Hearing the blippy sqeeking stuff from units in the field only on the south cell. Seem to hear it most on Chula Vista PD, La Mesa PD, and Lemon grove SO, at least those are the talkgroups I see when i look at the display. It catches my attention because when the units get this problem, it sounds (on a Motorola) EXACTLY like when I am out of range of a cell, say trying to listen to the south cell at I-15 and Poway Road. That causes my to check to see if my radio has roamed to the wrong site, then the dispatchers transmit and sounds fine. The transmitting units as far as I can remember were not in adverse areas or inside buildings, just normal transmissions in common areas. Noticed the last week or so, and the dispatchers do ask for a 10-9 on these.
