Digital tone not bringing up repeater

Without knowing the model of radio or the specific repeater you are trying to access, the only things I can suggest are 1) check to make sure your radio is setup for duplex operation, 2) check to make sure the offset is correct for the repeater, 3) make sure you are in tone mode (not tone squelch mode) and that the tone is correct for the repeater, 4) if the repeater is still not coming up, listen for a while to see if others can access it. If you don't hear other traffic on the repeater there is a possibility that it is down.

Other information that would help get you an answer would be the make / model of the radio (you said Vertex but that could also mean Yaesu), and information on the repeater you are accessing (frequency, location, repeater callsign).

My motorola radius GP 300 suddenly stoped working, disconnected from programmed network, how can i connect back and sees it working back?

GP300 radios will operate either radio-to-radio or in conjunction with a repeater. If your radio no longer works through a repeater, you might check to see if it will work in talk-around mode (radio-to-radio). Check with your repeater service provider to see if the repeater is in working order. One other item which might occur with a repeater would be if your radio is no longer recognized by serial number by the repeater. This is also something the service provider could help you with.
Best regards.

How do I program a yaesu ft-270?

I will be working from the online version of the manual located here. It may or may not be the same as your printed manual included with the radio - so you might want to download this copy.

First, let's set the radio to automatically set up repeater input shift based on the published receive frequency. By default, the 270R will transmit 600Hz up or down as determined by the band plan. This feature is called ARS and can be disabled if desired. If it does not display a frequency 600Hz up or down from the receive frequency while transmitting, is has been disabled. Let's re-enable it by performing steps #1 thru #5 on page 19 of the manual. Once completed, the 270R will automatically shift the transmit frequency (to match the repeater input frequency) as shown in the top half of the "ARS-Repeater Subbands" graphic at the bottom of page 19. The bottom half shows the export version of the shifts and does not apply to USA versions. If you have "odd splits" (repeaters that have input frequencies that are non-standard ie: other than 600Hz; or shift up instead of down and vise-versa) you'll need to manually change these later as described in VHO Split Mode on page 21. Any repeater operating on 147.000Mhz may have a shift either UP or DOWN. As you can see in the graphic, 147.000 is between the (-) and (+) shift so it could be either direction. Double check to make sure the radio matches the shift that the particular 147.000Mhz repeater you wish to access requires.

Next, create a list of repeaters that you wish to save in memory (you can check online databases to obtain the most recent information). This list should include Name, Receive Frequency, any non-standard direction or value Shift (called "odd splits), Tone Type and Tone. The name should be 6 or less alpha-numerics in length and be something that helps you identify it . This could be the name of the repeater owner: "TIM, PETE, etc. ", the name of the club that runs it: "BARC, CMARA, etc.", the city or town it is in: "BOSTON, OAKLND, etc,". You might run into names that would create duplicates when there are more than 1 repeaters there in the same location. Boston has several 2M repeaters - naming them BOSTN1, BOSTN2, etc. may help you remember them, but it will be easier still to append the decimal portion of the frequency to remember - such as in the case of a Boston repeater on say, 146.030Mhz and one on 145.150. BOS030 and BOS150 would probably be easier than trying to remember which is BOSTN1 and which is BOSTN2. Placing the names in the 270R memory is the last thing done, so don't worry too much about a name for the 270R's display just yet.

Most repeaters use CTCSS for access. Some newer repeaters use DCS. Some require or even prefer that no tone be sent at all. CTCSS is an analog frequency and a DCS code is digital data. The repeater may require one or the other to be present to "wake up" and begin retransmitting your message. All you really need to know about these two systems is the you need to match both the tone type and the tone value to successfully activate the repeater. Set the radio to your desired default power output level. Tap the VFO button once to enter VFO mode (if not already in VFO mode).

Enter the repeater's receive frequency by twisting of the tuning dial (page 13) or by direct entry (page 14) via the keypad. When using the keypad, do not enter the leading "1" of the frequency - as all the frequencies that this radio can tune begin with "1" and can not be changed. With the repeater frequency displayed, next enter the CTCSS tone for the repeater as described on page 23. If the repeater uses DCS, follow the directions that begin 1/3 of the way down on page 24 instead. As far as "TONE" and "TONE SQ" are concerned, the difference can best be described in that a radio working on a repeater system benefits from use of TONE, and a radio working on in simplex operation (no repeaters) benefits from the use of TONE SQ. Since we're programming repeater frequencies, there's no need to select TONE SQ. If the repeater strips the tone from its output, your radio will remain silent if set for TONE SQ. TONE is a much better match for our needs. Remember, you must use the DIAL to select the CTCSS tone frequency or DCS Code. Unlike the repeater receive frequency, it is not possible to directly enter the tone frequency or code via the keypad.

At this point, the radio should be displaying the recieve repeater frequency. Since automatic repeater offset is enabled - the 600Hz offset frequency and direction are set. The tone type and value for this repeater frequency have just been set in the previous paragraphs as well. Now it is time to write all this information to the radio's memory. This is detailed 1/3 of the way down on page 29 under "Memory Storage". Once you have performed step 5 in Memory Storage for this first repeater, it says to repeat this same process. This means setting the next repeater's recieve frequency, tone type and tone value - just as you have done with the first.

Once you have made sure that you have unique names assigned and the other information above, you are ready to begin adding them into the 270R's memory. You can go back add names to be displayed instead of the frequency of the repeaters if desired. Page 31 details the procedure to assign an alpha numeric name to each memory location. Make sure that you are assigning the correct alpha-numeric to the repeater by checking the frequency from time to time - don't blindly add alpha-numerics to memory channels.

This is a very tedious process. Ham Radio Outlet offers Windows programming software and transfer cable by Yaesu called "ADMS-270" for $38.95. This package allows you to easily create many lists of memories on your Windows PC & keyboard that can be uploaded and downloaded "on the fly" I highly recommend this software - or any software that allows you to program the radio from a computer rather than the radio itself.

I hope this was helpful.

Repeater channels

Are you certain you are near a GMRS repeater in your area? If you have your radios set for the GMRS repeater channels the radios will not talk to one another unless you are in close proximity of a GMRS repeater. To talk radio-to-radio you would need to set your radio to one of the simplex frequencies available in the radio.

If you know you are close to a GMRS repeater, you might double check the Tx and Rx frequencies of the repeater to be certain they match the settings in your radio. Also, you will need to be certain your interference code is set to zero (the off position) to be used with the repeater. I didn't read up on the T7200, but if it has a Qt filter, set it to zero also.

Radios dont recieve from each other..

The buttons you are referring to are programmable buttons, and it would depend on how they are programmed. In most cases depressing the buttons will not change the radio in such a way you could not communicate. When changes are made, they are changed back to normal by shutting the radio off and turning it back on. See page four of the owners manual.

You might want to read the section on the light on the radio on page 3. It may help.

Here is a copy of the owners manual:

Other questions which come to mind: Have you changed antennas recently? Have you tried the radios together on all channels? Have you tried the radios in a different area? Have the radios been reprogrammed recently? Do you use a repeater? If so, the repeater may be not working or malfunctioning, or you are out of range, check with your service provider.

Alinco dj-v5 HT deviation adjust

To adjust the deviation of this radio, you don't have to take it apart. If you take the battery pack off, there is a sticker on the back of the radio saying Alinco. Pull that sticker off and underneath are the variable resistors. See the service manual for more details on how to make other adjustments.

First, make sure you note the present position of this pot so you can turn it back if you have to.

If you don't have any equipment to measure deviation, make a contact on the repeater and try turning the pot in small increments and ask the person to help you set the deviation so your voice sounds good through the repeater.

Once set, if the repeater has a touch tone test, go through and make sure all your tones are being properly decoded.

Please let me know if I can be of further assistance to you.

Good luck!
