On my just-completed unit, with a 12 V supply (11.6 V on the collector of Q6) I am seeing 1.2 W output (22 V p-p into 50¦¸) on key down, rising to 1.6 W after ~ 10 sec (25 V p-p). ?I removed C29, the dc blocking cap at the input to the filter and fed my signal generator (AD9850-based homebrew) into the filter at that point and measured the output into a 50¦¸ load at the input to my TEK 2247A scope. ?I saw a loss of 2.32 dB at 14.000 MHz, 2.49 dB at 14.100, and 2.56 dB T 14.200. ?This seems excessive. ?1.5 W is only a half S unit below the expected 3 W, but with a report of RST 319 it could be important! ?Guess I need to work on the lpf a bit.
