The Motorola HT1000 radio was a popular 2 way radio with police, firefighter and EMS personnel because it is rugged, small, easy to carry, has excellent voice intelligibility and is affordable. Although no longer in production, these radios are still popular today. It offers Motorola’s widest band range: 136 to 174 Megahertz on full band VHF mode. The HT1000 can also scan all its operating channels and can provide a broad range of signaling options. A problem for would-be users of the HT1000 is that proprietary Motorola software is required to program it.
1Request Motorola radio service software, also known as RSS, from Motorola’s business online site. You will have to register and agree to their terms of use contract.
2Power up your computer and go into DOS mode. You can use a DOS boot disk or restart your computer in Windows DOS. If you don’t work in DOS, you could end up corrupting the software controlling your HT1000.
3Switch your Motorola HT1000 off. Attach your RIB cable to your HT1000 and to your computer’s serial port. Power up your Motorola HT1000 radio.
4Open the directory where you copied the RSS, and start up the HT1000 file. Press enter to get past the first splash screen. Before programming your HT1000, make a backup of your current configuration by pressing F3 then F2 in the Get-Save-Clone menu, and finally F7 to save the configuration to your computer.
5Exit the Get-Save-Clone menu of the RSS by pressing F10. From the software’s main menu press F4 to reach the Change/View Radio Codeplug Data menu. You can use this menu to reprogram every aspect of your Motorola HT1000. Return to the Get-Save-Clone menu and press F7 to save the data your programmed.
6Return to the main menu and press F8 to go to the Program Data Into Radio menu. Press F8 again to proceed with the data writing to your radio. Once the RSS finishes copying the data, power down your radio and disconnect the RIB cable.

How Can Walkie Talkies Be Used During a Disaster?
Walkie-talkies are hand-held, 2 way radios that have been used for communication during disasters since World War II. In wartime settings, walkie-talkies were the only means of live communication for the troops back to their headquarters. Since then, walkie-talkies have become popular in the general population because they make possible two-way communication in areas not equipped with phone lines and electricity. Having a walkie-talkie can make a difference in life-threatening emergencies.
In a Disaster
Strategically place emergency kits that contain sets of walkie-talkies in easy-to-access locations. Train your workers in the workplace and your family at home in how to get to the walkie-talkies and use them in a disaster.
Walkie-talkies send messages to one another and don’t require a cell tower to relay signals. That makes them more reliable than cellphones in remote areas where it’s difficult or impossible to get a signal. More advanced walkie-talkie devices are two-way radios that transmit signals over the Family Radio Service (FRS) of the Federal Communications Commission.
Schools, commercial businesses and public facilities are sometimes required to keep a set of walkie-talkies and extra batteries available for communication during a disaster. Each household should have a set handy as well.
Reach for the emergency kit containing the walkie-talkies when disaster strikes. Turn them on, tune into the radio frequency and try to reach someone on the other end. Give one walkie-talkie to someone in your family or group if your kit has more than one. Make sure the communication line is open between the two walkie-talkies before you split up to find help or to help others in an emergency.
Continue to communicate with the other walkie-talkie user and continue to establish a connection with someone outside the disaster area. Some walkie-talkie units are equipped to access the radio, allowing you to tune into a local radio station for updates in the case of a widespread disaster.

How to Develop Code & Communicate With a Scanner
1Purchase a scanner, which is a radio used to transmit information. Scanners, sometimes called police scanners or 2 way radios, range in price from $100 or less to more than $1,000, depending on their specifications. Less-expensive scanners work well for personal use, such as monitoring transmissions for hobby or personal safety. Units that are more expensive are used by police and fire departments to provide stronger frequencies and outputs that are more powerful. Most electronics stores and online auction websites sell scanners.
2Set up your scanner by following the instructions that came with the unit. Find frequencies for various agencies by searching the dial or by looking up the official frequency on the agency’s website. Consult RadioReference.com for a database of frequencies for organizations throughout the United States.
3Learn the communication code. Police codes use codes with the prefixes “10-” and “11-” followed by numbers that correspond to various situations. For example, “10-4″ means “message received.” Long-haul truckers use a different set of codes to communicate. In the language of truckers, for example, the term “alligator” means there is a blown tire in the road, and a “salt shaker” is a snowplow.
4Develop your own code for communicating. If you are using your radio to communicate with someone, discuss terms you would like to codify for your own radio language. Consider using the police or trucker codes as a base to work from when developing your own code language. For example, think of a nickname for the town you live in or a code word for the street you live on.
5Record your codes and distribute the information to others who will be using the information. You can do this with a notebook, computer document or online database, which all code users can modify when they think of a new code word.

How to Extend the Range of a Wireless Baby Monitor
1Attach a piece of metal to the baby monitor’s antenna. Cut a coat hanger, for example, and tape the long metal piece to the antenna. This wire or piece of metal can be any length but three to four inches should do the trick. This will help the simple 2 way radio’s gain, allowing it to have more reception. Do this on both monitors.
2Wrap the antenna and a piece of metal in aluminum foil on both baby monitors. This will help it receive signals from the other monitor better. Entirely cover the piece of wire with the aluminum foil.
3Place the baby monitor that you will hold onto as high as possible. While the monitor in the baby’s room must be near the baby so you can properly hear him, the higher up your baby monitor is, the better it will receive signals from the other monitor.

How to Troubleshoot a Uniden VHF Radio
Uniden’s Very High Frequency (VHF) radios are for marine applications. Uniden also make non-marine, 2 way radios for General Mobile Radio Service (GMRS) and Family Radio Service (FRS) but they are considered Ultra High Frequency (UHF) radios because they operate on frequencies higher than 300 MHz—the cutoff for VHF. Uniden’s marine application VHF radios are supplied in hand-held and fixed-mount variants.
1Remove the hand-held’s charger cable or take the radio off the charger stand when transmitting. The charger is supplying a low voltage and the radios are not designed to transmit while charging because the AC or DC adapter doesn’t provide enough power. If the battery doesn’t charge it’s often due to transmitting while charging.
2Change the batteries or recharge them if the radio won’t transmit on the five watt setting but will transmit at one watt. There’s not enough juice in the batteries to function at five watts.
3Extend the antenna to the maximum height if the Uniden VHF radio’s range appears limited. Try going out on deck to transmit with limited line-of-sight blockage.
4Eliminate any sources of electrical interference if, while scanning, the radio stops on a particular channel all the time. A quick fix is to press the up or down button to get the radio scanning again, but noise is the likely cause. Move out into the open. Switch off electrical and mechanical gear one by one and use elimination to try to identify the source.

Cobra PR-240 Specs
The Cobra PR-240 is a 2 way radio set that has been discontinued by the Cobra Electronics Corporation. It was replaced by a smaller, more powerful two-way radio. Parts and manuals for the Cobra PR-240 are still available. Anyone who gets a working used set will have a two-way radio set that works well, has a good range and holds up well.
Power
The Cobra PR-240 is powered by four AAA batteries. It has a five-mile range with a range extender which will pick up even very weak signals. That can be useful in wilderness settings where you are unlikely to get excessive squawk from other users. It operates at one watt output power. The radios can operate on traditional or rechargeable batteries, with a drop-in charger cradle available as an accessory.
Channels
The radio offers 22 channels; seven in the Family Radio Service, or FRS, frequencies, eight General Mobile Radio System, or GMRS, channels and seven shared FRS/GMRS frequencies. FRS is an unlicensed service provided in UHF that the Federal Communications Commission leaves open for short-range use. GMRS frequencies add more options and can operate at higher wattage, In some remote areas, the GMRS channels will give you the best range. The Cobra PR-240 also offers 38 privacy codes, which help reduce unwanted chatter from nearby users on the same frequencies.
Security
The Cobra PR-240 offers 38 privacy codes, which help reduce unwanted chatter from nearby users on the same frequencies, while protecting your conversations from others who may have similar radios. The radios provide a channel scan, which allows you to search for others on the air in an emergency situation. The auto-squelch keeps down background noise from other near-by frequencies. It is lit up with an LCD display for use at night and has a low battery alert.
