I have a 979 and i have the freq. counter which just plugs in the back of the radio. When i turn it on its off freq. slightly but once it warms up like Grogan said its good to go. I do live in Ca. so mild weather compared to some. When my 2980 needed some work I brought it into the house, i had never checked the SSB output and it was low I adjusted it up some myself, it wasn't even to 12 watts. After that I made a lot of contacts with great reports. I wouldn't be scared to buy another, that being said i would lean towards the Optima.
