"Snap-crackle-pop" - My 8877 amp is out of service until I solve 
repeated HV arcs in the HV supply.  At this point it blows everytime 
I key PTT at which the G3SEK board disables with Anode alarm.  So I 
thank the 21 stations I worked last night - it was fun while it lasted.

I will now open the HVPS and troubleshoot.  Probably going ahead with 
conversion to capacitive filter and other mods I have previously 
described.  The flashes are coming from the PS so something is 
breaking down under load.  If it is the existing oil caps they can be 
replaced.  If it is the HV transformer - well I don't know.  Stay 
tuned for more entertainment ;-)

I will set up for 432, as planned, starting at 1200z Oct. 31 and 
running to 2000z when I run into my azimuth limit.
432.067 JT-65B, 1st:  4.9m dish, 85w
