Effective Communication With Long Range Walkie Talkies

When we found this post we were so pleased, having searched for over one year for this, finding it on this website was an thrilling time for me.

2 way radio discountTwo way radios are used for communication purposes. They let a user send as well as receive signals over different channels. These radios find use in variety of applications. These radios use radio waves for communication and these radio waves have different frequencies. Therefore, two way radios operate on different frequencies. These frequencies may differ from one place to another. Also the transmission rate depends upon the frequency that the radio uses. When low frequencies are used, data transmission can take place over a short distance. In case a high frequency is used, data transmission takes place over a larger distance.

Long range radios are a variant of the two way communication radios. These radios are called long range because they operate on a high frequency. These radios are also called HF radios. They use frequencies in short wave bands which range between 3 MHz and 30 MHz, where MHz stands for mega hertz. Hertz is the unit in which frequency is measured. These radios can transmit signals over very long distances. The long range radios can also operate on Very High Frequencies (VHF) and Ultra High Frequencies (UHF). These long range radios can work over a very large distance and can transmit signals very clearly.

The radios can be used for various purposes. They are generally used for communication in airplanes and ships at sea. These radios are very popular in military organizations where they are used for two way communication. These two way radios can even be used in remote locations where cell phones cannot be used because the required infrastructure and frequency is not available.

The radios can even be used for transmitting voice signals very clearly over long distances. For this purpose, these radios are equipped with single side bands. These radios can even transmit digital data from one computer to another. This is the main reason of these radios becoming very popular in the computer industry.

For 2 way radios, very high frequency (VHF) signals are considered better because they have better penetrating powers and can be easily used in any type of terrain. Also very high frequency signals can travel longer distances as compared to ultra high frequencies. These log range Walkie Talkies can be conveniently used in indoor as well as outdoor applications.

One problem with HF radios is that for the transmission of data over long distances, these radios need very big antennae. This makes it difficult to handle these radios conveniently. When these radios have to be used in vehicles, the big antennae pose a big problem as they cannot fit into the vehicles easily. It is for this reason that long range radios are not considered fit for use in vehicles.

The two way radios operate in a straight line of sight and therefore are not very effective where the terrain is not plain. However, in spite of their few drawbacks, the two way radios have become very popular and are widely used for many applications across the world.


Equipment failure forces early switch of fire departments to digital system

When we found this article we were so pleased, having looked for over a year for this, finding it on this website was an thrilling day for yours truly.
A radio equipment failure Thursday forced the Shawnee County Emergency Communications Center to switch several fire departments over to its new digital system earlier than planned, an official said Friday.
Capt. Lance Royer, director of the Emergency Communications Center, said in an email a failure in 2 way Radio equipment providing the link between the 911 center and its master site for the older analog system necessitated a switch to the county’s backup plan. The center had to use control stations for its 911 center and fire units in the field, Royer said.
Royer said control stations are radios that remain stationary in the Law Enforcement Center and are attached to an antenna outside the building. They serve as a backup if the dispatch console fails, he said.
While the county already had deployed new 2 way radio units to the Topeka, Mission Township, Shawnee Heights and Soldier Township fire departments, Royer said, they had been using those on the old analog system because four rural fire departments hadn’t yet received the new radios.
“We intended to earmark a date to ‘go live’ for all fire agencies,” Royer said.
But because of Thursday’s system failure, the county decided to move the departments with the new radios over to the new P25 digital radio system immediately.
The other four rural fire departments — Dover, Auburn, Silver Lake and Rossville — still are using the analog system communication to the 911 center using its backup plan, Royer said.
The county will issue new portable radios to those remaining departments next week, and they will move onto the new digital system, Royer said. At that point, all Shawnee County public safety agencies except American Medical Response ambulance service will be functioning on the new digital system.
Royer said AMR is currently programming its radios and soon will make the switch to the new system.
Launch dates for the digital communication system have been pushed back multiple times this year. It was initially expected to launch by the end of March, but at that time new radios were still being installed in emergency responders’ vehicles.
The digital system from Motorola Solutions Inc. cost $12.1 million, according to Capital-Journal archives. Officials said the system would replace a 15-year-old analog system that was outdated to the point where Motorola could no longer repair some equipment that was broken.
