Jim, Thanks for the fine work! You ought to publish this in QST, with a little subtle advertising about the Jumper and why every ham needs one. I have been doing my part, managed to sell two ops on ho

I just connect ozark patrol ground to station ground, which in my case is also electrical safety ground. Like everything else in the shack lol Curt KB5JO

Well, that is my observation too. And yes the FT8 n FT4, etc has activity when no CW heard here. In fact, I kinda use the FT8 segment to see if a band is active or not. I must confess, don't get much

You are way braver than me. I grew up about 40 miles east of there, ( first call WN6HJZ ) and that park was a zoo 50+ years ago. Full of druggies and everything else person could imagine. My future wi

Cycle 25 is evidently underway, but for me so far the results have been pretty mediocre. Using a variety of radios ( BJ40, 5W-30, HT-20, K1 ) on 20,30,40 using wire antennas, have yet to get beyond th

the suffix after @ is cut off. I just looked up banner on the 4SQRP web site and sent submission to address for editor which was editorqrpbanner at gmail.com It cut it off on my original message too l

FWIW, mine has a most definite regeneration point. So if yours isn't that isn't normal. Curt KB5JO

You can check if the transistor is fubar using dvm on diode. Curt KB5JO

Sometimes regeneration doesn't work because the sense of the coil wilndings is wrong. Be sure the coil looks line the one in the assembly drawing. There aren't many parts in the regeneration circuit.

You could easily unsolder Q3 and test it with your DVM on diode test. I bought 5 minimodule LM386 amps for $10 delivered. No constuction just hook them up. GL n 73, Curt KB5JO

Maybe not relevant: The stock radio doesn't put out much volume into the speaker. Headphones worked fine, I bought a $2 audio amp and wired it into the speaker circuit, now volume from the speaker is

A few years ago was wanting to build a Paraset replica, thankfully the Bayou Jumper came along and scratched the itch without having to build the hardware needed for a replica. The Jumper is a fun, we

This interests me, although don't own a KX2. My K1-4 has 15, 20, 30, and 40M. It also has a KAT1 internal tuner. I usually use a SOTA tuner to load a 34' wire in a tree with the internal tuner disable

Worked 16 stations over 2 hours operating CW on 15, 20, 40 from the patio table using a K1-4 into a wire thrown into a pine tree. Attached is a picture of the setup. Ignore the clutter please lol. I q

Herb, Happy you found the problem. Assume that it was solder at R3 or at the regen and not a broken land on the board. Almost every problem have had with a kit has been a missing or poor soldered conn

Herb, Wonderful! glad you have found the problem, you will have a lot of fun with the radio, I sure enjoy mine. 73, Curt KB5JO

Just for info, my radio (which works) has following readings Curt KB5JO

Herb No voltage on Q1 base implies short to ground in that circuit. Absent an internal B-E short, the voltage should be at least 1/2V across D2 and D3. Since you have replaced that transistor, the oth

Herb, Any progress getting the radio to function? Curt KB5JO

"I even removed L1 and reversed it" Be sure to put the toroid back as shown in the build manual. If the "sense" for the one-turn tickler is wrong the regeneration won't. So trying to correct low volum
