No TX Icom 706MkII on FM but ok on HF

i am using an Icom 706MkII, Signalink USB, and Omnirig. I have freq control on FM, but will not key up the radio transmit. I do see the Signalink PTT light up, I do have audio going out, it is just the radio will not transmit. Oddly enough, on HF, VARAC works fine. Tx and Rx work, and freq change via OmniRig CAT control works great. FLRig does not initialize at all, tried that. Only thing I need to have FM working is to get the radio to key up! Dean
