Just an FYI, I found out what the problem is with my modified KBPF3. I
removed the added caps and signal levels returned to somewhat normal levels.
Adding a cap to C2 didn't make sense and attenuated the signals. But Fig. 14
shows adding a cap to C4. Apparently the ham I bought this from
Erik,
Yes, using auto ranging on the DMM can cause false readings. Try to set
the fixed range a bit above the highest expected resistance for the best
results. It all depends on the voltage the DMM applies to the circuit.
Too high a voltage can make ICs and transistors conduct causing a
Hi Don,
Everything appears correct and in place, already used magnification to check,
and individual resistors all seem to measure correctly. I still think it's my
multimeter in auto mode. I went back and retried the initial test using manual
ranging and if I set the range to 600K it shows a
Since that is the case, check the value of the resistors and check out
the soldering under magnification.

Hi Don,
Nope, D3 and D4 are correct, and the LEDs check out per the test...
If anyone needs the external 6m preamp for an original K3, I have one I
would part with for a reasonable price.
