We don't know what kind, model , etc. but it sounds like the driver is fine and you blew the final transistor which is about 2 to 5 dollars plus any service charge if you have some one do this for you. It is simple if you know solidering and electronics. First we need to know the model number and then hunt for a schematic.

Hope we can help you more.

I have qty 2 IC-V85 handheld radios i just purchased new. One of them is working as planned testing136.000. The second one shows transmitting when i push the button but doesnt transmit?


At the Factory, they program test frequencies into the radios. They may or may not transmit to each other out of the box. They assume all radios will be read, then programmed properly. The test frequencies may not even be the same. Never transmit from the charger. All kinds of bad things can happen. Glad to answer more questions, but first, what are you using them for?

I Want To Add Talk Back Mod To CB Radio


there is what is known as the Quick and Dirty way, to add talkback to almost any CB radio. You will need a 130 Ohm 1/4 watt resistor. Open the radio and find the two mounting points for the external speaker jack and PA audio jack, you will want to solder the resistor across from the Positive connection of the PA jack to the Ground connection for the External speaker jack. This will give you talkback, and eliminate any feedback when the microphone is held at a normal operating distance away, Just remember, (This could potentially damage your radio if done improperly, I will not be held liable for anything that you do to your radio.) However, when done correctly this is a perfectly safe modification, and will allow you to monitor your output audio, as it is being transmitted. You can adjust the size of the resistor to your liking, however, I do not recommend anything lower than 100 Ohm, as there will be more potetial for squealing/feedback.

My uniden hand held radios are transmitting but not receiving why???


Possible programming problem. Your receive frequency may not be set the same as your transmit frequency, or your PL code may be set differently between the radios. Check your programming.

Best regards.

W do I turn off squelch control on a digitech DC-1065 marine radio hand held 5 Watt


Hi David,

Before I try to give advice, I need more info.

I possess a Digitech DC1065 UHF 80 Channel CB hand held, so there seems to be some confusion here.

I live near Perth, Western Australia.

Firstly, How many channels does your radio have?

If the answer is 80, then what you have is a UHF CB, not a marine band radio.

Marine band is VHF with 87 Channels, in Australia that is, and the default channel is always 16.

Digitech are an Australian radio manufacturer, so you'll get great backup service.

If your radio is not defaulting to Ch16, then I am right about it being a UHF CB.

Therefore, it is useless for VHF anything, let alone Marine band.

I'm almost 100% sure this is a UHF CB in your possession.

Try this to prove me right please.

Reply to me with your Country and nearest city, I'll then be able to find a solution for you real quick, though I believe I already have.

Looking forward to your response.

Regards,
Peter

How many watts do midland walkie talkie xt20 have?


These are FRS/GMRS (Family Radio Service/ General Mobile Radio Service) radios. The legal power limit for FRS is 500 milliwatts - or 1/2 watt. GMRS on the other hand is limited to a much higher 50 watt level. The wattage you transmit determines if you need to have a GMRS license. Most GMRS radios are in the .5- 5 watt range however.

The likelihood of your XT20 being a 1/2 watt out on both FRS & GMRS is very good. For Midland (or anyone else for that matter) to produce a radio with a 1 watt output that can run on just 3 "AAA" batteries would be quite the feat! If Midland did do this, the radio's battery life would extremely short. To balance the needs of light weight and battery life, output power needs to be reduced.

Claims of 20 miles is crazy. If you had these radios on mountain tops 20 miles apart - with a clear line of sight between them - MAYBE - you could hear one on the other. This would need to be done under only the most ideal conditions. The actual distance you can expect to get out of a pair of any brand FRS radios in "real world" conditions (line of sight blocked by trees and buildings) is about a mile.

An FRS/GMRS radio limited to 1/2 watt output when used on a GMRS frequency that is close enough to access a GMRS repeater system could easily cover 20+ miles. The key here is having a license and access to the repeater. Repeater owners take a dim view of unlicensed users access their repeater.

Channels 1 thru 7 are FRS and GMRS. That is, if transmitting .5 watts, you can use it as FRS. If transmitting more than .5 watts, you will need a valid GMRS license.

Channels 8 - 14 are expressly for FRS. Only .5 watts transmit power is permitted.

Channels 15 - 22 are expressly for GMRS at any transmit power up to 50 watts. Even if transmitting .5 watts, you MUST have a valid GMRS license on these frequencies.

I know - more infor than you wanted and no vclear cut number for wattage - but there's no info on these radios on Midland's site or anywhere else that I could find. Good luck!

18 miles max range but actual it can transmit and


The reason for this is due to various possible conditions. The first being obstacles in the operation range of the unit. IE> hills buildings trees ect. This can greatly reduce the actual distance the unit will work in. The 18mile max is probably a rating that would apply in the best opt. scenario. You would have to be on a flat terrain with no hills or valleys,no trees or buildings for the unit to reach the max distance. In dense areas of trees,buildings or uneven terrian you wont even come close to these distances. Second: any unit RF unit that is held in your hand or close to your body does cause the antenna to detune to various degrees the amount that it does depends on how well the unit has been designed. The more it detunes the less resonated frequence is recieved and amplified making for a weaker signal. In conclusion for the best long range reception be clear of as much surronding interference as possible and as high a possible above any elevated terrian

Makes a squlesh sound like a CB radio when monitoring radio or transmitting


GMRS transceivers, yes - like CB radios, have squelch or threshold tuning circuitry. Without it you would be listening to an irritating hissing noise between transmissions, and the radios would not be able to scan. The big difference is that the squelch setting on a CB is adjustable, but it's automatic on GMRS sets.

Antenna mounting


according to FCC rules RULE 8 - Antenna Height
{A} "Antenna" means the radiating system (for transmitting, receiving or both) and the structure holding it up (tower, pole or mast). It also means everything else attached to the radiating system and the structure.
{B} If your antenna is mounted on a hand-held portable unit, none of the following limitations apply;
{C} If your antenna is installed at a fixed location (whether receiving, transmitting or both) it must comply with EITHER one of the following:
[1] The highest point must not be more than 20 feet (6.10 meters) higher than the highest point of the building or tree on which it is mounted;
or
[2] The highest point must not be more than 60 feet (18.3 meters) above the ground.
{D} If your CB station is located near an airport, and if your antenna structure is more than 20 feet (6.10 meters) high, you may have to obey additional restrictions. The highest point of your antenna must not exceed 39.37 inches (1 meter) above the airport elevation for every 109.36 yards (100 meters, 1 hectometer) of distance from the nearest point of the nearest airport runway. Differences in ground elevation between your antenna and the airport runway may complicate this formula. If your CB station is near an airport, you may contact the nearest FCC field office for a worksheet to help you figure the maximum allowable height for your antenna.

How do I set my sx700 radio to work with hands-free headsets? Any assistance would be appreciated.


Hands-Free Use With Accessories (VOX)
You can transmit hands-free with the use of optional accessories. Once
VOX is turned on, the radio detects your voice and transmits when you
speak.
1. Turn the radio off and plug the VOX accessory into the accessory
port.
2. Turn the radio on. VOX shows on the display.
3. Adjust the volume appropriately by rotating the volume knob . Lower the volume
before placing the accessory on your head or in your ear.
4. To turn off, simply remove accessory.
Note: There is a short delay between the time you start talking and
when the radio transmits. There is a short delay before the
transmission is completed.

Owners Manual: http://www.motorola.com/mdirect/manuals/SX700_userguide.pdf

You must be using a VOX capable accessory. Generally this is an accessory without an in-line PTT.
