BTW - there is a LOT of CW activity on 7050  - 7060 kHz these days also.

There are frequently times thereare almost NO QSOs between 7030 and 7045, yet PLENTY of stations chatting above 7045 and up to about 7063 kHz.

Take a listen. You will be glad you did!

Much appreciated advice Howie,

    I'm looking forward to putting it on the air, hopefully TVI will
not be an issue, I have a low pass filter here somewhere :-)

    Eventually, not for a while yet, I'll go looking for a receiver
from about the same time.
