Re: am broadcast break throgh

 

Mark,

Try replacing C72 with one just 4.7-22pf range. This will reduce the VFO drive and the mixer will get
lower 4th harmonic which is causing the AM breakthrough.

I use a Murata trimmer. The power out will drop a bit.

Hi all I don't know if this subject has been covered before but after blowing my raduino and converting my

Bitx 40 to analogue tuning I am having a lot of am broadcast stations breaking through the bitx.

Is there a mod or two to stop this?

If the subject has been disgust before could someone please point me in the right direction please.
