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

I've got 3 different LiFePo4 packs. 30A, 15A, and 10A. I have an EFHW antenna, toroid, etc. I just need a way to launch a messenger line over the trees. I may go temporary and use my homemade ground b

Moving is disruptive. Living in two places (one for work, the other is preferred) is worse :) I built a QRPometer (ebay purchase) this weekend and to test it I used my 40m QCX. Yes, I know, an antenna

Back on topic :) The power jack is rated at 5A. I'm not sure what the DC current draw is (yet), I discovered that all of my BNC cabling is 950 miles (1,529 km) away yesterday so testing is on hold unt

I finished my 40m version of the amp this afternoon but I wasn't able to test it. All of my DC plugs are 2.5mm plugs, the amp requires 2.1mm. The correct plug should arrive on Wednesday. I might have

My clock hasn't missed a beat (pun intended :) ) in almost 43,824 hours (tossing in a leap year). Not bad at all :)

I have a Shack clock and GPS module from the first batch. It has been plugged in and running since I built it (not long after it arrived). Other than an occasional rare power failure it's been running

And just for fun, I read the original post again and found another typo, it's supposed to read - I wouldn't ask anyone to disassemble their amp just for this.

I don't have that feature but I do have the ability to read the post before I hit send and not after lol

Thanks Greg, looks like I did it right. One more to go

Good lord... I wish there was a way to edit. My reply above should read: The only photo of the assembled board shows a side view and no details of how the leads are routed. What I would call the top l

The only photo of the assembled board shows a side view and not details of how the leads are routed. What I would call the top leads is pretty straight forward as long as you get the right lead in the

Does anyone have a good photo of how T2 looks when it's installed on the board. I have the leads ohmed out and marked I'm just struggling with how the underside leads traverse under the toroid from th
