You can switch the coaxial cables coming into your box & see if the weak signal reading follows Tuner 1 into Tuner 2. You can also try another output on your multi-switch that goes into Tuner 2. I've read about 10 point discrepancies between tuners but never this much. You aren't using SWM technology (only one coax going into your receiver) are you?

If you have a second receiver you can see what the numbers are on that receiver.

No, I have 2 cables going into the receiver. When I switched the cables the weak signal switched also. I tried changing out the BBC and could see no difference. How do I change the output on the multi-switch. And where is the multi-switch? I'm pretty much a novice with this so any help is appreciated.

Thanks

The multi switch would look something like the second picture in this link.

You can find it by following the four coaxial cables from your dish's lnb until you run into it. Sometimes it mounted right under the dish after the installer 'drip loops' the cables. If four cables are run directly into your house then it probably is in your attic.

I'm not saying that's the problem, but you have to start somewhere. My first multiswitch was installed outside & the unused ports were never capped; it started to fail & fry within a month. You mentioned you switched cables, did you also try switching the b-band converters?

If you find the switch first switch the two cables with their respective switch ports. Go look at the receivers readings & see if the problem is reversed. If they reversed, keep the good port connected & use one of the other ports. Don't forget to cap the old port with the extra plastic shield from the new port. If this turns out to be the problem, I'd say get a new switch.

If this doesn't fix your problem you could easily have something wrong with the second coaxile cabe & or connections. Make sure the cable is RG6 & is not damaged. Check the connectors at both the switch as well.

Once you exhausted all the suggestions that are laid out here such as swapping cables on the back of the receiver as well as the BBC's and finaly the switch. I would get in touch with D Customer service as this may be outside of your realm. It is more than likely a bad connector that needs ot be replaced or the cable itself. One thing to point out is did they install to an exisitng cable that was used for cable tv? If so are there any splitters in that line?

Since the op says that the dish was installed a month ago Directv should be called to fix the problem.

Good Luck

Just a quick follow up. Direct TV came out this morning to check on my low signals on tuner 1. They replaced both cables and all is fine. Signals now in the mid to upper 80's on 99c and 103c.

Thanks for the responses.
