29. re connecting to a utility water pipe connect to it within 5 feet of where it comes in from the dirt This keeps someone else from coming in later and putting in non conductive pipe making your ground useless Sodium bentonite can be used to enhance a ground e f you are using ground radials they should be as long as your antenna is high to be effective Try to use the moistest dirt possible For example if there is an air conditioning system install a rod where the condensate drips Look to see where the rain comes off the roof to find moist areas Look for any creeks or ponds Running a long wire to a creek or pond far away may not be effective the ground system needs to be in the area of the antenna Or you can possibly install the transmitter in the area of any great natural ground Be sure all your connections are good The wire should be bright and shiny use steel wool if you need to and then tightly clamped and or soldered with torch and electrical solder and then weatherproofed with silicon Generally the deeper your rod the lower the a resistivity will be Bury any horizontal wires the more ground dirt contact the better Just an inch or two below the E a surface will do You can use a flat blade shovel s d to create a trench that the wire can be laid into This works well with lawns It is best to bury your rods entirely if possible to avoid anyone tripping over them the lawn mower hitting them ect Some will bury any m
30. rn in 30 60 days to check to see if the change has been done We have never heard of one of our transmitters being shut down because of improper installation the agent has always given the customer time to fix any issue and has allowed them to continue to operate Please be aware that even if your equipment is properly installed and passes an FCC inspection you might still be the subject of a complaint from a nearby broadcast station or member of the general public Inappropriate or frivolous complaints are filed with the FCC regularly RangeMaster may offer advice on how to install a transmitter but the customer is responsible for rule compliance The FCC is an independent governmental agency answerable only to congress we cannot guarantee and or we cannot be held responsible for what the FCC may do or decide in any particular situation The 3 meter combined length specified in Section 15 219 b refers to the length of all radiating ele ments Attaching the ground lead to an unshielded radiating object or the addition of a ground screen will cause the effective length of radiating elements to exceed 3 meters in violation of Sec tion 15 219 b 10 Converting from agile module to crystal Reverting back to the crystal First remove the AM1000F module remove the two nylon screws and gently rock the AM1000F to remove it from the socket You can leave the two nylon standoffs if you want or they can be removed from the bottom Install th

32. ty is observed and no confusion results with a station for which the FCC issues a license A typical encounter with the FCC would entail just phone call from them asking for your certifica tion number Most of the time as long as you are using a certified transmitter they won t even come by to inspect your installation You don t want to be using an uncertified transmitter especially a kit if you get a call from the FCC It is a good idea to broadcast your contact information at least hourly so that in case the FCC wants to contact you they can easily Also you can leave a package at the transmitter site where it can easily be seen containing the certification information in case the FCC should visit when no one is present When you go on the air with a part 15 do not contact the FCC to let them know of your operation they don t want you to They have no way to deal with the information They will find you if they need to We have had many contacts through the years with the FCC if you get a visit just be honest and open I have found they are easy to get along with and pleasant unless they feel that you are trying to pull some sort of trick on them Like I said before most of the time a site visit shouldn t be necessary but if it is be open and honest if there is problem honestly present your side If they want you to change something to bring you into compliance they will give you a paper describing what needs to be done and then retu
