We have a very nice Shure UT4A wireless diversity receiver (UHF, 615.9 Mhz) that we use with a UT1 body-pack transmitter. Unfortunately, the transmitter seems to be failing as it has been increasingly losing connection to the receiver (both sides!) during live use, causing very bad "pops" as it loses, then regains connection.
Now obviously, I am hoping that the problem is the UT1 transmitter ($200) rather than the UT4A receiver ($400), but I am not sure how to check.
Worse, the UT1 appears to be obsolete, but I do not know what replacements for it I could buy that will work with the UT4A diversity receiver.
Any help would be much appreciated!
