Re: hand-held radio

Set the radio for simplex ptt monitor out buttons turn on radio make sure the other radios work with each other hold the monitor down if you hear white noise then you dont have the simplex duplex setup right and or try holding the monitor button in when other people are transmitting that would indicate a ctcss programming problem

Re: hand-held radio

Hello Think you have to make sure that both radios have the correct encode and decode CTSS or DPL, if you dont select the encode for one of them the other one just will light the green led but will not recieve. Also make sure that the speaker is working correctly. Check your programming parameters one by one. Good luck

Will transmit but will not receive

I have programmed hundreds of these. The radio may be receiving, but the speaker may be muted. If using a hand mic, have the mic "off hook" or ungrounded and try again. Does the front light flash while the radio is receiving? This indicates the radio is "hearing", just not passing the audio to the speaker. Is there something plugged into the audio jack in the back? Let me know. In 20-30 minutes most shops familiar with Vertex will know exactly what is happening.

When I turn it on, why does it indicate confirm?

Something is wrong with the programming. It does not happen often, but it happens. Reprogram it, or find the factory reset in the manual. If that does not work, the radio memory chip is defective. Reset is your best option.

Motorola t6550 radio wont transmit but it will receive

Hi Robert,

I need more info regarding your radio to be able to assist you.

Is it a tiny Hand Held, or a proper sized HH?

Was it made in China or elsewhere, if China, then there is your culprit/problem.

Nothing made in China, radios that is, has been fixable, due to the bad, cheap and poorly way these are mass produced.

If made in another country, please reply with full details, and I will do what ever it takes to find a solution for you.

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.

I have a radio TK 701 H. The antenna is a homemade J with copper tubing. The power source is a Macromex transformer that has adjustable voltage. It transfers from 120 volts ac to variable volts dc,...

It's possible some of the repeaters you're hearing are using CTCSS tone squelch. The other people won't hear you unless you have the right tone selected. 15 V is too high for most radios. They're rated at 13.8, so turn you power supply down to something between 12 and 13.8.

Radio stuck in RX mode.

Your PTT button is possibly at fault. It may be partially depressed, leaving your receiver open. Behind your PTT button there is an internal PTT button on the componet board. It may be stuck or defective.
