For some reason, life meant it good with me and let me obtain an article I long thought lost. An ICOM AT-120 :-))
The tuner suits my two marine radios, aka SSB radio telephones, IC-M700D and IC-M700TY perfectly. Could well be that the tuner will join one of the radios on board Pandia for /mm operations on 14.313MHz or PSKMAIL frequencies.
Most likely, the AT-120 will match Pandia's backstay, other configurations are thinkable however....
