Tk3312 will not recieve repeater but audio is fine and channels with out pl are fine

1- Did you choose the right Tone for both RX & TX?

If you have RF present but not the right tone, the green led should turn on.
One of the side key should be a Momentary "Squelch Off" (By default, it programs like that). Use it when you you see the green led turn on.

If you have the wrong Tone Squelch programmed, the side key will let you hear the repeater to confirm the problem.

2- If it didnt do the trick, Look for a RX/TX frequency mismatch. maybe your RX/TX frequencies are wrong for this channel?

3- If you have checked all the above, maybe your radio have a bad ceramic filter and your unit has lost it's sensibility. (Youll hear only people near to you.)
If it's the case, usualy only one half of the filter goes bad. Try swapping the Bandwith type in programmation. If WIDE, try NARROW or the opposite. If you receive in narrow but not in wide, the filter is bad. In more than 50 radios with Sensitivity problem, I only got one with both Wide/Narrow sides of filter bad.
If you have access to a spectrum analyser, on a "RX Test" you should see ~0.2uV. Anything higher than 0.3uV mean you have a serious RX problem.

How do you get the RX icon to turn off? The unit just has a contant fuzzy buzz.

RX represents "receive" This indication will be present whenever the speaker is producing audio. The "buzz" you're talking about is probably static, and is technically audio from the speaker. To silence the "buzz" adjust the squelch just until the speaker falls silent. The RX indication should be off at this point.

It is important to note that the squelch is designed to keep the speaker silent until a signal is detected. You adjust the squelch based on the level of static at a particular time and at a particular location. The static level may change depending on those variables. If you adjust the squelch well beyond the point that the speaker is silenced, you may not be able to hear transmissions or calls to you unless the caller's transmitter is physically close to you. This is why the squelch should be adjusted only until the static is stopped and the speaker is silenced.

I hope this helps and good luck!

President Harry 2 classic does not listen (receive)

Hi and welcome to FixYa,

Initial tests:
  • if there is likewise no TX modulation, check / replace audio IC4 TDA1905;
  • if RX signal strength (S meter reading) is low, check RX + 8VDC;
  • try using an external speaker in case of a faulty internal speaker;
  • exercise the AM/FM switch.
If all of the above checks good, then signal tracing from the front end down to the audio amp. Would the schematics help?


Good luck and thank you for asking FixYa.

Tone squelch

Here is a link to download the user manual for the GP68

On your first radio, the one we've been discussing, I believe you have the DPL code set incorrectly. Your radio will go up to the number 126, but this is not the DPL code's number. It is simply a numbering system.

If I read the chart correctly:
DPL 205 equals the number 072.
DPL 023 equals the number 043.

Disclaimer: This numbering system listed in the user guide does not follow any common numbering system. I have other TPL/DPL charts which differ. The above reference is only based on what I have read in the user guide.

I am confident if your radio worked previously at another job site, using other frequencies/PL codes, that your only issue at this time is programming.

As for your unlock issue on the other GP68. Your radio may be in need of repair. The internal button is possibly wornout or has been depressed too far, and is bent on the board beyond the point of functioning.

Problem Recieving

First try programming the Receiver for Carrier only Squelch,,ie no PL /TPL, then check if it will receive the repeater OK.
If the audio still cuts in and out then (assuming no fault exist) either you mis-programmed the Frequency slightly, or the TPL choice was incorrect.

There is also a possibility of a Bandwidth mis-programming.

Repeaters may have 12.5 KHz or 25KHz channel bandwidth. Basically if you set your radio to 12.5 KHZ and it receives a transmission from a 25Khz Repeater because of the higher repeater TX Deviation the audio on your radios RX will cut in and out and may sound distorted and very loud as well. Your radios TX would sound OK though, but would have lower audio level when heard on the repeater RX. Does your TX work OK through the TPL repeater?

The RX symbol and static noise would only appear if the squelch is down or if you are receiving something from a transmitter.

Receiving something could mean either an intelligent radio transmission from another comparable unit or this could also be spillover signals from adjacent radio transmitters strong enough to override the squelch settings normally called "splatter". At times, electronic devices could cause this effect such as RFI (radio frequency interference) from units such as a personal computer.

It is also possible that your Monitor Mode is "ON", turning it OFF would possibly resolve the issue To turn OFF monitor mode:Press the vol/mon UP or DOWN key. The RX icon will stop blinking and disappears.

In some cases, a component failure would cause this problem. Your GMR1035-2 uses an Automatic Squelch Feature, this would mean the use of a FM Discriminator Chip for Squelch Control. Most manufacturers uses an MC3357P IC chip for this purpose. This of course would require opening the unit, desoldering the suspected component and solder in a replacement. This would further require that you be familiar with electronic components, circuitry, DVM and a low wattage soldering iron. Should you not be comfortable doing this, perhaps your best bet would be to seek the services of a qualified technician.

Hope this be of some help/idea. Post back how things turned up or should you need additional information.

Good luck and kind regards.

Constant Rx

Hi, It would initially seem that your auto squelch is malfunctioning. With the squelch apparently way down, the RX indicator would automatically appear as if you are receiving something (even if it were just noise). Assuming no other fault except the auto squelch, a possible workaround is to use any of the 38 CTCSS codes both in receive and transmit. With the CTSS activated (TX/RX), even with squelch all the way down or auto off/defective, you will not hear anything except a radio transmission with the correct CTSS code. Again, this will only work of course with just the auto squelch muting problem. Any other problem/fault and this method may not work. Hope this be of some help/idea. Post back how things turn out or should you need further information. Good luck and kind regards.

Motorola FV500 2 way radio can send/cant receive

Do you hear the Beeps on the speaker? Check for the QT and the code squelch are the same in both radios, try to set code squelch in "0". Make sure that the radio is not receiving or the other one is not transmiting, with two radios will see the same.
