[R-1051] Six pack attack

Thu Dec 12 17:08:45 EST 2019

But there were huge numbers of Sunair URC-92 that were out there, the GSB-800 and 900 were used on all type of small craft where longer rang was required. Going to assume that the URC-35 was maybe intended as a replacement in the sixties and seventies for short range and compatibility with regular marine traffic but with the death of marine AM in the early seventies that stuff was thru? Have seen GSB-800 installed in Navigation and on the bridge of several ships back in the day, have seen URC-7 and TCS installed on museum ships but the URC-35 is nowhere to be seen.
Wonder if the Huge URC-7 and the URC-35 were in service at the same time? Then again your web site shows a URC-8 that was in that time frame somewhat, I know the URC-25 was newer. But I have never see a URC-8 and other then the pictures you have I have not seen one and I did a6t least see a URC-35
Somehow always thought of the URC-58 as an off the shelf move to support shore and brown water navy in Vietnam, and may as a form of torture for the ET of the day.
But this is all speculation on my part, and as my wife will be the first to tell you I am often mistaken.

My (probably flawed) understanding -
By the time of their introduction, there was really not any call for an HF transceiver on larger ships.
The URC-58 (RF-301) transceiver was installed on smaller craft "pending availability of URC-35" - but I guess there wasn't much reason to replace the URC-58 with something bigger and heavier...
On larger ships, you had separate transmit and receive antennas. The receivers were doubled up for diversity for receiving fleet broadcasts plus ship-shore terminations. Fewer transmitters were needed because they just didn't need to do that much HF transmission - inter-ship relay and tactical circuits were UHF.
And then satellites came along.......
