[Kenwood] TS950SDX dead

[Steve London]

Make sure the DSP unit (the unit that hangs from the bottom) is plugged in, and 
there is no intermittency in the connector that plugs the DSP unit into the rest 
of the radio. The way to check for this is to switch to the sub RX. If the sub 
RX works, than the DSP unit has a bad wire in the connector.

Without the rest of the radio, did the workshop have any way to test their 
CP1-CP4 repair ?
