I just got a cw key in the mail. Went to give it a spin, plugged the key (Nye speed-x), turned the radio to cw, and was met with a constant tone. Followed the user manual which didn't have many steps to using the radio in CW mode, not sure what the problem is. Tried changing the radio to mox,vox,ptt, turning up and down the carrier, etc. I have the radio set to manual for the keyer, so that isn't the problem. Thanks in advance.
