The usable range of any radio systems depends on many factors.
    1- your two-way radio condition: ( RF power / sensitivity )
    2- The antenna connected to this radio
    3- the terrain and obstacles  between users. where the race track is situated.
Since there is not much you can do about the race track layout and obtacles,
you can improve your overall radio performances by cheking your antenna cable and connectors
and upgrading to a higher gain antenna.
the ELITE 3Db antenna is a good choice. The ultimate and revolutionary CAK-70 is the best you can get on the market for road courses.
Make sure your radios are bench checked and realigned to factory specs by Racing Radios int.
Since portable radios have a limited RF power of 5 watts, the antenna choice is crutial for good performances.
Remember that mobile two-way radios like the CM200d or CM300d can range from 25 to 45 watts of output power
increasing the range of a race car transmission ( TX).

For most of the race teams running on small oval tracks or superspeedways, Complete systems with portable radios like Motorola BPR40 , CP200 , CP200d  can deliver good performances.
On the other hand, the road courses are a bit of a challenge for Racing Radios systems.
some radio setups with portable radios in simplex mode connected to high quality external components
( Antenna/ in car harness ) will cover most of those.
But when it comes to Layouts in wooden areas and urban streets, a more powerful Mobile radio will be required
in the race car and pitlane to ensure constant communications between the crew and the driver.
Since most open wheels race cars like F2000 / F3000 or F1 have no room for a bulky Mobile radio,
a pitlane repeater or mobile radio with eleveted antenna setup is the way to go. 

Nowadays most of the pro racers have custom molded earpeices since they offer the best noise cancelling features
and comfort.
Generic earpeices are shaped for the average human ear. The soft silicone compound make those very comfortable.
Foam earpeices are cheaper to buy and will fit most of the earshapes and are perfect for moderate noise usage.

In order to get custom molded earpeices you have to supply your earprints to us.
You can either go to your closest Hearing Aid doctor and get your prints done and ship those to our office.
or drop by Racing Radios Service Trailer 2021 Schedule to be found at most major racing events in eastern canada.
We manufacture earpeices with an inhouse  3D process to ensure quality control and timely delivery.
Turnaround time is 7 days or less. 

Driver’s helmet kits are assembled with various components for best performances  in specific situations.
First option is the Microphone.
Most of microphones used in racing comes from the military M101  style and the GENTEX style dynamic miniature line.
The noise cancelling feature of both models is helping to eliminate incar engine noise . The GENTEX style is very popular due to it’s small size and high efficiency.
Second you have to choose between a straight  or coiled cord  cable from the helmet to the incar harness connector.
The actual trend is for coil cords in order to give more freedom of movement to the helmet.
we beleive straight cords are safer during an emergency exit  from the race car since the helmet will unplug itself
in the process. 

Push to talk switches are basically all the same. They just come in different shapes.
1- The Velcro type wraps around the steering wheel or any other nearby objects ( roll bars / Shifter )
    for appropriate positionning in the cokpit.
2- The heavy duty hole mount PTT switch are mounted on steering wheels
     and requires a good tumb pressure to activate.
3- The miniature Hole mount PTT switch is also mounted on steering wheels , have a lower profile design and requires        only a small tumb pressure to activate.

The incar wiring harness is the heart of your radio system.
It is exposed to a very hostile and noisy environment in a race car (ignition and all electronics )
The Racing Radios USA quality Radio harnesses were developped since the 1980’s
are manufactured in the US and they meet the highiest standards in the industry.
You can find those in race cars all over north america and abroad in all types of racing.
Do not settle for less.

YES, The racing Radios International  HCN7685 is designed to operate 2 radios simultaneously
with a 2 button belt PTT assembly.

Furthermore the HCN7785  model is a headset specially design to acomodate 3 radios 
(with a 3 button belt PTT assembly) for intense race management requirements.

Those 2 headsets also incorporate a scanner port to listen to race control.

The cheapest antenna is the very popular 1/4 wave rod (unity gain) tuned to 450-470 Mhz 
next level is the ELITE 3Db gain antenna wich increases the overall range of a radio system.
Best on the market is the CAK-70 antenna with it’s built-in ground plane.
this one is used by most pro racing teams all over north America.

The primary role of an antenna is to transform electrical energy into electromagnetic field
with minimum loss.
Remember a good and reliable feed line (coax cable ) is critical to carry the signal from the radio to the antenna
and that a bad radio antenna can anhihilate your entire radio system performances
if improperly installed and tuned.

Here is an overview of the Motorola commercial radios used in racing from oldest to most recent models:
P50 – P100 – GP300 – P110 – SP50 – P1225 – CP200 – BPR40 – CP200D – CP100d
NOTE: only the BPR40 / CP200D and CP100d are still manufactured by Motorola as of today

It all depends on the style of racing your team will be running.
most racing series on oval tracks and drag strips only requires portable radios to do the job.
see Racing Radios Oval tracks radio system 
Road courses race  teams usually run Mobile radios in the car and portable radios in the pits
see Racing Radios Endurance radio system
Formula cars are using portable radios and rely on a very efficient antenna to cover the whole track.

First thing to consider is the actual age of your batteries
and the way they were treated and stored over the years.
Ideally you should have your batteries tested by Racing Radios International for remaining capacity.
We consider any battery with a remaining capacity of 80% to be good.
To be on the safe side , batteries older then 3 years should be replaced.
As an example, a brand new mid capacity Motorola Battery with a transmit / receive / stanby  time ratio of 5/5/90
should last at least 6 hours. 

Analog FM radios have been around for decades in racing and have proven to be very reliable
in all kids of situations. They are very affordable and a good solution for teams on a budget
Most teams are now moving to DIGITAL radios for multiple reasons:
1- DIGITAL radios like the CP200D offers a better voice clarity due to the DSP ( digital sound processing )
circuit that eliminates most background noises.
2- DIGITAL radios also offers total privacy with FSK modulation and encryption options.
3- DIGITAL  voice process is able to reconstruct a weak audio signal  to increase the audible range in a transmissions.
4- DIGITAL modulation requires less energy from the battery ( 40% less )

Just keep in mind that some racing series do not allow DIGITAL radios.

Reprogramming two-way radios is $15,00 fee per units.
we can reprogram the following Brands and models either at the shop and in our service trailer:
Motorola older models : SP50 / P110 / GP300 / P1225 / CP200 / HT750 / EX500 / EX600 / HT1000 / MTX838
Motorola recent models : CP200d / CP100d / CM200d / CM300d / XPR6550 series / XPR5550 / XPR4500 / XPR4350 / BPR40 / 
Kenwood Analog : TK3302 / TK3120 / TK3202 / TK3160
Kenwood Digitals: NX320 / NX

ANR stands for ” Active noise Reduction ” 
A headset equiped with this feature will electronically cancel outside noise that reached your ears
and provide acoustic isolation for clearer audio from the radio.
An ANR headset will have the following extra components:

• a microphone that “hears” the sound levels that have gotten into the dome cavity
• electronics that will “process” that signal and relay it to the anti-noise speaker
• a speaker (also known as the “ANR driver”) that “adds” sound into the dome cavity

  Those Headsets are commonly used by crewmembers in all kinds of racing series around the world.
  They are defenitely the best headset you can get on the market today. 

Two-way radios are electronic devices that often requires mecanical repairs or more serious PC board components replacement. A broken Knobs / antennas and radio housing are usually unexpensive fixes.
on the other hand, a receiver sensitivity problem , PA replacement or RSM jack replacement can rise the option of buying a new and garanteed unit.
First thing first,
Q: how old is your radio ?
Q2: how much will it cost to fix it ?
