Problems with a failing USB connection to our 30m TNC are resolved, for now, with an ad hoc solution of rearranging where the USB ports plug into the Linux system.

Here is a video of our radio group passing field day bonus point messages off site using packet radio. Gear includes: Kenwood TS-2000 transceiver, but not using the internal TNC as it is not up to the task of regular packet radio use; SignaLink USB soundcard interface; Direwolf software TNC; N9TAX Slimjim J antenna; Outpost […]

Opportunity knocks The curators of the local Fauquier 145.730 MHz packet node¬†decommissioned their system on the very same hill we hope to rollout our version of the¬†Virginia Packet Network. The antenna and cavity filter are still in place. This makes our 2m packet frequency open for use with relative ease. With some lobbying efforts from […]

Direwolf – What’s not to like The more I learn about the various software demodulating algorithms in the amateur community, the more I like their commitment towards using correlation and other techniques to squeeze a few more good AX.25 frames out of the ether.¬† The Direwolf project appears to be one effort incorporating the lessons […]
