Hello all! So all works grandly with the hard working long suffering V4 except for 30m on TX. Almost no power. When I look at the schematic, it’s not obvious (well to me!) what relay/filters define th

I has a particularly bad problem with the in-line switching power adaptor for my cable modem. I wrapped both the AC power input and DC out cables several turns through large toroids. Then I found a di

You might try a line interference filter. Might also try shielding the offending interference generator, but might have to consider cooling airflow, so would not be to enclose it in a metal box - woul

Turn the offending devices off and back on one at a time to determine which one(s) are contributing to the problem. Depending on the nature of that device(s) it should be possible to apply any of seve

Help! I have a QRM problem if in the vicinity of the bitx there are connected electrical devices such as: swictching power supplies that power hard disk etc ... if I turn off all the QRM disappears Ha

I think you missed what the man is saying. He's working with the original bitx20 kit that was around before the Raduino and uses an FLL board with a PIC and LCD display. The FLL also supplies stabiliz

Greg Unless you have something that is really strange, the processor is not a PIC device. It is an Atmel microcontroller on an Arduino Nano PCB which plugs into the Raduino PCB that drives the LCD dis

I have a bitx-ver-3c-SBL with the 2 line LCD that is not working. I suspect it is the PIC processor as I tried other LCD. The symptom is no characters on the display. The unit work at one time years a

Gary, Is it possible to remove the Raduino and display from the case and connect to the USB port on your computer without the mainboard? The Raduino should powerup and the display should show the norm

Thanks yes I did. I took the digi board completely out of the loop. If I put the original nano in the radio acts as a normal v 4 ubitx. I can't figure out why these replacements won't work?

Somewhere I read that after some changes were made, the V6 had to be turned off and back on for the changes to take effect. I think there was a few seconds delay in turning it back on required (in the

Gary, Did you try powering up the rig without the USB connection to the Nano from the digi board? There may be an issue with the digi board. 73 Evan AC9TU

I don't think I worded my first post very well. I am trying to install a new nano board. The v 4.3 sketch loads properly no errors when it compiles or loads. This board seems to be the identical physi

Hi Gary, I flashed a spare Nano or tried to using the IDE Software with verbose ticked for the Upload option. It kept failing with a can't sync 500 error. I found I had to select the OLD BOOTLOADER op

I've RFed an Arduino Uno in the past and scrambled it. Had to reprogram it and it was fine afterward. Give it a try rewriting it. When I RFed the Uno some of the functions were still working, just not
