I just heard the lone Grey Forest officer (9410) go off watch for the night and confirmed some things.
Between tonight and one time last week, I've heard the Grey Forest officer on 154.085 (car only), while at the same time heard the car and an unk base on both sides of 156.150 (very weak at my location in NW SA -- stock antenna).
Tonight, I finally heard Grey Forest, on both sides, on 155.910 (Balcones Heights PD). Also tonight, noticed that 156.150 and 155.910 are simulcast. All the while, no Grey Forest traffic heard on 154.725 (Leon Valley PD).
I've previously heard Helotes FD use 154.085, as a response channel, and possibly PD too (?). I suspect this may be a Grey Forest PD / Helotes PD common channel (car-to-car) since they no longer benefit from the same dispatch center (Helotes is still heard daily, dispatched by Leon Valley 154.725).
I recall earlier this year hearing that Leon Valley was going to increase the annual fee for police dispatch services to Grey Forest...something about a new method of calculating the billing (using utility hook-ups vice number of calls per service? -- something like that). I guess Grey Forest found a better deal in Balcones Heights.
All these small departments...but what else can you listen to around here?
