[Lowfer] I need some listener reports

[John Andrews]

Andy,

You may have misunderstood my response -- it had nothing to do with 
QRSS, as I presumed that you were keying at normal speeds. Your 
available "audience" will be pretty limited if they must listen in AM 
mode. If someone chooses to copy it in CW mode by tuning into one 
sideband, then they'll be trying to copy a 25 mw signal. That has 
nothing to do with computers, just ears. Unless you have some local need 
for an AM signal, you could improve your chances for reception by just 
keying the carrier. Just a thought...
