7 MHz/ 10 MHz well ....horses /courses
if there is a base 1000 km away 10 MHz will be far daytime superior.
Bases further away mean lower ionospheric angles which means the whole
path and frequency selection become less critical. Well there is much
more to it than that.
antenna efficiency on a car sort of goings according to wavelength
cubed... so 10 MHz is usually alot better... lower noise on 10 MHz...
I will run some GRAFIX charts
is there a list of 7 amd 10 MHz IGATES around the country?
You might be better off for example with a 20m IGATE in NZ in the daytime.
