Tonight on the DEN I would like to take checkins using FLDIGI and the mode Olivia. Olivia is very robust, and has many "speeds" available.
With the wider phone BW of an FM repeater, we might play with something like Olivia 32/2000 (32 tones, 2000 Hz Bandwidth).
It sounds very elegant and musical.
Be patient since there is a slight time delay (sound vs. print on screen) using all of the Olivia modes. We'll stay centered at 1500 Hz.
We are expecting possible storms coming through Phila region in the late afternoon and early evening hours tonight,
so we may have to adjust plans based on local weather. When I hear thunder, I shut down.
For traffic, please consider a "severe weather flmsg" message.
We will likely switch to a faster mode like MFSK 128 for traffic and images.
Allstar is a voice over IP communication mode
based on the Asterisk PBX platform. An analog type transceiver
is connected to other Allstar nodes via the Internet. Doug,
WA3DSP, developed the code to run Allstar with an inexpensive
Raspberry PI. For more information

Messaging System and the Pa NBEMS Net meets every Sunday morning at
0800L using Fldigi. Barry, K3EUI, is the net manager. We
would like to see more participation from the DEN members.
