It finally dawned on me today that the menu screen of a Connect Systems CS750 looks exactly the same as that on a Motorola XPR6550. In fact, there are even some similarities when it comes to operations of the two radios. Did, Covalue (the manufacturer of the CS750) basically knock-off the XPR6550? I have to admit for the price of a CS750, it's a great radio that performs well. It may not be a Motorola or the newest, fanciest DMR radio but it's been rock solid for me.
