[nrv-hams] Possible HF setup

[Cam Coble]

Your call sign as a pattern may be the ticket! LOL!
As for patterns, I would recommend trying a few things. Get some Command
Strips or something you can stick/restick and play around with it. You'll
definitely need a tuner but it could be fun. I think the article I sent,
the guy did a big rectangle coil, but I think a big Z may do a better
job, or just the largest rectangle you can get. Keeping the power low and
checking the SWR you will find something that works enough.
73!
