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

Have you tried the radio with headphones? The volume available from the speaker without more amplification is underwhelming. I added one of those cheap $2 amplifiers to increase the volume through the

A 10-50 pF trimmer did the trick. Now pretty close to 5-12Mhz on the upper band. Lost 20M, but still have 40 n 30. Thanks, Curt KB5JO

Ok, since the 560 pF cap isn't in the circuit for the 5-12 MHz scale, assumes this means need to add some capacitance in parallel with the capacitor to bring the top frequency down. QSL the trimmer, b

So the British actually charged people a fee to LISTEN to a radio??!! Wonder how their DF vans would have dealt with a crystal set. Maybe if caught with a 1N34A or Oatmeal box wound with wire in the h

"I believe with the 560 pF capacitor switched in the circuit, to parallel it to c1 (the 365 pF variable tuning capacitor) you are on the higher frequency band, and when c11 is not in parallel with c1,
