[digitalradio] Continuing evolution of HF Ham radio communications:
Regarding the continuing vocal disagreement (and flame-wars) between the live chat operators, Morse operators, and the BBS/Winlink or ALE network operators: Two HF bands are discussed below as examples of possible ongoing evolution throughout the amateur radio service's spectrum allocations There is some history that relates to the popularity and use of various non-Morse operations prior to year 1995, and now . Non-Morse operation in the past was only live keyboard to keyboard mode until the innovative spirit of amateur radio operators realized the value of ARQ modes for error-free message handling, starting first with HF Packet forwarding. Back in the stone age of amateur radio, and before the advent of sound-card modes, the prevailing location for Amtor and pactor was specifically between 14070 and 14080, with 14080 to 14099 being for RTTY operations. Back in this Stone age, 40 meter Amtor/pactor was allocated to the 7070 to 7080 KHz segment, and RTTY operations from 7080 to 7099 KHz As time passed, fewer individual stations were using Amtor/pactor/G-tor for live-chat, which left primarily the pactor stations being used for BBS mailboxes and message forwarding ... This change in usage was primarily due to the preference of radio amateurs to adopt less-costly methods of digital communications that did not require the investment of $300 or more for multi-mode TNC's of the time such as the early versions of the Kantronics KAM; MFJ-1278, and AEA PK-232 hardware modems. A solution to the interference problem between ARQ modes and widely popular sound-card, and other types of Live chat modes using data communications would be to migrate live-chat operations farther down the band, such as 7050 to 7070 , and 14050 to 14070 Due to the elimination of Morse code as a requirement for an amateur radio license, it is likely in the future that the current use of the RTTY/DATA bands would be inverted in usage, i.e. Morse code operations would *primarily* be in a more narrowly-defined sub band, while data modes would exist over a much larger band segment in each amateur radio band than Morse operations ... On a legal basis, Morse operations would continue to have access to the full allocation of each amateur radio HF band... This may ruffle the feathers of the old-timers, however Morse code will still be of major importance as a very simple and manual mode of communications when more robust modes are not available.. Morse code will also remain important in the future as a part of living history ... It is likely in the future that, for example, Morse operations may be in the 14000 to 14050 segment, and data modes between 14050 and 14099 and 14101 to 14120 KHz, while Morse operations on 40 meters may be between 7000 to 7050Khz with RTTY/data between 7050 and 7150KHz. Message forwarding operations would likely be toward the upper-portions of the RTTY/DATA bands, while manual, Live chat operations would be farther down in frequency with respect to the BBS/forwarding stations (whether they are Winlink or other modes yet to be developed) Flame on this idea if you wish, however robust live-chat sound-card modes, ARQ messaging modes, and Automatic Link Establishment (ALE) modes will all gain increased popularity, acceptance, and adoption because of their more efficient and reliable communication capabilities as compared to manual and non-keyboard modes ..

RE: [digitalradio] Re: Trouble at mill RTTY contesters war with HFlink
That's the way I look at it, Bill ... soapbox A sounding message is simply the station's callsign as the ALE ID, and soundings are only done if the station has an operator present, otherwise, the unattended stations are simply scanning the channels on the HFlink netplan, and only respond if called by another station.. As far as the sounding messages, they are no different than coming up on the air in any other mode and saying .. This is wa6ube... .. As Rodney King would say ...

FW: [digitalradio] Re: Oregon Governor Allocates $250,000 for Digital Communications Network
Rod, it is really great that you are a member of both the amateur radio community and the public safety communications community .. It does amaze me to see some members of the amateur radio community start whining after public and/or private agencies officially recognize ***and support*** the value of the amateur radio service during disaster response and recovery operations, and then especially start whining when Winlink is being adopted as a redundant means for email communications. FWIW, our City of San Jose Office of Emergency Services has had HF/VHF/UHF radio communications equipment installed in both the main and alternate EOC locations since the early 1990's and has recently been upgraded with replacement equipment over the past two years. It also includes HF Pactor and VHF/220 MHz packet messaging as part of a County-wide digital messaging infrastructure. The San Jose equipment includes not only amateur radio equipment, but also commercial /\/\otorola, and Harris equipment that is used in the amateur radio service by our ARES/RACES volunteers.

My experience with the ARES units in Oregon and our local County OEM is that the equipment that they, the Government, buys for ARES use STAYS with and FOR ARES use! We have a VERY, VERY proactive EC in our District and trust me when I say that the County Goverments and the State OEM keep their hands off the Hams! After all, Hams are VOLUNTEERS and it wouldn't take much for the Hams to back off and let the State and County Governments to flounder and get a very BAD reputation! No, this money that our Governor has given the State OEM for this project is legit! Our Amateur Radio community has impressed him on more than one occassion and he's serious!

Hello Howard, I use Pactor I every now and then for keyboard to keyboard. It is hit and miss for me; more a novelty than an oft-used mode. Interesting. Thanks for the reply, Bill. I asked about this twice now and yours is the first reply. I asked also on the PK232 group with no response and that surprised me a little. Well, I have my original PK but without current upgrades. I would like to put it into use but if it is seldom used by anyone, I wonder if I might just want to pitch it. I think it's a neat box and despite my liking PACTOR if there's no chance of enjoying the mode much and no one is interested it making the mode more active... I like the mode myself but then I suppose I'm old enough to want to hang on to familiars now I suppose. I'm 62 and while I like SOME of the new modes now out, I still enjoy RTTY, CW and (heavy sigh) PACTOR. H, I even like the idea of digital voice and DIGI file/pix transfers, and SSTV. Where do you operate? Is it hit 'n miss or perhaps a schedule? I have PKware installed and it's worked very well over the years. I've been told that one use of the PK is to implement the upgrades to take advantage of what is called superior filtering for PSK and RTTY and such.
