Hi Markus,

as explained to you in a private email, I totally agree with the complaints of Steinar.

Waiting your solution, I ask you:

- in a your past Email you wrote: "..seem to be sending incoherently, possibly because their oscillators or dividers are being restarted with every dash..." .
  Is compliant to your requests a signal generator (mine is a Marconi 2022 controlled by a GPS) plus a fast analog_switch plus the PA  ???
  (during OFF period the output of the generator is routed by another analog_switch to a 50 ohm load)

- Is your correlation scheme applicable to all OPERA modes ???
  (this is because I want make some tests in 28 and 144 MHz with extremely low power)

tanks again for your interesting work  ...

Hi Markus, sorry for not been able to answer before now.

This was great news!! As you know , I am not very found of jose soft,
but I will love to play with an open and well documented version.

By the way , what about using another name then Opera? The Norwegian
Opera Software ASA have registered "Opera" as their trademark and for
new users that is used to the "Opera browser" it is a little bit
confusing reading about a ham software also called opera, but this is no
big deal;)

The benefit is that these detections can be up to 10 to 12 dB more sensitive than the incoherent decoding in the original software.
