I plan to run over tonight and put a drop light in the rack with a 100 or 150 watt light bulb to put off some heat. I might also tighten up the squelch a frog hair. The repeater is a RANGER unit with a Neutec transceiver on 220. The duplexer is 4 Telwave cans. - Mike

Some repeaters have better low-temperature performance than others, especially when fully-compensated channel elements are used. Perhaps the duplexer is affected by the temperature, although 45 degrees is hardly an extreme. It may be worthwhile to install a simple thermostat-controlled resistive heater inside the cabinet. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> [mailto:Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> ] On Behalf Of Michael Ryan Sent: Sunday, January 03, 2010 12:45 PM To: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> Subject: [Repeater-Builder] Cold temps and repeaters Down here in Florida this week we are ENJOYING somewhat of a cold wave. Today's high around Tampa about 45 degrees. A bit unusual. My repeater on 224 MHz is having a fit today. Sounds like some kind of a mix getting in, sometimes not strong enough to open the squelch, sometimes it will creep in after the repeater is keyed either by the id'er or someone keying the machine and tripping the cor. My machine is not out in the elements but is also not in a particularly climate controlled location, inside a warehouse. Can the below nom temps be creating some issues with the nearby environment and some equipment elsewhere or is it more likely that something is 'chilly' in my own rack? - Mike __________ Information from ESET NOD32 Antivirus, version of virus signature database 4740 (20100103) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com
