154.745 is not a valid frequency, neither is 155.740. 154.740 or 154.7475 are valid, as are 155.7375 and 155.745.
In any case, there aren't even any VHF high frequencies on that KEH912 license, only low band, so that's clearly incorrect.
The only active license in Ulster that matches either frequency range is WPTX795 - Kerhonkson-Accord First Aid Squad, a repeater on 154.740. I seriously doubt there are two repeaters being used in the same county just 5 kHz apart. There are no pending applications for either frequency range in Ulster either.
So if there is a simulcast on 155.745 (82.5 PL), then it's unlicensed. If either of you can figure out what the correct frequency and PL are, submit it and I'll make the correction.
