Yes I heard that freq was reserved but didnt really know why,its very interesting!!!
Couldnt they use ANY freq to search for life though??
Note this comment from the linked article:

And we decided for engineering reasons that we could only build a really big one if we had a frequency round about 600 megahertz. Otherwise, the perfection of the reflector, if we went to a shorter wavelength, was not something that you could [do] by the acre, at least not at that time, which was the late 1950s. And so we picked upon this 610 megahertz band as the observing frequency.
There was nothing special from an astronomical perspective about the choice of the 610 MHz band -- and in fact, most SETI surveys have focused on the "Water Hole" between 1420MHz and 1720 MHz because it's a quiet zone that minimizes background interference -- something other civilizations in the galaxy would presumably be aware of:

Hydrogen atoms emit at 1420 MHz (a wavelength of 21 cm). Hydroxyl molecules, composed of one atom of hydrogen and one atom of oxygen (OH), emit at four specific radio frequencies ranging from 1612 MHz to 1720 MHz. When a hydrogen atom combines with a hydroxyl molecule it forms a molecule of water, the most essential molecule for life as we know it. Thus, the range of frequencies from 1420 to 1720 MHz is called the Water Hole. It has been a popular frequency range for many SETI programs.
And they search across many frequencies within the range. So despite what the article says, the choice of 610 MHz had nothing to do with the search for extraterrestrial life.
From everything Ive ever read on ' alien communication', Ive never seen anyone suggest they vocalize speech like we do...supposedly they use some form of mental telepathy or something like it.
Trying to detect them thru radio is likely a waste of time.
It makes far more sense to communicate via mental telepathy. We humans need to learn that way. How ridiculous is it to have a limited method of communication in that ANY limit to speed, however fast, is still a limit. In the scheme of things, radio waves traveling at the speed of light is probably just not fast enough when you have vast distances out there in the galaxy. Once you get out towards Mars communications still take minutes to get one-way. Someone could be dead in that time.

I think mental telepathy will be augmented by something like what Musk is working on. Capture what is going on in one person's brain and send that to someone else.
Also as far as alien life goes. If there is or will be spaceships from other civilizations I would think it would be unlikely to be occupied by actual beings from elsewhere. With the vastness of space and distance needed to travel here AI controlled craft would make more sense. Even for us going to Mars we don't send humans right away. And if that is the case they would communicate differently than if actual beings were there.
The CE5 (Steven Greer's crowd) protocol involves beaming mind messages to aliens and they claim that the craft respond.
There is no reason to believe ET has not got a better method of travel across the Universe than old rockets and slower than light travel. I suspect they are traveling a lot faster than light - in which case any idea that they will take years or even weeks to travel vast distances is a really limited one. If dimensional travel is possible for them then they just need to hop into another dimension and hop back out again.
