[Motorola] Questions re NKN-6099A Adapter Cable

[Geoff Fors]

There is only one version of PT 400.

The smaller pack set was PT 300, and PT 200 if the RF PA was not used.  They 
all use the same receiver as the HT 200 Handie Talkie.

The one using MX modules is the PX 300 and PX 300S and is vastly newer and 
different than a PT 400.  The PX 300 uses a PT 400 battery box and 
accessories.

It's been decades but there was originally a metering cable I used on PT 
400's that had an 11 pin female "octal" style socket on one end to mate with 
a conventional test set cable, and the other the DB connector for the PT400. 
The only thing you really need the metering cable for would be the RF PA. 
PT 300's have no metering sockets and you tune those up with a VTVM.
