[600MRG] Antenna help sought - SUCCESS!

[John Harper]

Thanks for the many private emails. I've got the antenna now resonant at
475 kHz and plan to be on WSPR tonight with my Ultimate 3S feeding an 80 to
630m down-converter from WA3ETD:

I've already tested this combination into a dummy load and it works FB.

As for the antenna, I figured that the VNA was at its limit of measuring
the values indicated so I put 15 turns of wire on the bucket and took
readings again, 100 kHz apart, from 1300 to 400 kHz. This time the
resonance had moved from 1300 to 650 kHz. Two more iterations of adding
turns now has the antenna at 475 kHz with a 2:1 SWR bandwidth of 22 kHz.

I'll start WSPRing tonight at 0100Z. Thanks again for all the helpful
suggestions.

73,
