guessing the freq is around 1807, but when ?
david/wd4kpd
I wonder if group members might want to use 1808 KHz as the frequency
for 160 meter digital modes. And that means the actual frequency. With
the ease of seeing the bandwidth on waterfall displays, I favor
centering on the frequency. This means that you need to put your dial
frequency at the

Keep in mind that the PropNet folks are using 1807.5...
Is it the band or the mode ? ? ?
It seems to me in my 35 years as a ham that 80 and 160
are at it's best this time of year.

Again, I see no reason why we would want digital signals down that low in
such a wide band. That first 25 KC or so is used heavily by CW stations
both here and DX. I dont care what someone else arbitraily decided was the
bandplan for digital. Those bandplans are NOT worldwide, and until they

They don't have a switch in there that allows them to talk to non-

If not why doesnt some smart company put a switch in a radio that

As far as I know all the ICOM D-Star user radios can run analog or D-Star.
The D-Star digital repeaters are digital only.

Hello to all,
There are also some basic axioms (I suppose so) as:
1) Doppler iosnospheric modulation acts on PSK modes (the phase is dancing
randomly, the Costas loop cannot stabilize and the PSK decoding is quite
impossible). The more the modulation speed is, the less this Doppler acts on

If we don't stay with the bandplans, then we can be sited by the FCC for
not following good amateur practice. The ARRL Bandplan is the defacto
bandplan for the U.S. That is why I don't venture out of the digital
part of 160 meters when using digital text modes. Ideally, CW stations
John,
Most of us simply can not possibly know or even care about any
particular use of any particular frequency as long as we are properly
operating within our subband and mode. The one exception might be the
area of automatic operation around the 14.100 beacons and maybe others
in the world

I don't care either. I don't use PSK myself. the only reason I bring
it up it that the PropNet station broadcast a beacon so many times
an hour. I just don't want to see a load of whining and crying when
someone gets QRM by one oh the propnet station like they did
over the pactor station.
You are right about the FM operation. The main source of information
that I had a few years ago was the group that had a web site on this
unit and their testing of the data throughput and voice distance. If
they discussed any use of analog FM, I completely missed it.

John,
Is it your understanding that they are running unattended beacons on 160
meters?
Under Part 97 rules here in the U.S., it does not seem that you would be
allowed to transmit an unattended beacon on that band. And if you did
transmit a beacon, the bandplan calls for 1.999 at the very top
Key word being *unattended* ..
I can not speak for the stations on 160 but I do see the reports

It turned out that the PSK31 station was a Propnet station:
