Actually, i have the HDBK 161 and TM-487, although i have to admit, it's easier to use online, than to dig thru all that paper. Also, the receiver i was thinking of, kinda looks like the R-96, but it's a Wilcox airfield unit, single cabinet with transmitter in same cabinet, has some kind of FRC-nomenclature but i sure cannot find it. -Hue
