[Motorola] MRS2000 Questions...

[KB0NLY]

Oops, typo on my part!!

It has the station control, line driver, time out timer, F1 PL control 
module, four frequency control module, multi pl encoder, and of course the 
pl board and R1 Audio board.

The four frequency module was pulled and a jumper installed to enable 
channel 1 on the exciter, the way it was setup was with a single receive 
channel and a 146.2 tone reed in the PL board, and then the four channel 
board and multi pl board selected channel 1 in the exciter with four 
different pl tones, there was only 1 channel element installed, but four 
reeds in the multi pl board.

I pulled the multi pl board because i was told the TRN5073A PL Board i have 
is a duplex capable board, it can encode and decode at the same time.  And i 
got it to decode just fine again but i can't get it to encode.  And as 
mentioned i can't get it to provide receive audio to the test set speaker 
when its also transmitting.

Also, no squelch gate module, its being wired to an external controller 
instead and works just fine that way.  The only problem is no pl encode and 
no local speaker audio.

Thanks and 73,

Scott
