Getting the Packrat 232 mbx to communicate

Hi All,

To progress a bit with the members who have a packrat 232 mbx I did the following:


I got hold of a RS232 to 9 pin to usb to the pc, either jaycar/ebay ect.

I made up a patch lead form the Packrat to the transceiver into a packet port on my radio.


I downloaded the puTTy and RMS Express programs, They are free and only take a couple of minute


-          puTTy program: is to get the Packrat set up and communicating with the PC and talking to  each other

-          Open the puTTy program and a configuration box will open

-          Select serial port and click open.

-          Once you get the command prompt on the putty program press shift ***(star) a few times and it will open up the software/version of the PK232

-          - Then type in I am, Then it will come up as I am pk232 or just 232.

-          - Then type in I am again with  (your call sign) eg: I am VK6TTF and press enter. It should then come up with your call sign. Then you know it is working to the pc, YAY



RMS program:  Set up with your call sign and station details and set up peer to peer until we get more organised

If you go into and click open session another window will open up.

Go into set up drop down box and open TNC setup.

In this box you need to put in what serial port you are using : ie; COM5 etc?? And set on Pactor 1 for HF.


Once you are this far contact some other members to see if its all working ……Then when you see it working a feeling of joy will overcome you as you have succeeded in the first stage of learning.


The sound-card interface I am still working on and will post what I am doing. Cheers everyone and I hope this helps out. I can help you if required.
