- Packet Radio Monitor v1.00
-
- To monitor packet radio traffic you need:
- 1. Radio receiver.
- 2. HamComm (or similar) interface.
- 3. This program
- 4. IBM PC/AT compatible - a fast one...
-
- To receive 1200 bps VHF packet:
- - tune the VHF receiver to a packet frequency in FM mode
- - connect HamComm interface to receiver audio
- and PC's COM 1 or 2 on the other side.
- - start PKTMON
- - select COM, mode (try 2 or 3), log file (CR for screen output)
- - watch for packets...
-
- To receive 300 HF packet:
- - Tune the HF receiver to a packet frequency (e.g. 14097 kHz)
- It is recomended that you use CW narrow filter
- (700 Hz center, 500 Hz width)
- - connect HamComm interface, etc.
- - Start SPECTRUM, select COM port
- - _Precisely_ tune the receiver such that packet tones
- are at 600 and 800 Hz.
- You may try as well 800 & 1000, 1000 & 1200, etc.
- - start PKTMON
- - select COM port, mode 1, log file,
- - watch for packets...
-
- Notes:
-
- The program should terminates when you press ENTER.
- If it does not that is an indication that your PC is too slow...
- Disconnect the audio and it will terminate.
-
- What to do if your PC is slow indeed ? Try to use squelch
- in FM mode to limit the amount of data your PC has to process.
- This often helps.

-
- PKTMON was tested on a 386SX/20MHz machine.
-
- PKTMON is written in Turbo Pascal v6.0
- with some parts in Pascal's built-in assembler.
-
- PKTMON program is free for non-comercial use.

- In preparation:
- - HF FAX with HamComm interface
- - Packet Radio Collector - reconstructs data flow between
- packet stations.
-
- In there any interest in these ?
