Hi Folks,
I am testing a K3 with a THP HL-2.5Kfx. Is anyone using this setup??
I think I have the pin outs correctly. I know there is a low output voltage on the K3. I don't know why the AMP does not like the K3. I have the AMP set for Yaesu. That is basically what the band data is for the K3/Yaesu. I would love some tips, tricks, help, and etc...

Here is what I know:
K3 DB15 = THP HL2.5
Ground 5/12 = 5
Data 0/A 13 = 3
Data 1/B 3 = 11
Data 2/C 9 = 4
Data 3/D 14 = 12

IF you can point me in the right direction, I would appreciate it.
