I am running Opera on 136 only. To run on 477 would require me to
stop monitoring WSPR2 to QSY the receiver, which I do not want to do.
I see, thanks for explaining that the speed and decoder is linked to
band. Now I understand.
I don't know if my spots will be uploaded. I have been asked to
enable this, but I do not see a setting to enable uploads.

Ok Paul,
Are you running 477 and 136 , or 136 only ?
The decoder mid band is set in the Configure >> Rig Panel , select
1500 or 2000, same panel, If your rx only , set ptt VOX , then its
inert ,
One of features , is the mode speed and decoder are linked to 'BAND' ,
stability requirements increase as the time extends, older versions
did have dual speeds for each band , but the latest version are
single speed, stability requirements increase with the longer modes ,
Afc is provided and no real advantage is gained from ultra stable
transmissions or repetitive same frequency cycles , [ other than a cross
check to decode frequency as validation for a correlation spot ]
Opera is designed to be run on normal 'ham' kit
Dual modes are provided for 477 and 136 'only', one-pass data decode
is provided for all bands , on 136 this functions to ~ -40 dB s/n
in 2.4 Khz b/w , after that , deep search [ correlation] detection against
call sign list is automatically engaged as a second chance, providing
additional -5 -6 db , same for the 477 Op8 band , first data decode ,
then detection against call list .
Example ,[ day time 477k] dual mode's , first spot , failed to decode ,
reported by second deep search , second spot full decode at -28 dB [
average] F 6% indicates 6% of the 256 data bits ,lost or at -3 dB
above the min decode level , the spots indicate which mode is reported
11:41 477 M0HGU de PA7EY Op8 Deep Search -32 dB in Amsterdam
12:00 477 M0HGU de PA7EY Op8 -28 dB F:6% in Amsterdam
Yes , spots are distributed to other users via the web , also a chat
function , call to call and broadcast mode , psk-map spots are also
unloaded directly , though , showing on the map is not as reliable as in
the past , the mode is listed in ADIF
