Digital Modes in Coshocton

On this page on our website we devote to the digital modes. Here we explain some of the current digital modes that memebers are using for ARES (emergency services), and for everyday contacts. Some of the many modes include: PSK-31, RTTY, Olivia 8-500, MT63, APRS, (and even CW {the very first digital mode}).

We will try to list links and info. to help out the digital ham.

Coshocton Digital Net

Join us on the 147.045 Repeater every Sunday to experiment and learn about the digital modes. The net meets at about 8:20PM local (right after the voice CCARA Net. The net uses both voice and digital modes (particularly using the FLdigi application.)

On the 4th Sunday of the month we use HF frequencies for digital, and with voice still on the 045 repeater during that net.

On one of our nets, Shawn KE8KMM re-sent this slow scan pix he received on a hand held transmitted by the International Space Station.

How to Configure FLDIGI

Warren WX8OH has found a very good set of tutorials on setting up and using fldigi and flmsg. It is by Rick Frost K4REF. He does a very complete job of guiding you through the set up and operation of this digital platform. They are found on youtube, and the one on configuration is found Here. You can also search youtube for Rick's videos by his callsign, K4REF.

These videos are helpful even if you have been using fldigi for awhile.
