I have a home brew repeater that does not properly transmitt PL. It has a converted 800 maxtrac for recieve, Spectra 900 for a transmitter, duplexer, and controller.

I use 131.8 pl and also have a set up for 343 dpl. The maxtrac opens up and recieves, puts the spectra in transmitt, but it does not open up remote radios (everything sounds fine if you turn the monitor "on" on the remote radios.) Fails the same with pl or dpl. (doesn't seem to transmitt pl or dpl.)

I assume it may be the pin setting in the maxtrac for filtered audio or flat audio in the maxtrac reciever. I think it it is passing the pl trough the controller and mixing it into the audio for the spectra....I have no test equipment to see what the pl output looks like from the spectra.

I thought it may be the spectra tunning, I swaped it out with another radio and got the same results.

What should I set the maxtrac to? Flat or filtered? I do use the ctcss trigger line.

Any other things to test?

I will try friday to do a transmitt from the spectra with a mobile mic and bypass the controller.

Hacked Spectras are notorious for not transmitting pl. You can only modify the original archive
and push it back into the radio. If you read it, make changes, then write it you will not TX pl anymore. This should be covered in the archives. After properly doing the moflag hacks for my radio this problem was resolved plus it added several features such as MPL.

no hacks other than the software to allow the out of band programming. VCO was converted before I got it....

What version RSS are you using?

Maxtracs do pass PL thru, so if your controller doesn't filter that, you may have to.
What usually happens though, is it will go in and out of phase and the end user will have thier radio open and close.
What happens if you use the local mic on the spectra?

Trying the local mic friday, I'll check on the rss version.

I have seen quite a few spectras long ago pl/dpl encoders crap out(decoder worked fine) and have to be sent back to mother moto to be repaired. I think at the time it was a known problem but thats all I can remember about it. The grey matter doesnt work as good as it used to.....
