We have still  the  last  working  = OP2  =20 qso  mode , which  can  send   ' I have two = cats' =20
But  the  decode   s/n is   -20 dB ,=20 ROS-MF-2   is  round  -26 dB  -28dB   = about=20 the  same

Dear LF enthusiasts!
my opinion is not very original = in=20 English - in Russian I would write A4+++ :-)

"CQ R7NT = K"
QRSS20=20  -  28' 40'"  simple TX, visual decode, subjective = report, random=20 time, QSO mode....
DFCW20  - 11' 4"      little = more=20 complicated TX, visual decode, subjective report, random = time,=20 QSO mode....

"any call ++"
Qp32  - 32'   =  simple TX,=20 software based decode/report, random time, no QSO = mode....
WSPR-15=20 - 15'  little more complicated TX, software = based decode/report,=20 00', 15', 30', 45' times to start, no QSO = mode........

QRSS20=20 ~~=3DDFCW20 ~~=3DOP32 ~~=3DWSPR-15

Comparing OP32 = and WSPR-15=20 (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=20 choise now....
...maybe WOLF agn?
