The Bruce Kelly 1929 QSO Party is a two weekend CW contest using homebrew Retro Design Transmitters from the 1920s. Take a look at this Type 211 Tube Hartley Oscillator for 160 Meters.
Fantastic Mike and has to be one of the finest examples of homebrew vintage Hartley oscillator transmitters. It really looks the part with that 211 tube and the chunky variable capacitor. I've just completed a vintage 807 breadboard CW transmitter with HV power supply which was great fun to build. A very inspiring video. Keep up the good work. 73...M0DAD from North East England.
A great video as always and thanks for introducing me to the world of competitive vintage radios. I have a friend who races vintage (pre 1930) racing cars but I never knew there was an amateur radio equivalent.
I noticed the ARRL hand book on the table in there there is a 2m transciever which has a super regenerative RX a 6C4 and is made to become a M O PA on transmit I built it many years ago but very bad drift and modulated with a carbon mike had two QSO with it
After having done your nutube radio and your 12au7 regen with a 6u10 tube. It’s finally time to transmit. I want to use authentic parts where could I source them? This transmitter is beautiful and will look lovely in the radio pile
David, the Linc Cundall old time contest celebrates rigs like yours and it is coming right up soon in January.www.antiquewireless.org/homepage/lc-cw-contest-details/
@@MIKROWAVE1 True and perhaps even handily readable without a BFO, which I remember as being a luxury in the early days. My apologies, no insult was intended. 73
I have bought wirewound ceramic resistors. Solar capacitors. Using 600v .7 ma I’m not sure if I’m getting an output or not. What are common troubleshooting I could do for this circuit
I'm guessing nobody cares about harmonics and splatter. Is the FCC requirement for harmonic suppression and unrelated frequency radiation not in effect for these transmitters? HEY, let's make a nice spark transmitter! :)
