Hello all, Big M just installed a P25 800 trunking system here that is a 5 site simulcast system. The M radios (xts2500 & xtl5000) seem to work fairly well most of the time but there have been some totaly garbled too. Trying to listen on a scanner is another story, as is more garbled and sounds like Donald Duck talking if it picks up at all. The delay in audio from the vocoders between radios through the system is terrible . This delay causes problems if you have units in close proximity to each other where the other radios can be heard. I have heard that this delay really fouls things up when you have units on a scene like a wreck or fire where there is "outside speakers" being used......sounds like "Reverb on steriods" (if anybody remembers what reverb is). Most fire depts do switch to an analog direct channel for "on scene" comms because of this. Mike

Hello Group, As P25 is being rolled out worldwide, I have been hearing many stories regarding P25 shortcomings...Such as Vocoder problems in high noise situations, "Jitter" and "Multipath" issues from users that have converted from their legacy Analog systems, etc . The repeater issues (If any) are especially interesting for me, and would be very interested in hearing feedback from my colleagues from around the globe. Best regards to all Gareth Bennett
