There's a few I can mention.

WLUM. K-LOVE didn't do any improvements on the signal. The previous owner did, last summer after years of a degraded signal. The signal is going downhill again. The transmitter occasionally randomly drops carrier. I figure they will fix it eventually, probably will involve replacing the transmitter.

Across the river, 97.3 WRNW's signal has gone downhill. Used to be able to get a strong signal from it here. It's more complicated now. Their analog RDS is also down. Been down for months. People advertise on the RDS, they might be annoyed but for iHeart, oh well it's just the stream. iHeart in Milwaukee as far as I can tell has not had a full time engineer in over 10 years. Last time they had one who really cared about the facilities there was Scott Tyler (Former afternoons on 103.5) He really had that cluster sounding good. He quit and went to Florida. Felt he was being taken advantage of. That was in 2014. I believe he eventually ended up back at iHeart in Florida and wound up being in that massive iHeart engineering layoff a few years ago. No idea what he does now.
