Ok Roger
Yes all the 'ros' modes are
live keyboard chat modes.
One point is, ros is not a -time
locked- mode , so no need for a live web connection
handy for remote monitoring !
Yes I have seen mf-1 decoding when wspr had stopped ,
but 500 is tricky with qsb etc , that
was during the day via the delft web-sdr, but
as of yet I cannot manage a decode via tweant or delft
on 500 , even though a PA stn was showing -17db on wspr ,
as was Rik round the same time
will be interesting to see how
the ground and 137 pans out ?
there is a mf-1 audio test
file on the ros web site , with text message in
mf-1 at -33 dB
Ive sent some notes direct
with web-links .. should be a starting point

Hi Graham,
Not tried MF-1 yet Graham but I'm interested in
trying some new weak signal modes as long as they don't require much effort to
set up and run: I'm no PC genius so it needs to be easy! Do you believe
that this is the case with this mode yet? Maybe you could advise me how to set
up and run this.
BTW, -33dB S/N for 100% decode sounds like more
than 3-4dB better than WSPR, suggesting it would be a very useful mode for my
kind of tiny/simple/QRPp set-up - and it supports QSOs I think?
Did you
like the state-of the-art heatsink on the 136kHz TX transverter? Only had a
couple of croc-clips handy but this seems to be enough to keep the IRF510 PA
from getting too warm. Yes, transverting down from 10MHz band with the
136kHz transverter and from 28MHz with the one done last year for
500kHz.

Interesting set up Roger,
If G3XDV could 'see' your signal for
qrss3 , its quite possible that MF-1 would of given a
full decode ?
(assuming your transverting from hf
for wspr?)
s/n floor is round -33 db for 100%
decode falling to 90% at -34 , -35>-36 are tending to
'random'

Subject: LF: My first 137kHz WSPR report
Just got my first 137.5kHz WSPR report from G6ALB in the next
village 3km away. Andrew has a far from optimised set-up. So, in the last week
I have been copied by 3 different stations:
G3XDV partial ID on QRSS3 at 62km,
G3XIZ -
full ID on QRSS3 at 48km
G6ALB - full ID on WSPR at
3km
Although this may not sound impressive, to me it's a very
encouraging start considering the station, micropower and 20m spaced earth
electrode "antenna". A picture of the QRSS3 beacon and the TX
transverter used for WSPR is attached. 73s Roger G3XBM --
