Good luck, Don, W5QN Original Message From: John Boyle via Collins Sent: Thursday, Decem PM To: Collins Subject: {Collins} 75S-3B S-meter I recently picked up a WE 75S-3B that had contained tubesters. The seller. Collins Amateur Band receiver 75S-3B: AM / LSB/USB / CW with BFO and product detector, notchfilter (rejection-tuning). Covers fourteen KHz segments in the range 3,4 - 30 MHz. Selectivity kHz (SSB), Hz (CW), KHz (AM). Accessories: speaker B-3, station-console B-4, many different xtal-filters. Matches the 32S-3 transmitter. The 75S-3C, or the 75S-3B mates with the 32S-3 or 32S-3A transmitter. Assuming you want to transceiver, but not do cross band, there is little reason to buy the expensive "A" model. The band crystal frequency is provided by the receiver, so a 75S-3C and a 32S-3 will operate on the WARC bands just fine when transceiving off the receiver.

One modification, that is described in Collins Service Bulletin #2 for the 75S-3B / 75S-3C, is also applicable to the 75S-1, 75S-2, 75S-3, and 75S-3A, does make a marked improvement in the performance of those receivers. The Service Bulletin only refers to the 75S-3B and 75S-3C because those were the only receivers in production at the time. 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. Optional , , or cps Mechanical Filter offers sharp selectivity for CW.
