Outpost and the Tracker
The latest version of Outpost PMM directly supports the use of the SCS DPS Tracker TNC. Set yours up using the steps in this article.
Tracker
SCS Tracker RPR spurious audio emissions fixed
The 1.7k version of the SCS Tracker firmware appears to address the spurious signals above and below the primary signal.
Sabrent 13 port USB 2.0 Hub
We review and test a USB hub for attaching multiple SCS Tracker TNCs to our node/switch computer.
Audio spur above RPR spectrum
The SCS Tracker DSP TNC works very well, but we noticed some additional energy transmitted above and below the primary Robust Packet 500 Hz bandwidth.
FRACK and the SCS Tracker DSP TNC manual
Instruction manuals for electrical devices often take last place in priorities when time comes to actually write them. Such is the case with the SCS Tracker DSP 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.
HF packet system or bust
Waiting for a spot on the mountain shouldn’t prevent adding tremendously useful HF access to the VAPN system so that’s exactly what we are going to do in the lowlands.
September 2017 status report
Negotiations for hill top space continue while we consider adding HF to the current 2m prototype.
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
Going all in for the SCS Tracker DSP TNC
The SCS Tracker DSP TNC wins its way into the overall design of the VAPN.
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.
