Hi Gary, Perhaps there is a problem with your PTT_sense line. The CW options in the SETTINGS menu are only available when the PTT_sense mod is installed. Double-check the PTT-sense wiring and resistor

It seems out of calibration. To be sure follow the hint of using AM broadcasts on shortwave. They are exactly on the frequency they are supposed to be. You can use either LSB or USB and tune exactly

John, Nikos Worked on page px 11 and 0 – not everything is correct but is about 90 percent. ATT and IFS don’t function correctly yet. Could be some others. I will stopped for today. Nikos I

Garbage in, garbage out. And when fabbing PC boards, you really don't want garbage. This world has way to many coffee mug coasters already. . A local software tool such as Gerbv or GerbView will allow

Thanks Alyson!

Another user installed the KD8CEC software and found it to be an improvement. Changing the pull up will not help the issue. The factory code is slow in recognizing keying. Allison

Allison had some good pointers on some first easy fixes to the uBitx in post https://groups.io/g/BITX20/message/57649 First and foremost, either fix the on-board transmit LPF routing somehow or

Due to filtering issues and spurious outputs doing that is not recommended. If you do, familiarize yourself with telecommunications rules that apply to your country. You may not be in

You might find this amusing, but I already did this... and Fiverr responded with the following: Unfortunately, your Gig request "Gerber Files... Convert RS-274D to..." did not pass our review. It was

Gordon, For better than 10W on 80 and at least 7 on 20.... Replace q90 with something better, BFR106 was good. MMBT2369 is ok. Replace the standing 3904s with 2n2222A(to18) part. Hint installing them

I've had some luck with hiring on fiverr.com for totally unrelated small tasks. Might be worth seeing what you can find searching "convert gerber". Contact anyone that has a listing close to what

Hi there, just finished a ubitx build and I am trying to use it with my K3NG arduino keyer. I have set the CW configuration to straight key. The keyer output is open collector. I get a nice sidetone

I've side stepped that. That has been done on every IRF510 amp in Bitx and a big handful more radios out there. In every case my reaction to that is, it is insane. Everyone I see I tell them heat

I still believe "there is a pony out there" .....small handful of parts and a good dual relay switched LPF board. 73 Kees K5BCQ Isn't the rest of that is "I can smell it...." Yes ferrite and a few

Hello everyone I want to amplify the power by amplifier so i want the amplifier for it with simple so i want some suggestions

Yes... but look at how much fun I'll have! Provided someone here can help me figure this out!

Thanks so much Allison --- now that I have a handle on the harmonics, working on Q90 will be one of my next projects. That looked like the easiest gain target.... I have read your posts earlier

Just finished putting the BITx40 in an enclosure and most things are working. I set it up first in the default configuration and tested per directions. I then installed sketch v.1.28 per
