I programmed my TinyTrak4 using a laptop and USB->serial converter and
it worked for me.

The file you are uploading will be something.TT4.  I think
tracker644p.TT4 is the latest.

I found a later copy of TeraTerm Pro which works with XP & Vista at

You have to follow the instructions in the firmware manual --exactly--
or it wont work.  I had quite a few abortive attempts because of my
failures to do this.

-Make sure you set your com port to 19200
-Did you press lower case "b" within half a second of getting the ?
prompt to get it into bootloader mode.
-you should then get ">"
-then press s and send the file in binary mode.

After that you should be able to run the configuration program.

I found it easy to miss a step and get funny things on the screen.

I'm using my TinyTrak4 on 2m at the moment but want to try HF shortly.

today was that the cable from the TT4 to the radio suites either radio,
so that is a bonus in not having to have 2 cables.
