SARS System Status

4 July 2018

There is an on-going, system-wide project to clean up the movement of CTCSS tones back and forth across the system. Until this project is complete, you may notice that the links appear to be working intermittently, or not at all. Casual observation will show that the audio is having trouble moving from one site to another, the RF systems are fully operational (assuming they haven't been subbed off). We will be working through the summer to correct this situation.

All three SARS UHF repeaters are now both decoding and encoding CTCSS. We encourage users to run tone squelch in their UHF radios, and to report any problems or issues they might perceive to Rod WB6ORK, Chuck WD6AML, or Paul KB6MIP. The VHF low band repeater at Sierra Peak does not encode CTCSS at this time, please do not use tone squelch on low band.

Rod WB6ORK has been spending a lot of his free time at the Potosi site (near Las Vegas, Nevada). There is no anticipated start-up date, but progress is being made on not only RF systems but also facility maintenance and improvement. More information will be forthcoming.

As we schedule more site work, I'll try and keep everyone advised of the dates for the work. Keep an eye to the FaceBook page, drop by here for updates, or catch one of us on the air.

 


 

Sierra Peak

Both repeaters at Sierra Peak (UHF and low band) are in service and linked to Oat Mountain.

The N6FFI repeater (52.800 MHz, -500 kHz offset, CTCSS 82.5 Hz) is operational, but is showing its age. The output power of the MICOR uni-chassis base station is a modest 58 watts from the PA, 27W going up the feedline. The antenna shows a return loss of 12.61dB (1:1.61 VSWR). The receiver sensitivity is within spec.

The WB6ORK repeater (447.100 MHz) is operational and within specs. The repeater encodes and decodes CTCSS. The QUANTAR repeater continues to serve us well, although it will need some preventative maintenance in the form of dust removal and filter cleaning soon.

The link to Oat Mountain is fully operational.


 

Oat Mountain

The WD6AML repeater (447.900 MHz) is operational and within specs. The repeater encodes and decodes CTCSS. The Daniels MT-3 system has been adjusted for 20 watts going up the feedline. The multi-bay dipole tends to favor the area west of the repeater.

The links to Sierra Peak and Frazier Mountain are fully operational.


 

Frazier Mountain

The WB6ORK repeater (447.100 MHz) is operational and within specs. The repeater encodes and decodes CTCSS. The Daniels MT-3 system has been adjusted for 35 watts going up the feedline. The antenna pattern favors the Central Valley.

The link to Oat Mountain is fully operational.
