[Lowfer] RF Ammeter recommendation

[W1EOF]

Hey Guys -

I hope to be at-it by this Fall, at least that's this years target date for
getting my lowfer beacon on the air from R.I. I just received some
information from a guy who is selling some analog RF ammeters. They come in
various F.S. values of 1-4-6-10 Amps. I have wanted one or more of these
guys for awhile, but I'm wondering which range would be the most helpful for
lowfer work?  Thanks.

73,
