So.... I just purchased a TT4 and accessory cables.? After installing drivers, I connected the TT USB cable to my computer (Windows 10). Looking at the Device Manager for the COM port, I get the

The yellow CD LED was not flashing and I wasn't seeing decoded packets. I just reset the TT4 to base configuration and it's working again, so #shrug? Thanks for the response. Issue seems to be fixed

When you say it "Stopped detecting carriers" do you mean that the yellow CD LED is not flashing, or that you are not seeing decoded packets?? 73, Allen AF6OF

Super fun getting into APRS. I had a TT4 set up for about 2 weeks with a Kenwood TM-231A successfully operating as a digipeater. About two weeks ago I started using APRX as the digipeater and iGate,

Thank you for the research and fix! Looking forward to moving forward with my project.

What kind of a USB-to-Serial cable do you have, a Byonics programming cable or a standard USB-to-serial cable? The Byonics cable will power the MT-8000FA during programming to avoid problems with the

That's a curious statement since you just joined the Group this morning. Yes it's monitored and yes, it's active. I'm sure you will have some member provided input quickly. And, please, always sign

I'm not sure if anyone still monitors this group but I have a Tiny Trak that is not being recognized by the software.? I have isolated every usb port I have and labeled them accordingly.? This is

Brian, I received your MTT4BT today. It appears that the corruption of the TT4 ATMEGA controller stemmed from the 2.5mm PORTA jack getting a bit bent and having intermittent contact. The programming

It may be due to loss of precision in the arithmetic used by Byon and not round off. It could be both. Without seeing the code employed in converting temp input to ascii for embedding in the aprs
