[TheList] Pager Decoding

Tue Jan 12 16:09:43 AEDT 2021

Whats the hardware setup you are using Brendan? Also internal/external 
Antenna? I just wonder if by using an outdoor Antenna im receiving too 
many towers and they are out of sync and causing corrupted data - thus 
the slightly lower decode rate?
