[600MRG] 630m noise

[Edward R Cole]

Yep.  Most of us are stuck with some kind of 
short vertical.  Mine is 43 by 122 foot 
inverted-L, base loaded with humungous coil.  But 
it works: 100w produces 4w EIRP.  I tried a 1/4 
WL BOG and noise floor was 20-dB less but so were 
the signals.  I ran it parallel with my 
neighbor's 3800-foot airstrip but had to remove 
it for heavy lumber equipment access.  I do plan 
to make a 6-foot rotating loop (someday).

My eme projects taking too much of my time.
