Hi Guys
Andy, the frequencies listed on the web site are for APRS 300bd, except 10m
which is 1200bd. The setup I describe is specifically as an adjunct to Net14
and not a PSK-63 general QSO frequency.
With regard to Long/Lat v Grid Square, the choice is yours but the Grid Square
shortens the
I'm still confused... if I want to try PSK63 instead of 300 baud packet, do i
use the same frequencies and sideband ?

Hi Guys
Andy, if you wish to join in the Net14 activities with just PSK-63 then by all
means do so but I stress this frequency is not for general QSOs. If you are
just running a PSK-63 program set your dial to 14.103MHz LSB and the PSK tone
to 1300Hz. If you are running an APRS program under
I've never heard of Net14 before and don't know how it differs from APRS in
general, but the best band for APRS activity (including using PSK63) 24/7 seems
to be 30m.
You need the software APRS Messenger which you can get from this Yahoo group:
We have been using PSK63 for APRS inside PSKmail from 2003 to 2005,
and we have dropped it. Reason was the long duration of the frames, which made
them
extremely vulnarable to qrm, qrn and other goodies.
We are now using PSK250 and PSK500R with a lot more success, also the pskmail
protocol has
Extensive testing of ROS on the air on UHF have now been concluded.
Unfortunately, ROS totally fails for UHF communications, in either 16
baud, or 1 baud variants, and using either the HF or EME channel.
Even with ROS metric readings between -1 dB and -8 dB (i.e. relatively
strong signals),
Thanks Juian, the Net14 instructions suggested 1800 Hz as an audio frequency
but I'll try 2100 and see if I detect any traffic. I do have APRS

There's a lot more to Olivia than being multi-tone MFSK.
A fairer comparison with a new mode such as ROS would be MFSK as the
features of Olivia that make it so very robust could (should) be added at a
later date.
To put it simply Olivia hunts for the best signal it can decode and has

I am aware of that, Simon.
However, Olivia is currently the most popular digital mode other than
PSK31 and RTTY, and the question was if ROS 16 baud was worth using
twice the bandwidth of Olivia. We hoped that

The question is whether a narrower mode would have done as good a job or even
better. To take up more than twice the bandwidth of even the widest Olivia mode
there has to be some benefit. In IARU region 1 only 10KHz is allocated to
narrow band digimodes so ROS should not be used at all on 30m.

If there were documentation on ROS then there would the possibility of

I don't think you can impute anything meaningful from one set of reports.
Normal QSB will make a difference of from several to many dB which can only be
averaged out over a period of time.
WSPR is much better IMO for this sort of thing. You can leave it running, go

Yes but at UHF there seems to not be enough spread to tolerate the
Doppler shift. If the frequencies were further apart, and were received
through a wider window, the Doppler would be tolerated better but at
what penalty in noise? I can think of a few ways to solve your problem

Keyboarding is in the Winmor TNC.
It has been added to the s/w in N3ZH_Software yahoo group Files section.
I suspect it won't be as good as Olivia in bad conditions.
