What happened to channels cbs 3-1-2-3-4 & wptz 5-1-2 & cw 31-1

Hi and good day, I contacted WPTZ 5 ON Wednesday morning and received a reply one hour later. I was told " Montreal is well outside of the expected range of signal reach for this temporary transmitter. This transmitter is similar to our original one and is operating at full power, but we are at a different height and location than our original, which affects signal reach.
We do intend on installing a new transmitter on our original tower, restoring signal reach back to where it was, but we cannot do that until conditions on Mount Mansfield are conducive to that type of work, most likely spring/early summer."
So it will the 4 CBS channels, 33, 57. Today 44 Fox working well and occasionally ABC 22 channels.
