Re: LF: VO1NA

Hi Joe,

Sorry about the coil heating difficulties. Is this something new? I
need to investigate my system for heating. I see a small but
consistent change in apparent antenna system resistance during 2
minute WSPR transmissions since I increased power. I suspect this
may be due to core heating in the matching transformer but need to
confirm. It doesn't seem to present any operational difficulty but
is something I want to better understand.

I will welcome a chance to listen for your CW another time. In the
past your QRSS has at times been clearly audible in the headphones.
If you are interested in two way QSOs I would certainly be
interested to try with you. I have a bit of work to do getting my
QSO capability reinstated following some station upgrades over the
summer. I am waiting for a batch of connectors to arrive but this
should be sorted out in a week or so.

73,
Paul
