Re: Dual Hat / FT-5DR / FTM-400XDR issue

Here is update. I noticed something odd. It looks like radio will start working with pistar “after some time”. Not sure if it is the radio or pi-star but after some worm up time it will start transmitting. I was at my ham friend other day and he also has 5DR. His works every time. We switched to par...

Re: Dual Hat / FT-5DR / FTM-400XDR issue

So I updated my MMDVM board with the latest dual hat firmware and also the entire system (rpi-rw, sudo apt update, sudo apt upgrade, rpi-ro) Now, after pi-star reboot, I did check that my TX and RX offsets are set to zero. Looks like my 400XDR is working very well now :) No firmware or configuration...

Re: Dual Hat / FT-5DR / FTM-400XDR issue

rPI W2 / USB micro to serial login?

I was wondering if it is possible to reconfigure the USB micro port (not the power USB micro) so I could use it as USB to serial when connected to my laptop. I usually have it powered from my laptop and would like to get a login screen instead or ssh to the device. Is this possible? Has anyone done ...

Re: Dual Hat / FT-5DR / FTM-400XDR issue

Yaesu does not support their products working with 3rd party devices like hotspots, so there probably isn't any hats that will work. There have been a number of people that have posted that certain Yaesu radios (mostly the newer ones released over the last year or so) don't work properly. Yaesu pro...

Re: Dual Hat / FT-5DR / FTM-400XDR issue

Tx for the suggestions. I will look into it and give some time for more detailed observation. I will post my finding here. As far as contacting the HAT vendor. Well, I did with one of them. I was told the FT-5RD is not supported (after a few weeks of trying). I will do further tests you suggested. I...

Re: Dual Hat / FT-5DR / FTM-400XDR issue

Here is the other two boards I got from Amazon “ MMDVM Duplex Hotspot Module Dual Hat with 0.96 OLED Display V1.47 Support P25 DMR YSF NXDN DMR Slot 1 + Slot 2 for Raspberry pi” with and Without OLED. I can only activate pistar with ftm-400XDR. 5DR can hear but can not activate when PTT pressed. I d...

Re: Dual Hat / FT-5DR / FTM-400XDR issue

Thank you for your answers. As far as your answer related to lowest power mode? That is what I initially started with. But no matter what I do and change (freq, offsets etc) I could not get it to get lower then BER 2.5-3%. I could never understand my own transmissions (parrot). I am sitting 2 feet f...

Re: Dual Hat / FT-5DR / FTM-400XDR issue

What was the exact command you typed? And when you use "sudo pistar-findmodem" what does it report? ~$ sudo pistar-findmodem Detected MMDVM_HS Port: /dev/ttyAMA0 (GPIO) Baud: 115200 Protocol: V1 Modem Data: MMDVM_HS_Dual_Hat-v1.5.2 20201108 14.7456MHz dual ADF7021 FW by CA6JAU GitID #89da...
