- 18. Cross Band Repeat – Repeater (3) Receive the repeater back through your cross-band system. The downside of this method is that until the repeater's carrier drops, your cross-band unit will continue to transmit, which does not allow you to transmit.

- In a fast moving situation with poor simplex coverage and no repeater, it can be helpful to place a mobile station on a hilltop or office building where they can communicate with, and relay for, any station in the net. A mobile relay station can also allow communications to follow a moving event, such a wildfire or flash flood. That station becomes, in effect, a "human repeater". Although an expedient "work-around", this is a slow and cumbersome process that can reduce net efficiency by more than half. A modern aid to this kind of operation is the "simplex repeater". This device automatically records a transmission, and immediately re-transmits it on the same frequency. Remember that FCC rules do not allow unattended operation of simplex repeaters, and that you must manually identify it
- Even when vehicles are not included, internal combustion engines are still the number one cause of carbon monoxide poisoning in the United States. Propane powered engines produce as much or more CO as gasoline or diesel engines.
- Tents should be rated for high winds, and should be designed to be waterproof in heavy weather. Most inexpensive family camping tents will not survive difficult conditions. Dome tents will shed wind well, but look for published "wind survival" ratings since not all dome designs are equal. Your tent should have a full-coverage rain fly rather than a single waterproof fabric. The tent's bottom should be waterproof, extending up the sidewalls at least six inches in a "bath-tub" design, but bring an extra sheet of plastic to line the inside just in case. (Placing a plastic ground cloth under a tent will allow rain to quickly run under and through a leaky tent floor.) Bring extra nylon cord and long ground stakes to help secure the tent in windy conditions. If you are not an experienced foul weather camper, consider consulting a reputable local outfitter or camping club for advice on selecting and using a tent.
- The symptoms of snow blindness are a sensation of grit in the eyes, pain in and over the eyes that increases with eyeball movement, red and teary eyes, and a headache that intensifies with continued exposure to light. Prolonged exposure to these rays can result in permanent eye damage. To treat snow blindness, bandage your eyes until the symptoms disappear
- In one case, the judge ruled that by modifying his radio in advance, the Amateur had committed "pre-meditated" interference, a serious charge. If you are in a position to save someone's life or property, be sure you are ready to defend your actions -- and possibly lose -- before pressing the mic button.
- If you plan to use other radio frequencies discussed in this unit, it is better to purchase the proper radio. However, if the need arises and your ham radio is all you have, the FCC will probably not prosecute you for using it - if the use falls within their strict rules for emergencies
- In many remote areas with little or no telephone service, families rely on CB radios for basic day-to-day communications. Many rural police and sheriff's organizations still monitor CB traffic. In a number of states, highway patrol officers install CB units in their patrol cars with the blessing of their agencies. However, may departments that used to monitor channel 9 have given up the practice. REACT groups in the area may still be monitoring.
- Unfortunately, the general public has not paid much attention to this "standard" and channel 1 is just as full of chatter as the others. It is important to note that the channel numbers on each radio are not always interchangeable between older radios with fewer than 14 channels. The chart below shows the frequency relationships for many 2 and 14 channel radios. Single channel radios are usually on channel 1, which corresponds to channel 1 in the 14-channel units.
- Operating a GMRS station will require a low-cost system license from the FCC. You can apply using FCC Form 574, or apply online. FCC online licensing information can be obtained at www.fcc.gov . System licenses are currently granted only to individuals. A system includes any and all radios operated by family members, and may include fixed, mobile, and repeater equipment. Use under the license is restricted to members of the licensee’s immediate family. Licenses to entities other than individuals are no longer issued, but non-individual entities licensed before July 31st, 1987 may continue to renew their licenses, and may not increase or modify their use.
- Calls can often be received from out-of-town but not made across town.
- You may recognize some of the more common ones, such as 1993, which covers a multitude of chemicals including road tar, cosmetics, diesel fuel, and home heating oil. You may have also seen placards with the number 1203 (gasoline) on tankers filling the underground tanks at the local gas station.
- The National Fire Protection Association (NFPA) has devised a marking system to alert firefighters to the characteristics of hazardous materials stored in stationary tanks and facilities. This system, known as NFPA 704M, can also assist citizens visiting a site in identifying the hazard presented by the stored substance. Use of the system is voluntary, unless specified by local codes. OXY means this material is an oxidizer. It can easily release oxygen to create or worsen a fire or explosion hazard. The symbol W indicates a material that reacts with water to release a gas that is either flammable or hazardous to health. If the material is radioactive, the usual tri-blade propeller symbol for radioactivity will appear.
- In an emergency, however, the FCC rules are suspended, and you may use whatever means of communication are necessary to protect life and property.
- Once you have the information, advise all persons on board to don life jackets, and contact either 911 dispatch or the closest Coast Guard facility by phone. In some cases, a local fire or police boat may be able to respond more quickly than the Coast Guard, who may be some distance away. Identify yourself as an Amateur Radio operator relaying an emergency message. Pass on all the information that you have gathered and assist as requested. Provide your name and phone number or other means of contact so that responding local public safety agencies or the Coast Guard may reach you if needed. It is possible that you are the only station that can communicate with the distressed vessel.
- Each type of message should be sent using the most appropriate mode, taking into consideration the message's contents, and its destination(s).
