What Kit's would be nice for 2021
I like the idea of the tube based xcvr. I've never built one, though I do have an FT-101 upstairs that I want to recap, retube, and neutralize. There's something wonky in the thing...when it has been

How do I get to the 4sqrp Store?
4SQRP does not control the structure of that menu, except by enabling or disabling features. A store link is not a feature they can enable, as they neither created nor control Groups.io. That is a thi

Ozark Patrol Audio Transformer and Jack
One thing that might be affecting regeneration is the "gimmick" capacitor C12. You might need more twists or fewer twists. I found it really changes the regeneration level a LOT. -=-=-=-=-=-=-=-=- 73,

Ozark Patrol Tuning adjustment question
Perhaps our British members might be able to verify if this is how the BBC's roving radio detection vans would locate people who hadn't paid their radio license fees? I've seen pictures of these vans,

It's interesting that you mention W3EDP antennas, Joshua. I have one as my main wire on my home station right now. I love the design, and it seems to work really well for me. I haven't used one portab

Is the 4SQRP Ozark Patrol QSO worthy?
Don, I haven't tried using my Ozark Patrol with a separate TX because a) I didn't think of that, and b) I don't have a separate TX that isn't also an RX! Maybe I'll try it if I build the Michigan Migh
