the coordinate towers are kindof an outlier in how aweful they are, and i had the same experience. what i did was just do all the other busywork like fussing with cleaning and doing hashes instead of bothering with signals untill day 8 when i could turn their degredation off. they never got better, i had one break down, then break again once i got a single signal, then break again in the time it took me to drive back from fixing it. they will kill your experience
