[Kenwood] TS-930S Mic Impedance

[Fortra]

Hi Daniel,

in service manual, sheet signal unit X-57-1000-11 for kenwood's ser.nr. 
208xxxx-309xxxx, there are two connectors J16 for low impedance mic. and J17 
for high impedance mike.
On sheet signal unit X-57-1000-11 ser.nr. from 310xxx there is only one mike 
connector, i.e. J17. Check your s/n and that is it ......
