Hi Jerry, The only function that should really need adjusting is enc_read ( https://github.com/reedbn/ubitxv6/blob/master/encoder.cpp#L110 ). If you revise it to the below, it will be fully linear:

Actually, yes, I can report that putting a 5k ppt in there (or a 10k divider) will drop side tone. Ted

I understand exactly where you're coming from!

All, The CW sidetone is extremely loud. Is it adjustable? Don't think so. It comes out of an Arduino pin and is fed directly into the receive audio chain just before the volume control. OK, is it

Hi Arv: I misunderstood what you were saying for the?clear dumb terminal. Your solution works fine, is easy to code...what's not to like? If the column does come into existence, I hope readers will

Joe: There are a lot of optical encoders that can approach 200 ppr, but they're not cheap. I think I saw one on eBay for less that $30, but that was several weeks ago. Some go as high as several

All, As a first cut toward reasonable tuning, I tried disabling the "momentum" stuff in encoder.cpp. Not too bad. It tunes fairly slow, and is not at all "skittish". But I wouldn't want to scan to the

Hi Jerry, Are you happy with how Reed's firmware works for tuning?? I don't know if the tuning is different on that version or how it works. I have made changes to the tuning myself as I really

Justin, That is the same way that I connected the AGC for my friend's ?BITX.? Was not sure if you did the connection to the board or the volume control. I complain about keyboards and spellcheckers

Jack, That would be very cool. But darn, I’d have to subscribe to CQ. If they go for it let me know and I’ll subscribe. I’ve been wondering about a better encoder. Something like 200 PPR so a

I would be interested in this topic. I put together one that I got a couple of years ago (a v4).

Jack At the risk of giving away some content that may have been better saved for your column, I was talking about the pseudo dumb terminal that is part of the Arduino IDE. To the best of my knowledge

... connected... Man, I hate this laptop keyboard...

Evan, The AGC board I installed is at this link which shows how it is conjnected to the uBITX PCB. https://shop.kit-projects.com/index.php?route=product/product&product_id=101 73, Justin B. KI5GKD

Hi Arv: All of those would be interesting, but I don't know anything about BitLash other than what it is. Usually, a device being used as a screen (e.g., 16x2 display or TFT color display) will have

https://app.designfast.com/search?q=lm7805&page=1 Might help _._

All, So the reason I wanted to upload sketches is as follows: I find the tuning of the uBITX troublesome. Say I'm at the top of 40M and I want to get down to the CW segment: I spin the knob, and down

Jack Of course I would be interested. I might even be able to contribute some problems and maybe some solutions for the column. Things that immediately come to mind: - How to do a Screen Clear on the

Hello, I’ve read a lot about the isolation of analog and digital masses and their star connection. For me and for the digital masses, I see at least 4. The arduino, the SI535, the Nextion and the

Woo hoo! It worked! I also changed the code a bit - added an extra printout just to convince me that it had actually uploaded. I was fooled because the IDE didn't display anything like "upload
