This is a TEST WebSDR of the Northern Utah WebSDR system.
This server is testing the use of a single RX-888 (Mk2) SDR radio as the single source for all bands. This server is experimental, subject to going offline and being reconfigured at will.
Although the RX-888 with ka9q-radio can be used to produce I/Q streams for all HF band simultaneously, only eight of them are represented here due to the 8 band limitation of the PA3FWM software.
Data from these other bands may be propagated via the LAN, or even used on a separate virtual machine running on the same hardware to feed other WebSDR instances, for WSPR decoding (as is being done on this very server) or other things like CW/FT8/FT4/RTTY skimmers, etc. This server will be used as a platform to further test such configurations.
This receiver is GPS-referenced, so the tuned frequencies should be accurate to better than 1 Hz.
This server is connected to the TCI-530 Omnidirectional antenna - the same as is used for Northern Utah WebSDR servers #1 (Yellow) and #2 (Green). Links to these and other servers are found in the control menu below.
