#5 Valve QRP - Building a Paraset
Вставка
- Опубліковано 12 бер 2017
- The scratch build of a customised Paraset Spy Radio in just a few simple steps from schematic to completion. The 6V6 delivers +36dBm (4W) into a conventional 50 Ohm antenna and the lively regenerative receiver handled its first QSO with Hub, F5JYS who was running a K2 at 5W on a very noisy, crowded band. Great fun!
Thank you, Graham (Silent Key), for your helpful tips building the Paraset all those years ago. You motivated me to build my own! . .
Graham, beautiful video! I built mine about 12 years ago and have enjoyed using it. My best QSO was on 80M 3505 kHz across the pond to Germany with it which was on a random CQ. But the German ham was actually a WW2 Wehrmacht radio van man who hunted these! He sent a and QSL. My only changes were bandspreading. WU2D
I realise this video is a few years old, but its quite frankly outstanding, your attention to detail and quality is remarkable, i had a qso this evening with a G4 station running a paraset on 40m........an easy qso between France and the UK ! Thankyou.
Excellent video as I was an interceptor in the Army Signal I found this information extremely interesting.
Nice! I really like the idea of the paraset, and its history... I hope to build one as well. 73!
Graham, many thanks for your invaluable help and advice when I built mine, looking forward to a Paraset to Paraset QSO in the future
Great job, Graham. Really enjoyed your presentation and great workmanship on your paraset! What a neat rig you turned out. The hanks for sharing. I'm one of those who built the American transistorized version of the Bayou Jumper. Enjoy using it. Looking forward to your next video/project. 73's de Rick, W B 3 B I Q.
Beautiful valve rig! I built the transistorized 4SQRP Group Bayou Jumper kit. Fantastic little rig with a switchable built in 200Hz CW filter, added mute receive during transmit, fine tuning control and side tone generator.
That's a good job Graham, it looks very nice. It puts fun into radio instead of operating a fancy bought set all the time. I love building stuff. I built a transmitter using a 61BT valve I had, for 5.262 MHz, 7.030 MHz and 10.106 MHz.
Thanks Graham for sharing your Parset with us. I have most of the parts for mine just need to order the caps, resistors, etc. and the transmit/receiver switch. I did build the solid state kit that you speak of and it is called the Bayou Jumper. Great little kit and it has given me hours of fun already. Very much interested in the SOE and the Paraset radio. Once again many Thanks for sharing.
Hi, really nice job Graham! I enjoyed watching your video of this project. The video happened to come up in my recommended by youtube list, quite timely too as I've almost finished reading the book "The Secret Wireless War" written by Geoffrey Pidgeon, who worked in the workshops building sets.
Graham, thank you for this very interesting video!
Most excellent. Top shelf. Thank you Sir for sharing.
Hi Graham, nice job! An idea for a future video: a whistle stop tour of you lab and test equipment, some of it looks very interesting! De VK4QP
Incredible good job! 73s de Stephan DF6PA
Thanks for posting this video.
I'm not sure why they used 6SK7 tubes (valves). These were supercontrol or remote cutoff types. Usually the sharp cutoff 6SJ7 would have been used as a detector and audio amplifier. Perhaps at the time the 6SK7 was easier to source. If building a replica, I'd try both types and see which worked better. Also the type 6AG7 power pentode could be used in the transmitter instead of the type 6V6. I have a few of those and none of the 6V6 metal types in my junk box.
Where can i find the schema and the list of components please ? I'd like to build one...
thanks for the video. I am just embarking on a Paraset project myself. I note that you dont offer any build plans etc but would you be willing to make your parts list available? Matt
Hi - be interested to know where they got 360v dc working in the field - Graham M0GTC
