Would be interesting if you could scan 10147.0 and 18105.0. there is a lot if
RSID'ing there from pskmail stations.

Regarding Spread Spectrum Notice of Proposed Rule Making (NPRM)
http://www.arrl.org/news/stories/2010/03/18/11396/?nc=1
It proposes to reduce some of the restrictions on Spread Spectrum but
unfortunately does nothing about permitting the use at HF and VHF of SS modes
that completely fit within
Extensive tests on 70cm using ROS 16 baud spread spectrum have been
disappointing. ROS appears to be unable to survive the Doppler shift and
Doppler induced flutter so prevalent on that band. The hope was that
ROS 16 baud would make traditional communications possible that were
difficult on
I read the proposed rule making and did not find any reference to
frequency/band. So, where is it saying SS is allow but only on 220Mhz and
above ?

Andy,
As I read it, the NPRM did not disturb the current FCC ruling that
spread spectrum is only allowed above 222 Mhz, so that is still in
force. What it did was modify the power and power monitoring requirements.

Nice work, Skip. Confirms the gut feeling I had using the mode on HF although I
only had the chance to make a few ROS contacts before I was banned. It's a pity
more users didn't try something like this instead of using it to make endless
macro exchange contacts that proved nothing and wasted

Frank,
It is really Commander that performs the band changes , then Multipsk with the
decode.
1. Set Commander to scan specific
Hi Jose,
We will be starting with tests of ROS 1 baud tomorrow but I will not
have any results until next week, after we have been able to make tests
over several days and under many different conditions. The tests with
ROS 16 baud have been finished and our results are as I have already
Skip,
Just a thought, but raspy signals on VHF/UHF are usually associated
with aurora. Can you correlate that?

John,
The raspy sound is similar to that associated with aurora, but this
far south, aurora is very rare, and the raspy tone is there almost all
the time, every day, if there is no propagation enhancement. So I don't
think it is caused by aurora, but if you picture how aurora looks
visually,
