The FCC could make part 97 more understandable if they adopted regulation by
bandwidth but that effort died. EZPal on 14.233-14.237 MHz is OK as there
are very few restrictions on image transmission.

Had the ARRL's regulation by bandwidth proposal been accepted, the range
of frequencies available to automatic stations without busy frequency
detectors would have significantly increased, which was why so many amateurs
opposed it, which was why the ARRL abandoned it.
73,
Dave,
I just reread it and it seems to be more restrictive than the current rules.
The current rules establish segments for automatic forwarding between
digital stations on all HF bands and these were eliminated below 28 MHz in
the ARRL proposal. The current rules allow for an automatic station that
What about ALE-400? This is a mode that I have never used. I have finally
installed mutlipsk which offers this mode. I would sure like to get some
hands on with ALE-400.
Oh yeah, I second the motion on Feld Hell. Thanks KT.

Your assertion below that current rules allow an automatic station to
operate on any frequency is incorrect. See ยง97.221
http://www.arrl.org/FandES/field/regulations/news/part97/c.html#221
With a bandwidth of 500 hz or less, such stations can can only operate
wherever RTTY or data emissions are
If people want to use those other modes ...go for it. I did not include
THOR or ALE400 because they are not common to all three software packages.

Definitely apples to oranges, Andy. One doesn't even need to get into a
discussion of speed (although I've finally tweaked things so that I reliably
get ~1Kbyte/min on a 1.6KHz mode S9 connection with 1-5K payload).
The most important difference is that there is no promise of FLARQ being
Quite true, but there is a network of ARES and RACES groups slowly beginning
to see that FLARQ is quite effective. When WINMOR moves to peer-to-server
operations, it will be interesting to see what happens. WINMOR also has the
Telnet and packet capabilities.

Andy,
Thanks for the Flarq tests last night. That was really fun. I can see
how useful this can be in emergency communications in addition to a
program like Winmor. Winmor with its capabilities to send email through
the Winlink network and NBEMS with its peer to peer capabilities to send
I meant any frequency where RTTY/data is allowed. The objection that people
had then seems to be that a wider bandwidth was allowed for semi-automatic
stations in the proposed 3 kHz bandwidth segments.
However, the proposed rules would have pushed the wideband semi-automatic
stations up in
I agree that there were positive aspects to the ARRL's regulation by
bandwidth proposal. However, expanding the range of frequencies available
to unattended stations without including a requirement that they verify
their frequency to be clear before transmitting was a showstopper, in my
opinion.
Hello Tony,
What are the numbers that you get?
In fact, from my measures, the first decodings appear at -19 dB in RS ID and
-16 dB in Call ID (but respectively -16 and -13 dB for almost 100 % success).

Tony (K2MO) is preparing a paper about the way to use ALE400. Here is a
