I fired up my ubitx V4 for the first time. When you turn the encoder, the frequency only changes by .050 the goes right back. I removed the encoder and used a jumper wire to try to simulate a encoder. Same problem. Then I removed Raduino, screen, and nano from the ubitx board. I supplied it with 12 volts and installed a 4.7 resistor on cw wires. I used a jumper wire again to simulate a encoder, same problem. Should I try to reload the nano, or do yall think the nano is bad??

Yes I remember this. Look carefully to see if you may have misinstalled the connectot. Mine had an extra plastic only pin, and is easy to misalign. Or missed solder somewhere.

This was a Factory nano from hfsignals. I removed everything I did during build up, plus removed it from ubitx board, same problem.?

Hi,

From what I read, I don't think it would be easy to simulate the encoder with a wire.? It needs timed make-break between the two internal switches.

Anyway, does the encoder press button work to get menus?? Does the encoder then work to change function options?

Do all the nano versions leave the version number up on the screen like that?? Mine disappears after startup.

73,


Mark.

The push button does work, but can not change function options after that. It leaves the version up there, not sure if it suppose to or not.

I suspect it's a connection issue between raduino and the main board. Support provided by proper assembly of standoff hardware is important.? I remember having to disassemble mine a few times and I experienced the same thing. If you are building into the case supplied by Sunil, those connections to the front interface board are easy to experience open and shorted connections. I really think it may be something simple.

Curt, are you talking about the stand offs between the screen and the raduino? I will try that tonight. Last night I removed the encoder from Sunil's board. I soldered it straight to the wires supplied by hfsignals, and added the 4.7 resistor on blue and green. I did leave the analog cable plugged in because I didnt think that would affect it. Same outcome. I will disconnect the analog cable tonight and try it.?
