No explanation is needed although appreciated I am sure. Your assistance in trouble shooting here and actual repair at home goes way above and beyond. I know those who have benefitted from your help

George, you can substitute any PNP with at least the same voltage rating. I used one in a small power package on the reverse side of the board in my original QCX.

Hello Everybody, I just found one of the newest Alan's W2AEW youtube video. This time was about installing the new AGC kit on the QCX. As usual, well documented and very valuable for self

Based on my experience with v1 I would wind all the toroids first. That way once you start soldering parts in place you don't have long breaks as you wind and install each toroid. dave k2lyv

I have a couple of outstanding repair/build project for my friends here, so rather than address each one individually, and in the interests of transparency, here's a general status note: I've just

I'm kind of feeling like a QRP signal wouldn't even make it to the radiating elements on that antenna... :-) Doug, W0UHU

Thanks Ryan for the post as I have been busy the last few days and haven't had a chance to respond to the group. As Ryan mentioned it was a simple build error in that I missed soldering a connection

From my good old (vodoo) days of NF Amp building I still have an "overcomplete" stock of BS170 (^_*) Among them I do own a couple of QUAD sets (4T with identical Spec). All those BS170 have spent a

Hi All, Anyone who has a DigiKey or Mouser part number for the MPS 751. In WSPR or Beacon it seems to be hotter than the BS 170's and I would like spares. Hans, thank you. Thanks, George

Paul, you’ve brought up something intriguing and that may appear on iPhones in the next few years. Apple, normally extremely secretive about new developments, has been hinting that it is working on

"The simple tee-network does not serve one of the main purposes of the antenna tuner:circuit. harmonic reduction."

As a card-carrying EFHW cult member, there are benefits in addition to being multiband. They are relatively easy to build and put up, feedlines can be short, and they are inexpensive. Are there

Great to hear Paul, glad it made it to you safely and fast! Rich KQ9L

It's not always possible to hang a dipole and run the feed line. If your shack is in a corner of your property lot it may be impossible without running a long feed line parallel to the

I use MyAntenna 80-10M EFHW as my only antenna, not because of site restrictions, but because of XYL restrictions. (Really sad, as we're on almost 3 acres of dirt.) For me, a dipole would have been

I believe this Fair-Rite toroid is the ft240-43 ... it has the same number as the Fair-Rite core in your illustration. I got some a while back from Newark and they were like 6 dollars or so each. They

Build one and try it and then report back on how lousy it is. It is all I use at my QTH with 5w CW (since 2016) and the EU is no problem or the four corners of the US either. I usually use 200mw
