Ok thanks for clarifying. Then the RR reference database is wrong because it lists Monoc Tac 1 as 502.6875. Someone should fix it.
I never said anything about Monmouth County. However if you go into the db under UNION County, you would see the frequency is incorrect. Someone must have submitted an incorrect change of frequency I am assuming. It threw me off completely. I have been very busy with work but will try to submit the correction if I get a chance.
