Audio through VHF Astro-Tac

Post by wa8pyr »

All,

I've got a couple of VHF Astro-Tac (analog) receivers here which are hopping anxiously from foot to foot in hopes of being incorporated into my new and improved repeater.

Got it programmed to the proper frequency/PL settings, got the front end tuned to .2uV (yes, that's point two), the little LED lights up when a signal comes in from the signal generator, and audio comes through the speaker jack on the front just fine.

Problem is, I can't get audio to pass through to Line 1, Line 2 or the Wideband RX Audio line to save my life. I'm a big fan of flat audio throughout the repeater chain, and this is going into a voter anyway, so speaker audio just won't cut it.

I suspect a programming setting, but it could be any number of things. Anybody got any handy hints?

Thanks,

Do you have the pilot tone on the wire line connector?

No, I'm not using an Astro-Tac or Spectra-Tac voter, so just trying to pass straight audio.

I'm pretty convinced the issue is somewhere in programming, and I recall seeing somewhere that newer Motorola products only route audio to a particular point when certain signals/conditions are met.

I'm going with PL activation and hold-in, and have the wildcard set up to give an active high upon valid incoming signal, which is also working great. Just can't get that dang audio to either the wireline or wideband audio port.
