Don - I'll try this - do you mean leave all the wires still plugged into the AGC board, but unplug the AGC board from the main PCB? And should I then jumper the two outside pins to "restore" the RF

Yes, please. Then un-jumper the header, leaving it open, and see if the feedback remains. Next step is to disconnect the S meter lead. Then short J1 to ground. If we can isolate the problem then we

Don, I have this effect after installing the AGC board. I hadn't done the twisted pair on the links to the volume pot so I did that. It almost knocked out the problem on 40 but still very noticeable

So far . . .

The S-meter and PO use pin A7. You will need relevant hardware mods to use the meter. Both functions can use the same pin since one only works on RX and the other only on TX. However this doesn’t

Here's my attempt at a 'transportable' uBitX. The box is a 'toy' briefcase and the display is mounted with a ribbon cable on the top surface. The gaps and perforations are for air flow as there is a

Here is my uBitx. The display is too bright and came out white. I use the RF gain, AF gain, tuning, band selector, Function and ANL controls at the moment. I reprogrammed the Raduino so that A7

Powering the uBITX down, reconnecting to MM and reading and decoding does not show the WSPR settings as I originally tried to write. I am using Windows 10. Just what is the Match Data box in MM

Very nice build. I plan on doing the same thing. I wanted something that fit in a backpack. I even have room for a 12v 7AH battery in the case. Thank you for the inspiration. Marco - KG5PRT

Thanks for all the replies. I will do the raduino update as well as the mod to mute the LM386. Should fix the problem. Great to have all the support. Cheers -- John VK6JAH

TNX Bill and I think Vince did the same thing. I received some boards from China yesterday that I forgot I'd ordered. I had to go to Paypal to see what 2 of them were. Looked liked great boards, but I

I really like that look. Where did you get that briefcase and how did you create the front face metal panel? I am toying with the idea of a setup like that or maybe an ammo box setup where I build

I'm thinking about using an Apache case from Harbor Freight. However, I need a way to cool the PA's with some kind of fan, but without destroying the watertight nature of the case. I'm going to use a

Is the fan quiet, or does the rcvr pick it up? Jack, W8TEE

This is the little briefcase I have. It came from Harbor Freight: https://m.harborfreight.com/11-12-x-7-12-x-4-12-aluminum-case-69316.html The board fits with plenty of space. There is also pleny of
