Re: Anyone seen an SSB xmit causing the menu to pop up?

Hi Gwen,
I had something similar on both SSB & CW.? Part of my problem was my 3amp laptop power supply was shutting down.? It reset the radio.? I got a 5 amp power supply to fix that issue.? After that, I had display issues, like you are describing.? I seemed to lock up the nano.? The screen would be on and the radio would transmit but the screen was blank and it would not go back to receive.? I fixed this by putting a clip on ferrite over all the wires coming from the Raduino.??
Interestingly, it only happened on 20M.? That is where my radio seems to have the best power efficiency.? I was using a 50 ohm dummy load when I was having these issues.??

Hope this helps.

check if your supply voltage is dropping on 'hellow'.

Perhaps local radtion due to left over mismatch.
?It might be wiser to shield loose wires to/from audio amp /agc? by shielded wires and shield grounded on one side.
Also the power reaching to raduino could be passed thro a diode say 1N5401 and filtered by 100uF parallel 100nF.

All the best

I too have seen this. I have yet to sort mine out and usually for me happens on an antenna and not the dummy load.

I was testing into a dummy load and noticed that when I whistled into the mike, or even spoke into it on higher frequencies, would cause the rig to react as if I had pressed the button on the encoder. It showed "Band Select >", and receive stopped. Pressing the encoder twice exited the menu normally. Is this RF getting into the switching transistor the encoder switch trips? How can I prevent this?
