[TK880 displays "yyyyyyy"]

I got 2 of these from eBay that have the exact same issue. They both have the same modifications for some digital in-out port on the back.  I just set them aside for now.  If I ever figure out what has been modified on these, and get it returned to normal, I'll post details here.

 

Interesting. Mine does not have the digital in-out port on the back. I think that may be for Fleetsync. I am working figuring this out today, and then I will put it aside for a while. If I do get this fixed I will be happy to share the solution.

 

Regards,

I am glad that I am not the only one struggling with a TK-880! I purchased one from Ebay and I have not had any luck getting the KPG-49D software (ver. 4.20) to access the radio. When I turn it on it quickly displays VER: 1.5164 (Passport firmware?) then displays CH   1. I cannot get it into programming mode from the panel and the KPG-49D. I get an error message that says "Please check connection and communication port setting". The power switch, volume buttons and the monitor button work but nothing else. 

 

I have not found a way to do a hard reset or unlock the radio. It is a TK-880-1 Ver 2.0 according to the tag. Frustrating to say the least. Ham radios have been a piece of cake in comparison.
