Tytera TYT 9800D Plus - Failure to connect to repeaters

[kk6cqx]

Just purchased new. Tried to set up an initial test.

I am able to transmit simplex. But when I use a repeater, the audio is not transmitting. Basically seems that CTCSS is not transmitting at the start of my transmission.

I have set the frequency, offset, tone, and set it to ENC.

The radio does key up the repeater when I release PTT. It seems that the CTCSS tone only transmits when I release the PTT Key.

I can hear myself on the reverse frequency.

I have tried the following to troubleshoot

1. I have tried multiple repeaters.
2. I have tried manually inputting the settings as well as using the software
3. I have reset the radio to factory
4. I have tested with other radios
5. I can hear myself on the reverse frequency so I know audio is going out

Is there another menu setting I am missing? Everything on the radio is still set to factory settings.

Thank you

Do you have the correct tone frequencies? Do you have the TX tone turned on?

what program are you using to program the radio, or are you doing it by hand, it can be a learning curve?

 

[WA0CBW]

Hmmm.... If you hear the repeater when you unkey then the ctcss is working.

I have tried programming by hand and by software.
I’ve confirmed the tone frequencies for the repeaters I’m on. And I hear myself on the reverse frequency. Tone is correct because it is keying of the repeater. But only after I release the push to talk key.

 

[WA0CBW]

That would be normal operation. What your are hearing is the squelch tail. That is the time the repeater stays keyed after someone stops talking and the repeater transmitter stops transmitting. Some repeaters may have a courtesy tone during that time to let you know it is your turn to talk.
Is there something else you think you are missing?

The behavior on the radio is not normal. I know what you’re referring to. I have just learned through experimentation that it functions only on low power. If I try middle power, one or two or high power, then I cannot talk to any repeaters. It only transmits the tone with voice when using low power.

What are you using to monitor yourself on the repeater? If it's another radio and it's in close proximity to your transceiver, it'll easily get overloaded with RF and not hear the repeater output.
When you stop transmitting and the repeater goes into hang time, it can now hear it.

Move your monitoring radio MUCH farther away, or better yet, have someone at another location monitor the repeater.

TYT 9800D Plus is only transmitting the tone on low power. Mid1, Mid2, and High power do not work. Radio is defective.

OK, I'll bite. The radio may be defective but there are other things to check.

What make/model/amperage continuous-duty power supply are you using? If in your vehicle, are you wired to the battery with sufficiently heavy wire? The radio may misbehave if the voltage and amperage is too low.

Or...

Is the antenna SWR acceptable? Too high, and I've had radios kick in protection and fail to work as expected.

YMMV.

 

[kk6cqx]

I’m wired to a 30 amp 12v power supply. Tested with other radios and meter.

I used two antennas with acceptable swr readings on analyzer.

Or, it's because the lower power isn't overloading your other radio.

Again, what are you using to monitor the repeater when you are transmitting with the Tyt? Where is it located in relation to the transmitter?

Located in another room of the house with the help of my wife. Kenwood THD74.

Is the TYT radio a mobile install or using a base antenna?
As @mmckenna said, it really sound like you're overloading the "test" receiver. How about removing the Kenwood's antenna? That will significantly attenuate the amount of RF entering the radio. Another option is to send your wife down the block and have her relay info to you via cell phone.

AND, have your tried contacting someone else through the repeater and asking for a signal report?

I would have another ham try listening to the repeater and see if they hear you.

A 50 watt mobile transmitting on the repeater input frequency, in close proximity (even in the same house) to the Kenwood is likely overloading the receiver on the output frequency. It's likely overloading and desensitizing the receiver. When you stop transmitting with the Tyt, the Kenwood can hear the squelch tail.

As ladn said, you could try removing the antenna on the Kenwood and see if that helps.

Or, turn the Tyt down to it's lowest output power setting.

 

[kk6cqx]

I have tried multiple repeaters and asked for reports. Using another radio on the same repeaters I was able to make contact.

 

[mmckenna]

Might be CTCSS deviation is too low.

I'm not familiar with these radios, so not sure what options there are. Usually setting CTCSS deviation is something that is done through service software and requires a service monitor.
If you have a ham locally that has a service monitor, they should be able to check it for you.

Which brings up another question: Make sure you are not set to narrow deviation on the radio.

I did try changing bandwidth settings as well to see. I did a lot of experimenting to troubleshoot this thing. Given everything (explained above) I can't help but conclude the radio I purchased is defective. Thankfully purchased it on Amazon. So simple return. Now I'll be looking at a Yaesu (for double the price).

 

[WA0CBW]

Be patient with us. We are trying to make sure it is the radio and not something you are doing wrong. So to be sure we all understand the problem you are having could you again explain the problem again. Is it using the TYT you are unable to bring up the repeater and no one on the repeater hears you?

I'm not at the computer with the RT Systems software I use for my TYT, but going from memory, there's two per channel settings that influence the xmit audio: 1--Mic Gain and Deviation:

Make sure this is on WIDE for testing purposes. You can change it to MID later.

2--Compandering

Set this to ON.
