...just be aware that germanium is very sensitive to thermal shock during
soldering and unsoldering. They can change characteristics in pernicious
ways due to heating; and after heing them 4 times.....

I like the suggestion of cannablizing an old SWR meter ...    Have several
junked CB ones that might provide a useable diode or two Date: Fri, 4 May

With a slight reduction in readings.  Using a Schottky diode would be a
better approach.  I would replace both diodes in the SWR bridge with like
diodes just to keep some semblance of accuracy. Glen, K9STH

If it turns out to be a bad diode, and I cant gind a germanium, can I use a
regular power supply type diode to replace it?
