The dish is switched from satellite to satellite by the same motor. The receviers are switched from one to the other by usng the TV inputs. The AZ is on HDMI4 and the the Quali is on componant1. I switch back to the receivers using the TV inputs. When I leave the Quali and then come back it has a dark screen and says no signal. After a few seconds the signal will pop on. When I leave the AZ and then come back the image that I left is froze on the video. That's when I either have to change channels or reboot.
Kevin, what you say makes sense, but it doesn't apply here because the Motorola 922 runs the dish motor. The AZ and Quali have nothing to do with the operation of the dish.
Also, for some reason since I brought this up it does not seem to be doing it now. When I go back to the origonal channel, yes it is stuck, but pops on in a second or two. I have done nothing to try and correct this. This AZ Box is one wackey receiver.
Jim,
Ok, this all makes sense to me now. The 922 decides what sat the dish is aimed at by controlling the motor and the AZBox and the Quali-TV receivers are just going along for a joy ride. But, one or the other or both are going to drop the connection with the last channel they were tuned to because the dish moved while they were aimed at the previous satellite. The dish is no longer aimed there, so they drop signal until you switch satellites and channels on those receivers to match where the dish has been relocated to.
At least it is something close to that, you might have a few personalized specifics in how you have routed your IF input cables from the LNA/LNB to the receiver, but the effect is virtually the same all around.
I can duplicate this action with my AZBox. If the actual signal from the sat is lost, it will either display a frozen "last image" of the channel it was last looking at or it may display the "no signal" message. That seems to depend upon the firmware (image version) installed.
Sometimes the channel will "pop" back in if you return the dish to the original location, sometimes it requires a nudge by channelling up or down and back.
The Quali-TV might zap right back in, almost immediately, but it is an entirely different animal than the AZBox. There is nothing wrong with the AZBox here, it is acting just as it "typically" does. I would have stated that it is acting "normally" but "normally" for an AZBox is not the same as "normally" for any other receiver. I am sure that you comprehend that statement.
Now, I cannot explain WHY it does so, but it just works that way. If I were to theorize the reason why, I would say that the AZBox scans the signal periodically. If the signal is lost, it will still scan for it, but it only repeats its scan on a much slower basis. So, every so often, it rechecks the signal. You notice the great delay in between when it doesn't regain its composure and display the original LIVE signal once again.
Try duplicating this "freeze up" and then just walk away for an hour or more or whatever it takes and come back and check it. I am curious if after a while it doesn't eventually pop back in. I never tried that, I never thought about it before because my AZBox controls the dish. It's only when I drop signal for a long time or when the LNBF gets disconnected somehow from the AZBox input IF line.
