Isn't it just amazing that in the middle of a world war, someone could bother to be upset by "4Q" ? Maybe in between machine gunning people and dropping bombs on them ? Sheesh. 73 de Gary, AA2IZ ____

Its true. You can copy CW in the worst of conditions. Next come the narrow digital modes. Then the wider digital modes. Finally SSB. It all depends on what you want to do and when and where you want

Aside from the NEC requirement, if the two grounds are Bonded (heavily) then there is NO voltage difference at all. Not so ? You definitely should not have your tower ground and house ground tied tog

You will find "good" used batteries sometimes, in some places. If you do, they can save money. If they turn out not to be so good, they will be a total waste of money. Your mileage will vary. I belie

I'll bet that the battery voltage, as delivered to the actual radio, is a little low. Going to a sine converter and 115 VAC power fixes this issue totally. Gary will even Paragon to voltage the optio
