New subject: Making Packet Node with Pi ?

2 Mar 2016

High speed packet radio collapsed at 9.6 kbps because hams were no longer
able to hack modems into surplus land mobile radios.  For the first time,
one needed full channel equalization and plug and pray no longer worked.
That was pretty much the end of packet radio circa mid 1990's.  The only
thing that survived was APRS which is based on cheap land mobile radios, PIC
microcontrollers, and AX25/UI.

According to the TNC-X website, John Hansen claims to be working on a 9K6
modem but that was quite a few years back and nothing has been heard since.
I'd LOVE a 9K6+++ modem but they just don;t seem to be available.

I've looked at quite a few of the old designs that came out of German and
Slovenia back in the late 90's and early 2K's. They are either no longer
available, require an SCC card to provide clocks etc, have no driver support
any more or require firmware which is unavailable.

Whilst the soundcard road is somewhat acceptable, a hardware modem can't be
beat..
