Kee's Are you talking filters at the output of the rig, for use with current v3 and v4 boards? That's likely the best bet for getting current rigs compliant. Me, I'm ok with dropping the high bands,

Okay! Sounds good, will have a look. I’m afraid the stock firmware is unusable for serious CW transmissions. Thanks, Joop PG4I

Thanks Allison, I have now tried both the recent V4.3 from GitHub and KD8CEC’s version. Ian’s version works a bit better, attack time is improved but I am still missing part of the first dit to

Makes more sense in this thread............. Since most keep talking about the need for BPFs for certain bands, I "guess" the 80m-10m uBITX direction should be a board with 6 filter capability. How

Answer. The comment means- apparently someone is successful in the realm of electronics and ham radio. Another coincidental BITX success? It is simply newsworthy and I wish him well. Just like when

Sean, Its been several days since you posted likely its eben seens and everyone is going "I dunno". Not enough description of whats going on or not going on. Not sure of the mods done. Are

Jerry KE7ER, >>I'll be buying that amp, once Hans starts selling it.. Then cut off the back half of my uBitx with a hacksaw. And you have half a radio.... That amp expect about 12-14dbm drive from

Dennis Yancey #58339 They are marginal at best... save your Money and get a better tuner... What is marginal at best? Does it have a name or ? Allison

Timothy, Have you ever looked at the board? Fixing the driver moved the problem sage back to the predriver and first amp. Pulling bands at the time of its design was not considered as it was desired

If it is done cleanly it could look quite nice. Specifically small copper lugs can be soldered on the bottoms of the existing control relay pins to attach to braided core Cu wires which are then hot

Yes, it would be a lot easier to simply disable the LPF's and use external filters. As per the final sentence here from long ago, keeps things very simple:

My thinking is that this whole discussion of butchering the uBITx board and cobbling in another board that, in itself, will have some sensitivities to things like cable runs and connections etc. will

The flaming obvious and yet trivial has just occurred. How are people going to mount the PCB as shown ? Three hole posns at a minimum will be required for say 3.4mm holes. Edge distances have to

I dust did. An interesting article with lots of good information. http://sp-hm.pl/attachment.php?aid=413 Tom, wb6b

He is getting a laser cut acrylic version. I offered to print a few if he provided the material to produce the object . Instead they went with laser cut acrylic. Ill get s copy of that object in case

I am sure I missed this topic, but my keyer worked fine until I upgraded the firmware to KD8CEC's V. 1.095 for use with my 4.3-inch Nextion display. Since the upgrade, I can only use a straight key.

On w0eb.com webpage is NANO software that implements interrupt driven CW generation. Also eliminates the voltage divider scheme. Also eliminates the need to switch between straight key and paddle

I'm convinced Hans did a good job. Especially after seeing this in his post: "I am very grateful to Allison KB1GMX for her advice, encouragement, support and testing during the development of this

Jerry KE7ER, The key to make it fly is layout to avoid ground loops and parasitics and attention to cooling and that includes the BS170s. There are pictures of his board. and for that fact the
