Re: Ubitx v4 Raduino goes into Band Select menu during modulation


 

I had the same issue, however on 20m.? Traced it to rf riding the coax braid back from an off center fed dipole (MFJ-2010).? Solved it by grounding the shield before the radio, and placing a ferrite snap on core over the coax (RG8x) between the ground point and the connection to the radio.

Tried the ground only first, and it helped (could raise the power out to 6 watts), then added the ferrite to get it back to peak at 14 watts without causing the menu selection.? I did not have any issues on 40m.

My setup (using RG8x, PL259 connectors and PL259 Lightning arrester for grounding) is:

uBitx ======== SWR/PWR Mtr== Arrester ======== OCFD

Hope that helps.
