Jeff, I'll get a USPS MO and let you know when I sent it.

Thanks,  Len

Love CW contesting too.

However, my skills are limited to about 25 wpm.  I don't use machines

to copy code so somebody blazing away at 40+ wpm calling CQ gets 

ignored.

Conditions seemed pretty lousy this time, lots of QRN.

Find more fun on QRP contests.  

72,

Tim Colbert  K3HX

Starting with the Paragon and with one exception of the pegasus, tentec uses
forward power and emitter current to limit drive to the finals.  ALC drive
limiting comes from 2 sources - emitter current and forward power.  They
have never used SWR for drive limiting.  The only problem with this system
is parasitic oscillation, which can cause high current in the finals without
drive.

The pegasus just uses forward power for drive reduction and does not use
current.

I use the same supply you do and Airpax breakers. 
18 Amp instant on the Corsair II and a 20 amp fast on the OMNI V.
I have never had a problem and have had the rigs for over 5 years.
You might want to check the numbers on those Airpax.
Look on the case and see if they sent the right ones.
Stranger things have happened.
You need to be extra careful with open line and a supply that put out  over 
20 amps.
Those finals will keep drawing amps, the supply will keep  dumping amps to 
the finals and, the finals will overheat and  smoke.
When your rig went out did the breaker trip?
Should have.
You never told us what they did prior to sleep mode. 
I can tell you that if my Corsair II smells anything over 18 amps with  
anything less than just a little over flat SWR especially on 20 meters it flat  
trips in a "New York Minute."
The instant is a pain cause it goes out right away like a fast blow but  
offers better protection.
The fast is fine goes like a slow blow.
The slow is useless. I tested one once and it tripped after the supply gave  
25 amps to the load.
Check those breakers!

Hi Robert....I homebrew my own connect cables...never did like the prepared 
versions at all for the reasons you specified...
One thing I do have here is not an antenna switch box...I use an old drilled 
out brass door hinge, bent at a right angle, that I drilled out the screw 
holes to install bnc male connectors. All of my coax RG 8X cabeling (I run 
barefoot) for the hf rigs go to that central "panel" then to respective 
transmatches, that feed either a 40 ft vertical dipole or a 100 ft doublet 
with capacity hats on the ends.
The vertical dipole is fed via a revamped Johnson Matchbox that a fellow up 
in Washington State built up for me that expands the matching network. 
Balance is excellent..if my xyl's computer speakers and tv in the shack is 
any indication as well as matching.
The big doublet is fed (currently with either a homebrew balanced linked 
coupled transmatch or an old Dentron Super tuner plus via its internal 
balun). I am having another revamped Johnson Matchbox tuner manufactured for 
me for that antenna.
Both antennas are fed with 450  ohm (for now) twin lead.
Have been hamming for over 25 years...facinating  hobby...still on steep 
learing curb!

Ok....8 feet....allow me a little slack and call it say 3 meters.  A quarter
wave on 12 meters.  Almost a quarter wave at 15 meters.  Thus probably not a
very good ground at all on 10, 12 and 15 meters.  Probably a good enough
ground at 20 meters and longer.  (Assuming 1 rod was enough in the first
place).  That was my point.  Hint....try a second (or third and fourth if
needed) ground wire in parallel with the 8 footer that is a half wave long
at the shorter wavelengths.  This will repeat the low impedance at earth at
the radio.  Think of it as a transmission line.

There is no breaker, never has been. That seems to be the consensus of 
what my problem is! Thanks.

Just FYI, the Nye Viking is the exact same tuner as the old Johnson - 
(with even better quality components) - they bought the rights to it. 
Found mine on EBay for $500. Can't say I like the metering, though...
