Mobile K2/100? with detached control head??

[Howard W. Ashcraft]

I am considering modifying my K2/100 for mobile operation.  Ideally, I
would detach the front panel and control board and mount them in the
dash or near the driver with the remaining transceiver pieces in the
rear of my SUV in a modified EC2.  The SUV radio/CD player has an
auxiliary input, so I will probably pipe the audio into the built-in to
provide sufficient audio for mobile ops.  ( I may need/want to build a
small pre-amp/audio out to match the impedance/level of the audio input
in the SUV.  Does anyone know what the standard level/impedance is for
an "AUX" connection?

Before sitting down and figuring how to accomplish this task, I thought
I would ask if anyone has undertaken a similar project and if there were
any unusual difficulties.  (The good/bad news is that I won't actually
undertake this project until a K3 arrives, so I have time to consider
how this should be accomplished....)

73,

Typically in audio applications you don't worry about impedance matching, an
aux input is typically a high Z (think input stage of op amps or similar)
and they are expecting a low output impedance from whatever you are feeding
it with. You should feed an aux input with line level audio.
