Re: QDX: RF sweep shows notch at 20m


 

Hi John,

Thanks, that certainly clears things up a bit.? When I adjust the turns spacing -5dB seems to be about the high water mark so I'll just leave it there for now.

?

For reference, this is a QDX Rev 5 that I purchased in April of 2023 and then promptly lost in a box until about four weeks ago.? Despite the notch I'm still able to operate with it and have been having fun with FT8.? This is, however, a great excuse to get a QMX.

Cheers,
John VA7JBE
