Latest update 2-2-2017

So as some have probably heard I was able to make a trip up the hill Wednesday to install our backup repeater.  It has already help guide us in the correct direction in figuring out the receiver problem on the main repeater.  It seems that the duplexer filter system is not doing its job to its full potential.  this is probably because of the cabinet move and not being tested or adjusted for 20+ years.  We figured this out because the back up system is on its own duplexer and antenna system, we are able to change to the backup system when the problem is there.  We did that last night and the noise disappeared instantly when switched to the backup.
The plan of action is to retune the filters and see how far out of adjustment they really are.  If that doesn’t improve the problem we will borrow a different kind of duplexer and install it to see what the result is.  Finding this issue does not rule out that there is possibly a “rouge” station on the hill producing the interference and that no matter how good of filter system we have it will filter the interference out completely.  We are hoping to fix our issue and find the interference at the same time with out having to purchase a new filter system (very expensive).

Make sure you reserve the date!



Saturday 9/24 Hill trip

Well yesterday’s trip was kinda a bust.  Went up the hill with the intention of installing the cabinet fans but changed that to finishing the control receiver installation.  Ed made the trip up also and helped make the power cable for the receiver.  So after getting it all hooked up and the old one removed from its temporary spot we powered the new one up.  It immediately started flashing a “alarm” light that something was wrong with the receiver.  Noticed the COR light on the controller was on so figured the was configured incorrectly.  Grabbed the laptop and started looking for the Motorola programming cable but couldn’t find it, left it out of the laptop bag when I got a new one that holds both laptops a while ago. So I ended up reconnecting the temporary control receiver and calling it a day.  Chalk it up to a educational trip, can’t win them all.

We did make some new friends while we were up there though.  A gentleman came in the building while we were working and asked if we had some spare hardline jumpers.  Ironically David had donated two large storage totes of hardline jumpers.  Turns out he was with the 440 dmr repeater that is in the building next door in the same cabinet as Brett and Brian’s 440 repeater and hamwan.  So got to see how there system works and they really encouraged me to get a dmr radio and try it out.  They also complimented us on our repeater and its coverage sense they lived up by Seattle and have no problem getting into the repeater.

Looking to try and go up the hill next Saturday if things go good this week getting prepared for the new job.

More work to the repeater

We got the ground buss mounted on the cable track, Polyphasers mounted to that, only 2 feed lines have been hooked up to the set up so far as we ran out of time.  It is to a point that there is a list of things I can button up on my own without David’s assistance so I’ll be making trips up in the coming weeks.  David brought one of his fancy antenna feedline analyzers so we checked the north and south antennas.  North is perfect with a 1.2 swr through the amateur band.  The south has issues and will not be used until we find the problem, thinking it has water in a connection or something but will take tower work to trouble shoot.  We are planning on doing that in September so weather conditions are more favorable.  David’s test equipment took screen shots of the two results so when David can get them on a computer and email them to me I’ll share them with everyone. Two pictures have been added to the 2016 upgrade page.

August 5 trip

Made a short trip up the hill.  Installed temporarily the old control receiver. Every thing seams to work on it so we now have more control if needed. See picture upgrades for current pictures.

July 16, 2016 work


From Jeremy KC7VCG:
I went up the hill again today. Got the autopatch moved and working, terminal strips mounted, temp sensors hooked up, and the weather radio temporarily hooked up. The weather radio is temporarily hooked up until David and I both get back up the hill to mount and wire the control receiver. I thought it was important to have the weather radio working for weather alerts and amber alerts. Haven’t started labeling everything yet, figured I’ll wait till everything is installed sense things might get changed as we go. All in all I think it was a successful day on the hill.

Saturday’s progress


Here’s Saturday’s progress.  Got the intertie controller, link radios, there filter systems, power to them, and feed lines connected.  All seems to work but not passing dtmf tones to tiger mt. or Portland.  Pretty sure that it’s a audio level adjustment that’s needed but at least the north-south trunk is back operational.  Still need to hook the control receiver, aprs digipeater, temp sensors, etc up.  The main repeater is fully operational again so if you experience problems please let me know so I can troubleshoot it.  We still have a lot of odds and ends and also going to test-tune all filter systems to finish in the coming weeks.
