RE: K3 full power strange behaviour

[Joe Stofko-2]

Max,

   I also noted this with my K3 last week.
My guess is that this is a burp in the latest
firmware.  I tune my amplifier with a string of
dots (abt 30 wpm) and note the bar graph takes
about a second and a half to indicate an accurate
power level...

        Anyone else seeing this??

When running ARQ Pactor with my K3, I notice the power level seems to
wander requiring the mic level to be adjusted, this is noticeable as a
change in ALC indication. I suspect those running sound card data modes
may also see a similar variation in ALC levels. Note, I am not running
power levels any higher than 50 Watts, usually 15 - 20 Watts. By
comparison, a TS-480 doesn't vary at all.

Just been operating cw on 80m at 100w and after a while of 'everything normal' I noticed the power dropping and then coming back up...one time it went as low as 24w and then jumped back up. Power indication on VFO B follows the power drop, SWR seems ok but I confirmed it was doing same into a dummy load; PA temp was showing about 39 C only.

Seem to remember the same sort of thing happening a while ago but so long ago I can't remember if it disappeared with a firmware change or what.
