The only other known use for voice-bandwidth data modes is for image
transfers,
which can send an SSTV-size picture, with a very
low error rate, in 30 seconds, using a bandwidth of 2400 Hz.
the same image, at the
same low error rate, can be sent in less than 2 minutes, using a
bandwidth
It seems that one of the effects of ARRL's clarification of new
modifications to FCC proposal is to tear down the famous 300 symbols
per second wall.
In place of that old wall, a new wall would be built:
A new 3kHz bandwidth limit for RTTY/data signals.
Prior to this, there was no bandwidth

If you went LSB, wouldn't that keep General Class licensees from straying
below
the 40 meter cutoff frequency of 7.175? UH, I think I said that right.

Hi Bruce,
I heard that in 1967.

I am somewhat relieved, if still confused about the language. Also, I am
certainly glad I never took up the law as a profession - the language used
is designed to confuse everyone else, and probably half the lawyers.
I am dead set against ANY automatic mode use of our bands during normal
Bruce,
Do you ALWAYS over-react, of is that just for this reflector? ;o)

Tony this is to low in the phone band for a lot
of us.
Understand John -- just picked that frequency at
radom. It was BCI-free at that time ; ).
Send an e-mail next time and we'll QSY.

Do you ever want to see a vote of all members of the
arrl? or better yet all hams as to if they want this?
You know damn well if wide band gets going all other
modes will be squeezed out ... why do you think the
RTTY/CW guys are livid right now ?
how many ARRL members will be left after this
I was able to listen for a little bit when several stations were running
WinDRM tests in the past week, especially Jason, N1SU, and another
station who I heard fairly well on DV, but K0PFX was only copyable when
on analog SSB since he was too weak to decode.
The sample you have sounds pretty
1. The folks at Booth, Freret, Imlay Tepper are unpaid volunteers?
2. One way to avoid such errors is to openly seeking broad review
beforehand; defects are less expensive (time, $) to correct sooner
than later.
The ARRL does a lot of things well, and deserve the appropriate
accolades.
Hi Tony,
I got the impression in talking to the WinDRM users on 7173 SSTV group,
that it worked with lower than +10 dB S/N. Maybe around 7 dB?
The older programs used the RDFT protocol which did require around +10,
and that is at least part of the reason for so rapidly abandoning RDFT
based
Dave,
1. Not the attorney, silly! I had to pay my attorney when I was
forced to take legal action against other Radio Amateurs, but
it was my unpaid volunteer efforts he was defending. Are we
in an adult conversation here, or what?
2. The Board (remember, those unpaid volunteers?) did seek
Does the ARRL post, and seek comment, when they plan on seeking new rules?
I assume that posting their proposals for a 30 day comment period would help
spot heir errors.

For what it's worth, I did some path simulator
tests with WinDRM and the SNR decode threshold
seemed to be around 8db. It was about 3 to 4db
