My 1st dual band mobile rig. Full features you'd want and expect, until you went into harsh RF environments, like metro areas. Intermod on RX is terrible. The DR-635T is indeed the better RX improved version of this rig. Apparently, there is a modified fix for this. So, if you see this rig for $100.00, or less, grab it! One thing about all Alincos? Their audio is hot right out of the box. Simple adjustment internally. Look for a Phillips Headed POT marked DEV for Deviation. Just be sure that you have a deviation meter, or something else for your TX audio reference when doing this adjustment. Other-wise, nice audio quality for both TX and RX. Oh yes... For you cold climate ops, the 440MHz Squelch will drop on you while the rig is cold, but come back after it warms up. The DR-635T does that too, so it must be an Alinco thing.
