Open my local repter w. r


I think you are asking to use the local repeaters to extend your range. To do this, you need the local tone codes. Ham repeaters are not "public", so local clubs or even individuals own them. They restrict use and will give you their codes with proof of a valid FCC License. A License is fairly easy to obtain, but you must have one.

FT-90R Pl 136.5 does not open repeaters. Other radio detects the tone. Other PLs work.


check to see that your radio is set to encode or send the 136.5 tone and that it is not set to decode. Most ham repeaters do not transmit the tone so if your radio is set to decode 136.5 and the repeater is not transmitting the tone it will mute and you wont hear anything.

FRS 2Way Radio 14 Channel Conair Expedition MODEL FRS200SLV MANUAL


Here is some information that might help.
Range can vary due to topographical and atmospheric conditions. Voice transmissions on some channels are not permitted by law.
Use in DUPLEX mode, Repeater stations can re-transmit your signal over a wider area giving you extended range depending on the location, height and availability of the local repeater station.

For information on the locations of repeater sites in your area visit the manufactures website or look-up UHF channels and frequencies for your area.
Note: some channels / Frequency's are to be Avoided.
UHF Repeater operation is used when long distance communication is required, unless specifically needed use of the repeater channels is to be avoided. Some channels and emergency channels, some are calling channels for establishing communication and some are customary road vehicle channels.
You will need to look these channels up for your Area.

Other stuff on this subject on safety and safe operation.
Electromagnetic Interference/Compatibility
Nearly every electronic device is susceptible to electromagnetic interference (EMI). To avoid the possibility of electromagnetic interference and/or compatibility conflicts, turn off your radio in any location where posted notices instruct you to do so such as healthcaer facilities.

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.

Hello i have a yaesu ft-2900 it receives just fine but when i transmit it shows error. this radio is brandnew


Hi Gerald,

When you say you used the software to download frequencies, do you mean as in from the internet, or did you have to input frequencies via the software on your PC?

There is a difference, that's the reason I ask.

If, by using the software you manually input the frequencies, then did you input both the output and input frequencies or just output for each channel?

If the latter is true, and you are trying to access another user via a repeater, then that is the error.

Repeaters generally, require both the input frequency = the frequency you transmit on, and the output = the frequency you receive on.

Without both frequency pair, you won't be getting out, and no won can hear you, as you are basically transmitting as a simplex station on a repeater allocatted channel, hence the error message on your display.

The radio you have is used by many amateurs & CB operators, and both group utilise repeaters within their allocated spectrum, excluding 27 meg CB, which is simplex only, but with SSB included.

I hope this answers your query.

Best regards,
Peter

Looking to build a two way radio system.


You will have to have a vehiclular repeater that is in another band than the mobile so if your portable hand held radios are on UHF then I would advise a VHF high band repeater set up.
It will have to be a cross band setup meaning it will recieve UHF and transmit on VHF and also the opposite direction.
It will have to be programmed with CTCSS or PL of some kind to avoid interference and don't forget it will need to be FCC licensed for those frequencies if it is in the Business band.
Some mobile radios can be wired up through a mini controller and run that way if it is compatible.

Interference using maxon pm100 2 way radio


Hello susannebrown. There is a problem with the base station or repeater station. If your mobiles can communicate ok, you have problem with the base, check the antenna & coax connections. #2 Swap out a mobile with the base & test operation. If you can do this & found the culprate care it to the repair shop(less cost). #3 Swap has no effect or you can't, you have a repeater problem. Sorry, call a repair shop.

Configuring audiovox GMRS1072CH walkie talkie


With the issue of 240V if the charger has not a Voltage switch, you will need to find another charger/transformer with the same Voltage/Amps ouput that works with 240V.

For Vox operations, this feature works independly form channel, you should choose the channel# and code # first, to match both radios, and get them communicate, then the Vox feature.
In Some radios the VOX feature works with an external audio accesory, in other radios works with out it.
Basically if this radios works without it, you should see that the radio transmist by itself when you speak direct to the radio, and stops transmiting 1 or2 seconds after you stop talking.

Good Luck.
