Packet/APRS

First get your Sound levels adjusted¬† “in the ballpark” for your sound card interface to the radio using Fldigi! Then you can be successful operating packet.

 

“Packet radio operates on the 2 Meters band or Very High Frequency (VHF) at a 145.05 MHz, , 144.91 MHz & 144.93 MHz frequencies, and are similar to the internet, but primarily text and at a much slower transfer rate of 1200 baud.” (From BARK packet page) Berryessa Amateur Radio Klub also has a Facebook page.

There is an active packet radio group in the Sacramento Valley and a network of Digipeaters called K-net.

It is not necessary to use a hardware TNC anymore to operate packet. A program running as a virtual TNC and a sound card interface to your radio will suffice.

Then you also need a terminal program to operate packet radio on your desktop. a good simple one is found further down on The UZ7HO page (easyterm39.zip.

APRS

Stands for Automatic Packet Reporting System. Yes it reports position, but a whole lot more!
