WinRPR: Saving Robust Packet from oblivion
The creator of Robust Packet has graciously ported a form of TNC code to Windows making Robust Packet available as a sound card mode.
TNC
Plug and pray Linux USB serial ports
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.
Passing ARRL Field Day messages the easy way with packet radio
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 … Read more
SCS Tracker in bad mood
VAPN has its first technical hiccup involving the SCS Tracker TNC getting into a strange state where it responds to connect requests with a short blurb and that’s it. Category: TNC – Severity: Block
Conquering Outpost Packet Message Manager
Outpost Packet Message Manager promises a familiar user interface to good ol’ packet BBS messages, but with a non-trivial learning curve in setup.
November 2016 status report
What’s been happening in the VAPN development. Topics: Test system up, 2nd Tracker, Rackmount PC, Donations, Organization.
SCS Tracker DSP TNC at 1200 baud
Our interaction with SCS engineers reaps an improvement in 1200 AFSK performance in their Tracker DSP Terminal Node Controller yielding one TNC with packet modes for DC to daylight.
2m rollout opportunity possibly Fall 2016
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 … Read more
Incorporating Direwolf into the VAPN design
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 … Read more
Ordering the Raspberry Pi and TNC-Pi for testing
Bought a Raspberry Pi and two TNC-PI TNCs for consideration as a hilltop remote node.
Introduction to Packet Radio
A well written tutorial about packet radio continues to educate the amateur radio community.
