Good on Ya, John...

Wondered if you were away...  This #4 wire loop lives inside of 100' 
sections of good garden hose...
The hopefully high resistance pine brances are good stakes @ 70+ feet...
Actually, the only high voltage points are here in the shack where it meets 
it's variable vacuum cap and coupling...


So far no tree fires...

'G'... Thats the answer fer sure...  Effective height...  The only sound 
loop advice I ever got before Bill Ashloop era usta be, the MOST real ESTATE 
( square footage ) inside the loop as possible...

I'm hoping to see how long this one will last as I place new and improved 
'parasitic' loops in the near field ( parralell ) becoming critical coupled 
in the hopes of lowering this ubiquitious 'R' value...  If we only had some 
negative resistant paint...

Finally rationalized why all the big time 600M stations were on the salty 
water coast... Although you can notice the attenuation even 3 miles in from 
the beach here, the 23KV 3 phase lines that go by here on the way sure looks 
like a long terminated beveredge to me pointed straight on the great circle 
to EU...

Duty free gift, I recon...  Now for the QRN reduction program...  You 
cracked the code OK on better and best digi weak sigs detectors...
WSPR making good show from EU lately...  Must get QSO version... If only 
peanut whistle 20 watters could fly...

Until the sound of,

Dave
