Comments:

There was a solar C8-blast at 1630Z for the daylight zone, 
and we went through the 1900Z session at B3-level straight. 
A lot of slowly decaying electron content in the F2 layer... 

Nothing wrong with the Dentron MT-3000A tuner. I guess, 
the contacts of the antenna relay of the LK-550Z have 
failed, as the 3 tubes had a "healthy" orange glow on 
their cheeks, but the output was jumping erratically. 
Time to put the screwdriver to anti-clockwise action, 
and hopefully some reverse turns soon after. At HF the 
relay can probably be replaced with the OMRON G2RL-1 
or G2RL-2 regular AC-relays with 8 amps contacts. 

The series of FTDX10's in test are a bit problematic. 
These seem very sensitive for SWR regarding parasitic 
oscillations of the PA-stage. Also the second one 
did only put out 10 watts on 70 MHz. I guess, I will 
not take a third one for scrutiny... The receiver side 
is excellent though...  Cheers/73, Zaba OH1ZAA #1856
