Repeater Status as of 6:30 am 9/1/16:
The 2m repeater is experiencing intermittent intermodulation problems. It causes the repeater to transmit without user input and sounds like a howling or screeching.
A number of things have been investigated and tried, and further work will be done soon.
The 70cm repeater is unaffected, and is recommended for use until the 2m problems are resolved.
NEW LOCATION - Finally!
The repeaters were moved to Fire Station 4 on August 26 Initial testing shows that the coverage area is considerably better than we had at the temporary location. A big thank you to Ray, N1IUU for patiently hosting the repeater during its exile.
New antennas were installed 8/23 on the roof of Fire Station #4, using a bucket truck and very helpful crew graciously provided by Longmont Power and Communications. Thanks to Peter Perez of Longmont OEM for arranging their assistance.
Many thanks to Doug Sharp of Triple C Communications who generously obtained the antennas and donated them to LARC without charge.
Below is a bird's eye view of the 2m and 70cm antennas, looking south. (The third antenna in the background is one of the fire station antennas).
19" rack rails were custom fit and installed in the repeater cabinet in preparation for installing the repeater equipment. (A large nest of wasps in the cabinet door delayed the process, but they were soon routed by insecticide.)
