Lonestar: An issue or setup changes needed?

Post by OZ1HMN » Sun Dec 20, 2020 8:05 pm

Hi
I have a RPi3B+ with a Chinese Jumbospot and Nextion 2.4 (USB) display. Working fairly well.
Just received a Lonestar simplex board. Replaced the Combo with the Lonestar, and set RX/TX offset to 0 (as on the box).
The setup receives the data from wifi and displays it correctly, but I have no signal on my radio, and no reaction in the display when I key my radio.
If it swap my Jumbo in again, everything works fine.

Do I need to do some setup changes, or is there a potential issue with this board?
Have rebooted, update/upgrade but still doesn't work.

Sounds like there is an issue with the radio portion of the board, since you say that it communicates correctly and displays data on the OLED.

Maybe the offset shouldn't be 0.

You could try to run MMDVMCal and see if you can get the board to respond to keyups, you can also use MMDVMCal to transmit a tone from the board, and maybe use an SDR to find out if it is transmitting.

You are not by chance in the satellite portion of the bands are you?
145800000 through 146000000 on VHF
435000000 through 438000000 on UHF

If thats the case then your old hat is running older firmware and the newer hat is running newer firmware where that is activated to prevent interference.

Thanks. No I'm in the 433 range.
Tried the CAL procedure, but no signal at all. Tried with another DMR radio, but same result.
So module must be defect I guess.

What do the logs report?

And does the dashboard show that theres network activity?

Everything indicates that it is working. Only thing that is not working is RF rx/tx.

Have been debugging it with the board developer (which is very helpful).
Have x-tested with two radios, a RPi3 and RPiZ, and Jumbo mmdvm board.
Might have died during transportation.

Well, it could only be a few things:

the ADF7021
the traces between the STM32 and the ADF7021 (only 3 should have any components (1k resistors on pins 34, 35, and 36 on the ADF7021) the rest are direct (pins 24, 25, 26, 27, and 28 on the ADF7021)
the traces between the ADF7021 and the antenna (which may or may not contain a bunch of various components, I always forget what its technical name is)
the antenna connector
the antenna

and the biggest culprit could be the TCX0, check and make sure that thing is putting out 14.7456 Mhz into pin 39 on the ADF7021
