Just FYI, I have previously mentioned only 1-way CAT communication with WRL and my FT710. Today after about 5 attempts to get 2-way communication in CAT CC with the FT-710 I decided to try the FT-891 setting just for the heck of it. I got two-way CAT communication with my710 immediately using the 891 option in WRL CC’s rig list .! I will experiment a bit more .
