Review of Cobra CXR900 FRS/GMRS Radio.
FCC ID: BBOCXR900
Power output: (ERP)
2.24 Watts High-GMRS
.49 Watts Low, FRS
This is an increase in power over comparable 2008 Models.
This model is approved for USA use only.
A GMRS license is required for use on all GMRS channels (15-22) and for high/medium
power on shared FRS/GMRS channels (1-7)
Cobra’s 2009 Top of the line model has some interesting feaures and functions.
CTCSS and DCS Tones/Codes for interference elimination
NOAA Weather Radio
“Rewind Say Again” function.
Key lock to prevent accidental changes
This top of the line Cobra model includes what you need and want. It is full featured
I will just address some important features or unique features not found on other models:
This model has full CTCSS and DCS for interference protection from radios not set to
your specific code.
Operation is fairly easy if you read the manual. The only confusing issues are
memory settings. They are only slightly confusing and are easily figured out.
All functions are menu-driven and listed in order.
You can scan all channels, only memory channels, or CTCSS/DCS on a specific channel.
The scan function does NOT have lockouts. This can be overcome by simply programming
channels you like into memory and just scanning these.
You may program up to 10 memories, which can also contain CTCSS or DCS codes.
“Rewind Say Again”
This is a 20 second digital voice recorder. Use it how you like, in 3 ways.
Record a personal reminder for later playback. Record activity on a channel, or
Record something then have it transmit on the air.
You have 20 seconds to play with. It will record each message in sequence, newest first on playback. Older
messages will “fall” off. Very interesting function. It could be useful.
Performance… THE REVIEW
Battery life: They say 12 hours. I say a minimum of 24 hours. I can guess you could get
2 to 3 DAYS on a charge, depending on use. Cobra uses the highest rated battery
pack on the market, and the only Lithium Ion I am aware of. These radios have
the power behind them.
Transmit power is over 2 watts. My range evaluations again keep them at the top
of the list.
House to car: 1.5 Miles
House to person: 1.75 miles
Person To Person: 2 miles
Car to Car: .75 mile
These test were done in a suburban environment with houses, trees, etc.
The car to car test was done on suburban city streets.
Audio: Volume is good for average use. Noisy areas may require a headset. Received
audio is crisp and clear, considering small speaker size.
Vibrating Page: It could be stronger, but it should work if held close.
All in all a great radio. The only improvements I’d make would be to have
the scan mode automatically detect CTCSS/DCS tones in the main scan, and let you lock out
channels “on the fly” during the scan.
Based on my pervious experience with Cobras, they are right on the money
I recommend these radios.
