Don't use very much and I think this was the first time I've turned it on this year. The "Scanner" says ON, but neither the TX or STDBY options are available on the C80. I am guessing maybe the connector between the C80 and the radome could stand cleaning or one of these units are dying?

It takes the unit a while to warm up before the options show up. How long have you waited?
Did it work before? My C80 and radar goes into Standby on its own after I start it up but it takes a couple of minutes before the Tx option is available. I am using the normal Raymarine cord that provides power and data to/from the Radome though. My radome is the smaller unit. 12 mile I think.
 
This may be unrelated, but I found the C80 with DSM, RADAR, heading sensor, etc. was very sensitive to battery condition. A slower than normal radar startup may be the result of impaired batteries.

Good point. I have noticed a similar thing. I upgraded the gauge of the power feed to my C80 to reduce voltage drop. The P.O. that installed it used light gauge wire, which was fine until I added radar, then it was not. Upgrading to 12 gauge wire to feed the c80 fixed the issue.
