Can anyone provide the nominal impedance of a chatterbox headset speaker v. a stilo headset (or built in) speaker?

I can't answer that question but I do have a Stilo with rally electronics and I plug it into a Chatterbox TP2 with a suitable (passive) cable and it works just fine talking to another person who is using a regular student headset. Not sure if that's useful or not but just in case...

After some research and measurements I can confirm that the Stilo electronics has significantly lower impedance than Chatterbox. It will 'work' as I and boxer-11 have experienced, but is not optimal.
There are level and mismatch issues.
