Hardware projects
Not all the ham equipment can be bought on the market. Especially high speed packet radio equipment, RTX's for over 1.3 GHz, ATV equipment, etc...
Fortenatelly, hams in S5 are inventive enough to project and produce their own solutions, which are often on higher quality level than
commercial versions available (if available at all).
Here we present just a few projects from the hudge selection - but new projects will be added constantly.
To start with packet radio, you need at least
TCM 1200 bps "BayCom" modem.
You can than upgrade to
TNC-2, clone of the basic TNC - Terminal Node Controller, built around Zilog Z80CPU and, with
manchester modem suitable for speeds up to 76800 bps.
Alternative to TNC2 is
USCC (ISA) card with two modems on it, one slow 1200 bps AFSK modem and one medium speed 2400 - 76800 bps manchester modem.
To be able to use medium speed (up to 76800 bps) packet radio network in Slovenia, you will need
WBFM Wide Band FM RTX.
If you are eager for even higher speeds, than you wil have to use
PSK RTX, with speed set at 1.2288 Mbps and new
SCC-DMA (ISA) card with one medium speed (up to 76800 bps) and one high speed (1.2288 Mpbs) channel.
Of course, our network needs diferent kind of equipment too. So, first replacement for small TheNet node (digipiter) was
Mini SuperVozelj, shrank version of his big brother,
SuperVozelj network node computer, home made system based on 68010/68320 processor with up to 10 channels of diferent
speeds from 1200 bps up to 1.2288 Mbps.
Ad-on for SuperVozelj is
Frame Grabber, an interface for CCD camera.
Not every project is for digital communication; Matjaz, S53MV, has developed some very interesting projects.
There are
1296, 2304, 5760MHz SSB/CW RTX and
3cm SSB/CW RTX.
