Dennis Petersen: Nice review and too bad it's not offered in kit form anymore. Thanks and 73s
incubusman421: Does anybody make BFOs these days? I know Ten-Tec stopped making the kits.
DoomsdayDarin: The full details of the Ten Tec 1050 kit can be found in the Nov 2000 (11-2000) issue of 73 Amateur Radio Today magazine pages 22 and 23. This magazine can be viewed for free on the Internet Archive website.
leiderwanwer reises: ola amigo gostei muito do seu oscilador .....BFO vc poderia me mandar os esquemas te agradeço firstname.lastname@example.org...............email@example.com
NG9D: Amigo. O transístor usado neste circuito é NPN TT25054 (substituto para MPS6514). 73 Lynn NG9D
Wander Lucio Gomes: Amigo. Qual é o Transistor utilizado nesse circuito?
NG9D: Olá, você pode encontrar usando imagens do Google de busca palavras-chave: (You can find schematic using Google image search using key words) 455 khz bfo schematic ten tec

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

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.
F4EPU: Nice realisation!

Radionut R: How does it hook up to the radio? Unclear BUT looks like fun!!!
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.
NG9D: Vielen Dank

Vet: When I graduated High School, all I wanted to do was kick back and relax without having to do any homework. But I realized I have no money to do anything fun. So I went to a San Francisco Vet School to get trained to make money. But seeing your videos, I am gonna be an internet marketer on the side. Let me know if you have any tips. Thanks.
