Do you have tools to measure the battery voltage? I’d suggest make sure you have brand new far from expiration date batteries. The voltage should be at 9.2 – 9.4V. What is the voltage after an hour, or at the time of interference. Although I don’t believe battery may cause the problem, I’d still rule it out first. Try different batteries. If the voltage drops down to 8.5V or so within an hour, than you may have short circuit problem in your transmitter.

From personal experience – I had similar problem with Lectrosonics 195. During routine daily stand-up shoot in approximately the same area of the city I was getting hits/bursts in my audio (at approximately same time, thatoccurredto me later). I sent it for check-and-repair twice, but the trouble persisted. It was total mystery to me until I played the audio to my friend and engineer. He happened to be very talented, smart guy with the knowledge of surroundings, and suggested that the interference resulted from the daily microwave feed done by one of the businesses across the street at around the same time we were shooting our stand-ups. So I guess that’s what it was. We tried to avoid that same time slot, and it worked! Go figure.
