I had the DR-620T and liked how well that rig performed, except for the out of band intermod in heavy strong RF congested areas, like metros. From what I've seen from the newer DR-635T, it's the RX fix to that. Much tighter intermod rejection. Other than that, I didn't see the difference to the DR-620T. Good perky TX audio, and like pretty much most Alincos, maybe too much TX audio. Easy enough to adjust, but there's two POT's for that, DEV V for VHF and DEV U for UHF. (Just be sure that you have a deviation meter for this, or something else for audio measurements.) Good, perky, RX audio as well. One minus? On cold weather days below freezing, the UHF side drops its Squelch, until the rig warms up. Don't bother getting the Digital board, since it doesn't seem to be compatible with any format out there. Other than that, a nice alternative to Icom, Yaesu, and Kenwood.
