PocketDigi will run most digital modes (RTTY, PSK31, MFSK, Olivia ...) on any
Windows desktop or laptop with 150MHz CPU. It is efficient enough to decode
PSK31 on 75 MHz Pentium and show waterfall.

While addressing an ARRL LOTW uploading issue with JT65 modes, I began to be
intrigued about B and C that I have never tried . Here is an old 2004
explanation from Joe Taylor. Interesting ,at that time , that he was

We are operating as VE5XZ on field day, (3A) using as many digital modes as
possible. Ops mostly 20/80m and will be active for the entire

Look forward to workin y'all

I have been the digital ringer for a few clubs in the past few years,
bringing lots of gear and demonstrating how digital modes work. This year I am
not going to a highly competitive club, will do some casual CW for a local club
and may do some really LOW tech digital modes operations.
I use an internal sound card for ham operations and an external sound device ,
in the form of USB speakers, for routine PC/Internet work including DX
announcements via Spotcollector. This works well except that every know and
again ham applications that have been working well via the internal
Andy,
I have also found that Windows will reassign USB ports if anything is
plugged in or unplugged. My solution was to set the default sound system
to the onboard system and use USB for the ham devices, such as the
SignaLink USB. The problem is especially troublesome when I plug my

AX25 allows several stations to operate within a bit of spectrum wide enough
for one. For example, up to a dozen Q15x25 stations can operate within one
1k to 3k ( depending on how you scale the modems ) slice of spectrum.
ARQ modes that do not operate under AX25 are incapable of this, and so
I had simmilar issues and found that I need to power down and reboot if I
wish to swap out USB devices. When hot swaped it gave me hell. Now I make a
point to make connections on USB devices with system off so it auto detects
and remains with proper settings of my desire.
