Steve,

Crickets. UGH! Terrible!!!! Scandalous.

ITTY is no trade secret. The basics are documented at rtty.com. You can also “see" the setup here:

https://www.youtube.com/watch?v=Hpek2ujfGQ4

(although that video is old and the rack has been improved with ASUS PN40 computers for the front end, “racks” for the Raspberry PIs, and better power management throughout)

You seemed from the get-go to want to go your own way, which is totally fine. And you did it! Others have done similar things, each doing it different ways. For example, Jordan broadcasts his specials throughout the year.

In your case I believe you made the equivalent of a SDR for ITTY: totally in software. Whereas the original ITTY system is more of a hardware implementation with modems that generate the tones. Years ago when Bill and George created ITTY, I suspect the audio cards in computers of the day were not good enough to generate high quality AFSK and so they chose to use the modems to generate the exact tones (exact being the key word because George wanted exact frequencies and he chose the very expensive ST-8000A modems to get it). Bill actually created support for software generation of the tones but they did not use it.

I realize that I live in the past because I think it is cool to use old/retro gear and I use HAL, Dovetron, Electrocom and other TUs (blinken lights!) all over the place driving heavy, old, rock soling teletypes; others want nothing to do with that kind of thing and use MMTTY, fldigi, and other applications including glass TTY. No commentary on that - plenty of room for everyone (except I despise glass TTYers on HF RTTY who don’t put in CR LF at 72 characters!)

Maybe it's not that l live in the past. Maybe I just want to preserve the past.

George originally used simplecast for the streaming. He had Windows PC -> ST-8000A -> Windows PC -> Internet, all PCs running Windows XP. When I moved his setup to Arvada, I did not want to touch windows XP. Simplecast did not work on Windows 7 (at the time), and all the streaming software for Windows was expensive. I chose to use icecast with darkice for the streaming. I have not heard of Ices2.

(More on living in the past: I’m an HF guy who is not into digital modes like FT-8 and PSK-31. I have nothing against that, I am just not interested in it it. I am not interested in hooking a computer to my radio or replacing my radio entirely with the computer. I do enough with state of the art computing in my day job. My hobby allows me to escape from that. And yes, I’m becoming a rare breed. Feel free to call me a dinosaur as long as it is in good fun and you have room in your heart for dinosaurs. Just don’t hold your nose in the air about the way I think and want to live - I certainly won’t do it to you).

I offered to create my own iTTY and asked for the help from this group.
This group has been very helpful in every other aspect but when I asked for information about creating my own iTTY all I heard was crickets.
Seems to be a trade secret.

I figured it out on my own.
If anyone else wants to create one I recommend using IceCast as the server and Ices2 as the client on Linux.
The hard part is converting text to RTTY modem tones.
I solved that using Sox and a Perl script.
Another possibility is a Perl module called HAM::FLDIGI using XML RPC commands.
I did not purse that option.

No need for a hardware TU. Do it in software.

I use it not all the time, but often enough that I rely on it being there. And have never been disappointed when connecting to ITTY for testing purposes or doing demos on some of these wonderful machines to kids of all ages.

YES I like it and use ITTY and AUTO start interchangeably. Haven’t tried the ITTY 100 or the GREENWICH.

Couple of times a week and during the special occasions most certainly.

And use 100%, as a true enthusiast, copy on a clanking, oil and paper spewing machine!

Subject: [GreenKeys] ITTY Poll

Dear fellow GreenKeyers and other interested persons:

I am doing the semi-whenever all ITTY interest poll to see how we are doing and to see the results of any input for what might interest you that is possible on ITTY.

If you should know of someone that is not on GK and would not see this message, would you kindly forward it to them.

We thank you for your continued support and past input to the service started by George W7TTY Hutchinson over 20 years ago - has it REALLY been that long??!!

Please reply to til128 at juno.com

Here we go:

Do you like the ITTY service? Yes No

If no, stop here. Thank you for your honesty.

Which one do you listen to most often?

Second choice? Third?

ITTY: HTTP://INTERNET-TTY.NET:8000/ITTY
AUTO: HTTP://INTERNET-TTY.NET:8030/AUTOSTART
GREENWICH: HTTP://INTERNET-TTY.NET:8040/EUROPE
ITTY 100: HTTP://INTERNET-TTY.NET:8010/ITTY100

How often do you listen?

And to which service?

All the time?

Once a day?

Couple times a week?

Once a week?

Only when something special is happening?
IE: Santa Tracking - ITTY calendar - Halloween (War of the Worlds) - pictures

Would you like to see the 100WPM channel turned into autostart or leave it as it is as a "news" channel?

If you listen to ITTY, do you use a glass TTY, or are you a true
enthusiast and copy on a clanking, oil and paper spewing machine?

Thanks again for your time, and thanks to all the people who contribute to all the ITTY programs.

Thomas WB2TTY Tillson
