Hi.
Nice tutorial Sir, well done.
You might want to tell WSJTx, that the mode is USB, and to "Fake
It" for Split.
That moves the rig's TX frequency when needed, so as to keep the
TX audio frequency in the higher part of the rigs passband,
letting it's filters remove any audio harmonics.
Such things are plaguing 20m in particular, spreading/splattering
FT8 harmonic signals above (and below!) the FT8 sweetspot,
wrecking other mode users.?? (There are other modes than FT8!)
Well worth keeping the output power down if you ever run any PSK
mode, to at most a 1/4 of what the rig is capable of, again to
prevent splatter and intermod' signals spreading either side of
your intended transmit frequency.? With other modes (MFSK like)
it's usually a disipation limit in the rigs PA that needs care
taking over.
Qpwgraph.? I personally have a love/hate relationship with that?(v0.3.9)
as despite following all the instructions, and saving the setup,
each time I launch it and reload the setup, the patchbay display
is a still mess of tangled green spaghetti.? It is also very
difficult to differentiate between any of several identical audio
interfaces, renaming is not supported.? (It also doesn¡¯t exit
cleanly, if you launch it from a command line, when it exits, you
have to use ctl+c to recover the command line!.)
For a simple installation on a Pi, I'm not sure it's a "needed"
feature anyway.
I just use Pavuctl to set the levels, and the app's own controls
to select the device(s), but once setup, exit it to save on CPU
cycles.
Enjoy all the available digimodes, Olivia in particular can give
you a "conversational" QSO over great distances, where you can
hardly hear or see the signals.? Don't forget to use the TxID and
RxID facilities in Fldigi if you use the not so common modes.
JS8Call too, is very good.? (Again, mode is USB, and enable "Fake
It" for Split, so the heartbeat feature works "cleanly".)
You have plenty of tools in the box to play with...
Running LMDE 6 here on an intel platform.? Three radio's and no
less than 5 Audio I/O devices!
