"Looking at the picture it appears that you have not attached the switch. Without a discharge path from the common (S meter, AGC voltage) to ground then C6 will remain charged and the attenuating tran

Why, sure!! My computer logging contacts with other computers while I goof off or work. The PC does seem bored and in need of a hobby. -Ted

I've seen the TSW board kit and it looks nice enough. What else do folks here choose from when they're sure their Raduino is toast? Which is the "preferred" sourcing for these ? Please don't recommend

Hello, Konstantin At present, I'm using a 7815 which, provided the solid state components and capacitors have enough margin above them, should be fine. The 510's receive the full battery supply. No pr

A rotary switch for AGC timing/control looks like a smooth idea! Here's a deal for a pair.

The uBitx also runs fine on 15 volts and has a little better sensitivity.... possibly a matter of perception alone due to increased AF gain. Currently running off of a 20 volt Li-Po drill battery and

Here, guys - please try this copy. I don't see a reference to P1 anywhere in the PX page and I don't know how you're seeing one. It's a curiosity, for sure. I'm using the Basic version of this file, a

Ah, yes, to both. If I'd get my cranium out of the other end, it would have been obvious :) I'll have to follow suit. It makes too much sense not to, though edit/exchange/look/edit/repeat is exactly t

Hi, Sam. Please explain what you mean by painted items.... do you mean things like the S-meter path that gets overlaid with the moving meter graphic during operation? What does controlling a decimal v

If it gets to that point, I'll give you a contribution towards your board so I can try to solve another problem or soldier on towards a 3rd radio. -Ted

Which version of that is that, that favors CW use? That's not historically my main mode, but I'm starting to go that direction. Thanks.

Hey, Sam. I exchanged the background photos for the main screen and the frequency manual entry screen(s) for copies that I'd sharpened up a bit with Infranview, and hid the last digit as only a person

Sam, I loaded your earlier afternoon versions and, in the short moments prior to leaving for a HS baseball gave, it looked good. The o-scope graphs are right where they belong :) Great work! Sure, wil

Sam, Thanks! Once I have that in hand, I'll compare the separate functions & accompanying code, maybe learn something. Please do shoot over a copy. I'm sure several of us are grateful. Kelly, It's a s

Anybody have a spare they'd like to part with? The TSW kit is nice enough though handling and soldering deer-tick sized components is a second choice at best. Please advise if so. Thanks. Ted K3RTA

Jerry, Yes, that's the RF preamp. What really happened is that I just wanted a hot receiver, plain and simple. No excuse, no glory, just that I wanted to pick up almost anything on a string of wire fo

A couple of the public libraries around me have 3D printing ability listed as services available at nominal cost. I have yet to try them though I have 2 TFT bezels to obtain sooner or later. You might

This thread has been very educational for those of us who haven't dived into the front ends of a radio nearly as reply as we've done on the output or other RF sections. Thanks, to all. For what it's w

Dexter, You bet it's Cheap-Old-Man compliant, better yet when it originates from a supply that I didn't pay for in the first place. The variation and complexity of so thin a cable makes it ideal......
