Indoor K band tests

Hi!

I so hot here today, so I made some indoor tests to see how M4 platform will perform with different settings.
I use two DIY K band emmitors ( one at 24,070 and the other at 24,220 Ghz)
After many QT and IO, strange thing is that in Autoscan mode, M4 escort passport 8500 x50 euro will react quicker than in Highway mode!
Bel 955 not shown any difference.
Also i discover that low voltage will slightly decrease reactivity and sensitivity (12,4V vs 14,4V).
I made another test with an M4 and an old Cobra tested side by side (both "on" in the same time). Both sensitivity and reactivity will not suffer on M4 escort when another leaky detector stands nearby (15cm apart).
