Heard you on 20M CW Sunday in the Ottawa area. You sure were chirping and drifting a lot. But it worked! Tried to call you but lost you due to RTTY over you. Thanks for the nice video. 73.
I love your builds! I hunt for chirpy wobbly, QRP signals anyways, because I'm wondering if it's homebrew. I also get harassed when my old FT-102's a couple hz off by the GPSDO SDR guys. I imagine you may be up for some serious roasting with your build. Fortunately most SDR GPSDO'ers don't hang out on CW. Old good power tube? That's probably a hard find. I only have a couple UV201's from the 20's. Not much power there.
Whats with the modern getup? You should have been wearing at least a jacket and tie! Back in the day you would be facing the wouff-hong as a corrective measure....
Thank you ! Quite a challenge. I am a former ship RO. On more than one occasion I worked a coast station in Jamaica that I suspect was using a power oscillator transmitter as his frequency stability was determined by wind velocity on the island. It was always interesting to send ETA messages to Port Antonio via this station. Power oscillator transmitters were once common for life boat stations. Spark transmitters were also legal in life boats for many years and would not doubt be an advantage is generating an attention in a distress situation. Some of the old door knob capacitors would have been nice in your rig. And yes I have used transmitters with door knob caps in them. When you are looking a HT in the 2 to 4 KV range big ceramic caps are or were the norm. Now that ROs are on the beach permanently 500 and 1000 watt MF and HF CW transmitters at sea are a thing of the past. Coast station KLC in Galveston Texas ran 20 KW on 500Khz. Solid copy was the norm for all of the Caribbean via KLC .
I am a very old guy and never heard the term RO. I find that some that use these trade terms, if that what RO is are bragging how hip and cool, they are.@@MIKROWAVE1
👍Excellent Mike and well done. Antenna movement changing load impedance and shifting frequency - we don't have that problem on modern rigs 😂.... lf I hear Dirty Drifty Chirpy (DDC) CQs, I always try to reply as I reckon it's probably someone with a homebrew set. I remember years ago it was quite common to hear CW that was a bit DDC from the old Eastern Block countries.
@@Capecodham I probably used the time to log some more FT8 kewsos. I have edited my initial comment to clarify. So, I didn't really save any time. Lesson learned, thank you.
Since my novice receiver was a used HR-10, I got used to a wide receiver bandwidth. Even with a newer receiver I still prefer 2kc bandwidths. Drifting isn't a problem. If I hear a chirpy, drifty cw signal I pounce since I'm always assured of an interesting chat. Thanks for the video!
We casual CW guys who enjoy the vintage gear always like the wider bandwidths, letting our brain sort it all out! How are you supposed to hear a guy running a QRP rig 900 Hz away if you have a 400 Hz filter inline?
I worked you on 20m Saturday, with my MOPA transmitter with two type 45 tubes. Your signal was good on the West Coast, more stable than most of the 1929 signals on 20m. VE7CNF.
This is a wonderful device, that you built over the years. I love it. All that chirping and drifting, I believe, was the sound of a 1929 pioneer 20m operator, most times probably a bit worse… And…Wasn’t that a lovely QSO??!! Thanks for this great video!
The great thing about the Hartley Oscillator is that is pretty much has to work, no matter the device. Spock would like it, because it would prove to be a reality check if it did not work.
Cool project! The 211 looks a lot like the 805 tube I have. But, did you pronounce ARRL correctly? Or is it "A" double R L? Or....eh? double arrrrr el? Maybe you can become a pirate in the open waters contacting Burt as your only line of safety using nothing but a spark gap transmitter and a cat's whisker detector receiver as you're going down. Great looking project, and interesting as always! 73's.
Thanks for entertaining and inspiring us. I replaced caps and cigarette residue in /on an SP600 this summer. More work than it sounds like. I plan to put an ARC5 TX on the air following your videos. Maybe a 6Meter convertor project 60s style?
Very neat stuff. I need to learn CW. Been rebuilding a massive (Hickok 209A) VTVM recently thats been on my oist for over a year and haven't been playing with radios. Also been on some digital projects, but need to get back to radios
A homebrew guy I know likes using bread pans for a chassis base. He built a 1920's style superhet receiver from scratch... Of course that needed a bit more than a bread pan, but the battery eliminator for it used one.
Yeah RCA and Armstrong had the patent that strapped all of the manufacturers to a licensing agreement if they were lucky enough to get one and only around 1929 for the latecomers. But the hams could make them from the very start.
It sound great to me!!!! Aparantly you dont realize what this is. Its simply a high powered oscillator. It is not a transmitter! And the fact that it's a 1920s design.

They watch the waterfall and assume it is some new digital chirp modulation scheme!
A lot of satisfaction building that old style transmitter and making contacts with it.

RO?
Radio Operator
@@buildstoys I wonder what he did with the time he saved not typing adio perator?
For you new guys - RO is Radio Operator.

Good stuff Mike, every year I say I need to try this, but ! I will listen for your sig ,73 , K9UT
Oh! Fantastic! Very warm! Great work.
Yes the warm glow of old valves!
Great video, as a lapsed ham is reignited my interest. Thanks
Absolutely fascinating.
Not as desirable as the 300b! $1500 used to be the price for a 'boxed' new pair.
They used to be desirable targets on the rifle range here.

Bigger is always better. a 100 mW single transistor oscillator transmitter might need a full sized rack cabinet for airflow.

With the chirpy output, can the signal be received without a BFO? Could you receive the signal with your shortwave crystal set?
Ha good comment. Well the trick here is to use pitifully filtered HV like grandpa did by using a Model T Spark Coil Power Supply! BZZZZZ!
Is it a 3V Heater type vacuum tube if so what about getting another and building a Buttlar Oscillator.
David, this archaic monster likes 10VAC at a couple of Amps, but it lights up so pretty.
Mike where did you find a schematic for a Hartley using a 27 tube, I have never found one. Thanks for the great video. Gary W8PU
OK I'll do a build video.
sounds bad.
It sound great to me!!!!
Aparantly you dont realize what this is. Its simply a high powered oscillator. It is not a transmitter! And the fact that it's a 1920s design.
@@jimw7ry well, i must appreciate that. just that it is not a pure sine sound
Amen. Between the component effects at high frequency, loading of the antenna, and the regulation of the power supply, it is a tough situation!
