Re: New wiring diagram version
Adrien F4IJA
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 folder you will find the SVG source file :?/g/BITX20/files/uBITX%20CAD%20Drawings -- 73's Adrien F4IJA |
Re: UBitx v5 Not Saving Calibration or BFO adjustments with CEC v 1.20 Nextion

A quick look at the CEC 1.20 firmware! code Snippet from?void menuSetupCalibration: //save the setting ? if (digitalRead(PTT) == LOW){

? } Mark, are you seeing the text in the above printLines after you push PTT? (I think I'm in the correct place in the code) You may want to try holding the PTT button down for a longer duration. PTT is used as one way to break out of a while() loop, and it is re-read later in the code to 'save the setting' (pushing the encoder 'function' button is the other way to break out of the while() loop, when you DON'T want to 'save the setting') Potential of a glitch the way the code is written for a short push of PTT, but just think "hold PTT until I see 'Calibration Set'" or the corresponding message? for any of the menus. I haven't tested the code, just looked over it. Easy code patch to propose to Ian, if issue solved by a longer hold on PTT. Regards, Gary |
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 world-wide 2 way spot reports. ?Note that the other folks in the top seed have expensive professional gear and full power. Our uBITX is running with the bulls and keeping pace with only moderate/QRP power.
Sterling performance credit goes to the CEC-based CAT control, WSJT-X's ability to direct band hops, and the generally excelent TX and RX performance of the uBITX design. On RX in particular, the uBITX has proven to be a world class receiver of digital modes -- the rig has very good ears and audio circuits.? Here are the top 10 in deceding order of 2 way spot reports. The mightly uBITX is in 4th place (km4udx). ?The number of 2 way reports per band is shown next. ?Clearly the uBITX will work on more bands, but my antenna is the limiting factor. ?For example, last month I worked 160 with my 80-10 DIY OCFD. ?While the SWR was about >34,857, I kept the power down to 1 watt, and got a handfull of 2 way spot reports at medium distance. So 160m with no low pass band filter and no real antenna is no reason not to communicate. hahah.? All hail the mighty wispering band hopping uBITX! Yes I have cherry picked the data, but I get to do that. hahah Don km4udx |
Re: BitX40
The 8 pin connector plugs into the top of the Raduino as shown here:

? ?? and the green,purple,yellow wires from that connector are soldered to the tuning pot. Make sure all the spare wires from that 8 pin connector have tape over the ends. There have been several instances here where a Nano on the Raduino was destroyed when one of those wire ends hit something with 12v on it, perhaps the IRF510 heatsink.

Re: BitX40
The yellow wire goes to the pin at the end of the connector.

Pauls photo agrees with the "wiring up" drawing here: ? ?? except that Paul is showing the backside of the board. Note that the other end of the yellow wire goes nowhere at all. But it has 12v on it, so I suggest you put a piece of tape over the end. If that end brushes over the wrong spot, you can blow a part (or even many parts). I suggest you put tape over the end of all unused wires. The volume control is shown in that "wiring up" diagram linked to above, the text has been clipped of to read "UME" instead of "VOLUME" The Bitx40 schematic is here: ? ?? Under the schematic is a link to get a downloadable copy of the schematic, unfortunately that link is open. Yes, I agree. The instructions on the website should be better, the website needs editing. But you will have a working rig once you figure out those dozen or so wires, and that is much easier than building most SSB Transceiver kits.

开云体育Hi PaulThanks 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 control shown in the diagram. ?I suppose with a circuit diagram I could trace what’s where, but I’m rather cross that they can’t be bothered to post the pinouts on the web site.

Re: Builder for Disabled
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 with the build.?? 73 Eric? KC3GDV On Mon, Sep 2, 2019 at 11:59 AM Thom LaCosta <tlchost@...> wrote:

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 pin cable from a Bitx40 does work, just plug it into one side of the Raduino connector as described in the above post. Yes, this should be better documented up on hfsignals.com. But they may feel that the diagram at the top of?? is sufficient for most to blunder their way through somehow. It does show which 5 pins your cable should connect to, and the orientation. This is further described in post? ?/g/BITX20/message/66263 Jerry, KE7ER On Tue, Sep 3, 2019 at 09:29 AM, Roger Tuffin wrote:

Re: Speaker connection on jack
开云体育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 ? From: [email protected] <[email protected]> On Behalf Of _Dave_ K0MBT ? I have hooked up the wires from the radio to the ring and tip of the socket and left the base float. That way the jack becomes insensitive and you can plug in stereo headphones and both sides work or an external speaker with a mono jack. |
Re: Speaker connection on jack
I have hooked up the wires from the radio to the ring and tip of the socket and left the base float. That way the jack becomes insensitive and you can plug in stereo headphones and both sides work or an external speaker with a mono jack.
It is a good idea to solder the socket to a perf board and solder the wires to it. Will make the connection stronger. and have less stress on the socket. -- 73 Dave k0mbt |

I will try but i think i've tried also with encoder press; i follow this step: setup on , set calibration, zero beating with reference station like RWM, press PTT, setup off. On power on value is lost.
