The RF Specialties Group checked into both products for a number of stations wanting to get audio from one place to another without the hassles of phone lines or frequency licensing.
We were told that both the Moseley Starlink 9001SS and the QEI Quick-Link II operate in the 2.4 GHz frequency range under part 15 of the FCC rules, and therefor require no licensing whatsoever. Based on this military method of either frequency hopping or sequence coding, known as spread spectrum, both units carry two channels of 15kHz, 16-bit digitized audio. With the appropriate high-gain antenna, each will cover a range of around 30 miles line-of-sight. For lengthier paths, we were told that repeaters are available, as are T1, fiber optic, and hardwire hook-ups for other path types.
This wireless technology appears to be an ideal solution for LMA programming links between two stations, as it can transport audio uncompressed over a relatively uncongested frequency path. The units take ISO/MPEG or apt-X plug-in source coders for compressed audio transmission.
The final RF Specialties analysis on these new spread spectrum devices: definitely worth the wait. Both Moseley and QEI will have receiver/transmitter systems available late summer for less than $10,000. Access http://www.rfspec.com or call us direct for periodic updates on delivery schedules.
