This is conjecture, but I think it is correct.fo71 said:Hi... I looked at other threads and although they do mention SWM signal strentgh, they don´t mention what exactly what those numbers mean, so...
My question is, after installing an 8 channel SWM switch, my receivers now show "SWM" along with 101, 103's, 99's, 110 and 119 as if it was a sith satellite. It show signal strentgh transponders 1 thru 9. Does someone know what do this reading mean? What is being tested? Perhaps the communication between the receiver and the switch?
The signals in those pages represent signal loss between the SWM and the receiver. A 100 means (essentially) no loss. The reason this is measured separately is because when you tune a channel, it can be sent from the SWM to the receiver over one of 8 different frequency bands. If a frequency band doesn't work well, then you might tune a channel one time and get it in just fine and then tune it another time and not have it work because it's on a bad frequency band. It's essential all the bands work well.
So, if you look at the numbers, you'll see the signal loss goes up as the band number goes up. This indicates the bands are numbered in order of increasing frequency, and signal loss increases as frequency goes up. If you have long cable runs, the higher numbers could have significantly more signal loss, while the lower ones will be less affected. I think my lowest figure is 96 on this page. I do not know what the lowest acceptable number is.
