RFI Frequency List
The RFI frequency listings, given below, result from a number of years of RFI monitoring programs, use of the ACA/ABA database, from astronomical observations reporting RFI, and from other sources, where appropriate. The information is offered, as a way of helping observers identify common RFI, and to ascertain to the nature of the RFI sources, and the RFI's location in the RF spectrum, for observational planning. Quite a number of Analogue and Digital TV Frequency listings are given below, with other listings at TV Frequency Listings
