Re: Some reasons maybe why



Dave and group,

I noticed the same thing here.
Signals from ISS are down from PCSAT's whopping 2.5 watts according to the 
telemetry from PCSAT's beacon. (full sun)

I thought that ISS was running 1 watt vs. 10 watts.
I know when Mike had the school QSO with the Santa Barbara station,
Mike was 95% pass time copy, and up to S-9+40 in my mobile!
He had a fantastic signal! This QSO was after the new D-700 was hooked up, 
and sounded like Mike was on the Kenwood.

IF packet sounded like that, more stations would hear it.
I am not sure if it is the radio or antenna. It seems to be deaf too,
whereas it takes maybe 20 watts ERP to digi off. Could be attitude or 
antennas as Dave mentioned..
I have a Ringo Ranger vertical hooked up to a radio with open squelch
sitting on 145.800 (in QSL Mode)and I have only decoded 1 packet since ISS 
has been back on the air. Hmmmm...

I am uplinking ISS 100% of the time to the ARISS website, so if I hear you 
via RS0ISS-4, you should see something.

73, Scott
