Hi all,
The symptom of my problem is:
1. when setting k2 power to 5 watts, I get a reading of 2.2 amps with
abt 0.8v drop
2. when looking at power output with an external wattmeter, 5 watts
reflecting on the external wattmeter shows as 3.8 on the k2. Similarly,
10 watts on external wattmeter is reading 6.9 on the k2 at an 2.8 amps.
Cranking the rf power all the way clockwise shows 15 watts on k2 and hi
pwr message (cal curr set to 3.25) and external wattmeter shows 19
watts.
I examined T2 and had it too tight to the RF board so have re-installed
with gap. Part 2 alignment works perfectly, part 3 resistance checks
okay.
I do not have a signal generator that can do 0.14vrms so have not done
those receiver checks.
In performing the transmit mixer, buffer, etc, tests, the readings do
not look right at all.
Xmit mixer output (pin 4 at U10) reads 0.
Buffer output (pin 6 U9) reads 0.05
Band-pass Filter Output (W6) reads 0.014
T-R switch #1 Output reads 0.012.
Any clues or things to test?
Neal
