Hi
My County is in the process of narrowbanding. As a temporary measure during the switch, we were planning on programming mobiles and portables in advance of our programming the repeaters etc and for a while going narrowband into wideband receivers. We don't have a lot of conventional radio channels. We are mostly Motorola digital, trunked, simulcast. We have a handful of conventional TAC channels and all the city PD's are conventional. Other than the volume issue, our initial testing using city repeaters and simplex showed good results and minimal problems. Then we did some testing on our TAC channels which have voted receivers and comparators. With some models of radios ( specifically Motorola XTS3000 portables and Astro Specta mobiles) we are having trouble opening and voting receivers. We do not have this problem with XTS5000's, XTL series mobiles or the new APX radios. Turns out that in narrowband, the XTS3000 puts out about 350 Hz of PL while the other radios are closer to 450 Hz PL when in narrowband. Motorola says there is no way to up the PL in XTS3000's. Is there something we can dovia CPS to the mobile/ portables that Motorola has not told us about? Or, have you heard of anyone solving this problem coming from the receiver / comparator end?
