Hello to all digital fans! I found this at youtube today and it looks like very promising for long range chat messages. Maybe something new what we should check! Watch the Video:
I watched the video as well. I see some potential! Im excited to see how it develops. Thanks for posting.
For those who don't want to have to sit through a video for basic info, it's called "LongChat," and check out https://www.qsl.net/yo4tnv/HamSoftware/DIGITAL/LongChat/ It seems pretty new, so LongChat doesn't yield much on a google search yet. I haven't really watched the video yet, but I'll be interested to see what the slickness is compared to other FEC chat modes.
So basically no description of the emission mode itself, other than it's a chirp. It has FEC but it doesn't say what kind of FEC. And weirdly his descriptions are only about how to run his software on three specific rigs, rather than the more generic "here's the audio part, here's the CI-V" that other digital mode programs use. As described, it has a net throughput of 40 bps in 2.4 kHz bandwidth, and his video only shows it on VHF where there's plenty of bandwidth and not the same kind of noise as HF. So far I'm not impressed. If it turns out to be any good it should probably be added to fldigi.
I downloaded V1.0.149 and installed it but all that happens is a dialogue box comes up saying to download the latest version. No link to where that is, nothing on the index page of the download site quoted gives any clue as to how to get to a more up todate version and neither entering the callsign "TA2STO" nor the name "LongChat" bring up any links to where to go to find an updated version, so just about useless...

YADM Yet Another Digital Mode Pretty soon no one will be able to carry on a QSO due to all the different modes that have nothing in common.
FlDigi with TXID/RXID is your friend. We long ago passed the point where most digital operators could recognize all the modes used on HF by ear or visual waterfall. With RSID, the program transmits the digital TXID equivalent of "The following message is in Really Cool Mode RCM" and the receiving program sees that as an RXID and auto-switches to decode "RCM". It's more of an issue for modes based on a single piece of software, such as JS8.
"Chirp mode" with FEC? For a keyboard chat.... Didn't that used to be called AmTOR? While this Long Chat as a distinctive sound, so does AmTOR.
My comment was more to the point that new code schemes are coming out in a period which seems like daily. Each developer hopes to create their own following like WSJTX and JS8Call have and make users dependent on them for updates/improvements in the software. Typical software developer mindset. There really is not revolutionary jump in technology here, just a reach for the next shinny thing. This only serves to divide the community more. I'm not a fan of change for change sake.
to tell the truth the operator transmits and receives on 6m... I think we see VHF only because he hasn't set up any CAT connection with the encoding software on the RSP1
Being a ham since early 70's, it is true that amateur radio has had its success based on experimention and developement by hobbyist, and that is still true to this day. However, i think there comes a point at which the exponential increase of newest "next best thing" becomes detrimental to the hobby. I installed WSJT-X this spring and instantly got hooked on FT8 and FT4. I also installed FLDIGI and was confronted with so many protocol options that i didn't know where to start. I recognized the sounds of rtty and cw, but for the other "sounds" i did not know which mode to pick. Some "Mode/Protocol Auto-Detect" button on some of these softwares would be nice, but i guess that's really hard to implement. The developers do a great job at getting this stuff working, and trying to stay on top of it all. My wish is probably just a pipe dream 73's "Rej" va3dwh
I'm a Linux user and my shack "PC" is actually a Raspberry Pi400. Unless there's an open source version or well maintained port for Linux (ARM & x86/AMD64) then it's no good to me, or a lot of hams. That said, it's clear the developer is still at the very early development stages, and should be encouraged and praised for their efforts. This is after all, an experimenters hobby! As others have said, they will need to better document their mode for it to get any real traction and if it really does bring something new and exciting to the table, perhaps the developer should work with the fldigi developers to integrate this new mode into the existing relatively mature multi-OS platform?
I have 2 Questions. 1. Isn't that close to "out if band"? 2. I thought that 50.0 to 50.100 was for CW only.
