As everyone knows, real RF ammeters are becoming scarce, or very
expensive. Does anyone out there have info on where to find a circuit
that is relatively inexpensive that I could use as a substitute?
Something using a toroid core plus diode, or something like that, would
be what I am

Yep. Google to find GM3SEK's
I couldn't locate the GM3SEK article (is it still there?), but this is
also useful:
http://www.w8ji.com/building_a_current_meter.htm
And I believe that QST and/or the ARRL Handbook has information on this,
also.

Jim, I sent you direct the construction info on my 0-100 mA and 0-1.5A RF
ammeter that includes photos and schematic. I hope your e-mail system allows
the attachments. If not, let me know.
This is an in-line ammeter, not a clamp on type.

Thanks to all who responded. Several circuits to try, so I am sure one
of them will work for what I have in mind. Again, thank you.
