heavy radio use

It’s that time of year when radios are going to be put into heavy use

Many businesses are now in their busiest season, while others are just gearing up, 2-way radios are getting heavy use. Now is a good time to assess what you have, checking over your radios, batteries, chargers, etc.

Do you have radios that are in need of battery replacement Motorola Impres Batteriesor maintenance? A quick check of the battery and charging system can save many headaches done the road. You probably don’t need reminded, but something as simple as cleaning your battery contacts with a pencil eraser can improve your chargers’ efficiency.

TIPS:

Swapping a known-good battery into a troubled radio can let you know if you have a battery or charging problem. Another piece of advice is to check your battery date codes.  The life expectancy of a NiCd battery is 18-24 months, NiMH and Li-Ion are around 14-18 months. If you have good charging habits and treat your battery well, you may get up to 3 years. At the end of the battery’s life you will start to experience problems with the radio such as static, short business day, no or intermittent transmit. If you use an old battery long enough, it will eventually begin to harm the radio, resulting in a need for repair. Simply replacing an old battery would be about half the cost of a radio repair. Our advice… don’t ignore battery date codes.Motorola battery date code

Chargers take their share of punishment. It is wise to assess your chargers when you are check your batteries. Look in the charger cup, do you see dirt and debris? If so, clean it out with a soft cloth, followed by gently cleaning the charge contacts with a pencil eraser. Check your wall transformer, they are known to burnout much a like a light bulb. When replacing charger transformers keep in mind they are not mix-n-match, you must use the appropriate transformer for the charging tray. Replacement chargers and individual components are usually available for most radio models.

Ever think your radios’ range is getting poorer? Check your antenna. If you can see copper coils when you bend the antenna, or if the top cap is missing, you need to replace the antenna. Use the correct antenna for the radio. The original antenna which came with the radio was designed to work with the radio. Swapping antennas can cause range problems, or result in the need for repair. Some model radios have stubby antennas available, keep in mind these can reduce your range by up to 2/3s. If most of your work is nearby, they may be a good option. However, if you do a lot of work at the edge of your full range, stay away from stubby antennas.

In the event, none of these tips seem to alleviate your radio issues, your radio may be in need of the radio repair center. We have a radio repair form that is easy to fill out. Just put it the box with the radio and we will get the unit repaired and back home to you. We offer a 5-7 day turnaround on most models.

2-way radios vs cellphones

Cellphone vs Radio

Non-radio users often ask why would someone use a radio instead of a cellphone. Here a few answers:

1) When you need immediate ability to communicate on-site to one or many at the press of a button. Two-way radios are the most reliable method.

2) No monthly bill. No minutes. (unless you connect your radios with a trunking tower system)

3) Durability. Business radios are designed to go a 40-hour work week. Many are rated for resistance to moisture, dust, and humidity. They are made to be a workhorse.

4) Using handheld radios for on-site communications can keep workers on task, and prevent the abuses seen with cellphones. (No calling home or surfing the web on a 2-way radio.)

5) Longer life expectancy. Most cellphones last 2-3 years at best. Business two-way radios typically last 5-7 years, or even longer if you have them serviced as needed.

2-way radio board6) Business radios are usually repairable at the radio repair center for less than half the cost of a new radio, while cellphones usually require replacement.

These are just a few thoughts to ponder.

There are situations where cellphones are ideal. But in the situation of public safety, business or on-site communications, radios still give you the best all around solution.

more tips on better range

2-Way Radio CustomerHere at the radio repair center we get many questions about radio range (talk distance). Typically a handheld business radio will do 2 miles line-of-sight or as far as the radio can see. Several factors interfere with range, including but not limited to: curvature of the Earth, obstacles, height and placement of antenna, position of the radio, and using the correct antenna for the radio.
Range tips:

  • 1) Holding the radio upright with the antenna straight up gives you the best range. Tilting to the side, as if talking on the phone, will reduce the range by up to 2/3s. This will cause transmissions to drop out, or be very staticky. Just remember: Perpendicular to the ground is best!
  • 2) The body fluid of the person wearing the radio can absorb part of the range.  If you’re a little bit round in the middle, your radio will not work as well as your pencil-thin co-worker. You can compensate by wearing the radio higher your body. Maybe in a shirt pocket or with a chest pouch. Height and placement of antenna determines range.
  • 3) Use a good quality fully charged battery. It takes more energy to transmit than to receive. Using a good battery will do wonders to clear up static, making your transmissions clear.
  • 4) Use the appropriate antenna for your radio. While stubby (short) antennas may be available for your radio model, keep in mind these will significantly reduce range. If you are working in a close proximity, they may work wonderfully. However, if you are expecting to transmit a long distance, go back to the original standard length antenna.
  • 5) Check your antenna for damage. If you can bend the antenna and see the coils or if the top cap is gone, it is time to replace the antenna. This may do wonders for your range.
  • 6) Get your radio tuned up. Electronic components inside your radio age over time and the radio will not function as well as it did new. Getting your radio tuned and realigned will bring it back to factory spec, or as close as one can get with an older radio.

radio range

Radio Repair CenterHere at the radio repair center we occasionally get questions about the range of a 2-way radio. Below are some simple answers to basic two-way radio range questions:

Portable radios generally will talk radio-to-radio, line-of-sight up to 2 miles. Once you start putting obstacles between the radios you will shorten your range. Even the body fluid of the person wearing the radio on their hip will absorb some of the range. Higher wattage radios will have a slight increase in range and a significant increase in clarity of transmission on the outer fringes of your range.

Mobile radios, such as those mounted in vehicles, will generally talk “radio-to-radio” 8-10 miles depending upon the obstacles and the terrain.

Base stations will generally talk approx. 8-12 miles. (referencing a simple base station where you use a mobile radio, power supply and outside antenna, aka a control station.)Contrary to popular belief wattage does not determine distance. Antenna height and placement determines distance.

  • Increasing Range:
  • 1) Hold your radio perpendicular to the ground, not slanted like you would hold a phone. This problem alone could decrease your range 30-50%.
  • 2) Don’t shout CB-style, shouting reduces talk-range on industrial-type radios.
  • 3) Be certain you are using a good, fully-charged battery.
  • 4) Check your antenna. Any exposed copper coil or weather checks which expose the coil when bending are a sign your antenna needs replaced. Also, keep in mind, use of a stubby antenna will reduce your range. The best antenna for a radio is generally the standard antenna it came with.
  • 5) And the technicians in the shop will tell you… have your radios serviced every two-three years to maintain peak performance.

Looking for even more range?

You might be in the market for a repeater, or have need to connect with a local repeater or trunking system which is already in place. But first, try bringing your radios to optimum range by following the above tips.

fishing license…

Motorola DTR700Here in the Midwest it is the time of year to renew our annual fishing permits. Just finished doing one online today.  (A new modern convenience.) Getting the permit made me think about how many things we do which require a license or permit… fishing, hunting, driving… and two-way radio transmitting. If you use a two-way radio, chances are you need to have an FCC license. While there are a few license-free frequencies in the USA, most businesses using radios need a license.

Radio users who were affected by the FCC narrowband mandate needed to be have a license modification done in order to keep their existing frequencies, and add the narrowband version of their frequency to their existing license. You can do this yourself at the www,FCC.gov website OR you can use a licensing company to take the headache out of the process. Either way, we suggest you don’t procrastinate, as the process will likely bog down as we get closer to the deadline and droves of radio users try to slip under the wire. Be an early adopter of the change. You won’t regret it.

LICENSE-FREE:

There are 5 license-free VHF frequencies known under the nickname MURS (multi use radio service).  Some users are opting to move over to one of these frequencies. While this will work for some VHF users, this will not work for those of you on UHF.

Also in the license-free arena are the 900 MHz radios such as the DTR700.  These new radios are digital, have much clearer transmissions, and more range than a VHF or UHF radio. If you are looking to replace your radios, this would be a great direction to go. The DTR700 can even do simple test messaging. We’re really impressed with this model and think you would be too.

As always if you have any questions give us a call here at Delmmar Communications, 800-872-2627. We’re always happy to help. In the meantime, hope you can take some time to enjoy the simple pleasures such as going fishing.

we service what we sell

Delmmar repair customers 2-way radio boardcan be assured 90% of the two-way radio models we offer are serviceable/repairable radios. Our highly trained technical staff repair most models of Motorola, Kenwood and Vertex radios. We do component level repair, replacing common failure parts, other needed parts, then realigning and tuning your radio to bring it back to its peak performance. If you send your battery or other accessories, we can test their functionality while they are at the radio repair center.

You might be thinking “What about the other 10%?”

Some radios are produced with out parts or schematics becoming available. We offer batteries and accessories for nearly all of these models, but repair is not an option. For the first few years the manufacturer will offer a warranty or factory repair. Past that time, it simply need to be replaced. When purchasing a new radio it never hurts to ask about future repairability.

Radio repair is typically less than 1/2 the cost of purchasing a new radio. Delmmar techs will continue to repair a particular radio model as long as parts remain available.

If you have a radio needing serviced you can fill out a radio repair form and send it to us. We have a 5-7 turnaround on most models. Questions? Give us a call here at Delmmar Communications, 800-872-2627. We are always happy to help.

water resistant radios

We often hear the question, “Is this radio waterproof?”

Truth is most radios are about as waterproof as your television. Electronic components and water just don’t mix. Then along comes a group of water resistant models. These radios are not waterproof, but are far superior in water resistance, and worth of mentioning.

Motorola XPR3300e is rated IP67 for moisture protection. Unlike other two-way radios, the back half of this radio is the battery pack. There are no openings to get inside the radio or see the component board. Being more of a sealed unit is what gives this radio the advantage over moisture. The IP67 rating tells us this radio has been tested for Immersion, up to 1 meter (3 ft 3 in) depth for 30 minutes, and passed the test. Additionally this radio is much better at keeping dust, dirt, and humidity out.

And yet a step better in water resistance… the Motorola XPR7350eXPR7350e is rated IP68 submersible. This radio, when used with the appropriate IP68 rated battery, passed tests submersing it in one meter of fresh water for longer than 30 minutes. While we don’t recommend trying this at home, this radio is the closest to waterproof you will find in the Motorola line. If you work in extreme conditions, this radio may be the one for you. Click this link to see the XPR7000 series brochure, which describes more about the radio.

Depending on your radio model there may also be a water-resistant remote speaker mic available. These are also rated to be moisture and/or water resistant. If you have lost radios or accessories to moisture, you should consider getting IP67 or IP68 rated radios/accessories with your next purchase.

And we would be amiss if we did not mention some basic information on what to do if your radio encounters water:

  1. Remove the battery. (Do not turn on or try to use the wet radio, as this could cause further damage.)
  2. Thoroughly dry the radio. You can use a towel on the exterior and battery compartment. If you feel the water has intruded further, use a blow dryer on a low setting to air dry the radio.
  3. Get the radio to a radio repair center ASAP. The longer you wait, the more likely the radio will grow corrosion, and be deemed non-repairable.

We’re here to help, and do our best to bring your radio back to good working condition. If you have questions give us a call here at Delmmar Communications, 800-872-2627. We are always happy to help.

mobile radio failure parts

Motorola hand micIt’s the hand mic!

User-interface items on any type of 2-way radio are the most common to fail. The hand mic on a Motorola mobile radio is no different. The coiled cord gets stretch repeatedly, the PTT button gets pressed numerous times a day, and in general the mic gets tossed around during the work day. This are all things which eventually fail.

If your radio is not transmitting one of the simplest forms of troubleshooting is to try a known good mic on the radio. If this doesn’t solve the problem, the next step is to check your antenna connections, and your antenna itself. Either one of these items can cause lack of transmit. Note: Antennas can become loose, coax can get pinched, the rear connection on the radio can become loose. These are all common things.

2-way radio boardIf you don’t find the problem in the hand mic or antenna, you may have a radio in need of repair. The Delmmar radio repair center can look at your mobile radio and determine if it is in need of repair. There is a flat rate fee for nearly all models of mobile radios. Send your hand mic along with the radio and it will be tested also. Radio repair is typically less than 1/2 the cost of a new radio.

Hand mics for the most part are non-repairable, but replacement mics are usually reasonable in price.

lemonade

Motorola radio in need of repairWith Summer here we often think of lemonade. Here at the radio repair center it seems we are often tossed a bag of lemons (broken radios) which we promptly squeeze and create lemonade, repaired radios. This little yellow radio arrived one day in the saddest of condition. We couldn’t help but take notice of his well-worn exterior, not to mention the funky mess with the taped down antenna. (Couldn’t have been talking too far with this one.) No doubt this guy had been working hard for several years. His owner had finally decided it was time to get an overhaul. Happy to report, the little yellow radio was repaired and sent home looking good as new. Now that is what we call lemonade!

Hope your Summer is full of lemonade moments, both literally and figuratively. If you have questions about radios or radio repair, give us a call here at Delmmar Communications, 800-872-2627. We are always happy to help.

Note: The above pictured Motorola Spirit radio model, as of 2019, is no longer repairable due to parts nonavailability.
