiver PTO controlling the transmitting frequency. The 75S-3B can
also be used conveniently with the Collins KWS-1, as well as the Collins
KWM-1 or KWM-2 Transceiver.
Other features include:
- Rejection

can also be used for CW and RTTY.
