Hi Sholto.
I am doing some improvements, but very slowly. Actually I have the DXCC
database and calculation of bearing/distance ready for about a year already, I
just waited to get more new
My preference would be to follow the band plan. Assuming I understand
things correctly, on 30 meters it is intended that modes up to 2700 Hz
remain in the 10.140 - 10.150 sub band and all narrow digimodes (500 Hz
or less) in the 10.130 - 10.140, with 10.100 - 10.130 for CW. There is

What! You were on the frequency first and someone transmitted over top of you?

That's right, Andy. PSKmail uses fldigi and at Rein's request, the "sweet spot"

Tony,
Further complicating the static crash test conclusions is the effect of the
static on the receiver AGC. If a long AGC constant is being used, the static
crash is going to desensitize the receiver for as long as the AGC holds the
receiver sensitivity above the decoding threshold. In such a

Static crash resistance is not the only parameter to consider. The problem is
that you can have static and weak signals at the same time. MT63-1000 has a -5
dB minimum S/N, but MFSK16 has a -13.5 dB minimum S/N, so the static tests you
made must be at signal levels high enough that MT63-1

It depends which THOR mode is used. It seems THOR-22 is the best of the bunch
for static crash resistance. I've done a few static crash tests by generating
noise at regular intervals; the noise obliterates the signal in short bursts.

MARS has a different situation than the ham bands since you have a
dedicated phone communications bandwidth channel. And from what I hear
operators can use phone and data simultaneously with MT-63. We can not
do that on the ham bands below VHF here in the U.S.

Also the redundancy of the FEC treatment in MT-63 allows it to give 100%
accuracy with 25% loss of data.
In actual use, Olivia will do better under worse conditions at a large
loss of speed.
Contestia attempts to bridge the gap, but MT-63 gives the highest

You can send a mode command to fldigi from the jpskmail client. -> Mode menu.
Default is PSK250. Actually, in the original perl client for linux you can ask
the server to change
the mode once you are connected. This has not yet been implemented in the java
client.

That is correct, linkto = DK4XI-2.
QSY means you can ask the server to go to a traffic frequency, which is
normally 500 Hz higher
than the APRS frequency. Used here in EU on 10148.5

and one more question.
If I select PSK250 in jpskmail , and then execute a connect request,
FL-Digi transmits in PSK31. Do we need to set BOTH FL-Digi and
jpskmail to the same mode? I guess it makes sense but i am wondering
why there would be a mode choice in jpskmail if fldigi did all the
work.
I guess I will wait for conditions favourable to connect to a server,
20M seems like my best bet this morning.
Am I correct in thinking that is the server list shows a station with
an SSID, I should put it in the "link To" box as DK4XI-2 ?

It is less sensitive than others, but some of the most sensitive modes are not
