b-band converters are not connected when I had the swm attached. voltage I checked and was ok. the seller I purchased it from is fed-exing a new lnb to me. should get it tomorrow but it might be raining here if not I will try it and let you know what happens. has to be the lnb? unless some strange that this brand lnb is not compatible with the h24/700. these are made in china so maybe I got a bad one.
