The ECEN simulcast is a five site simulcast cell. Most scanners, with the exception of the new SDS series, seem to have a lot of trouble with simulcast P25 trunked transmissions. My BCD436 does pretty well on the state system when scanning the stand alone Astro site repeaters. However, once you get into the simulcast cells like ECEN, Warren Co, and the Allegheny Region, that model scanner will not do well. It might not help very much, but the ECEN talkgroups can also appear on the North Mtn site in Sullivan and the Millville site in northern Columbia Co, as well as some other nearby sites. But, they'll only appear on those sites if a radio using one of the ECEN talkgroups is affiliated with the site which may be hit or miss since most ECEN radios will likely be grabbing for the simulcast cell when affiliating.
It is a pain, for sure. But, if you really want to listen reliably to the simulcast, you would need an SDS series scanner from Uniden or a Unication pager. Both are pricy. The only "cheap" option involves some familiarity with various pieces of computer software and using a USB SDR radio dongle to listen via a program on your computer. In theory, this is cheap because the dongles can be had to under $100 (but then you need a computer that can handle the software). You can learn more about SDR in other areas of these forums.
