The only one that I've ever used is the little logic board that goes in place of the DR7. It's handy for testing or tinkering with the stuff that's UNDER the DR7, including the PTO. Found a cracked solder connection in the PTO in a buddy's TR-7 that way, the only way I could find it was testing 'live' with the DR7 out of the way and the cover off the PTO. 73, -Jim -- Ham Radio NU0C Lincoln, Nebraska, U.S.S.A.
