The PMRC Digital Education Net

PMRC repeater: 147.030 PL 91

A voice and data net to discuss digital modes

Every Tuesday evening at 1900 (7:00 PM)

Agenda  DEN   Jan 15

7 pm - 7: 45 pm  FLDIGI  (no mic) checkin with traffic  FLMSG/FLAMP
           Mode will be a  PSK  mode, and a TxID sent by net control.
           Always keep your RxID  on during the net. Turn SQUELCH  off.

7:45  - I will do a   "Guess that mode" Challenge  by turning off TxID
          Can you now identify a digi mode just by its sound?
          The  PSK  modes are pretty easy to ID by their sounds (warble)
          The  FSK modes always play one tone at a time, different pitch,
           and are nearly Constant amplitude: 
                    MFSK, Olivia, Thor, Domino, RTTY
           Olivia always starts with a   "Low-tone, High-tone"  (Boo/Beep)
           MFSK plays the low-tone first, then that sets the "scale".

8:00 pm  Those ops that use  CAT control in your shack, please present a short description of what you have, why you like it, and how your rig can be completely controlled by your computer.

I can talk about  CI-V  Icom rig control techniques.  The Rigblaster Advantage that I have offers not only an external USB sound card, but  offers separate ports for CW keying, FSK  RTTY keying, and  also a rig control (PTT) thru a virtual com port. I can actually sit at my keyboard and do everything with the radio in another room:  change bands, change modes, change filters, etc.  In fact, with additional software, I can operate my radio from anywhere in the world with an internet connection.  Several PhilMont members do this already (like from the beaches in Florida).

Also....  please report if you operated any of the digi modes during the Jan 5/6  ARRL  RTTY Roundup.  I managed to get at least one digi mode qso on 80/40/20/10/6 meters, with about half the contacts with FT8.
FT8  was a super mode for short confirmation qso.
I had zero QRM although the bands of FT8 were bursting with signals.


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.

Thanks to Doug and the Philmont club for setting this up.


If anyone is interested in HF NBEMS nets there is a group called Pa NBEMS Net

To join the group click here: PA NBEMS

NBEMS stands for Narrow Band Emergency Messaging System.

The Pa NBEMS Net meets every Sunday morning at 0800L using Fldigi at 3.583
Barry, K3EUI, is the net manager.

We would like to see more participation from the DEN members.
