[Dstar] DSTAR DX?

[Heath - VK3TWO]

I'm sure they also have different RF paths through the cavities...
Stating the obvious here, however can have some considerable effects.
Comparing 10W to 25W you are only looking at 3-4dB which is negligible when
you look at potential losses of cavities etc.

Even if you are using the same power but different radio, different radios
can de-calibrate cavities so you aren't comparing apples with apples after
all.

For comparisons, i would suggest using EXACTLY the same for DSTAR/FM. ie,
same Ant, Coax, Duplexer, Radio, power, however simply swapping mode from
digital to FM.

Perhaps a collaborated effort across 100's of Km and even 'remote
controlled' radios on mountain tops etc. A bit over the top just for
testing/DXing, but when one want's to play...... :-)
