Jack, Glad you got your issue resolved. BTW, I also use Reed's very well coded and solid firmware. I have only made some simple customizations/personalization to it. Regards, Gary

Thanks.

Please try out itshamradio.com/bfo-tuning-aid-ubitx/ The code is little refactored to suite all the java script nuisances by popular browsers. The same logic is retained, as the orginal uBitx Tuning A

Hello Everyone, I agree with Tomasz and previous observations that the receive sensitivity of the ubitx radios, especially since v5, is generally really good. I have noticed that above 15m, receive se

The best way I've found to frequency calibrate my ubitx V3 is to use WSPR. Based on all the reports you get, you can generally tune to within 10 HZ or so.

Is there a version of the firmware that will work with FLDIGI's cat keying option? I'm Using N8ME's version and while ptt activates, no code is transmitted. I've tried both RIGCAT and HAMLIB set up fo

Hi Loris, I have installed that circuit on my uBitx v5 and have not noticed any significant reduction in volume in the presence of a strong signal. Maybe I have tied that to the first IF instead of th

VU3EEY, Were you able to adjust the bias? If so, then I would look at the driver and pre-driver stages, checking the voltages per Raj's spreadsheet: https://groups.io/g/BITX20/filessearch?p=name%2C%2C

Win 11, CH340 driver's advanced port setting require setting changes to work with Nano. FYI, I just changed over to new laptop with Win 11 and needed to program a Nano. I could get the board info (as

Thanks Gary, On mine I thought it was the connector on the PCB but it was like you said the strain relief cutting through the insulation. I fixed it and it is now working fine. 73, Yvon AE7YD

Hi Roland Only a question, why one file it has bootloader? 73, de IK0XBC Andrea

I plan on using this thread as a build thread, and a more detailed one on my blog

Evan, The confusion is on my part. I used the word tone, but I meant sine wave at frequency x and y. You were perfectly clear. I haven't had a chance to work on this just yet. Thanks for the help. Tha

Hi Merle, Logically, it looks like that would work. However you need a current limiting resistor to the LED. I haven't built and tested the circuit. But a starting point bias would be ~1.64V, 10mA. So

Greeting, Due to lack of space, I have to reduce my equipment collection, so I am selling my uBitx v6 with Nextion display. I live in Germany, so it would be good if someone from Germany or the surrou

Will try that 20KHz one. Thanks and regards, Ashutosh

David, The ND6T AGC with board designed by KitProjects has been released. Files are here and the build is reasonably quick. Gerbers and docs are at the link. https://groups.io/g/BITX20/files/Kit-Proje

Sorry to hear that Aaron. I finally figured out what my problem was. As usual it was something silly. Dan KD3CEU On Saturday, March 4, 2023 at 02:45:59 PM EST, Aaron K5ATG via groups.io <k5atg=yahoo.c

But Brad and everyone else, A valuable lesson was learned. I did a similar thing with my new Astron 35 A power supply… It has current control and it was turned down to almost zero when I first tried i

Thanks! AC9TU. you are right. I was measuring the SWR in SSB mode through homebrewed SWR meter which doesn’t provide accurate SWR. So the culprit is SWR meter. Thanks, 73
