Is there a his followed by a pop or just a random pop every now and then?

If I remember those have fixed antennas on the receivers, try to have them closer to the performers and also try to get them higher up, preferably above peoples heads.

How are they connected to your mixer, XLR or 1/4 plugs into line inputs?

If using XLR connections do you have phantom power turned on to those inputs? If you are using/need phantom power and your mixer only has global phantom power as in all on or off to all channels use the 1/4 inch line inputs if your mixer has them.

What I'm getting at is that some active equipment like mic receivers don't like having their outputs hit with phantom power.

Update. The main problem was my mixer.  The right channel was going.  Add that to the mic frequencies at 537.500 and 537.900 and it was a recipe for disaster.  Spent some money today.  Hopefully no more problems.

What did you get?

That may have been a broad "shotgun" approach to the problem, but if it worked for you.

I picked up a Yamaha mg10xu mixer and 2 sets of Shure BLX288/PG58 mics , I run a small karaoke show so I didn't need a large mixer and I didn't want to go too expensive on the mics knowing drunks will be using them but at the same time wanted something fairly good
I'm planning on sending my other mixer Peavey PV10 at in to get it fixed giving mea decent backup

Those frequencies are quite close.  Often if you read the manual, you will find that they will advise you to use one or the other with frequencies this close.  Glad to hear you found a fix, whilst not what any of us want, it sounds that you have learnt a lot from the experience.
