COLORADO CONNECTION NEWS
> By: Paul Shackelford WBØQMR
> Well there was some activity last month that did not make it into the news
> letter because we had finished it before I got this info. So here is the
> account of the trip to The Colorado Springs Repeater as submitted by Jim
> Patton (NØWGQ).
> Thanks very much to all of you who helped with this project and especially
> to Jim.
> On Wednesday morning, Sept. 14, 2011, Ted N0NKG and Jim N0WGQ went
> to the site. When we arrived we confirmed the radios were indeed
> off-line. The main power switch on the bottom (VHF) power supply
> was on and the cooling fan plugged into it was functioning confirming
> the presence of main power. The main power switch was cycled with
> no discernable effect.
> There are three fuses next to this power switch. Each fuse was tested
> and the top one (10A, ceramic) was open. The other two fuses were good.
> All we could find in Ted's toolkit was an 8 amp fuse so we installed
> it and the system came alive. Several radio contacts verified proper
> operation. Because we didn't have the specified 10A fuse, we decided
> to measure the current to see if the 8A fuse would be adequate for
> extended operation. The current varied between 0.2A (idle) to about
> 1.0A (repeater active) so we decided the 8A fuse would be fine to
> leave in.
> We did our best to create an inventory of fuses in the system so a
> back-up kit could could be created. We found the following fuses:
> VHF Power Supply:
> - AC side, top fuse. labeled "10A Fast", was: AGC 10A Ceramic
> - AC side, middle fuse. labeled "8A Fast", was: AGC 8A Ceramic
> - AC side, bottom fuse. labeled "5A Fast", was: AGC 5A glass
> - DC side (back). 50A cartridge type (about 3" long x 3/4" diameter)
> Note, It appears the top fuse on the AC side supplies the input
> to the power supply. The middle fuse appears to supply
> the external AC mains outlets on the power supply.
> Did not determine what the bottom fuse is for.
> Small modular Power Supply (UHF?)
> - 30A automotive blade type, ATO size
> (the older standard full size blade type).
> RLC Controller
> - In-line holder on DC input line: 1A AGC glass
> - Fuse holder on PCB: 1/2 A, 5mm x 20mm glass
> Normal repeater operation was verified during the drive down
> and other users were heard on the system later in the day.
> MANY, MANY THANKS to Ted N0NKG for all his work!!
> FYI: CMRG has made SIGNIFICANT progress on the power distribution
> generator system for main power - a very professional job.
> The 2011 Colorado Connection's Annual
> Christmas Dinner is on the books...
> MARK YOUR CALENDARS!!
> >> Thursday night, December 8, 2011 <<
> Country Buffet
> 7475 Park Meadows Dr.
> EVERYONE IS INVITED!!!
> We hope to see many new and old faces at the Country Buffet
> near C-470 and Quebec. Take C-470 to Quebec and go South
> one traffic light to Park Meadows Dr. Pep Boys will be on
> your left. Turn left (east) on Park Meadows and turn left
> again (north) at the first driveway. The Country Buffet
> will be on your right.
> This year the dinner is on Thursday night, December 8.
> Eyeballing begins between 5:00 and 5:30 PM (or any time
> after that if you're running later).
> After dinner, we will also do our traditional gift exchange
> if you wish to participate. The exchange is more fun than
> what you get; the first person selects a gift and opens it,
> the second person can either take the first gift or get
> another gift and it goes on until all gifts are taken.
> Remember to keep the gifts UNDER $5.00 and maximum of $10.00.
> HAPPY HOLIDAYS from the Colorado Connection
> Thank you Jim
> As things are going to be much slower for the next few months, look for
> these news letters every couple of months and not monthly until next
> We will be sending out BULLETINS whenever there is new news.
