I'm not familiar with the push-to-talk adapter boards. I do know that the "HV" switch turns on a relay with a 120-Volt AC coil. Your PTT adapter should key that relay if you want to transmit. When we install the receiver relay in a Valiant, that switch is left in the off position. The mike turns on that relay when you key.

Leaves me with only two possible explanations. A failed component on your PTT adapter or an error of some kind in the hookup. I have more experience with the Valiant than I do with this model, but the way they both work for PTT is the same, best I recall.

Looking back I had to install a new Plate switch I’m wondering if I misfired or installed the wrong switch. Strange that IN Phone and switch OFF it keys with the Mike, I see all currents on the meter but get zero output from the radio? The relay on the K1 keying board clicks and works when Plate switch ON?

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
