  1. There have been many questions as to when the Alanspark repeater will be going on-line. While a specific date has not been set, some really good progress is being made and I think we can have the repeater up and running by this Fall. I’ll try and get a few pictures on the site, people seem to enjoy seeing them.
    The repeater location is known and final details of the site, antenna and equipment location are being worked.
    The repeater hardware itself is on the bench here at the QTH, tuned up, and working. The crystal pair came in about a week ago and I’m in the process of “aging them in” and making small adjustments so our frequency pair is dead-nuts-on. Duplexer “Can’s” are tuned up, what can I say.. DB4062’s are really awesome!!

  2. Saturday August 10th looks like the date we have set for installation of the Alanspark repeater. This will also be an opportunity to get the radio you received as part of the MERN training reprogrammed. Several of us will be on hand to do the programming starting at 9AM. There will be a short 30min “Get to know your Alanspark Repeater” show-n-tell 10-10:30AM, then were getting to work. This is an excellent opportunity to see the actual repeater hardware, see some of some of the more out of the ordinary test equipment in use like my IFR-1500, and ask all those questions I know you have been wanting to know.
    It is my understanding that radio re-programmed will continue while the repeater installation crew is at work.

    If you are interested in being part of the repeater work crew, please coordinate with Joe Callahan. Shall we say space is limited…

  3. Many thanks to all who participated today. We were able to get many radios re-programmed and the repeater hardware installed.

  4. Beginning in 2014 the Allenspark MERN Repeater experienced frequent lapses in functionality and limited ability to re-transmit weaker signals. Through observation and with the technical assistance of KI0HG, many efforts were made to identify the source of the problem with this repeater. It was determined in early 2016 that the rig was being desensitized by strong interfering signals emanating from a nearby local source. Because of spotty connectivity under the best of circumstances, a new location was evaluated at Allenspark Fire Station Number Five, which was signal-tested and found to be an excellent choice for relocation. In August 2016, with the approval of BCARES, the Allenspark Repeater was relocated to its new home near the intersection of Bunce School Road and CO 7. Much thanks go to Ueli Hauser (KB9TTI) Bob McDonald (KD0SCC) Steve Coles (KD0RFT), Bill Ellis (KD0RFR) and the Allenspark Fire Protection District. The relocated repeater works flawlessly now and has inspired the fire district to co-locate a repeater for its own public service channels, eliminating many emergency service dead spots. Thanks to all!
