Eric Wonderful offer. I don't know Thom but remember him from qrp-l. In my judgment a small team of builders can take turns working on his rig, in parallel with your own rigs. Important is to find out

Good to have an alternate drawing of how to wire up a uBitx. We often have questions here from puzzled kit builders. However, The 2 reverse protection diodes should be after the fuses, not before, so

I ordered RMItaly KL203 and will give it a short to work with ubitx once it arrives here.

Hi everyone ! OK, you'll now find the new version of the wiring diagram in the wiki : /g/BITX20/wiki/uBITX-Assembly You will now be able to download an HD PDF and also, in the CAD

A quick look at the CEC 1.20 firmware! code Snippet from?void menuSetupCalibration: //save the setting if (digitalRead(PTT) == LOW){ printLineF1(F("Calibration set!")); printLineF2(F("Set Carrier

Hi, is the same only the one in my instructions is turned 180 and has another board on top. All connections go to that one not the display one. Got mine from hf signals. Good set of parts and lots of

We all love our uBITX. ?Did you know the uBITX makes a wicked good digital mode beacon station using WSJT-X's cool beacon mode called WSPR? Well it does. ?We have a uBITX tied for 4th place in

The 8 pin connector plugs into the top of the Raduino as shown here: http://www.hfsignals.com/index.php/2017/11/23/wiring-up-the-bitx40/ and the green,purple,yellow wires from that connector are

Sorry Jerry. Looking at the schematic I meant tuning not volume. Where do a connect the tuning pot on my board as I only have the 8 way connector other than the pins some of which I’m using for the

Thank you Jerry. I will take a look tomorrow. 73 Roger, M0TJK

The yellow wire goes to the pin at the end of the connector. Pauls photo agrees with the "wiring up" drawing here: http://www.hfsignals.com/index.php/2017/11/23/wiring-up-the-bitx40/ except that Paul

Hi Paul Thanks for that. So does the yellow wire go into the pin nearest the 575 handwritten on my board? Only your board looks different to mine. Also, what happens about connecting the volume

Thom I am with the Anne Arundel Radio Club and there are a few of us that are building the uBITx and the Jack AL board. If you would like to join us please let me know. I am sure we could help you

Can you explain? I tried with once push of the encoder but nothing changed

Roger, the Raduino connections are confusing but all is necessary is to plug the 5wire connector as show is the attach. Actually the extra connections will be useful for future mods. Works okay

Roger, All Raduino's are now built to be plugged into a uBitx, all that has changed is the connector. (But note that the firmware loaded into the Raduino is different between Bitrx40 and uBitx.) The 5

Thank you Vaughn. I would agree with you but sadly, my Raduino connections are not like the one in the picture…. see picture below. Roger, M0TJK

I too have one of these, great little builds but you do need to research. Best instruction I've found is here http://www.hfsignals.com/index.php/2017/11/23/wiring-up-the-bitx40/ Best of luck Vaughn,

I bought a BitX40 last week. Checking the contents on arrival, there is a 5 way connector which is supposed to plug in to a 5 way connector on the Raduino board. Except there is no 5 way connector on

Hi Dave, I did the same on my uBITX speaker jack. It works but it was difficult to solder, and the end result is not very pretty. The PCB is a great idea. 73, Jim KX4TD Sent: Tuesday, September 3,
