We have still the last working OP2
qso mode , which can send ' I have two cats'
But the decode s/n is -20 dB ,
ROS-MF-2 is round -26 dB -28dB about
the same
as wspr-2 , but a full free running
data mode
At speeds less than 1 baud ,
would any one use such a mode , there was
a ROS 0.1 Baud
7/8 db lower , but very very slow
! ..
In the start , was the problem of
translating audio to rf on 136/500 ,
but now that
seems to be much less of a problem

Dear LF enthusiasts!
my opinion is not very original in
English - in Russian I would write A4+++ :-)
"CQ R7NT K"
QRSS20
- 28' 40'" simple TX, visual decode, subjective report, random
time, QSO mode....
DFCW20 - 11' 4" little more
complicated TX, visual decode, subjective report, random time,
QSO mode....
"any call ++"
Qp32 - 32' simple TX,
software based decode/report, random time, no QSO mode....
WSPR-15
- 15' little more complicated TX, software based decode/report,
00', 15', 30', 45' times to start, no QSO mode........
QRSS20
~~=DFCW20 ~~=OP32 ~~=WSPR-15
Comparing OP32 and WSPR-15
(OP8/WSPR-2) is equally as comparing QRSS20 and DFCW20 (QRSS3/
DFCW3)
I personally like DFCW, JT9-5..10 more.... but I have the little
choise now....
...maybe WOLF agn?
