My son just bought the above reference product. He proceeded to power it up by connecting to a bench inverter that he uses forhis other radios/scanners. Nothing happened. He checked the in-line fuse and it was blown. After replacing the fuse he decided to try another power source. The unit was connected to a car battery. Again, nothing happened except a small puff of smoke from the rear of the unit and another blown fuse. At this point he decided he needed some help. I understand there is an internal fuse on the circuit board. Is that easily accessible/repairable?

Re: Motorola CDM1250 UHF Radio
Renard, just offhand without see'ing the unit, I'd say that something got sparked wrong in the hookup process. The taletell "puff of smoke" tells me the protection circuit or protector diode got "smoked" in the process. It's more than a fuse now, the protection circuit is blowing the fuse, to stop further damage. I'd say that, at least the protector diode needs changed and to check out for any other damage. Probably need a good tech to visually "check" the unit thruout. Definately needs to have it put on the meters and guages to fix all the damage at one time, something that cannot be done by talking you thru it,,, Mechanic

I have never used a scanner of that type but I have seen them in use and know the principle of operation.
If you are certain the radio is working and have checked with the instruction manual that you are operating it the correct way with any squelch control turned down and the volume turned up there should be a loud hissing from the speaker indicating the radio is ready to receive as soon as it is either tuned to the specific frequency of a station by direct entry or by scanning one or more bands of frequencies.
If there is no hissing noise it is possible the audio output is faulty or the aerial is not connected or the radio is otherwise faulty.
If the hissing noise is present and powerful and still nothing is being received it is possible there is nothing to receive or a more powerful aerial is needed.
It is worth noting many scanners available in the past tended to scan bands of frequencies in the upper and lower vhf bands where the aircraft, marine and emergency services radios operated. Since those days many of those services have moved their communications into the UHF bands leaving the vhf bands relatively empty.
Hi, first, you can only listen to analog radios on this scanner, so if you local or state public servants went to digital, you are out of luck. You can still receive National Weather Service, most railroads, ham radio operators and any small town police and fire that have remained on analog VHF and UHF. Do a Google search and you can get the instruction book for the radio. As far as channels, search for Radio Reference dot com and search for your state and county. That will list the channels to enter into your radio. Good luck and have fun.
My icom 706mk2g does no give me hf power on the hf bands but on uhf is working wel.
On the s meter the last blok is turn on.
Reseiver is working wel.
Wat can it be?? Transistor Finals broken???
The two srfj?
Your scanner does not receive frequencies between 54 and 137 MHz, and there's nothing you can do to enable reception in that block. Your only option is to purchase a scanner with air band coverage. Here are the reception ranges of the BC-60XLT-1:
29.0-29.7 MHz 10 Meter Amateur Band 29.7-50 MHz VHF Low Band 50-54 MHz 6 Meter Amateur Band 137-144 MHz Military Land Mobile 144-148 MHz 2 Meter Amateur Band 148-174 MHz VHF High Band Above bands in 5 kHz steps 406-420 MHz Federal Government 420-450 MHz 70 cm Amateur Band 450-470 MHz UHF Standard Band 470-512 MHz UHF "T" Band Above bands in 12.5 kHz steps
Need the manual for your scanner? You can download and print it, at no cost, here: http://www.uniden.com/pdf/BC60XLT-1om.pdf
Its so easy to use you really don't need a manual for the Uniden BC 142XL scanner.
Turn it on. Push the MANUAL button to stop it from scanning.
Push number 1, then push MANUAL again. This should leave you on
Using the keypad enter the frequency you want to monitor, then push
E. Press REVIEW at anytime to see what frequency is programmed
there. If the review button flashes 000.0000 on the display, you might be entering an invalid frequency. Refer to the frequency coverage list below.
Push MANUAL to step to channel number two. Enter the frequency. Push E. Push MANUAL to step to channel three. Repeat this process until
all ten channels are programmed, or you've run out of frequencies to
Push "SCAN" to start automatically scanning the frequencies. The
radio will stop when it hears someone talking, and resume scanning two
seconds after the conversation has stopped.
20 to 29.7 MHz (10 Meter "Ham" Band)
29.7 to 50 MHz (VHF Low Band)
50 to 54 MHz (6 Meter Amateur Band)
136 to 144 MHz (Military Land Mobile)
144 to 148 MHz (2 Meter "Ham" Band)
406 to 420 MHz (Federal Government Land Mobile)
420 to 450 MHz (70cm "Ham" Band)
450 to 470 MHz (UHF Standard Band)
470 to 512 MHz (UHF "T" Band)
