[amsat-bb] D-STAR repeater problems in Copenhagen

7 Dec 2008


      Hi all,
During December and during the last large activity on 
the ISS, some of us here in Copenhagen have had problems 
with a D-STAR repeater on 145.7875 MHz.
Do any of you have a measurement of the spectrum of 
the D-STAR transmissions ?
The theoretic spectrum should be more than 60 dB down
on 145.800 MHz,but that does not seem to be the case.
Including doppler the downlink from ISS is 145.796 MHz, when 
it is going away from us to the East, which is the direction
of the repeater :-(
Personally I am just 6 km away from the repeater with 
no obstructions on the pass from it.
To avoid flames - no I have nothing against D-STAR :-)
