No, it wouldn't.
The article gets it wrong. Hezbollah wasn't intercepting channel hopping freqs, decrypting, and then translating from Hebrew to Arabic in real time.
They were doing something far simpler: they were DF'ing the Israelis.
Direction Finding radio transmission techniques have been around for a century. That's right; a century.
You transmit, two different enemy recievers then triangulate your position. Now they know where you were when you made your last broadcast.
If you think about it in civilian radar detector terms, two antennas on a single radar detector will let you know the direction and range of the police radar gun's last transmission (e.g. Valentine 1 units)...with a little computer processing.
With the right software you can have a realtime map of your enemy's movements (well, for each transmission made, at least).
It doesn't matter if your signal is encrypted (for DF purposes). That would just mean that you don't see the mph figure on the police radar, by analogy. And it doesn't matter if your signal is spread spectrum (i.e. channel hopping). Why? Because you are still broadcasting radio energy from your same antenna.
What Israel failed to do in their offensive was to spoof their own Spread Spectrum, encrypted tank transmissions (e.g. with a couple of UAV's in areas away from the actual tank assaults). Simple spoofing would spread out Hezbollah's anti-tank defenses into areas where Israeli tanks were not venturing.
That being said, contrary to the nonsense in the news, Israel did quite well on the battlefield, anyway. Hezbollah is not itching for a repeat of the pounding that they received. Nor is Hamas.
