Most likely the torroid chokes.. Hot melt glue or wax them in place.73 de Mike

When I say "microphony" I mean that the circuit boards are acting as a microphone - any slight tap on the case can be heard loudly in the phones. I haven't tried it on transmit yet, so I don't know

Thank you, Kurt, will find and download these photos for future reference. MicroBitx is now working, had installed what I turns out to have been a corrupt version of the latest KD8CEC sketch, BFO

It is on the raduino. I think it smooths the line to the demodulation stage Sent from my Huawei Mobile

I am / was really enthused about the ubitx concept. I really dont mind doing the mods or the cost. My main issue is not wasting time on a mod that doesnt really work which is why I want the designer

Hi all, it was received in this way by HF signals so I guess it was damaged by mistake. As reading all the comments it is pretty shure that it was accidentally so I will bent them back to their

What do you mean exactly with 'bit' of microphone? If you refer to low average SSB output, I replaced to add another resistor (47ohm)in parallel to R63 and worked nicely. However late November Barry

Older versions had the NANO mounted on the front of the board, soldered in place - If they put a socket on the front, the NANO would stick out too far and and short against the back of the display

I have also received boards like this and all I did was use a smooth jaw nose pliers to bend back the pin to right angle and plug it in. Thats it! Raj

Evan, we don't have to become Jamesbond, on this issue, normalize and use them. All the best

Jeff, It is simpler than it looks. 1: Open the Arduino IDE 2: From the files / open menu in the IDE, navigate to where you unzipped the KD8CEC archive to and open the file named ubitx_20.ino This will

Hi Jeff: The order doesn't make any difference. The IDE will arrange them alphabetically on the tabs in the IDE. However, if your files are such that only the file containing setup() and loop() is

I have attached screenshots of the settings I use in both wxjtx and js8call. Both work well for me and I have had lots of QSOs with both Brad KG5SPR [email protected]> wrote:

My curiosity is why it was mounted this way.? It requires that you purchase nano replacements without the headers soldered in place, as they are upside down from "normal" installation.? It also

I use a piece of the small tubing like they use in aquariums.? 1/8" ID and 1/4" OD.

Hi Jack... I have a simple problem. I don't see any information on which ino files are to be put in sequence in the Arduino IDE if necessary. I coped and pasted each file into the IDE and it compiled.

Ah, ok. Mine is V3 so built t'other way up.

Hello from a newbie! I've just completed the build of my uBITX and I have to say, I'm impressed! Just one little niggle - and I'm sure I've seen it mentioned somewhere but I can't remember where - I

It is for both of the v4 boards that I have purchased.,? Also for the one Raduino clone as well.

Curious that the Nano and 7805 have been mounted on the rear side of the Raduino board. Is that standard now?
