Mobile Radios

Mobile Radios

Mobile Radios have a distinct advantage over fixed base radios in that they are smaller (easier to conceal), they have almost the same features and options as fixed base radios, and they can be used as fixed base radios simply by connecting them to readily available 12 volt power supplies. Mobile radios and even fixed base radios can readily be used for portable operations.

Mobile radios will generally operate in the VHF/UHV1 range and are best for localized operations. Depending on the gain of the antenna used in mobile operations the area of coverage for mobile radios can be anywhere from 1 to 5 miles. Should a survivalist incorporate HF or High Frequency radio in their communications gear then they can expect to dramatically expand their area of coverage.

Of particular interest to those who want a comprehensive communications system is the fact that quite a few amateur (ham) radios incorporate HF & VHF. For instance, the Icom model IC-746PRO covers the amateur bands between 1.8 and 29.7 megahertz. Along with these frequencies theIcom IC746PRO HF/VHF/UHF IC-746PRO has a general coverage receiver which encompasses the frequencies between 0.030 and 60 megahertz. An additional receive only band of 108 to 174 megahertz also comes standard in the IC-746PRO. One more attractive feature of the IC-746PRO is that in contains an onboard antenna tuner. An antenna tuner’s function is to insure the antenna connected to the IC-746PRO is matched (tuned) to its optimum. Antenna tuners protect the transmitter of radios as well as improve the received signals. Even though the IC-746PRO is considered to be a fixed base radio, it is well suited for mobile and/or portable operation.

Portable Operations

We touched briefly on using mobile radios and base station radios in portable operations. One might wonder about the differences between that of mobile radios and portable radios. The radios themselves are no different when it comes to portable operations. It is the surroundings that differentiate between fixed base, mobile, and portable operations. Portable operations generally use a large and/or more permanent antenna system than a mobile radio would require. Portable operations generally are running on either generator or solar energy as the power source for the communications equipment. The antennas used in portable operation tend to be either verticals stuck on a pole or a series of tuned wire antennas strung between structures such as trees.

No matter what radio gear a survivalist chooses they need to consider the probability that they will be using mobile or portable radio setups at one time or another.


1VHF/UHF indicates the radio equipment operates in the VHF, Very High Frequency, or UHF, Ultra High Frequency, ranges.


Alinco Radio & Communications Equipment

Slogan: “Around the clock, around the town, around the world.Alinco is a company known as a manufacturer of communication devices for the amateur radio bands and for business use also. We’ll cover and little bit about the business use of Alinco radios first even though they have little use to a prepper and/or survivalist.

Alinco business band radios

Alinco business band radios are best summed as portable and mobile VHF and UHF radio gear and power supplies as well. Their current business band radio catalog shows a good selection of handheld radios, mobile radios, and at least three different communications grade power supplies. And they also have a linear power supply available in two different models. That covers as much as we need to go into concerning business band radios.

Alinco amateur radio equipment

Alinco’s amateur radio offerings is similar to its business band offerings except for the HF transceivers and shortwave receivers. As of this writing they offer two different HF transceivers which can be used as either a mobile or a base station depending upon the needs of the prepper or survivalist. We’ll start with the model designation DX-SR8T/E which is listed as an “All-mode Desktop Transceiver.” This amateur band transceiver covers 1.9 megahertz up to 29 megahertz using the following modes: SSB (which is normally referred to as “phone”), CW (the amateur radio shorthand for Morse code), as well as AM/FM. This radio is obviously a clone of the popular Icom IC-718 radio. Their next offering is pretty much an upgraded DX-SR8T/E since it pretty much shares the same model number: DX-SR9T/E. The DX-SR9T/E has one feature that the DX-SR8T/E does not have which is SDR. SDR stands for software defined radio. Whether or not SDR is attractive or can be used SHTF scenarios is debatable. One can only guess SDR would be a personal preference on the part of the prepper. Survivalists may or may not care about the inclusion of SDR in this Alinco transceiver. Currently Alinco offers five different “mobile” amateur radio transceivers:
  • DR-03T / DR-06T – TX(T):  DR-03T: 28~29.695MHz, DR-06T: 50~53.995MHz, RX(T):  DR-03T: 28~29.695MHz, DR-06T: 40~69.995MHz
  • DR135T/EMkIII Monoband Mobile/Base – TX(T): 144-147.995MHz (FM), RX(T): 118-135.995 MHz (AM), 136-173.995MHz (FM), TX&RX(E): 144-145.995MHz
  • DR-235TMKIII 25W FM Mobile/Base unit – TX: 222.000 – 224.995 MHz, RX: 216.000 – 279.995MHz

Communications Receivers

Rather than blathering on about the features of these communications receivers we felt it best to just put a link to them on Alinco’s web site. Although communications receivers aren’t all that attractive in SHTF scenarios they could be of some use in base station activities.
