730 prgramming issues.

[ohgary]

I have a tk-730 with a remote full 160channel head. I am trying to program the sql button but no matter what button I assign to the sql button when you press it the back lighting goes out. I dont even see where backlight off is an option to assign to any key at all. Any idea why its happening?

You need a newer firmware IC.

All 3 radio's that I have are 1991 code, The eeproms do have a 4 letter code before them. Is that part of the "revision" code? Any idea how to
decode them, I have FAA eproms that have jpwg ( this is the one I am using now with the issues). jdta and jemj. My dual head eeproms are jpyg and jpzg. The eeprom on partstore.com shows a JPWJ

I was actually using the jdta version in the 730, but when i moved the jpwg version over I got my sql working.
The 830 got the older code and works well with the 32 channel head.
