I was surprised to see your comment that Pactor and Clover could be used
via sound card modems if they were not proprietary. The conventional
wisdom is that these modes require a much too fast switching time to

When you say ICOM digital voice modes, are you referring to the D-Star
system developed by JARA? This is a sort of open system, although it
is not quite as open as some of us initially thought. The vocoder uses
the proprietary AMBE product so that does complicate things. Also it
does not seem
I doesn't sound like this mode would require much change in software,
but if you have a rig with some kind of unchangeable firmware, I can see
where AQC would not work. If we ever did get ALE placed in amateur rigs,
it would be wise to have it in a flash eeprom form that can be updated

Thanks for some real world experiences. I have no doubt that if you are
running close to the MUF you can run the high speeds with strong
signals. Based upon the published numbers, the signal has to be very
good, and often well above tests that I have tried using the RDFT based

GM Rick,
Alternate Link Call (AQC) ALE is basically 2G Plus ALE in that its an
advanced 8FSK form of ALE where most all of the un-necessary overhead
of ALE has been removed and new capabilities have been added, to
include a PSK burst mode. The linking time to setup is must faster

Hi Andrew,
I don't know what has prompted this thread on your part, however, the
only threat to ALE is AQC-ALE in my opinion and that's not at all
bad. However most Amateurs that are working with ALE have yet to
realize the full potential of ALE, let alone the potential of AQC-ALE
that is

I wonder if ALE for amateur radio use is in danger of demise as the

The public's demand for a method of recording video was such that one
format survived and the industry flourished. With ALE that
Walt et al, I am convinced of its usefulness...I would just like to see
more hams use it. To facilitate that, we need an easier on-ramp.

Steve,
Can you give us some current information on AQC-ALE? I had not been
familiar with this term but did a little web surfing and found a very
interesting document:

That covers a rather full spectrum of digital modes,
