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)


We are going to continue talking about Packet during the 2nd part of the DEN. Be sure to look at the information on the modem settings below. The change of the TX Delay should help sending packets through the repeater. Change the delay from 250 to 1000 msec. Thanks W3AFV for pointing this out.

First part will be Fldigi check in using Thor 22. Then traffic using MFSK128 or any of the faster modes you would want to experiment with. Don't worry about failures. "Break, Fix, Learn" :-)

Hopefully everyone got the information about the new Local Weather custom form. It would be fun if everyone tried to send it during traffic. If you have trouble with it let me know.

For the second part of the DEN I would like to revisit Packet. I've heard some interest about it on the repeater. Fldigi is good for communications 1 to many but Packet has the capability of messaging store and forward. You can set up a BBS in an area and store messages for later retrieval. Remember the old dial-up Computer Bulletin Boards :-) I know the Internet is faster but this is radio and it's fun to play with it.

Okay, if you have a TNC then you're probably already set up for Packet. These days you don't need a TNC just the same equipment you're using for Fldigi. I use a Signalink using a program called Sound Modem. You can download it from here: and about 3/4 of the way down click on to download. Unzip the file and you should see a folder called soundmodem105 with a program called soundmodem in the folder. You can copy this folder on your C: drive. Now go to the folder and create a shortcut to the program. Make sure that your Signalink is connected and start soundmodem. On the main screen click Settings, Devices. Use the following as an example:

Click OK. Then Settings, Modem and use this to set it up.

Now for a simple terminal program. On the same website about 1/2 way down look for download and unzip. This will give you a folder called easyterm46 which includes the program called Term. The easyterm46 folder can me copied into the soundmodem105 on your C: drive. Create a shortcut to the Term program and start this program. In the Settings windows enter your callsign. Now you're ready for the DEN. I will set up a BBS here and step everyone through connecting and reading messages. Any questions let me know. See you all 1/14/2020.

For the advanced folks that can't wait to play. The KB3BUX-11 is a BBS operated by the Bucks County ARES/RACES group. In the Easy Term program enter KB3BUX-11 for the BBS and W3SK for the digipeater. The frequency is 145.610 Mhz simplex.

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.
