Could I suggest that PAX/PAX2 be considered as candidate modems formats?
Those are very robust modem formats, far better than the traditional
Bell 103 modems
for HF, and might prove to be better than Q15X25 in poor conditions,
specially on the
lower bands. Q15X25 is faster, but requires a

There is no point to either -- they are costly proprietary
formats -- contrary to good sense and Ham tradition.
Many manufacturers have tried the proprietary mode
idea and all have failed.

Your right. Same thing could be said for just about any mode
on a contest. I hope you was using RTTY as a case in point
and not picking on RTTY.

Hi,
Where can I find a good technical analysis of the real-world
propagation effects on signals in the HF bands, especially on the
digital modes? Preferably an online resource, but I wouldn't mind
buying yet another good book for my library.
I need to code a modulator for my voice codec, and

I understand most of the new FCC rule changes that will go into effect
on 11 Nov 06, but I am a bit confused when it comes to the digital changes.
Under Item 15 below, they state:
Nevertheless, our Part 97 rules do not now authorize amateur stations
to transmit both image and data emission
While I agree that we need to only allow non-proprietary modes on
amateur radio, it appears that it is about a decade late to argue that
point, as at least here in the U.S. it has been approved by the FCC even
with very sketchy outlines of the descriptions of the modes and even
with the

About Pax/Pax2, some weeks ago a Ham told me about
adding these modes in the Multipsk_Client program. Thisprogram (source and

TCP/IP link in almost all modes, Multipsk becoming a sort

I agree NO proprietary modes wanted.
I feel the same way about computer operating systems especially for amateur
radio...NO proprietary operating systems wanted.

There needs to be some sort of trade off between through-put and robustness.
In my dealings with individuals in disaster relief, they really need a bit
faster throughput that what MT63-2K can provide as well as just a bit better
robustness but if push came to shove, MT63-2K at a 0 or -5 dB SNR
Hi Ed.
I'm rarely on in the evenings and mainly on Saturday and Sunday afternoons and
on holidays...and on rare occasions as K5STB/P on Saturdays.

distributions or histograms of fade depths, durations and
Rick et. al.,
The commercial HF folks already have higher throughput data modes...close to
9600 bps user throughput (now RAW throughput) but the signal is 6-8 KHz wide
and they give this throughput at 0 to -5 dB SNRs.
Thus far DV hasn't made such progress but Thompson CSF and their New

I made my first Digipan/psk31 QSO last night in several years. It was the
first one ever on 40 meters. It's good to be back.
One feature request that seemed to jump out at me was the selection of

the X axis to decode --

that replays the last 25 seconds of audio, allowing you to decode any

MixW can open secondary or child windows by right click on the
signal of interest. As long as you leave these open (even minimized)
you can go back and read what was sent. I think you can open about a
twelve secondary windows at once. Even a different mode by right
clicking in the open

Leigh,
Loud and clear beaming west (5el monoband). Station NMO should be the Coast
Guard station in Hawaii. Not sure why it's on the bottom of 20M?

Yes, its a case in point, for digital/RTTY. Hey Im not just pickin on RTTY
ops - after all I are one. I have 220 countries on RTTY, 128 PSK, 323 CW
and 304 phone so no one can say I have really favored one over the other for
that, its just that I like CW a LOT more.

It was a coast guard station in Honolulu. I got them to turn it off.

There is also a series of moderate digital bursts between each ID.

Are these modes X25 compatable?
As in can they be used within the packet radio network?
This is something we are currently looking for to help increase and
replace the 300 Baud HF standard that has been used for far too long
now within the packet networks.
At present we are looking at Q15X25,

Is there a sub-band conflict in the new FCC rules?
The FCC Report and Order says they will allow Extra Class Voice
