Re: ISS UtIquette

ALERT:  We are beginning to hear a lot of packet on UO-14 (uplink
145.875).  Two possible causes related to ISS are:

1)  Possibly a combination of Doppler, AFC and rig offsets making
UO-14 actually hear packets being uplinked to ISS on 145.990.  Someone
could test this hypothisis...  At 12 Khz separation, powerful packets will
probably be heard but not decoded...

2)  Rigs being used for ISS and then QSYing to monitor UO-14 and
forgetting to turn their PACKET off.  

Both of these are solved by adherence to rule number 2 in the ISS
