Sadly the PicoPaddle is no more. Even the website link goes to a dead page.

I voted BNC. I like SMA connectors but the torque requirements are easy to exceed. A BNC is pretty simple

I see your method now. Design a new kit AND a new lab tech. Very smart Congratulations!

Yep, I have a few displays that aren't doing anything. I could take my kit(s) without a display

Hi Jack, You and I are on the same page concerning SMD components. I programmed PLC's for a living for about 25 years (then they put me in manglement and ruined my life :D ) but for some reason Atmel/

When I was almost 59 I decided that it was time to learn to solder SMD's. It made perfect sense to wait that long. I can't see as well as I used to. My hands aren't as steady. But! I am grandkid train

:D I don't have any to check. Perhaps my coffee has gone bad. Or maybe the 950 mile drive that I started at 5PM on Friday and finished at 8AM on Saturday had an effect. The GPS wasn't working. Now it

There's a YT channel (Ben Eater) that I've been watching that ended up pointing me at one of the best programmers I've ever used. It's ridiculously easy to flash a chip. He sells it on his site - http

I literally typed all of that ^^^ walked over to my bench, looked at the current meter on the supply and saw that current was cycling like it normally would. It's working. The 1PPS signal is flashing.

I have an OLG1 that stopped indicating the 1PPS signal. It gave me quite a few years of non-stop service so no complaints. I tested the board today. My hope was that the LM317 had given up (more on th

There's a guy on YT, NA5Y, that built the QCX and 50W amp in stages. He also tested each stage. It was pretty informative and well done https://youtu.be/xo-XD5vB4AA

Very possible. Nothing is where it would normally be because I'm testing. There's a rats nest of power and RF cables. The QCX is working as it should. I'll test the whole setup this evening but clean

:-/ Well, I put the QCX signal into a 50 ohm pass thru terminator then to the scope and the sine wave is gorgeous. 7.020 Mhz, which is exactly the frequency I set. About 2.5W out. No problems at all.

I finally installed a jack in my QCX so I can could the 50W amp and test it all as a package. All of that worked. Just for grins I turned my FT-891 on to see what the QCX sounded like (transmitting in

Thanks George. The test was fast and easy. At 13.8V my old Heathkit wattmeter says 40-ish Watts. Power draw from the PSU was 4.3A (5A is it's limit). I ran it up to 20V but the PSU couldn't keep up. I

OH! That's what I'm missing. Ok, I read that but didn't retain it...

I have my QCX voltage supply set to 13.8VDC. I set the amp supply voltage to 13.8VDC. R5 is fully CCW. SWR meter is a Heathkit HM-2102, 25 or 250W range. I can lower the amp power supply voltage and k

Yes and no. I came up with mine after I bought a Buddipole antenna. I put some posts out about it (don't recall where) but the linked info is far more detailed than I ever posted anywhere. It'll be ha
