Re: BITX40 First version (Through hole type) - Wiring Up diagram required
Really, the large size (1206) SMD parts are not that bad to use even for a pair of 76 year old eyes, plus resistors and caps are really much less expensive than through-hole. You could also shrink the board size a bit, since Farhan made it oversized to allow for experimenting. If the Gerbers could be edited, I think there would be some interest in the board.

With the Bitx radios you would have to get just a little creative to trigger the TX/RX relay but that shouldn't be very difficult.

Re: Flrig and uBitX not connecting
Update: I did download and update the driver to CH340, but that made no difference. Memory Manager still works, but Flrig does not.
However, i loaded WSJT-X and set it for the same COM port and as an FT817 and it controls and reads the rig fine, so the problem is only with Flrig.

Re: Inexpensive eBay Amplifier Kits
Since it's not a kit, it's subject to FCC certification. Is the amp certified?

Re: Dave West --PLEASE DELETE
Quel est le rapport avec l'uBitx ? Olivier.
I don't require an apology, so not accepted. Was nothing wrong with the photo that I saw. Accidents happen. Like my HP laptop keyboard. If I begin typing too fast and pressing the keys too hard windows begin popping open or weird characters begin showing on the screen that I didn't type. I need to stop talking about this lousy laptop and transfer everything to my other laptop, a Dell Latitude. Nice looking Gent. Wish I could say the same for me. I look in the mirror every morning... ugh. Terry - KB8AMZ Brimfield Twp, OH USA EN91hd Linux User# 412308, Ubuntu User# 34905,?PCARS#78, NAQCC#6668, QRP-ARCI#8855, SKCC#14195
Yes! I was emailing a photo of my great-grandfather to a nephew,
and my email program said it sent the photo to this group, too! I
don't know what happened, but I'm glad it didn't show up here.

Hi everyone. Thanks for the interest. I will put all of you that have responded and emailed me at the top of the list... I will try to get this done ASAP, but I have very little time lately with work and life, but I will try... The design is mostly done, but I want to do this one with some decent documentation, and schematics too. Thanks again. 73 Nick VK4PP

Hello ! Maybe there :? Regards ! Olivier.
Do you happen to have a source/part number for the heat sink?

What kind of antenna are you using? My own experience was that with a long-wire antenna there was lots of BC interference. (I am about 10 km from an AM broadcast transmitter site, with more of them slightly further away). When I switched to using a dipole for 40 m or my multi-band tuned vertical, all the broadcast interference disappeared.
