Re: uBitX CAT problem on 40m #ubitx #ubitx-help #ft8

I have the same issue with both of my uBitx’s only on 40 meters. Last weekend I was at Lobstercon and Dave kd1na on his bitx40 also suffered from RF getting into his but again just on 40 meters. The two I have and Dave’s are v3 boards. Also I will add that both mine are shielded and Dave’s has his in a metal case. I have found using a different antenna helps.. ie using a end-fed it will always suffer from RF getting into the mic audio, using a dipole normally no issues as long as it’s at least 50 feet away. My 80 meter loop also works well. Using my 160m doublet will cause the issue. 40 meters again is the only band this happens on.

I had the same issue with my Yeasu when I first started using Fldigi. I put snap on Ferrites on the audio leads and wound the control cable about 6 turns around a ferrite toroid and that solved the issue for me.
