Hello... I'm new to the group.  My Rpi3B+ has been running an IC-7300 for nearly a year, but suddenly no HDMI output.  At boot, the green led was still blinking, but no HDMI. After fiddling around

Depends how old it is. Early versions of the firmware didn't have the txdelay pot reset feature. 73, John G8BPQ On 06/12/2020 22:43, Tadd KA2DEW in NC via groups.io

so we know that both LEDs are hooked to the CPU and that the CPU can light them. The question then is why doesn’t it blink the correct pattern when the CPU is booted with the TXDELAY pot rotated to

or the tower of Babel if you prefer LOL boots and runs off a Samsung 860 EVO 500GB SSD drive

yep, along with a Nexus dual controller/TNC hat, Pi-FE audio card etc. I call the stack Godzilla LOL No issues

They blink only once. Tim

When the TNC is rebooted or powered up the start sequence blinks the lights. Mark KD0QYN

Yes there are many and no issues. Mark KD0QYN

Does anyone have the TNC Pi 9600 running on a a RPi 4? Any issues or??? thanks Mike KE7TJK

Hi John N0JDS. It's almost a year since your post, but I wanted you to know that your thread here saved the day. I had just about given up! I've configured a Raspberry Pi 4 B and 400 for WSJT-X, and

Yes both LEDs blink when you add power. I assume the processor see power and blinks the LEDs Tim

Update on this. Was using the separate RPI for rig control on 40M and started getting the freeze ups again. Turned off rig control and it works fine. So back to work figuring out the issue.

The tip on adjusting alsamixer did the trick on the 3B+, 4B and even the zero, HOWEVER, the received text via the Signalink USB is garbled on the zero w. I cannot imagine the zero shouldn't work with

Oh, also fail2ban and ufw to enhance security. -- John D. Hays Kingston, WA K7VE

I am running Raspberry Pi 3 Model B Plus Rev 1.3 as a server on my LAN to provide several utilitarian services: AMBEserver Asterisk + FreePBX (including MySQL + Apache2 + NodeJS) OpenVPN Client (to

If I remember correctly, the yellow DCD light will light up if the incoming audio stream randomly decodes to a valid HDLC header. This can and will happen but it won't last for long and the LED

All of TNC pi do that.

Thanks Alan. I did not know that. Now to keep the two versions straight. I'm still going to give it a try. BruceN / K4TQL

Check the location of the flat on the red led. It should be facing the non nectar, not the edge of the board. Mine was backward, and I had to unsolder it, turn it around, and resolver it to the board.

It's normal for the Yellow LED to blink from time to time. This means nothing, actually. Mark KD0QYN On Friday, December 4, 2020, 6:39:15 PM
