Ham Station details

These pages are a mirror of the original pages found on http://www.sv1cec.ampr.org, which -unfortunately- is only accessible to radio amateurs (systems in the 44.xxx.xxx.xxx address space, or the .ampr.org domain). As a result, the description which follows, shows the system which serves the wireless www server in the Athens area. By reading this page, you will be informed about some of the technologies used by an amateur radio network station.

System Configuration

SV1CEC TCP/IP network is a LAN consisting of several servers, which connect to Internet via a wireless link. This LAN provides an experimental service to the TCP/IP network of Athens, called ATHNet which serves about 50 radio amateurs. Services provided are telnet, ftp, smtp, pop, finger, tty, gopher, www and callbook server. Systems configuration follows.

Computers

*** Router ***

- 386SX, 25MHz, 2MB RAM, 200MB Disk

- TCP/IP : JNOS ver. 1x114

*** WWW and FTP Server ***

- Sun SPARCstation 4, 32 MB RAM, 1 GB disk

- Solaris 2.5 Operating Environment

- WWW server and WU-FTP anonymous FTP server

***Gopher Server ***

- IBM PS/2 Model 30, 8086 2 MB RAM, 20MB disk

- TCP/IP : JNOS 1x114, with Selcuk Oztourk Gopher extensions

(A Sun and an 8086 on the same network!!!)

*** Client ***

- Pentium, 133 MHz, 32MB RAM, 1 GB Disk

- TCP/IP : Windows95 Networking

- Used mainly for HTML editing, etc.

*** Client ***

- 486, 66 MHz, 8MB RAM, 100MB Disk

- TCP/IP : JNOS ver. 1.10M, PC/TCP etc

- Used mainly for ham applications, like contact logging etc.

*** Client ***

- 486DX, 80MHz, 256KB cache, 16MB RAM, 1.4 GB Disk

- TCP/IP : PC/TCP Ver. 2.3, Trumpet Winsockets etc

- Used mainly for Office Automation applications

*** Portable Client ***

- Compaq Contura Aero 4/33C

- 80486SX/ 33 MHz, MS-DOS 6.20, 8MB RAM, 250 MB Disk (portable)

- TCP/IP : WINSOCK and Windows-based client tools

All servers and clients are connected together using Ethernet cards and TCP/IP. The portable PC can also be connected to the ethernet network, using TCP/IP.

Modems

- PK-232MBXs, KPC-9612, BAYCOMs

These modems are similar to normal telephone modems, but they do not use a telephone line to connect to each other. Instead, they use a radio.

Radios

- Icom IC-229E - Icom IC-820H

- Icom IC-24ET - Kenwood TS-450 SAT

The above hardware is connected in the following manner :
