Re: LF: Re: [rsgb_lf_group] Re: 0p-32 correlation results online

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  ...
