We have an MTR2000 VHF repeater deployed here in Michigan, and have been quite happy with now, for more than 3 years. This winter has been particulalry brutal, and the temperatures have taken many excursions to significantly below 0 degrees F, for many days in a row. Adding to this issue, the building housing our system has lost many equipment cabinets and running systems. It is actually colder in the building than outside.
During the past few weeks, especially when the temperature has plummeted, the repeater has developed an issue. The symptoms appear that the receiver is off frequency, that is everyone's audio through the receiver is slightly distorted. Using the RSS software and a service monitor, the receiver appears to be on frequency. There are no other indications of anything amisss, yet a restart of the MTR2000 clears up the problem. Have any of you encountered a similar issue? Thanks; Jim WB8AZP
