This radio requires a set of headphones with a sensitivity of 105db or higher. Most low cost headphones only Sat, 23 Mar 2013 21:26:07 GMT GeorgeG http://groups.yahoo.com/group/FtTuthill80/message/1204 http://groups.yahoo.com/group/FtTuthill80/message/1204 I have made several contacts with this rig.

Zero issues and the build manual is excellent with testing steps as you go and very clear pictures and deluxe layout Sat, 16 Mar 2013 00:28:57 GMT Barney http://groups.yahoo.com/group/FtTuthill80/message/1200 http://groups.yahoo.com/group/FtTuthill80/message/1200 Hi Wayne; I have one in my 'to do' box along with about 10 or so others.
