Amateur frequencies may be used by guardsmen who are licensed hams, but only when not on duty. Obviously you need a radio receiver capable of receiving these frequencies, such as the AOR 8200 or the Icom IC-R20. But lately, I have been talking with other HAMS WAY far away in other States hundreds of miles away. If you are concerned about others overhearing your transmissions, use the lowest power necessary to achieve comms and dont discuss sensitive stuff ( we have xxx trucks of food, ammo, supplies, etc coming at 3:00 today). If youre of a more technical/engineering mindset, you shouldnt have any problem figuring any of this out. Ive been in the ham hobby since the 1970s. The arrangement requires certain telephone circuits (private wire or direct line to Toll Board) between the Air Defense Control Centers (A.D.C.C.) Part-CAO. This is just the kind of information the public NEEDS for when Hillary Clinton uses her Illuminati powers granted to her by the Reptilians to control Bigfoot when he comes to tAK HouR GUNzs?!!! CONELRAD had a simple system for alerting the public and other "downstream" stations, consisting of a sequence of shutting the station off for five seconds, returning to the air for five seconds, again shutting down for five seconds, returning to the air again (for 5 seconds), and then transmitting a 1kHz tone for 15 seconds. A repeater with 203.5 Hz was a Temp / Tactical Repeater, Refresh this page from the latest database entry, Return to DB page: Civil Air Patrol The BaoFeng HAM devices are inexpensive yet quite powerful. . Just my 2 cents. Show Repeater Inputs. This circular also describes and updates civil air traffic control frequencies in the VHF (118.000 to 136.975 MHz) band. Volume I That is CW Morse code commo. Menu. Some bands work better in the daytime, others better at night. Ive heard of a few occasions, and experienced one where I communicated to the other end of the state of Florida on 2 meter simplex with about 10 watts with a hurricane offshore. Vince R67 Portable and Aero Repeater Analog, Ch. Down the corner and around the block isnt going to work in a SHTF scenario. It is authorized 40 channels between 26.965 MHz and 27.405 MHz.

Effectively, this is s CB that uses a different type of modulation, or mode that has the equivalent power out of a 12 watt radio. A better option for many would be something like Midlands Dual Band Amateur Two-Way Radio. I highly recommend that you get your family a CB radio and a disaster communications plan set into place so that you can still communicate without your phones or internet post-disaster. The combination of a base station radio with a good antenna that talks to hand helds, can increase the range out to 5 to 10 miles, Any estimation of possible range of radio combination depend greatly upon the height of the antenna, and the surrounding terrain than can block signals. This message was sent by accident instead of the usual weekly EAN test. Additionally, these HTs cover a multitude of frequencies. civil Engineering Code Books cOLLECTION. I think one of the longest communications ever made on 2 meters occurred between the mainland and Hawaii sometime back (dont remember the year) under similar circumstances. The ultra-high frequency (UHF) radio infrastructure (225 MHz - 400 MHz) is used by most air navigation service providers (ANSPs) as a fundamental alternative to ensure ATC communications with non-8.33 kHz equipped State aircraft operating GAT/IFR and, in some cases to support OAT flights. One is whether its night or day. During periods of RACES activation, certified unpaid personnel are called upon to perform many tasks for the government agencies they serve. In the past, high frequency bands were typically used for domestic voice communications. Not a wire head unskilled w/comms. A great way to learn how to talk on the radio is with Squawk VFR. The Civil Air Patrol, part of the U.S.A.F., is assigned 26.620 MHz, although now the CAP uses VHF frequencies more often. All three of Green Bay, Wisconsin's television stations (WFRV-TV, WLUK-TV, and WBAY-TV), as well as Green Bay radio stations WBAY and WJPG (and other Upper Michigan radio stations) were immediately taken off line as preparations were made for high priority stations to begin broadcasting on the two authorized CONELRAD AM frequencies (which in that area would force WOMT, a station in nearby Manitowoc at 1240 AM, off the air). The new civil signals are phasing in incrementally as the Air Force launches new GPS satellites to replace older ones.
