The licenses and applications tell the tale:
Flower City HAD the 464.4500 under license WNSH508. That expired 5/21/2005.
Finger Lakes licensed the UNUSED frequency of 464.4500 officially 7/30/2010 on WQJM208 after going thru the coordination and Canadian concurrence. (Makes sense since it had been available for 5 years.)
Flower City seemed to have re-licensed 464.4500 on KFK341 officially on 6/24/2013 after coordination, but interestingly, the COSER never went to Canada for concurrence, nor did they get a letter of concurrence from the adjacent user (Finger Lakes). (Reference the application 0005576516:
ULS Application - Industrial/Business Pool, Conventional - 0005576516 - FLOWER CITY COMMUNICATIONS - History
What this tells me:
It looks like Flower City realized they lost 464.4500 and tried getting it back, but now they are sharing it with another user VERY close. It's going to be tough to win the argument since Finger Lakes went through the process correctly, BEFORE they did. (3 years.) Finger Lakes has a VERY good argument for interference.
Lesson learned.... renew your licenses before they expire. Whoopsie... Flower City messed up on this one... now all the buses will have to get reprogrammed, or change channels in the radio to be assigned to the normal trunk.
