Considering the success that Pactor 2 has had, with what is one of the
more bandwidth conserving modes available with very good throughput and
yet only a 500 Hz bandwidth, this may be a target to meet by
developing a similar sound card protocol for emergency use. It does not
need to be the

Hi Patrick,
While you might get a lot of different opinions on what is needed for
public service/emergency communications, absolute accuracy is what many
of us consider to be mandatory. And because you are often going to be
operating under less than ideal conditions and locations, having a

Hello all,
I was reading the general specifications of Pactor and I note a curious feature.
The first mode of Pactor 3, with 2 carriers (in BPSK) specifies a crest factor
of 1.9 dB (ratio of 1.55).
Pactor 2 specifies a crest factor of 1.45 (in ratio)...1.6 dB
Meanwhile, Pactor 2 applies a root
