[aprssig] Multiple TNC's connected to one radio

 I would like to connect 2 tnc's to one radio. One would be transmitt/recieve and the other recieve only. This would be to test the decoding of a couple different tnc's. Am I likely to run into any problems connecting the speaker jack audio into 2 tnc's? Would the additional load cause me to have to readjust the audio level when I connect/disconnect the second tnc? My thoughts are since the speaker jack audio is low impedance (8 ohm) and the tnc input is much higher (hopefully) is that it will have little to no effect. 
Just thought I'd ask before wasting my time making a cable.
