k-po dx 5000+
Pyramid ps21kx supply
aligned by Scott's Radios
was "told" it does just shy of 50w am/fm/ssb
draw according to p.s.
8A on FM
4A on AM
2A on ssb
-mic gain and power 100% on all modes.
-regular contacts made on usb with signal reports of 5x5 to 5x7
-swr under 1.5:1 where i transmit
question is, if it was able to do close to 50w on ssb, wouldn't the p.s. be showing higher draw than 2A?
 

On SSB apply steady tone to the mic. Some audio generator. You'll see current draw.

voice can only get 2A, i set the roger beep tone to 10.00, and max time for the r.b. saw the 4A draw. i would have thought voice could have made the same. on the other hand, i do not whistle or yell at my microphone. thank you for solving this curiosity that had been festering a few of us. regardless if it is only doing 20w with voice or not, i refuse to run an amplifier. I'd rather be patient for conditions. take care out there

    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
