I don't want to submit a photo.

Are you using a linear power supply or a switching supply I tried a computer power supply on my bitx40 and had a much more noise than with the linear supply or batteries.

Did you notice any smoke or fireworks around the vicinity of the TDA2822?? Use a magnifier to examine the chip - any cracks or burned places?? If not attach a speaker directly to pins 7 and 8 of the

@Arv K7HKL - Thanks for your input, but I really do not want to re-invent the wheel. I was more looking for somebody who has done it, and could tell me what parts are needed. In that regard, I found a

This has to do with the SI5351 library. Upgrade the software to Allard's version and the issue should go away. A lot of work was put into the software to resolve this and many

@Dexter N Muir<mailto:dexy@...> No! That ticking when changing the frequency is present but not invasive! This is just annoying! Try watching the video! Thank you

Yes - i agree - Dupont jumpers are meant for hacking. Good to make a point then make permanent. To this day my BITX40 as pictured is still in use on plywood breadboard. ? Works fine, last long

Nicks boards are excellent, I have one myself. Well worth getting as an upgrade or replacement. Cheers Adrian

Hi Gents. You? can build a new one easily. See my blog : VK4PLN.blogspot.com.au... I have a blank PCB that is easy to build and allowes other upgrades later too... 73

No worries, Alan. Do you have my email address? It's good on QRZ.com. Or go to my web site ND6T.com ( http://www.nd6t.com ) and get it there. The graphics on my site blow up big and easy to read (just

Hi tom. Great build. A tip on your vol knob, just elongated the hole in the direction you want to move to knob, you can go a fair bit as the knob it self will hide the extra hole so to speak... 73

Hello Alan, What gets me is the higher than expected voltage you get. It it was just not reporting the proper balance of values it could just be a winding direction but I think there is more. Just

Congrats. BUT DON'T JUST PLUG POWER AND LET THE T6DA BURN FOR NO REASON. FOLLOW THE RECENT DISCUSSION VU2ZAP SUGGESTED A REGULATOR 7808 FOR FEEDING POWER TO tda2822 ALONE. AFTER THAT YOU CAN SAFEGUARD
