Where are most of the FM broadcasting tower farms in St. Louis?

105.7 has been on the master antenna at least a year, and 95.5 has been on the DeBalleviere tower that 101.1 used to run off of. Reception in St. Charles County has suffered of 95.5, but I'm pretty sure they have improved reception in the places where their target audience is. I honestly can't tell any difference between 105.7 then and now in St Charles County; I'm guessing it was likely done so they could combine operations and not have to maintain a separate site from the rest of the Emmis properties. 97.1 suffers from being on a short stick, and it also suffers because it is on the IF channel of KSLZ at 107.7 (97.1+10.6 = 107.7), which causes it a lot of interference in SoCo, and the short tower 30 miles from the city causes them multipath issues with the downtown skyscrapers.

Both the previous JeffCo stick and the new master stick for 105.7 had no trouble covering your house in St. Charles. Your place was well within the citygrade contour of the old stick. The reason for the change was likely because the JeffCo stick only covered a small part of Madison County with a citygrade signal. Edwardsville, Alton and Wood River were well outside the citygrade signal. Getting a shot at that audience was probably worth well more than keeping a huge signal that covered a large swath of rural area and mostly country music listeners.

I might be able to ease your concerns. I've been working with some engineers recently, and they claim that living by FM radio communications towers pose no risk. That being said, it is possible to have experience internal body damage if you happen to be right next to the antenna while working on the tower. Certain areas of your body do not have heat sensors, and can actually be cooked by the amount of power being radiated by the antenna if you do not power it down before climbing up on the tower.

At the same time, I have been doing some research that suggests the opposite. There are quite a few sources that suggest that people who live under radiation sites like Mount Sutro, California are at a high risk for certain types of cancer do to the radiation given off by the Sutro Tower.

Radiation from any FM or TV transmit antenna can be looked at by taking a mostly inflated balloon and squeezing it fromt he top and bottom...see the sides expand?? Now NO antenna has the radiation pattern of a ROUND balloon or similar ball...(thats call an isotropic model; does not exist in real life) however, the radiation from antenna is designed such that people living right below them or within a certain mileage are actually in a radiation NULL.....but the time you get to a spot where the RF is strong enough to really matter, people are far enough away to not be "cooked"...Especially sites like Mount Sutro...

Ranger, if you have not taken any EE courses and NOT involved with on a regular basis, then you have no right to spread any falsehoods like you did with the Mount Sutro thing..I cannot explain it totally in one posting...and wont attempt to..but being around RF for 40+ yrs I think I know a thing or two about it....problem is the NIMBY...people can "claim" anything..but that doesnt mean its true....Most of those against towers have poor information or are incorrect in their "facts"..they think a tower in their area will devalue their expensive homes...even those who built AFTER the towers were there 1st.....SMH

It appears that you didn't read my refutation after conversing with several engineers. Have you actually looked up any of the bogus stories "professionals" have posted about Mt. Sutro? There are tons of articles available over the web that claim "hidden dangers" from living too close to a major emissions site. It's enough to make someone worry (for no reason).
