I wonder if the perceived clock problem is the same as in the IC-7100. Namely if you do not use the rig for many months the clock battery will discharge so when you turn it on it will have to be reset and left powered up for 24 hours. The clock drain is only a few microamps so I would expect the clock to be fine until at least a month after the internal battery goes flat. That should be avoided therefore the clock should be a non-issue.
I’ve not found the IC 7300 more susceptible to overload than say the IC 7100. 32 bits is a big dynamic range.
The sensitivity looks adequate on paper. I have used an RS918 on several activations and found it on a par with the FT817 re overload and sensitivity. The IC 705 looks better on paper than the RS918 which does need some extra operator involvement with the RF gain when operating on the same summit as another SOTA station.
Yes, the omission of an internal ATU is an irritation. However you can buy an auto ATU kit from oriental suppliers for a fair price.
We might see the IC 705 in stock by the end of the week.
Oh and I expect the touch screen to be a resistive one like the IC 7100 so it should be fine in Scotland etc.
