[Elecraft] K3 output power spikes

[Guy Olinger K2AV]

Power supply stability. Built cheep, get worse with time, insufficient heat
dissipation due to endless complaints about fan noise, cut corners on
components, too small wire to rig, yada, yada, ad nauseum. Power supply
issues can cause rig overheating, spikes, slow power build up, unstable
power output, audio distortion, hum, frequency drift, broad signals, even
key clicks, various issues with following amplifiers, just to get started
on a long list.

Plus the still-valid old timers' warning: ALWAYS do the work to RULE
OUT external issues -- connectors, cabling, coax, antennas, programs, power
supplies, misunderstanding or ignorance of the manual, power spike
scrambling memory, braine pharte, BEFORE tearing apart or sending rig back
to factory, or deprecating the manufacturer on public media.

Sticking to that rule over a lifetime will save 90 per cent of angst and
trouble relating to station apparent rig malfunctions.

73, Guy K2AV
