Thanks, John, for your part in this "recovery" and nice chronicling of the event. Yuri sounds as good as always with the new power supply. FWIW, my last VO-52 contact, on what we will likely refer to as "the old transponder," was with Yuri: 28.02.2012 0035 UT1FG/MM VO-52 M-B SSB EJ78 Yuri off coast of Costa Rica 73, Jerry, K5OE
