I'm knee - deep into building a K1
Last night - right before my mandatory bedtime I performed the receiver
alignment and tests.
Everything worked A-OK, with the exception of the S-Meter and AGC.
There appears to be no S-meter response, and the AGC does not seem to be
working.
With the K1 and my K2 connected to the same antenna a S-6 on the air signal
(as indicated by the K2 S-meter) provides no response on the K1 S-Meter. I
also cranked up the K-2 power to 100 watts to the antenna and monitored the
signal with a hank of wire attached to the K1 antenna jack - REALLY loud
signal, but still no S-meter response.
The K1 S-meter consistently shows one bar regardless of input signal
strength.
The S-meter bar graph test pattern (i.e. brief display of all the bars)
functions when DISPLAY is pressed.
I checked the S-meter zero and full-scale settings. If the S-meter zero
settings is adjusted with the SIG function, the S-meter bars increase and
decrease as described on page 53 of the manual, however there is still no
response to input signals. Adjusting the full scale setting similarly does
not change response to input signals levels.
Due to my assigned bedtime, I was unable to perform the voltage checks at
U1, U2,Q1, Q2, D2 in the troubleshooting table. Now, I'm at my desk at
work, unable to concentrate on my livelihood.
Please offer some suggestions so I can keep my day job!
