Jerry, If you have been reading I've mentioned I have several amps that actually do work... Bag, cat, QSX amp. I've been beating the crap out of one and its by far one of the most solid designs to

Jim, >>one other thing on the Elecraft T1 autotuner. I remember something that Wayne Burdick, N6KR (Elecraft founder and CEO) said about the T1. During initial testing of it, he messed up and

Joop, IF you don't mind grinding code where are many possible fixes. I would suggest looking at V4.3 as it is a bit cleaner and more current. The biggest issue is the software is a big loop and CW ke

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

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

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 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.

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

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

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:

They are marginal at best... save your Money and get a better tuner... -- 72 and God bless KD4EPG

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

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

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

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
