[amsat-bb] NO-84 questions

I was not on NO-84 today, but there may have been a 10 m north/south 
band opening.  I do not think only 30w will turn on the FM transmitter 
from North America. During good band openings, I have seen LU and PY 
stations turn on the satellite.  If what you saw were terrestrial 
stations, the traces should have been skewed, probably at different rates.

I use NO-84 regularly, it takes 80-100 watts into a 1/2 wave vertical to 
keep the FM transmitter turned on.  The downlink signal is strong and EZ 
copy, but however, when noise is high on 10 meters, it re-transmits this 
noise onto the FM downlink, making for hard copy.


2315Z pass.

I could see someone in the passband, but it showed as 6 traces rather than
one.  Does that mean the transponder was overdriven with PSK?

I attempted to see if I could get through and at least see my downlink, but
no luck.  I figured even without the Doppler-compensated software, I should
see my signal..30 watts to an off-center-fed dipole at 56 feet.

Thoughts/suggestions welcome.
