Thanks Joe and Michael, Ed Kelley 828 Althauser St. Dubuque, IA 52001 PS send me your PayPal email. Thanks Ed

Ok, update: ?Michael has decided to pass, so Ed looks like you’re next in line. Just let me know where to send it.

First: I take it the empty pads etc have markings? D an VR numbers? If so, they're most likely superseded by? a 'double-diode package. The original diodes were iN4148(equivalent)s and the trimpot was

Have you worked out pricing for the Lotsa Clock pcb Mike and how did your DX mail weighing of the 2 pcb offer go? Bill, VK7MX

Boy that was fast ?. Ok Michael, you asked first so I guess you win. Just let me know where to send it.

If you don’t have somebody already, I’m learning a lot about electronics and I would love to have a 20m kit to play around with. Would be fun to fix too. Thanks, Ben KD2NOU Ben KD2NOU

I can PayPal you say 20 to cover shipping Ed W0IC

I have a Hendricks Bitx17A kit and I would like a 20 to fix Ed W0OIC ekelley828 at centurylink.net

If you haven't had a taker I'll go for it.? ?I have some equipment that I can troubleshoot with.? 73, MichaElKM4OLT Sent from Yahoo Mail on Android

Hello, I built a Hendricks Bitx20A kit a few years ago.? It actually worked for a bit, had one QSO, but I never got it to work consistently.? Oscillation in the PA, and now I may have added a new

C93, C103, R106 are not stuffed, and are not needed. The board is stuffed with MMBT3904's, not BC849's. ?I doubt swapping the MMBT3904's out would improve anything. Haven't heard many complaints

Hello, I have purchased 3 Bitx 40s v3 and I'm totally new to this transceiver so I have a couple of questions about the PCB and the Transistors. First question is what are the empty pads a trimmer

Hello Paul: Well, yes, I used Si5351, since I am following Farhan's instructions as best I can. Basically, my set corresponds to the idea of Farhan, except in the control, since I am using an Arduino

Been a while since anyone asked about a 20a. Take a look at http://golddredgervideo.com/kc0wox/bitxkitsigtrace/txscope.htm It sounds like you have all you need to intelligently troubleshoot it.

OK I am reviving my very old thread, because without getting it working, I put it aside -- for a few years! ?Now trying again. It is a Bitx20A kit from Hendricks, built but never worked right for

On mine I used an inverter for RTS so it would work with my IC-706, and then when I went to connect it to my bitx40 (with the EASY-DIGI interface too) it wouldn't key PTT for me, so I used Allard's CW

Do it after the opto? Just an inverter. Amazing, I wonder how they figured out all the simulation stuff at Circuit Lab. Others were built on the SPICE stuff done and released because it was funded by

Yea, I guess the optocoupler doesn't need a full 5V to close the PTT circuit. I'll try it without R1 and see what happens. This editor is Circuit Lab, which is a *fantastic* editor and simulator, but

That 1K in the emitter cuts your signal in half?? With Q1 fully on, D1 gets 1/2 of Vcc (5V).? So your output on D1 is less than 2V. I like you schematic editor, what is it? Mike, WA6ISP -- Mike

Ok, got things working! All that was missing was a diode from the Collector.? Here's my final circuit:? PTT toggles on and off from WSJT-X as expected :) Thanks for all the help!
