Appendix 2 – Studies Required To Assess Feasibility Of Second Adjacent Channel Co-siting
1. Filtering and combining equipment
Vendors of filtering and combining equipment for AM broadcasting should be surveyed to determine whether it is technically feasible to design and build equipment to combine up to five signals 20 kHz apart in the 1600–1700 kHz band. A first approximation of cost to build and install should also be obtained.
2. Receiver testing
A sample of current receivers should be tested to determine whether the existence of multiple signals would create destructive beats across the AM band. The tests should use signal levels as high as practical to simulate conditions near the broadcasting site. DGSE's laboratory is capable of undertaking such tests.
