- Hellschreiber is one of the oldest digital modes currently in use by Ham Radio Operators. K9ZXO explains it all; history, theory and operations. Animations are employed to explain this strange and unusual communications mode.
Thank you for this nice Video. May be some day I will be able to do this communication mode. Now Im motivated because I found that Im an owner of the right Item at 2:28 from my grandpa. Years ago, before he died he explainde me tuning radio stations with this equipment. Its named Rudi. He told me they got crapped on when they used it during WW2 for civil Radio stations. 73 de DL1RCI
Very well made video. Hellschreiber (esp. Feld-Hell) is fascinating, because it basically is for the eyes what morse code is for the ears.. It also works with CW equipment, so very simple QRP transceivers like the Pixie can be used for this mode. That being said, Hell is no rival for Morse. In fact, most Hellschreiber software supports Morse code, too. ^_^
Very good explanation of how the machines and protocol work. I sure would love to have a real Hellschreiber machine in my collection!
Mark's Tech Channel ; someone did, check out the k7age channel. But it's all done by computer now.
2:32 Nice video from the American point of view. Only, the machine to the right isn’t a transceiver but a Wehrmacht Rundfunkpfaenger nicknamed Rudi, so a German army broadcast receiver so soldiers could listen to Goebbels propaganda.
Great video! I especially appreciated the signals matching the beat of the music at the end (ca 14:08), *really* groovy, gives me ideas! ;)
Thank you for these insights, very good video.
Just today 1/ 7/22 I worked an old friend on feld hell for an hr. on 20m. Hell forever (or something like that) 73 wb3dsj
I think you said that the transmitter drum revolves twice for each letter. I think it only revolves once each letter. It prints two lines of letters due to the two points of contact on the printer spiral. Please correct me if I am wrong. Very good presentation of Hellschreiber history and operation. Thanks. Ken S
I translate it as "Hell Script".
Love the narration, including the humor. Well done.
I came across this on 151.820 MHz while messing with an old police scanner earlier this week. I been hearing it all week in the evenings and into the night. Whoever is doing this is not bothering me since my radios operate in the GMRS and UHF commercial band but I found it interesting none the less. I have a general idea who it is doing it also but I need to wire in a VHF radio to my PC to decode it to be sure.
Go for it! I'd like to hear who you think it is - and what location.
So very interesting, thank you for posting the video.
While my digital mode software does have this mode covered, I in fact have never used it at all ever.
Very active on PSK31, RTTY45 & SSTV however favouring 30m, 20m & 17m at the moment
Thanks again 👍
Very nice description of Hellschreiber! Easy to follow and understand - thank you!
Very nicely done OM. I have monitored some HellSchreiber transmissions on 30 meters and found the mode quite interesting. Haven't made any contacts yet. Thanks for the nice documentary on the mode. 73 and have fun.
I would venture that the feldhell is a"character field modulation"
Since its viewing screen is 7 by 7 pixels...
Quite ingenious - thank you !
Very informative and well done. While I do not have any hf gear due to financial, time, space and many other factors ( sigh ) I'm with you. Nice stuff. Thanks for the videos. 73's
@j Mitch Hopper NICE history of early ham radio
I’ve been a ham for 33 years. Just started mixing it up with digital modes. I enjoyed Feld Hell the most. Usually using less than 5 watts. de n5vwn
