BFO Kit For SSB / CW Shortwave Radios




What do you think about this video?

WX9DX: I have built and installed these Ten Tec BFO kits in lots of AM only radios. Even into CB radios so they could hear sideband. The other cool thing they make a neat kit for people learning electronics to get used to soldering and alignment etc. Lots of cool theory for them to learn in building this kit. Thanks Jimmy, ARRL TC, WX9DX

dani grg: hello ...wow.. nice... please send me circuit diagram..

Glaiza Heyrosa: hi friend, can u send a bfo circuit diagram. reply. tks.

sparkdetect: I built one of these...I had to re-tune the ferrite slug often as I tuned across a ham band, and worse, the drift was unacceptable; I had to constantly adjust the tuning knob. Would be nice if they brought out a new kit with better stability.

timeanagain: Are special tools needed for this kit build? Could a beginner build it? I passed the Novice license exam about 25 years ago, but never got started in Ham radio. Would love to practice receiving morse code again. I can't seem to find and inexpensive radio with BFO on it. Any suggestions for that route? Thanks

Radionut R: How does it hook up to the radio? Unclear BUT looks like fun!!!

Marco Hofschneider: What about the zillions or older radios out there that use an IF of 460 khz, like the vintage Grundigs for example?

F4EPU: Nice realisation! 73s David F4EPU

Chris Freitas: Wow! That receiver brings back fond memories. Aside from an old Sears multiband I got from a friend, the RadioShack DX-397 was my very first shortwave radio. On my 15th birthday, my Dad and a family friend took me to my hometown's RadioShack and picked it up for $40. I loved that radio. Unfortunately, it wasn't able to pick up many stations over the years, but it was great when it worked. My dad still has that radio along with a Grundig Mini World 300 that I gave him 3 years ago.

Wander Lucio Gomes: Amigo. Qual é o Transistor utilizado nesse circuito?

A Ebel: How do you connect this to a short wave boombox? By the antenna input? Or do I have to go inside the connect it IF AM output connection?

timeanagain: Thanks for the info. Ordered the kit and will give it a go.

NG9D: For great CW practice I think the TenTec T1056 Receiver Kit would be ideal. I am making one now for 40m -- in my opinion, 40 m is one of the most reliable bands for CW/Morse code reception. I have made T1056 boards for 20 and 160m, and they both work great! A 25W soldering iron, diagonal cutters, small screwdriver and needle nose pliers are about the only tools needed to build the receiver kit. Practicing CW on a radio you made yourself is a lot of fun! 73 de NG9D . .

NG9D: Vielen Dank Radio macht Spaß 73 de Lynn NG9D

leiderwanwer reises: ei amigo vc me mandaria esse esquema OFB te agradeço ficou muito bom wanderleyreis713@hotmail.com

Shortwave68: Very interesting video! Good job! Greetings from Germany!!

A Ebel: I got this kit, but cannot get it demodulate SSB signals, because the transistor that came with the kit went missing. I used a PN2222A NPN transistor and it's oscillating, but it's tuning narrow. Do I need to use the required transistor called the 2N4124? The radio I am using is the S450DLX with a 455 kHz output jack.

NG9D: OH2FFY DE NG9D Hi Greg, I had to *edit* that part to keep my video "politically correct" ;-) 73 Lynn NG9D . .

NG9D: Amigo. O transístor usado neste circuito é NPN TT25054 (substituto para MPS6514). 73 Lynn NG9D
