With a few helpfull tips from Don Wilhelm - W3FPR I
was able to quickly resolve my K2 power output
problem.
The voltage measured at diode D9 cathode (marked end)
on the RF board was 2.30 volts DC. After R66 (2.7K) it
was 0.0 volts. The microprocessor was NOT getting the
RF output signal via VRFDE
Joe,
The initial problem to be solved is that there is no indication of power
output being fed back to the K2 microprocessor.
The most likely source is a bad solder connection and the second most likely
is a misplaced component.
Keep your testing periods short, ignore the high current messages f
The build for K2 ser # 5628 has been going well until
I got to the "Alignment and Test Part III" 40 meter
transmitter alignment section.
Problem:
With current set to 2.0 AMPS and the power control
fully CCW I measured 7 watts on an external wattmeter.
The internal wattmeter had NO indication.
