The low band range is definitely severely reduced and sounds to me as if the standby transmitter site at the HQ off Wendover is what's in use. One can only speculate that the primary low band site is off line, and hopefully so only for the moment.
The UHF side is apparently a non-synched simulcast system, has been miserably bad for years, and sounds even worse now. Don't expect much, if any, improvement until it either becomes a single site source or simulcast transmitter synch equipment is installed.
