Can? you provide a link to the software ? Thanks! Mike WA3O

Yes, Mike, the latest CEC software version 1.12 will work fine with your 16 character display. It works pretty nicely, actually. -tedk3rta

All,?? ?I just received My version 5 Ubitx and I wanted to know if there is a modified CEC software for the version 5?? Mine only has the stock LCD NOT the color display. Thanks! Mike WA30

Cool.? Files sent; I'll upgrade later today and give it a run. Tnx Ted

I just installed? the Version 5 into my version 4 case and all went well with no issues! Thanks? Mike WA3O

Bob The 12 MHz crystal filter is quite narrow. If the bfo is way off,? the signal will be highly attenuated by the shape of this filter. Second,? the receiver has less total gsin than some receivers

Curt, are you talking about the stand offs between the screen and the raduino? I will try that tonight. Last night I removed the encoder from Sunil's board. I soldered it straight to the wires

Hi Bob, as Curt already said, the uBitx per se is as sensitive as any other rigs. As many parts of the RX circuits are shared with the TX, if you can a reasonable output power, then you can exclude a

Hi Curt Thanks for the reply. I did think about the wiring of the antenna connector when I was cabling it to the co-ax for the signal generator, it's easy to swap that around. UBITx has a claimed

Hoshnasi What is your uBITX version? What are the symptoms when using the previous calibration values again? What is the calibration value now? (Master Calibration, USB Calibration) (There are

This is audio oscillating. Check your speaker wire carefully. This can happen when the ground wires are mixed up or not connected. The speaker wire must NOT be grounded anywhere. It should go back to

Radio was working fine, however I had a calibration issue so I loaded CEC and connected up MM to set it up.? After getting things set to default for calibration I reset and now I can hear faint noise

There are two tricks : 1. BFR93W in the 45 Mhz IF amps, more overall gain. 2. A 470pf in the emitter degeneration of pre-driver instead of a 0.1uf gives more gain at 28 MHz than 3.5 MHz. - f

Now that ver. 5 schematics has been disclosed, which is the main trick used to get 5W on 10m?

Thank-you Ashhhar! 73 Evan AC9TU

I have updated the circuit descriptions on the website. http://www.hfsignals.com/index.php/ubitx-circuit-description/ There are links to the two previous versions too. - f

Jericho I suspect it's a connection issue between raduino and the main board. Support provided by proper assembly of standoff hardware is important.? I remember having to disassemble mine a few times

Bob There should not be a huge difference in sensitivity.? possibly your bfo setting is out of calibration.? how do ssb signals sound?? make sure you don't have a short across the antenna

Ted, Thank you for your test. If you send a private YouTube video, I can easily find the problem. and Can you send me your uBITX configuration file? (uBITX Manager -> Connect -> Read from uBITX ->

Ian, Tnx agn for your valuable work on this. ?I do notice a problem when on the CW settings (CWL, CWU).? It's almost like the IF is all wrong. almost non-existent reception, and an ear-to-a-tin-can
