I got great info including some actual measurements from W4BQF that jived
with mine, once I took corrective action by shortening the power lead and
eliminating the dual fuses. Findings:
- starting T/S by eliminating the simplest (and most notorious) suspect is
still a great idea
- I was reminded my Astron VS-35M does not have voltage sense capability,
so some V drop shown on FP will be normal (but not 2+ vdc!)
- accordingly, to measure any voltage sag on my PS I must measure at the
PS terminals (K9YC et al)
- pay attention to the tx power indicator when operating. I had been
ignoring that until I noticed it was showing more power than usual (at
100W) after the fix.
FWIW in 50 years of soldering, the only connections I've had to repair are
the ones that were crimped but not soldered. This is a mandatory
anti-corrosion hack for salt water boating, along with RTV for good
measure.
I do not take the K3 sailing <g>
great info, great list.
many thanks!
