I found that a generic 2N2222 worked identically well to the Q1 transistor originally in this receiver. Try that, if you have one handy. On a slightly different related topic, has anyone ever tried

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

Curt, I checked the coil sense---ok. I even removed the coil and rechecked the tinned ends and replaced the secondary "winding". Dave Cripe suggested privately that I should just rebuild the entire

Gwen, I replaced the gimmick cap with a variable cap and fixed cap in series to give me about 0-5pf. -- Dale Hardin, KS4NS Elberta, AL

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

Nice idea, Paul! 73- Dave, K1SWL

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

Greetings! I built my Hilltopper 40 way back when, and built in an additional feature. The rig has no power switch, so I added a “power on” LED. That way I won’t forget to disconnect power to

The Bayou Jumper is SOLD and on it's way to the new owner. Thanks to everyone for the many responses. Bob Groh, WA2CKY

Thanks Johnny. I think he is already following this incident. BTW, this is the rig that a previous ham gave up on in frustration. You might remember his posts. I decided to take on the

Gm Dale See if you can get in touch with Dave Cripe, NM0S. His email is NM0S@... He designed this little bugger, I bet he can get you kick started. It might be best to email him direct. Be patient, he

I ran the troubleshooting voltages in the Assembly Manual. The battery voltage iws 8.434v. The following voltages are in list order: 0.000 0.889 7.849 0.615 3.454 2.772 4.815 Looks like the voltages

OK, got the little amp installed and working. After replacing all the transistors, I hooked up my signal injector to the antenna end and got a tone out of the speaker. However, I do not have any

K0B "BRUTUS BASH" SPECIAL OPERATING EVENT When: Wednesday, 9 September 2020 18:00 to Sunday, 13 September 2020 12:00 (UTC-05:00) America/Chicago Repeats: Daily, through Sunday, 13 September

Hi Jim That was a good book. Jim I got a call from a fellow ham that I placed first in the Delta Division in the International SSS Contest as QRP Single operator. I MUST HAVE BEEN THE ONLY Entry. HI

From Steve Hartley - chairman of the G-QRP Club Folks I am just out of this week's progress meeting for the Convention and all is on track for it to be a great weekend of live QRP talks with Q&A

HELLO BOB; IF YOU STILL HAVE THE BJ - I'D LIKIE TO CHAT WITH U ABT IT 47/73 - SKIP "If you are able to read this, thank a teacher; while it is still in English, thank a veteran!" May God bless -

Cleaning up the ham shack a bit and, after looking at all the rigs I have to work on, decided to put my Bayou Jumper up for sale. Never built - I believe I got it at the 2107 Convention and just have

Nice to know about the 7100-7125 segment. Kind of where I will wind up when I get back on. Someday. Bob, WA2CKY

Another for your fireside reading - quite a few references to ham operators helping in 1940s electronics development: It's a story of the development of the proximity fuse: 12 Seconds of Silence by
