Hi John, Condolences and/or congratulations for the opportunity! Earlier docs from Farhan says the core is an FT37-43. The calculator at kits and parts says it should be 13.1 turns for 60 µH. http://t

Aaron, Sorry to hear about pain meds - pain's no fun. I hope it's temporary. W0EB has a BCB filter, for one example: http://www.w0eb.com/ 72/73, Andy, KG5RKP

Another firmware option is from TSW. It's actually a firmware and hardware option, as using the firmware requires replacing the Arduino Nano with a small adapter board and a Teensy 4.0. This is a sign

Thanks Ole. I did the survey on my Windows desktop using Chrome. I got to the end of the survey where it said I'd be directed back to the ARRL for the coupon, and instead was handed another random sur

Took the survey; didn't receive a coupon. Can only try once. Thanks anyway, Doug. 73, Andy

Since the list of Nobel winners is public, I'll take "Who owns a µBITX" for $100, Alex. https://www.nobelprize.org/prizes/lists/all-nobel-prizes/

Stephen, This is a problem with V2.2.2 of WSJT-X (possibly related to Hamlib 4.0) and I had the same challenge with my µBITX. I dropped back to V2.2.0 and FT-817 control works perfectly. As an alterna

Sorry for the dupe...covered in another thread.

Pete, N6QW's got your covered: http://bitxhacks.blogspot.com/2017/12/adding-external-linear-amplifier.html 73, Andy, KG5RKP

I had the same problem last night when I upgraded WSJT-X to the current V2.2.2. I dropped back to 2.2.0 and FT817 works fine. With V2.2.2, changing to FT-857 is reported to work. https://wsjtx.groups.

I appreciate your time, Allison. I also feel silly as I ordered NOS 2N2222A from Dan's Small Parts a month or three back. They're still $0.50 each plus a bit of shipping. I've been trying to collect p

I'd love to hear from anyone that can advise either where/how to acquire good quality 2N2222A, or 2N5109, of 2N3866 for a decent price. Mouser has 2N2222A in stock, but the least expensive are now $4.

Peter, I'm using a V3 with CAT. As others have said, the USB connection is the one on the Arduino Nano. I'm using the KD8CEC firmware. It works great with WSJT-X and Winlink/Winmoor. I'm using this ca

TX: 40/20 (antenna limited) RX: all over the place!

Jack (KZ5A), I don't think the circuit changed, only the size of the board. There's a link to free docs here: https://groups.io/g/BITX20/topic/free_gerber_files_for_sound/19351002?p=,,,20,0,0,0::recen

Doc, I've used these utilities to scan the bus for existing addresses. Good tools to have in the drawer. https://create.arduino.cc/projecthub/abdularbi17/how-to-scan-i2c-address-in-arduino-eaadda http

Hi Rubens, The first part of this document has instructions for setting PA bias: http://ubitx.net/wp-content/uploads/2018/06/uBITX-tune-up-instructions.pdf 73, Andy, KG5RKP

Hi Barry, Thanks for sharing your experience. I'll start a search for something mechanical! 73, Andy

Thanks Curt! I see what you mean about touch-specific 'keyer interfaces'. I explored the capabilities of the BITX and µBITX but neglected to consider a more 'universal' connection. I had to apologize

Folks, I'm continuing to stuff CW into my brain and hope to be able to operate at some point in the not too distant future. Until then, I'm trying to wrap my mind around keyers. I have a decent straig
