Steinar,
I've been monitoring ROS on-the-air and I've done some testing with the
HF path simulator. In my opinion, it's about as good as one would expect
from an MFSK mode with a relatively slow baud rate. Tests show that it
will outperform RTTY and PSK31 in poor channel conditions (most MFSK

Hi Tony,
I have often switched from FH to FSK-Hell when working the States from
VK via the Long-Path on 20M when conditions are poor.
Often switching to FSK was the only way to complete (or even initiate)
the QSO and the improvement in copy was often quite dramatic, from very

All,
I spent a little time this weekend comparing FSK-Hell to the standard
Feld Hell mode. FSK-Hell is a modified version of PSK-Hell which was
developed to improve readability over HF. The difference tends to show
up more on long-haul paths where signals are more likely to encounter

Andy,
Most of these are encrypted so don't expect much to read.
A good one to try in the USA is on 8.4785MHz USB. They often run a test tape in
the clear. When tuned in (and the right parameters set) you should see:
