Opps , too late in the day , or
not enough cake may be ? Uk spelling may
be !
The tx qrg is 8270 Hz , the
Opera OP4H is 8900/8925 , so that
is a increase in frequency of 700 Hz ,
so should have sight positive affect on gain ?
?
Yes I think SP can be used for this qsy
, but as to the affect on s/n I dont know

Going down to 8910 Hz means another
reduction of the antenna efficiency and it is quite an effort to move the
resonance of the antenna. Not a 5 minute job, maybe not even a 5 hour job! It is
better to shift the frequency range to the desired TX frequency. This can be
done in SpecLab of course. But actually it should be possible to add this
feature in the software itselfe, i.e. in OP4H.

Is it possible you could try running the
audio version of Opera OP4H ( 4 hour) ? as
of yet , there have only been garden path
tests , never with any high power !
The decoder pass band is 8900
Hz to 8925 Hz , making round
8910 mid band , there is no way to alter
this , in the this mode the software uses the
sound card as SDR , tx/rx , but also
can on-off key with the com port
drive ,
This is 700 Hz hf of your qrg , would
this be a problem with the Ae tune ?

even get the RX warmed up. :-)
Hope all is well soon.
