Title: RBC receiver info needed Post by: MICHAEL on July 03, 2005, 09:26:41 AM Gentlemen: I have a RBB/RBC receiver setup that I need to figure out how to put on standby mode while going to transmit mode. I down loaded the available info from BAMA. I did not find this information there. If any one could help I would appreciate it. Also I would like to know about the cathode follower circuit and how it works.
THANK YOU IN ADVANCE! mike N7QMM Title: RBC receiver info needed Post by: Vortex Joe - N3IBX on July 03, 2005, 09:24:22 PM Michael,
I have the RBA/RBB/RBC receiver lineup, and to my knowledge there was never a muting feature with any of them. My RBB was converted from a 2 to a 5 variant when overhauled at the Philadelphia Navy Yard in 1961 and "updated" with revisions. Unfortunately adding a mute wasn't one of them - hi! My suggestion would be to install a switch to manually disable B+, or insert something in the speaker output to disable the speaker. I did it the "cheap and dirty" way by just turning the AF gain down whenever I transmit.

To bad they did not design the power supply with two transformers. Then it would have been easy. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
