Kurt,
If I am correct your system doesn't acquire satellites by looking at specific transponders but simply looks for energy across the frequency band output by the LNB. The original cheap satellite meters worked using the same principle. On yours you set the elevation and it pans until it finds energy and then stops when it detects something. To change satellites you probably have to change elevation. As long as the boat doesn't rock too much it probably works fine. You would be immune to the change DISH made. Looking at the AzTrax you could convert to the DISHPro LNBF (the newer technology) with the DPP33/44 switch. PM me and I will describe how to do it.
The older LNBs work with any signal modulation. They are kind of like a broadband radio receiver, anything they hear between 12.2 to 12.7 GHz they convert to 950 to 2150 MHz and send it down the cable to the receiver. The tracking terminal splits off some of the signal and uses that to determine if it is on a satellite. The AzTrack is looking for energy and the KVH/Intellian and others are looking for a specific transponder frequency and modulation format. Change the modulation format and they become stupid. The reason for the KVH comment on the eastern arc was probably because that arc has been 8PSK for quite a while.
Raymarine was fairly late to the TV game so I suspect they built in the capability to adjust satellite modulation like KVH did in their later units. They would still have to send all their customers new firmware or have them make changes in the tracking configuration.
