Just the system is not working, 3 tx sites and using non Trak timing, trying cnssys equipment and basically i have a big blond fold on, System Kinda works but still no where near being right,
i am ordering some new Spectracom clocks and 1 pps outputs. anyway i will see how it goes, just really after mots gps simulacst manual for astro systems, that i think might explain a bit more.

Well without a 1 pulse per second source at each site, its going to sound horrible. Are you using TeNSr channel banks, or what? Is your simulcast dual-mode or digital only?

If you don't have an HP or similar piece of audio test equipment, then you will not map your overlap for the three sites.

The wave forms have to match or your warble will continue.

The TenSr's are great for the job with proper GPS syncing along with T1 connections that have NO latency.

CoM
If the lights are out when you leave the station and then come on the second you key up, you know you have enough power.
