Sync is over power and no surge on the line except for the LTM1 built in surge. Remember, I am seeing this on all 4 radios, but like josh said, .0001%, so I was really wanting to see if other see this, and those that don't, do you use shielded cable and ground the drain at the bottom and never see this? Or do you use sync over timing port and never see errors, it seems weird that already about 50% think it is an issue and 50% think that it is normal?

Is sync on the timing port or power port? If on power, do you have a Cat5 surge protector and what type? If it's a 300SS, get that out of there and put in something newer and better, or at least bypass it temporarily to see if that's causing the CRC errors. If the counters are not incrementing and it only occurs let's say when there's a nearby lightning strike, then nothing to worry about. -----Original Message----- From: Roland Houin via Af Sent: Thursday, November 20, 2014 11:37 AM To: John Seaman Subject: Re: [AFMUG] How common are crc errors on pmp100 I'd clear the counters and watch.. if the errors climb quickly, you have a problem.. it could have been a single event weeks ago that caused the problem. it would be nice if we had a mib to monitor the crc errors so we can tell when they happen. roland > This is a radio that has been up for 93 days, it is very heavy on traffic, would you say there is an issue with this radio? It is on a clean tower that only I am on. There are 4 other canopy radios on this tower receiving sync from a CTM1. All radios are just CAT5e cable non shielded, length is about 180� tops. Also there is a PTP800 with lmr 400 ran along with it, I never noticed this before, all other radios are showing about the same number of CRC errors, is this expectable?
