In the federal government, at least in the Forest Service and the other natural resource/land management agencies we always included the full name of the agency. When there were environmental assessments and environmental impact statements written that involved a National Forest with andramonous fish the NMFS would be referred to with four letters among those who were working on the document. If you type NMFS into a search the "NOAA Fisheries" site comes up first. If you type in NMF you don't get the National Marine Fisheries Service at all.
NMF must be an eastern thing. Easterners and Midwestern folks pronounce Nevada, Na Vaaah Da when the people from that state and those who live in the Sierra Nevada, like myself, pronounce it "Na Va Da." The eastern U.S. begins at the eastern boundary of Denver International Airport.
I think the National Marine Fisheries Service and all of NOAA (including NWS) should be moved into the Department of the Interior. The NMFS and the National Ocean Service (part of NOAA) are more environmental in nature than in commerce. Move the Forest Service in there as well. The Natural Resources Conservation Service (previously called the Soil Conservation Service) should go over to Interior. Then rename DOI "Department of Natural Resources" or "Department of Environment." Consider moving the EPA into this new department as well, instead of its present status of answering to the President and the Council on Environmental Quality. Nixon's bill establishing the EPA made the agency independent of any cabinet level secretary.
Back to the NMFS and their use of radio frequencies that can be interrupted by an IFB. Many don't know it but both the NMFS and NOAA both have law enforcement organizations. My patch collection includes uniform patches from both of them. One job that NMFS that a lot of people are attracted to is counting pounds of fish caught, by species, on ships in the Bering Sea. You have to provide your own barf bucket though.
Well, this has been an education! I'll try to find out what the Air to Air FM Tactics frequencies will be for this year. Since both air to ground and air to air frequencies, as well as tactical frequencies used by the feds don't have tones on them, they are unable to tune out the IFB's. At the power and location the nearest IFB's are to the Cleveland NF tone squelch probably wouldn't do a lot of good anyway.
