Thank you! I'll be sure to check that out.
not possible to give the real RST ?
to give all stns the stupid 5nn is really unreal and makes me confused about the brain iof the hamradio operators
Very intresting, thank you 73 on6wv
Incredible life-changing technology that was almost entirely made obsolete in the next thirty years.
Great Stream, Great Stream!

Excellent instructional video! May I ask how you came by this artefact from the past?
Film archives from US Airforce
If these were the only things in schools, today's kids would be brilliant (and there wouldn't be tampons in boy's restrooms).
I don't think the people behind that sort of social change are very interested in STEM!
If these were the only things in schools the real reactionaries would be calling you a blasphemer for promoting witchcraft. Why don't you mind your own business and leave others alone?
@@enricofermi67 please don't go near any schools.
VOK signal usually quite strong in Nevada and California.

Interested
hey how is every 1 blessings all around thank you
I would check it out when I can
Yes I am interested in hearing more about ham radio , space conditions and more on your livestream on Sundays
looking forward to it!
I’m a ham radio operator KD5SVC. Very nice to meet you and I will be interested in listening. Absolutely!!
@@cindybeattie-rich3728 Awesome! I'm hoping for at least five viewers to indicate interest, so I can plan. The first live stream may be as early as this coming Sunday, or at least by the following weekend. Thank you for your interest!

_”Other modes that creep in and push us around”?_ Do you mean *<cough>* RTTY contests *<cough>?* I remember working *JT65a* on 14,076, seeing those big, wide RTTY _"railroad tracks"_ and wondering if they'd even notice a skinny JT65a signal *BETWEEN* those two frequencies ... 😀 *73 de AF6AS*
Is the RSID modulation method more robust than _Olivia_ itself? IOW, under _weak signal_ conditions, is it likely that a recipient would be able to copy the _RSID?_ *73 de AF6AS*

You wouldn't happen to know what song that is would you?

What exactly am i hearing?
You are hearing pilots of commercial jet pilots talking with international air traffic operators, on shortwave radio.
Gander is one of my favorites - Townsville Australia SDR play 2 pro W6LVP loop
Hearing both Gander and San Francisco shows how great propagation was last night. And, yeah, it is great listening. In past years, I have even caught medical emergency radio traffic when passengers get ill and the crew needs to consult with medical professionals. Most of the time, just routine stuff, but then you hear something very different!
Get rid of the music
Hi. Nice presentation. Just getting back into Ham radio after about a 4 decade absence. My initial focus was getting better setup on my sailboat for marine safety enhancement, which came with an old marine Icom M710, so I have taken my new Yaesu FT-710 and set up FLdigi as far as receiving weather FAXs, and established Winlink Express with VARA HF. DX chasing is not my thing, so FT-8 is probably of not great interest. I'll continue learning about Olivia on the web site, and maybe give it a try some time soon. Thanks for this.

Thanks for the great historical video on CW! Such an important communication mode.
April 26th,2024 18:30. I am retired now. I am considering Ham radio and more so Morse code (CW). I love history, but as you mentioned, i too can be drawn into an interest that leads to more questions and on and on. I was introduced to C.B. (11m) radio in the 70's and used it to communicate up to 12 miles across our lakes in northern Saskatchewan (Canada) especially when i had to go out by boat after dark to search for one of our lost customers. We had a Angling Lodge and every year, several folks wouldn't come back by dark. My wife would stay up until 02:00 to keep in radio contact as i and my hired man searched the countless islands and bays hoping to find them. Always aware that our current cell sytems, power grids, etc. are taken for granted and one day we will find ourselves, once again, in need of independant radio operators for vital information. And Ham, in contrast to Citizens Band (C.B.) is legal to use amplifiers to reach further, when skip is not available. Todays internet can give us the world but it doesn't (for the average person) give you a direct connection to someone on the other side. Lastly, as one comment i read in a utube video on CW, Morse Code can keep the aging brain from collecting cobwebs! Thank you for your video...even though its 6 yrs old. :) Cheers from Saskatoon, Saskatchewan, Canada.

Glad youre back!
Amateur Radio Operators often set up at county fairs and take radiograms to send. Try it if you see one. Its a novel thing these days but still works. Better yet become a Amateur. Easy and lots of fun. Great post. Awesome old equipment. Thanx.
I was able to receive this signal with a homemade regenerative receiver that was designed with a narrower bandwidth than most receivers of this type. Noisy, but completely legible.
Very good instruction video, really helpful. 73 PA5BAS
Tom- Thanks for your efforts in promoting a "conversational" digital mode. I've learned allot from different youtube presentations and alway appreciate the time and willingness to push back from the radio and put together something that can benefit the whole amateur community. Elmering is the highest form of Amateur Radio. Well done good and faithful Ham.
so what does the code mean?
Where do I download software
just found this station on the SDR. lead me to your video! we live in the future!
Lastima que no se pueda traducir a otro idioma el video!!
