I have just got a new in the box a TET model HB433DX There are no instructions for it. The date on the box is 1998. I found a reference on a Japan site saying it covers 7/14/21/28 and is 3el. Anyone have anything on this beam?? Charles F. Frost Frosty K5LBU frosty1 at pdq.net http://www.africandxsafari.com
