    I had a question that I've been wondering about.

    In the Signal setting screen , what is the SWM signal?
    Is there only supposted to be nine?

    Is it something from the satellites too?

    The SWM signals screen is (was) useless. the 9th channel is the communications channel which is visible to all receivers in the network

    I read somewhere that it has to do with the communication between the SWM mechanism.
    It is not really a Satellite Signal Strength reading.
    I never check it.

    Just wondering. Because its changes from time to time in strength and Wasn't sure since I have a swim 16 if it was supposed to have 16 spots and not 9.

    Only reason I brought it up is I just moved my Dish to a Pole mount and wasn't sure if something might have happened.
    Everything seems good though.

    The SWM16 has two "sides" and your SWM screen will only show the signals from one side, the one the receiver is attached to.

    OK that's good to know.

    Actually the communication channel [the 2.3 MHz FSK] isn't shown.
    #1 is the guide channel, with 2-9 being those used for tuners.

    Why is there only nine if I have 10 tuners?

    9 channels on each side of the SWM16

    Just the design choice DIRECTV made I suppose;

    They didn't see it as necessary to include a signal strength scale for the SWiM's bi-directional control channel.

    ALL SWiM units [to date] are based off of supporting eight tuners on one coax.
    #1 channel is shared to supply the guide data, but the other 8 channels are for individual tuners.
    If you really have 10 tuners, you need a SWiM-16 [with two coax outputs] for all to work.

    He does not have 10 tuners. He's saying that he's seeing 9 tuners on the SWM signal screen when supposedly the SWM network has 10 tuners. 1 to provide guide data, one to provide communications (FSK) and 8 for programing

    That's what I grasped from his question as well. He wants to know why no signal level scale on the SWiM S.S. screen for the 2.3 MHz control channel's tuner.

    The FSK is not really a tuner. There's not much point in measuring the signal level of a control signal from the SWM16 to the receiver. Actually there's not much point in measuring the signal levels of the SWM tuner channels either, but I guess they were quite useful when the SWM system was first installed, for diagnosis purposes.

    The SWM signal strength screen is being removed? That doesn't make sense. It isn't as useful as the signal strength to the satellites, but isn't completely useless either. Presumably it would help identify problems with cabling in some cases.

    How?

    Only way is with a meter that can read the FSK

    Perhaps the coax "metrix" found under the hidden menus.

    If there is a problem with the FSK signal, you can't "talk to" the SWiM anyway.
    Also being that it's 2.3 MHz, the loss is so much less than the SWiM channels as to be pointless to measure.

    It seems the SWiM screen caused more questions to the average customer than it was helpful.
    It was good to get an idea of the [excessive] loss from the SWiM to receiver leg, but if the installation was done correctly, there was little use.
