W7ACS DSTAR Repeater up and running – thank you to ACS Tech Team

A Cold Day on the Roof

On Saturday November 4th at 0900 the ACS Tech Team assembled on Capitol Hill to install the antenna and repeater equipment to breathe life into the W7ACS DSTAR repeater which has been silent for several months.  It was previously located on top of the Seattle Municipal Tower.  It was not working well at that location and was subsequently removed and remained in storage until now.

Recently, ACS leadership appointed a new team of COMTs to lead the ACS technical planning and work projects.  The first project on the list was restarting DSTAR.  We thank Doug KD7DK for taking the lead and organizing the team to plan and carry out this work which required two visits to the Capitol Park site as well as a lot of work by the team in assembling, configuring and testing the equipment and software.

The final installation took place on Saturday November 4th, a very cold and threatening day following the first snow fall of the year.   The work required transporting all the gear and tools to the site, removing an old 22 foot UHF antenna, preparing the cabling, installing and testing the equipment.  Additionally,  some alignment work was completed to improve the connection of HamWAN with the Queen Ann site.

We want to thank those who participated in this project – the team includes:  Randy W3RWN, Casey AE7SL, Mark N7LYE, Carl N7KUW, Tom N7OEP, and HamWAN engineer Nigel N7NVH.  They donated both their time and equipment to this site installation.  We especially want to thank Doug, KD7DK for his leadership and coordination of the effort, many of the planning methods for this project will be leveraged for future work.

So give the repeater a try:  This is a DSTAR only, digital, narrow band repeater (IC-4000V + IC-RP2C + Raspberry PI Gateway) operating on 440.7625 with a +5.0MHz offset.  It is open to anyone to test out.  We would be interested in your reports of coverage.  Its operating at 25 watts with a modest gain antenna.
