Your SD card is probably bad. Try another. If that doesn't work, then perhaps you have a bad Pi. Try another, they are cheap. This is rare, but I have seen it happen. Let us know how it works out. Mar

Good old time research data. Thanks for posting. Also, people today tend to forget that most communications now is serial. The SATA drive on your computer, serial, your WiFi connection, serial, USB 3.

Carlos, I'm glad you figured out you local network issue. These things can be very frustrating. There was an issue a couple years ago with the script that checks if the PiGate is connected to the Inte

There are lots of USB to Serial dongles on the market that will work well. The device can show up with various device names, such as /dev/ttyUSB0 or something else, but just using that as the serial p

David, Thanks for the comments. As I mentioned, the OS boot loader is fine for Pi4 boards I bought prior to Dec 1. Now it is not, so yes, the version of Raspbian is probably too old for these new boar

David, There is nothing on the terminal. The LED blinks are the clue of what is going on, it can't start the boot loader. The newer Pi4 boards probably have a new boot loader name hard coded into the

Well, as I mentioned in my message, the same image worked on all Raspberry Pi boards from the Pi Zero up to and including the Pi4 (2GB) until last month (Dec) when two new boards will no longer boot,

The question, as noted on the subject line, was PiGate and ARDOP. Since I developed the PiGate, I should know the capabilities. Yes, John Wiseman has developed a "C" version, ARDOP_C, which also runs

Like I said, there are other people getting the same file, so I don't know what else to say. I just tried and it was received. I was a little misleading in my last email though. The update file is onl

Not the FTP server. There are lots of other downloads that are going on and they succeed. I can't tell what your IP address is, but there is one that keeps failing after downloading only a portion of

Carlos, The log file will tell you what happened. Perhaps you can post all of it for a better understanding. Mark KD0QYN

Carlos, Which PiGate device are you talking about? The "regular" PiGate or the PiGate RMS? They both use a similar means to notify you of an update which requires an Internet connection. What exactly

Many application have an internal default for the minimal screen size. The 800x480 resolution of the display is probably just too small. You might try looking for a small 10 inch or so HDMI monitor th

The PiGate and PiGate RMS do not officially support ARDOP. Someone is working on ARDOP software for Linux, but it is not yet available. I'm not sure if it will ever be available since Winlink is almos

Allen, There are other methods for talking to other hams, sending email, uploading and downloading files via ham radio, etc. One that has been around for awhile is pskmail. I don't think there is any

Jay, What you are experiencing are the problems with open sourced software. If you use the Debian package system to load software, it *usually* is easier and more reliable than compiling the software

Yeah sometimes things just fail for no reason. It's not hard to have a backup on hand for $35. Same for the SD card. Cheap insurance. Mark KD0QYN

Yeah, if the HDMI monitor is not powered on when you power up the Raspi Pi, it won't display anything, unless you force it has noted below by someone else. Mark KD0QYN

Your SD card is bad. You'll have to make a new one. Use a class 10 card for years of service. Mark KD0QYN

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