Hi I am using an Icom 7300 with my MFJ 993B Intellituner with the MFJ interface cable. I notice today that the tuner would not tune up 10MHZ. I normally tune at 20 watts power. But then again if the antenna is already resonate for that frequency then I may not see anything happen I do not know. I normally tune anything from a 3.5 swr to 1.1 swr.?

Thanks

What is displayed for the SWR, forward, and reflected power on the tuner? What
does the power output of the radio and on the display show (you would have to
press the LCD Mode switch to get the other parameters to display)?

If SWR is close to 1:1, then there would be no need to tune. This would
especially be the case if you were using that band previously. If you're putting
out close to 100W, and SWR is low, then there's no need for the unit to go into
the tune mode.
