Yeh, that's what I though you meant. But it isn't more or less power, it's just the focussing of the energy.
Your big girls thing I don't agree with. It may have been the case, especially with CRT's. On the two radars I have owned (different makes) I've not been able to improve on the auto tuning and certainly not while bouncing in a rib. Range is changed as required during the journey.
but you get better results if you fine tune the controls your self abit like a photographer doing manual focus
You would probably also need to readjust each time you changed the range which would be impractical on a rib.
Brilliance is no longer adjustable using TFT's but backlighting is and it is also adjusted as required, eg. into sun, following sun, running into an overcast area, falling darkness etc.
