A drop or 2 of hot glue should not make too much difference. -- Mike VK3XL

Mine were glued down. S

My BITX40 arrived in good nick - but I wonder If I can make the board more drop proof. Is it possible to stick the toroids to the board with hot glue or epoxy? Or does that mess up the

Hi folks … I received my BITX40 today (my 3rd) and found that L1 had been torn loose from the board. It was rattling around in the plastic box. After examining the way the board, Raduino, and

I built this up today and it made a world of difference. I used a 470K and installed R4 in case I want to add the side tone later. Thanks! Jeff N9ARZ

If you are looking for BitX40 QSOs at any time you can go to this site http://www.dxsummit.fi/#/?include=7MHz&qrp=true and list your frequency and call and "BitX40"or look for other BitX users who

Hi all, I have 2 BitX40s one on 40 meters and the other on 80 meters.Both are working ok, but I have plans to convert one of them to multi band operation. The hardware modification of the BitX40 board

The function button needed for the new Raduino software is connected to the orange wire on the Raduino 8 pin connector. It is wired so as to momentarily connect it to the Raduino circuit ground.

Almost any Arduino tutorial will tell you how to use the IDE and program one of the Arduino chips. Not sure which buttons you are referring to. Jack, W8TEE To: [email protected] Sent: Monday, May

... Well that was a great first start. Hopefully, we can encourage a few more to try and join us next time Monday night. I think we might need to try and find a better frequency - as Allard noted we

Farhan, Maybe a stretch maybe not. ;) ?I agree with you, EMRFD is the basis for an awful lot of the interesting designs. I am wondering, though, what books you would recommend as texts to dig into

Congrats Luke! Hopefully I'll have more luck next time. Good to hear that v1.09 works well for you. 73, Allard PE1NWL

The latest version can be downloaded from https://github.com/amunters/bitx40 See the README document at https://github.com/amunters/bitx40/blob/master/README.md The user instructions are

Allard, Has a nice qso with Mike G4KXQ, all of that using V1.09 :) Thanks 73's Luke ON2AAV

any writeups on how to flash new firmware and add the function button(s?)? also what do they do?

Heard Adi YO2LIW about 53, and also heard G4KXQ (about 55) calling Luke AN2AAV. Didn't hear Luke himself. But I had strong QRM from an Italian station at only 1kHz up, and image carrier from a

Adi, Great thanks for the RX report of my sig. Let's hope for less QRM and QSB next time ;) 73's ON2AAV Luke

I also copied you for short time, Luc (tried to call you). Carl, M0ICR was about 55 to me but with deep QSB (tnx QSO Carl). A surprise was UA9CAW with good signal (54 received). Boris was using a

Seth, It would be a stretch to place me anywhere in the pantheon. I am a regular guy who has had lots of time. The real hero of our decade is actually a book : the experimental methods in RF Design.
