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

Radio not receiving on any channel


Hi Mike,

The manual for this radio (in Adobe .pdf format) is available for download directly from Icom America, free of charges.

Since the "AquaQuake" function works and you do hear static when the squelch is off, that is sufficient to let us know that the voice coil of the speaker is functional and should produce sounds with the right signal applied.

The first thing to determine is if you're close enough to another operating transmitter for the radio to receive a signal. One of the 10 weather channels the radio is capable of tuning should be close enough produce some intelligible audio from the speaker - assuming the squelch setting isn't set too high.

If a WX channel works, then you'll need to see if there's a VHF Marine band transmitter operating nearby. You might need to set another Marine band radio receiver up to verify that there is indeed a signal present on the particular Marine band channel that you're monitoring. A list of frequencies is published on pg 27 (of the manual linked above) in case you need to convert between channel and frequency to tune on a non-channelized radio.

Outside of that, there's little the end user can do without specialized test equipment, schematics and of course, training. Many shops will be happy to provide an estimate for repair when provided with a small bench diagnostic fee. This fee is usually applied towards an authorized repair by most reputable repair shops.

I hope this helps & good luck!

Display says OFF


You are on a portion of the 2 meter band that the radio does not allow you to transmit on. You need to get within the legal band portion and transmit there. The IC-V8000 only transmits between 144.000mHz and 148.000mHz. You likely have the radio outside of that range.

Is it possible to convert the cobra 29 wx nw st sound tracker cb to 10 meter amateur band?


No it cannot. If you want that buy a Ranger or a Galaxy.

The 29 can be altered to increase modulation and turned down in power to match it to amp for increased output of power.

Set to dead key a watt or so with a 100 watt amp it would dead key low and swing to 80 to 100 watts pep.(peak envelope power)

How do i get expanded freqs on my ft1802 yaesu tranceiver


The FT-1802 is a 50 watt 2 meter FM transceiver. It can transmit anywhere between 144 - 148 Mhz (the FM portion) of the 2 meter ham band. It can receive anywhere between 136 - 174 Mhz without any modifications. There is a modification to enable transmit "out of band" below:

http://www.ham.dmz.ro/yaesu/ft-1802-extended-transmit-modification.php

There are few details about the results of this mod - typically these provide for transmitting on frequencies outside (above, below or both) of the 2 meter ham band. Transmitting outside of the ham band without a proper license for the frequencies in the U.S. is a violation of FCC rules.

VHF transmit power


Hi, It is not typical but neither is there a problem with the radio. Transmit Power output is loosely dependent on the: 1. Frequency or channel you are transmitting. Normally, Marine Band VHF are calibrated for max (25 in your radio) at Ch16 or 156.800Mhz; 2. If the SWR of the antenna is not a flat 1.0, power tends to go down; 3. After some time, the TX side of the radio needs to be re-calibrated; 4. Power Supply - some radios will push max output only when powered with 13.8 and tends to go down when used with 12 volts. Hope this be of some help/idea. Post back should you need additional information. Good luck and kind regards.
