@Paul: "Here in europe j310 and 2n2222 are "obsolete"" and "High expedition costs"? First, I think you should ask yourself why you want to have these semiconductors. If you look at the schematic (and

Greetings I also ordered metal can versions of 2n2222 from Mouser at the end of May, to sub on the uBitx. Inexpensive and readily available. 73 Art N9AEP

Whoops, I just saw the prices on mouser. They are horribly expensive. On ebay, chinese sellers are shipping five two dollars.

Vic, Glad you found the problem. ive seen alot of components break down under load,or in other terms under circuit operations. Before i was in engineering i worked as a depot repair tech. working on

David, you win the prize! After confirming continuity right up the the leads of Q911/912, I pulled them from the circuit. Alas, they tested OK on the little transistor checker, so I confirmed that all

Dennis, The display gets its power from the 5volt regulator on the Raduino board.? That is powered from the 12volts through pins 15 and 16 on the main display board. I would verify the in and out

Hi all, Sorry the off-topic. You all probably already know ADX, but just in case: https://antrak.org.tr/blog/adx-arduino-digital-transceiver/ It is very simple, but seems cool for digital modes using

I have traced my no display problem to lack of power. Whap pin or pins on the bottom main board connector supplies power to the display assembly?. Thank Your [email protected]> wrote:

Thank you for everyone who gave me pointers on this. I ended up using just the USB sound dongle without any other interface - could receive happily, but no-one was hearing me, and PSK Reporter wasn't

David, Thanks for the extensive feedback. I am on yet another road trip and I will try out your tips. The calibrate is a very useful tip. - f [email protected]> wrote:
