[aprssig] Voice Alert

I guess I'm a bit confused.  Using voice alert, you have to send as well as receive the "tones".  Digi's shouldn't be using anything like that though and should hear regardless of PL's or CTCSS's etc...  
Am I missing something in Bill's comment here?  Not harassing you Bill, just confused on my end...

Ken, That would definitely do it.  There shouldn't be any reason for you
to send any CTCSS tones  on the dedicated APRS freq. 144.390.  (If that
is indeed what is happening).

It might indicate a problem with that one digipeater site also as it
should have filtered out those sub-audible tones before they arrived at
the packet modem.
