I don't know what this radio is, but perhaps I can help. First of all, 6 watts is output power and has nothing to do with receiving. With such a short transmit distance, my first suspicion is something very wrong with the antenna. Has the SWR on the antenna been checked? Let's start from there.

Have you tried a different michrophone. If you have then the radio will have either a cold solder joint on the main board or a transister has gone bad. The unit will require service at a local radio shop or send to Uniden Service center.

To troubleshoot: Unlock your keypad lock, then reprogram your radios to the following settings. (Check function after each change)
1) Shut off the Interference Eliminator (set to zero).
2) Turn off the Qt filter.
3) Vox setting to off.
By shutting off all the "bells and whistles" of the radio, you will take it back to being just simply on a frequency. If your radios do not communicate with one another then, or with your friend's radios, you have radio which is failing to operate.
If the radios do work in this simple mode. One by one add the special features back until you discover the culprit.
SOURCE: Some bands OK some not. No transmit, no readout on some.
its the problem of the frequency range its getting blocked at particular location.these can be solved by two options
1)first try changing the location of the unit from one corner to another corner.that should help to catch the frequency again if its getting blocked at particular location.this happens many times.but if changing the locan does not make any difference.then
2) get checked that the antenna of the unit is not catching the required frequency for the unit.so change the antenna also connect this external antenna as mentioned 50 ω (it comes wioth SMA Connector) that helps in catchinf the frequency.
you will get this at radio shack website. this will help.
-----------------------------
also in the unit there is a component which controls the frequency called microprocessor if that goes weak the unit slowly slowly stops receving the accurate signals and only the noise comes.so the micro processor in located internally in the left side.its a green and black colour mini chip circuit board.many times opening the unit and removing and cleaning the microprocessor and refitting it solves the problem but this is 50 --- 50 chance.
this all has to be checked what mentioned.
thank you for using fixya.
SOURCE: Remotes have poor range
Here is some information that may help you.
Limited range of your remote controls
could be related to radio frequency interference that comes from
something in your home or in the surrounding environment. Certain
electrical devices can radiate interference; this could be almost
anything that is plugged into an electrical outlet.
Please keep in mind that the device can
be brand new, or can be an item that has been in use for quite a
while. Also, the item may continue to function properly as far as
you are able to tell. The only problem with the item may be that it
has started to broadcast the interference, with no other symptoms
noted.
Some devices are more likely to
generate interference than others. This includes TV cable, cable
amplifiers, surge protectors, fluorescent lights, battery charging
devices (power tools, golf carts, etc.), anything that utilizes a
timer (sprinkler systems, lights, alarm systems, etc.), and a myriad
of others. If the problem seems sporadic, we can safely assume that
the device responsible for the interference is only being operated
during these times. Again, please keep in mind that the age of the
device does not determine if it is capable of broadcasting unwanted
interference. Any electrical device can be the source of the problem.
The first step is replacing the battery
in your remote. If the range on your remote does not improve, remove
the wall control wires from the overhead unit. If the range does not
improve you will likely need to replace the remote control. After
replacing the remote, or if you have other remotes programmed in to
the opener, and the range problem still exists, please proceed to the
Power Down test.
Multiple garage doors:
If you have two garage door units and
one is working just fine, you will need to start by unplugging the
good unit. This will help determine if the unit with no range starts
to function properly. If the range comes back to the bad unit then
you will need to replace the logic board on the unit that was
unplugged as it is emitting an RF signal that is over powering the
other garage door opener. If the range doesn not improve after the
“good” unit has been unplugged, replace the batteries and try
programming some additional remotes to determine if the existing
remotes are the issue. If the extra remotes do not have any range
then you would need to replace the receiver logic board in the “bad”
unit.
Power Down test:
To isolate potential sources of
interference, turn the circuit breaker off to the garage and plug the
garage door opener into an extension cord from another room. If the
range improves, then the interference is coming from a device in the
garage. If no improvement is seen follow the same procedure, this
time turning off the circuit breakers to your home, with the
exception of the garage and test the remote controls. If improvement
is noted, turn the circuit breakers back on, one by one, until the
range problem resurfaces. This will allow you to narrow down what
room the problem device is in. You will have to go from there to
isolate it further, by unplugging and re-plugging the items in that
room.
