Over the past couple of weeks I have been testing a SCS PTC2 usb
modem with
a pactor3 license, and have come away amazed and humbled by what
this thing
can do.
Thanks for sharing this John. Since I have only a passing interest in
emcomms, how is a SCS PTC2 with P3 for just basic ham
Phil's paper is from many years ago but the reality is that there was no
further movement away from the legacy AX.25 equipment toward a new
layer, much less toward a completely new protocol.
There is some movement...

Has anybody set up a Shoutcast or similar Internet radio feed of a psk
radio channel like 14.070?
I wonder how the latency and jitter on an TCP/IP audio feed would be tolerated.

My point is that the packet radio cannot prosper if all of our
_amateur radio_ applications are closed source.
Closed source or open source is a non-issue. What matters is if the

open source package with no support is far

No one wants to crush the older modes -- but they can't block moving

Could you enlighten us on just exactly what modes are being blocked
by the current regulations. What bands do these modes operate on?
What is the purpose of the blocked modes?
That's a big part of the problem with the previous proposal. It

Bill,
What you have left is noisy HF.
So this is the time to try PSKMail. Its only (ONLY???) 200 WPM user

WPM? What is WPM? Bytes per second is a fixed measure. Assuming 5

I will also ask the question again:
If we had the ability to send high speed digital data on HF, what would
we be sending to each other that we don't do now?
Anything. Everything. There's no 'technical' reason we don't do
everything on HF. Discussion groups like this, pictures,

How about some real world 21st century RF modes using 9 KHz or 12 KHz
data channels? None of those 1980's restrictions using mere 3 KHz.

My picture was using Ham Radio in emergency situations, or in remote

What I have never understood is why we can not develop a system whereby HF

basic system that does not itself require a complicated and fragile internet
system. It is probably not possible since the routing issues are
