Compare the voltage present on the LNB input connector when switching from odd to even. it should be about 18 to 20 volts for even transponders and 13-14 volts for odd ones. If it is above 15.5 volts when calling for odd transponders, the LNB will send only even transponder signals to the receiver, which means you have a bad receiver.
FWIW, half a dozen years ago, the geniuses at JVI decided that they would have their 16 port multiswitches put out nearly 16 volts on the "odds" input so that the voltage could better be sustained over long cable lengths. Unfortunately, I installed three of them in a headend where the cable length was only 30 feet, and they called for the evens instead of the odds. JVI said they were aware of the problem, and that all I needed to do was to install a couple of 200' coils of RG-6 between the multiswitch and the LNBs, and the voltage would drop down to the range for odd transponder selection.
I instead installed VBC voltage blocks and dedicated 13v/18v LNB power inserters and will never buy another JVI commercial product. End of rant. If this is not a receiver voltage problem, then it is an LNB problem. Peabobb should try moving the coax to one of the unused LNB ports as litzdog911 suggests. If it is a bad receiver, then the receiver surely should be replaced, because receivers so inexpensive that it is almost never worth the expense and inconvenience of having one repaired.
