AW: [digitalradio] Odd mode around 7057

2010-06-07 Thread Siegfried Jackstien 
Some guys are trying ros 4 baud with bandwith of 500hz on 7055 USB!! So that
sounds like you received right that signals …

As many other modes ros is used in upper sideband … no reversing in the soft
(yet) so anybody has to use usb

There is only one qrg per band for the ros users (except 20m where are 2
qrg´s)

Here is a list for info:

502khz 1 baud mf mode 100hz wide (narrow mode for the mf folks)

1838khz

3598khz

7055khz

10144khz

14103khz

14115khz

18117khz

21117khz

24937khz

28295khz

50295khz

All  in 4, 8 or 16 baud with bandwith of 2250hz and center of 1500hz except
30m were only 500hz bandwith is allowed

On 2m there is 144.160 used for eme tests with bandwith of 64hz .. but that
something different than that what you heard on 7056

More info (and the software) can be found here :

If one of the qrg´s in the list above are making qrm (maybe on a packet net
or beacon or similar) you can write that to the author on his homepage and
if we find a better qrg for that mode he will make changes in the qrg list
….

Hope I could help

While on 7056 CW today, I heard a loud digital signal that was unfamiliar to
me. It was very wide, and sounded a little like across between JT65A and
ROS. I wonder if it is some new ROS mode and they are trying it out in an
odd part of the band.
