In reply to Post # 325:
To better understand this, we have to look at the electromagnetic wave spectrum where 72MHz
band is in the broadcasting region and the 2.4GHz band is in the microwave region.
WHEN FREQUENCY INCREASES, WAVELENGTH DECREASES. Therefore, the 2.4GHz wavelength
is shorter and closer to visible light on the electromagnetic wave spectrum. Since visible light is also
an electromagnetic wave, 2.4GHz wavelength behaves MORE like visible light and travels in straight lines
until it is reflected, deflected, diffracted or absorbed.

What does the above have to do with the efficacy of SS for R/C in the 2.4 GHz band as compared to narrowband operation in the 72 MHz band?
You insist on arguing for the superiority of comms in the available (by regulatory process) lower frequency bands, while ignoring the contribution of SS in a higher frequency band to overall robustness of the control link. It has previously been stated (by me and others, without contradiction by anyone else) that S/N is a more indicative measure of effectiveness for a secure link than is raw signal strength alone as a performance measure. I concede as anyone else with a modicum of experience working in the RFarena that signal propagation is a lesser issue in lower bands of the EMspectrum. How does that affect the net result in comms security re a comparison of narrowband comms in a low band to comms augmented by SStechnology in a higher frequency band?
