Northern Utah WebSDR
Salt Lake area 2 Meter and 70 cm receivers
This system - which is part of the Northern Utah WebSDR - system allows user monitoring of the two meter band and the top 4 MHz (repeater outputs) of the 70 centimeter amateur radio band from a location in East Mill Creek, Utah along the east benches of the Salt Lake valley at an elevation of 4800 Ft ASL (1460 M), approximately 600 Ft (180 M)) above the valley floor.
This receive system covers Salt Lake City and surrounding communities in the Salt Lake valley. It has limited visibility into Davis and Weber counties to the north, Tooele county to the west, and only marginal coverage into the western portions of Utah County to the south.
The "SLC ATC" receiver has been configured to receive a 2 MHz swath centered at 122.1 MHz to permit reception of some of the local air traffic control frequencies. No additional frequencies are possible at this time owing to the fixed frequency nature of the receiver, the 2 MHz maximum bandwidth and the lack of available hardware.
The 2 meter "Space-to-Earth" receiver is experimental. Testing indicates that it could be significantly improved with a dedicated antenna and improved filtering/amplification: Work is underway to do this - hopefully before the beginning of Winter, 2023.

Note about reception of transmissions with subaudible tones
A number of the repeaters that may be received by this system transmit a subaudible ("PL", "CTCSS") tone. If you find this tone to be objectionable, check the NOTCH 2 box just below the volume control to remove it. If you know the frequency of the tone, you may selectively remove it using the "Vari-Notch, using the slider.
To invoke this page with a preset frequency and mode, append "/?tune=(freq
kHz)(mode)" to the URL and save it as a bookmark,
Where "n" is the S-meter reading - which is ALWAYS negative - above which the S-meter reading causes the squelch to open. This value should be 3-6 dB above the no-signal S-meter reading for that particular band/receiver combination.
If you find that CatSync does not work with this WebSDR, add "?10hz" to the URL.
Additional URL parameters are described on the "FAQ" page here.
