Oops, I hope I didn't fail to respond, Joe!.. Sorry if I did. I try very hard to respond to every detail somebody mentions, because I hate it when people don't answer my questions. Essentially, I'll u

Well, well, as BoPeep says in Toy Story, "I've found MY moving buddy!" I'm very glad to have found somebody talk turkey with, Joe, thank you for your extended and detailed response. To go through your

Thank you so very much, Colin :-) I totally agree with all your points, and yes, the absolute primary goal is to save eardrums! Speaking of artifacts, I'm right now working with the clamping release,

Thanks for that input, Roleof, Forward AGC, now that's an interesting idea... Thinking with my fingers on the keyboard.... That would seem like measuring the fraction of the total signal that is actua

So here's another update - and a request for opinions, because I'm doing this for you chaps, and I want to give you something good and useful. This evening I was hammering the unit with CW signals of

Ha! Yes, I remember the 8031. Our other team at the Racine Wisconsin head office was working on a single axis motion controller using that device, if i remember correctly, and it had a full high speed

"BTW your digital AGC sounds neat.. " Thanks :-) Yeah, it has two particular advantages from a user's point of view, one of which you spoke about below; noise: the only noise is from the analog chain

Yes, that seems like a more modern approach, and since I'm planning on using a Teensy anyway, per Jack's (W8TEE) recommendations (and I think he mentioned this filter application too), the whole bloom

Thanks for that link, Jerry, I pulled down the article.

Sorry Art, yes, SCAF. I'm not sure but I think Jerry is thinking about something automatable; we'll have to wait till he elaborates on what he's looking for.

OK, did some research, and now I understand. I'd never had any occasion to use an SCAP before.. So yes, I can generate an accurate 80kHz square wave to drive the switches, but again, we could use an A

Hi Jerry, I've actually thought about the idea of implementing an actual audio filter in the software. One of the later ARMs such is used on the Teensy 4.2 is well able to do that in its sleep. But ge

Hans is, of course, the authority on this, and others may have played with it, but I might be able to be of some help, if you can give me a day or so... As some already know (and this is a good opport

Update Haven't had a lot of time to work on this project recently, but tonight I made some excellent headway. I've got basic limiting working very well, meaning that: a) An audio burst above the thres

Yup, they really are the best bet: I ordered a QCX+30 and an extra encoder for my AGC project on 26th May, the package shipped (paperwork-wise) 1st June, was picked up by the local carrier on 2nd June

Thanks for this summary and the links, Louis. As it happens, last week I finally found enough spare change to order a 30+ to fill the gap between my 20 and 40 classic QCX's, and I look forward to ligh

I had to laugh at what you said about paper factories, Curt. I worked for a Sheboygan, WI company in the paper industry (motion control systems for palletizers, etc., in the finishing rooms) during '8

Buy the dummy load with the QCX and build that first, just to help you remember which end to hold the soldering iron.. I worked for Heathkit in Gloucester, England, back in the mid 70's: I'll bet doll

I gotcher, Steve! I just thought I'd mention the spacer-outer widget because I got bitten by it when I first started learning to use the QCX. I'm certainly nowhere near accomplished enough to send a s

Forgive me if I'm missing something, but isn't the whole point of a keyer that you don't have to do multiple fast taps of the dit paddle yourself? The keyer is there to do it for you. If you insist on
