| July 28, 2011 - Making the final connections to the remote receive site in Taylors Falls, MN is Greg N9CHA. This receive site allows hams to easily get their 2 meter FM signal up out of the St. Croix Valley and into the N9XH repeater. |
|
| July 28, 2011 - Attaching the ground wire is Bill K9WEN. The antennas are attached to polyphasers to reduce the risk of a lightening strike. While the antennas are not the highest object in the area, it's always a good idea to provide additional safety. |
|
| July 28, 2011 - The receive site electronics utilize two Motorola CM200 mobile radios, a back-up battery, temperature controlled fan, and a programmable PIC controller for transmitter identification. |

November 2, 2009 - The DB-224, 4-pole dipole, collinear antenna installation was completed by Len N9QIP and his assistant Jason. The fiberglass radome Sheriff antenna was removed. A Hustler G6-270 dual-band antenna was also installed on one of the side-arm mounts. Remaining at the top of the tower are two side-arm brackets with cellular antennas attached.

| Video - 1996 Repeater Antenna Installation |
|
The video was taken in May of 1996 by Chuck WD9GWG. It is 7.5 minutes long. You will need a high-speed internet connection as well as Adobe Flash Player 8 to view. It depicts the men involved with installing the tower sections to the penthouse of the Government Center. The repeater at the time was a Hamtronics mounted in a 19" rack cabinet. While some of the crew were installing the tower section, others were fishing coax through the building. An additional antenna was installed on a section of mast also mounted to the penthouse. It was used for emergency communications from an EOC point within the building.
In 2008 the repeater was moved to its current site. (The club no longer uses the Hamtronics unit, it was replaced by a Motorola 1225 and eventually by a Motorola MSR-2000) The tower and antenna are currently being utilized for APRS operation. |
