Locked Re: My Icom 718 overheats quickly and drops power #Windows10 #signalink

One further point along this response - You are going to want to use your antenna tuner/coupler to keep the rigs SWR as low as possible. I suspect the 40W limitation at 100% Duty Cycle accounts for a good match. Any high SWR (i.e. 2:1:1) would exacerbate the heating problem, and consequently lower the power at which you can hope to achieve 100% duty cycle.

The SWR stays about the same.  I believe I have been over power and have dropped with good results.
