[NLRS] Question regarding modes/frequencies

[KA0RXX]

Hello all-

This is my first note to the group, so I hope it's an appropriate 
topic.  My son (KD0ABR, 11yrs), I and a couple of others are interested 
in playing around with PSK on 2 meters.   When doing a web search for 
where that might be appropriate, I am coming up with 144.144-144.150 Mhz.

Since I am pretty new to anything other than FM on VHF, I was hoping 
that you folks could either confirm that this would be an ok frequency 
to work this mode on, or point me in the right direction?

Thanks so much for any guidance and putting up with my ignorance.
