[Fourlanders] CQWWVHF @ W4ZST update

[James Worsham]

Wow, what a strange problem with the 6 meter amplifier!  Mine is available if 
you can't get Ron's.  Just let me know if I need to bring it with me Saturday 
morning.  The HV metering problem on the 2 meter amplifier is a known issue that 
has been developing for a while.  I agree that it most likely has something to 
do with the resistors in the metering circuit.  If you have a HV probe you can 
double check it.  If not, let me know and I will bring my HV probe.  Anyway, 
something else to fix!  For Saturday night can someone go into town and pickup 
some pizzas?  That would work for me.  Sunday lunch I would be OK with just 
sandwiches.  Again someone could go into town.  Weather here in San Diego is 
wonderful.  The sun is shining, temps are in the high 70s with a nice breeze 
blowing in off the ocean.

So far I have heard from:  N4NIA, W4KXY, K5AWC, K4VJM coming to contest 
and spending the night Saturday night.  We have more room available for 
others.  WW8RR hasn't yet committed.  We already have breakfast for 
Sunday morning taken care of.  Kos offered to cook and we have Pancakes 
and Bacon aplenty waiting for the occasion.

Latest development:  I have tested the 6m amp again and it is still 
doing the same thing.  Acting normal but no output.  It is not the 
wattmeter as I have used a different meter, slugs and jumpers.  A very 
strange problem as we don't know where all that power is going and the 
amp is not overheating or shutting down automatically.  It is definitely 
producing normal power with 1A of plate current and 60mA of grid current 
which only occur when drive is applied.  Idling values are normal.

So, we will need another 6m amp.  Either Ron's or Jim's and I know both 
are available.  Whichever one we can get up here, we will use.

A minor problem with the 2m amp.  It is not reading high voltage 
properly.  Probably something to do with the HV multipier string.  It is 
reading about half the high voltage, but the full amount is really there 
as I can easily load it to 800 W out and it wouldn't do that with half 
voltage.  It appears to be working fine otherwise so I think we can just 
use it and trouble shoot that problem later.

I have had both stations on the air.  Still connecting computers and 
such but I can easily finish that.

Any suggestions for meals Saturday night and Sunday lunch to be fixed 
here?  I figured that would be all we would need for the contest besides 
Sunday breakfast.  We can eat before the contest on Saturday on the way 
(or bring something up) and after the contest on Sunday on our own (or 
maybe some would like to go to Rooster's on the way home).

Haven't heard from anyone on a time server.  I can use one of my 
computers for a Writelog server if necessary, but I don't have my GPS 
thing working for time.  We can use the internet as we have done that 
before.  Is that good enough for WSJT?

All for now.  Bob
