TK880 displays "yyyyyyy"

Question

Hey everyone,

 

So, I recently picked up a Kenwood TK880. I've heard quite a few good things about these radios, however when I powered it up for the first time, it displayed Ver: 1.5209, beeped, then showed yyyyyyy

From research, I learned this is likely a firmware issue in that it should be Ver2.xxxx as per the sticker, but was flashed to Ver 1.5xxx for passport use. Does anyone know how to obtain the FPro software and Ver2 firmware?

Did you ever figure out the problem? Bought the same radio/cable/software and loaded the firmware now it won't connect  thought it was the cable ordered another (FTDI ) 

Start with steps outlined in Service Manual (http://www.repeater-builder.com/kenwood/pdfs/tk-880h-svc-man.pdf), Page 16. Basically, make sure that your COM port number is correct and KPG-49D and radio operate on the same serial port speed. The default should be 57600.

Read the posts from WRAK968 in this thread to determine if you need to reflash the firmware.

Remember, that firmware for v 1.0 and 2.0 are NOT interchangeable.

And why do people keep buying these radios?!?

How can I make my Anytone AT-779UV show "yyyyyyy" 🤣

Because generally speaking they work quite well.  I have 4 or 5 between the 880 and 8180 and have had an issue with only one.   Well, not counting the one I fried after tearing the antenna off my SxS. 🤣

May have jumped the gun? When i go the radio it wouldn't go into program mode it had a program password.  I uploaded a new dat file for the gmrs channels it loaded fine then allowed me to enter program mode. uploaded firmware, because of message some items wouldn't work.. at first thought i might have loaded wrong firmware KT-880-1 V2.0 but I'm pretty sure at this point I loaded the right firmware..  the radio comes on displays channel 1  in program mode displays 57600 baud rate firmware sum= OADE. 

NOW front panel buttons do nothing but beep? figured i messed something up in data file. Made a few changes the one I question is front panel programing?  Anyway now the radio will not reconnect to programing cable says check connections and comport. that all shows fine. checked drivers comports everything i know ordered FTDI cable and same message check connections and comport.. will not connect ?

What about the label on the back of your radio? Does it say "Ver 2.0" like here:

If not, you have unversioned, or what is called "Ver 1.0" radio. The latest firmware for Ver 2.0 is E613, that's what I run in my radios. The latest for Ver 1.0 is E4B3. I have both firmwares (although I only have 2.0 radios). If you PM me with your email, I can send them to you.

So, if I read you posts correctly, you can upload firmware with FPro when turn on the radio with the SCN down, correct? If yes, your cable and port are fine.

Yep TK-880-1  V2 same as above.. used  FPro to upload. SCN down then power to enter program mode  and using Ftdi cable.. I have booth versions of firmware sum=  OADE..  At this point I think the radio has issues does not make sense.. The firm ware I installed is (V 208-OADE)
