Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

Yeah.... There is definitely something there below the Orbital AND WW1 Carriers. It certainly could be interference (use TPT's bare LNB suggestion to take a "look" around). It looks like cross pol but it should null much, much better than that. You are losing about half of your C/N on the Orbital XD...

Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

Allen, We may have a high tech version of Segal's Law... Typically a polar dish is the easiest to reaim. Not necessary that they work very well but if the polar adjustments were setup correctly, just crank it around, optomize and your done. I have had to physically tie down a number of old polar mou...

Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

Sorry it has taken so long to get back to you. I am working on an AM ground system project that is taking all my time. What scale (db/division) are these plots? 6db/div? If so, I think that is a little too low. It isn't surprising that you didn't see much change in the AG but would have expected to ...

Re: ADJUSTING CRANK FOR SAT DISH

Lacking a direct bolt on solution, I will probably just build another couple of my all-thread concoctions. I have a confirmed frozen crank to inspect and measure Monday and will get it fabricated and moved in the next couple of weeks. Then I am off to a 3 tower AM ground system rebuild... Lots of fu...

Re: ADJUSTING CRANK FOR SAT DISH

I has been many years for me as well and it was a crank type but it came from a local TVRO dealer.

Have you talked to a specific person?
No, it has probably been a decade since I last ordered an actuator.

Dale and I must have hit send at the same time...

Back in Feb, I called Dawnco and was told that they had motorized actuators but didn't have crank types.

Have you talked to a specific person?

Re: ADJUSTING CRANK FOR SAT DISH

Actuator or Jack. If you find a manual / crank polar jack let me know where... I have been custom building jacks out of large all-thread and a few pieces of angle. A couple we just drilled holes and used jam nuts and on a couple that I knew were frozen beforehand, I carried my motor welder and welde...

Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

Hi all, Someone sent me a link to a cool online live satellite spectrum analyzer operating from various dish locations. https://satsignature.com/ I have saved plots from all of the AMC18 carrier groups as (similar to those at amc18migration.com) well as the opposite polarity of those same frequencie...

Re: RM105 Desk

It appears that TPT is correct. I was curious about the TM105 because I had never seen a SoundCraft product aimed at radio. It appears to be a sort of radio/performance hybrid console. I found a TM105 manual on line and it specifically says that the Aux output is post fader/mute. It also mentions an...

Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

There is probably your problem. You need at least a 25khz LNB for most modern receivers. I am a little surprised that all of your receivers locked. I found a 500khz at one of my clients and it worked on AMC18 but took forever for the receivers to lock with less than stellar EB's. I tested with a use...

Re: Offical AMC 8 Transition Thread (was Sat. AMC-8)

I don't recall seeing an Orbital labeled RX at any of the stations that I have reaimed so can't compare. Your AG going up to 54 but EB down that low sez that you have plenty of signal but the quality is bad. Can you peak the Premier signal to EB>15? I haven't aimed anything that wouldn't achieve >15...

Please do report back on what you find and how BW is to work with. I have a couple of clients pushing back on Nautel because BW's prices are lower.

Re: EO Pulsar 1KW problem

This was the point of my question several posts/tales earlier. A bad fuse that is melted vs. a fuse that is violently blown are 2 completely different situations. A larger fuse IS NOT the answer either. If it is a fuse holder problem, the holder will probably melt loose and cause all manner of havoc...

Re: EO Pulsar 1KW problem

One my oldest clients nursed a Raytheon RA1000 far past it's useful life. It was not unusual to get a panicked 6am call from the owner every couple of weeks telling me that one of the meters was down and he had replaced a tube but that didn't fix it and he replaced another and another and another.
