No, Hank, "the data network as you perceive it SHOULD be?". That means your
well expressed views quoted below and elsewhere.

I am very clear about your perception and the difference.
I am very clear about my perception, as I expressed it clearly. I have room in
my view of the ham radio packet network for many of the options that have been
espoused by others and villified by you and Charles.
I have no reason to believe the discussions here are much more than
"religious"
arguments that will not be resolved until they are rendered moot by associated
events that cannot be denied, ignored or misinterpreted.

Subject: LOOKING FOR PSK QSOS
I am a new op on Psk31. Find alot of action on 20 meters, but other
bands are pretty slim pickings. Looking for skeds..tests...qsos...on all
bands 160-6 meters, especially would like to try 30 PSK.

Yes, it's true...
It was just over ten years ago when I organized what was almost certainly
the first experimental use of a forward error checking protocol over a
digital repeater.
Others may claim that what I really did was to (1) forget that my PK-232 was
in AMTOR instead of VHF Packet mode and (2) forget that the 2-meter rig was
hooked up, tuned to the local voice repeater instead of the local Packet
frequency.
- But I prefer to think of the incident as the first experimental use of FEC
on a digital repeater in the state of Texas.
That sounds a lot better, doesn't it?

There's a funny commercial where this guy is interviewing
for a job. Every question asked is answered with a weak
shrug. When the interview is just about over, the guy
hoists a six-pack of beer onto the table. The interviewer
says: "You're the Man!"

Yes, it's true...
It was just over ten years ago that I organized the first international
experimental use of digital voice mail over a packet radio network.
What I did was to make a Windows 3.xx WAV file of myself saying "Howdy from
N5PVL" or something equally original. Then I used 7-PLUS to turn it into an
ASCII file and cut it up into a large number of 20kb pieces. It took all
night and part of the next day, but I finally managed to forward all the
parts to XE2XPK, a Mexican BBS operator who lived just over the border.
Sergio put them all together again with 7-PLUS on his end, then listened to
the WAV file.
Thus did Sergio and I pioneer the use of digital voice mail over packet,
back before voice mail was cool, or even widely known.

Charles:
I'm supprised you didn't pioneer that new mode everyone is talking about
"VOMT".
VOMT - Voice over Morse Telegraphy!
Charles, how about some comments on my Bandwidth to Burn thread?

Subject: PSK31 and the interface
I have been reading about this new mode, but I
have found nothing that is radio specific with
regards to an interface between the radio and the
soundcard. My txcvr is a Yaesu FT990 Are there any
manufacturers of these interfaces? Any information
regarding this fascinating mode will be
appreciated. Stan VA3DS

Subject: PSK31 and the interface
Stan, you don't need any interface as such. Audio output from the radio
is fed into the line input of the soundcard. Audio output from the
soundcard is fed into the mic/audio input of the radio which operates in
SSB. The PSK31 program, or others, controls the entire operation from the
computer. That is all there is to it . . .
As a practical matter, most of us find it necessary or desirable to
isolate the radio inputs and outputs from the soundcard with 1:1
transformers from Radio Shack. And most radios require a simple resistive
divider in the mic input circuit to prevent overdriving the transmitter.
PSK31 is being used with almost every kind of radio you can imagine,
including homebuilt QRP jobs. I operate with an Icom IC-765. I have read
of several others who run the FT990.
Suggest that you visit the PSK31 web page at
psk31@bipt106.bi.ehu.es
for details and download of a PSK31 program.
PSK31 is a remarkable system originally aimed at keyboard-keyboard
chatting on HF although it has been used very well on VHF and UHF. It
even works with audio coupling only between two computers! That mode is
sometimes used for demos at club meetings, etc.
The programs support exchange of text files as well as normal keyboard
