Batboard

I just bought a suitcase repeater, P43SXS3180 which mostly seems to work.

Six of the eight channels have TX and I've used a meter to get their VHF frequencies listed out. But how to work out the inputs and their PL's? Is there a way to read this thing?

The DVP works, which is nice albeit unusable in the US.

The speaker mike keys the TX and the speaker works but there is no audio passed when I speak into it, got any idea why?

As there is a PL switch I assume at least one of the channels had PL enabled.

I'm missing the little VHF Antenna Specialists antenna that fit inside the lid, anyone got one to sell?

Appreciate any pointers.

Cheers Nigel

No, you have to take the unit apart, these units are usually only one PL or just carrier squelch. As far as inputs, look on the bottom of the unit under the access panel, they might be listed, or you will have to look at the top of each RX TCXO. The board closest to you when you flip it over. Now if the unit is former Federal Gov, they don't put the frequencies on them, they put the oscillator frequency on them, you will have to do some figuring, if I remember correctly, multiply by 3 and add 21.4 mhz to get the actual frequency.

I thought SXS was the synthesized version?

The model number of the suitcase repeater doesn't totally follow Motorola standards. I have never seen a synthesized MX series style suitcase, but I have modified mine. The biggest problem I ran into is the fact that the frequency select was backwards. I had to program channel 8 as channel 1, channel 7 as 2 and so on. Other wise the unit performs flawlessly. The first thing I would do is open the unit up and remove the memory battery from the main board, had a few of them destroy the main circuit board by leaking all over it. Some more info
