A while back I posted a request for info on this box. Nothing was forthcoming, so I thought I would ask again. This box has one input (10 MHz) and three outputs (72.5 MHz, 725 MHz and 7.975 GHz). >From my experimenting with it, it looks like I can lock the three outputs to a 10 MHz signal from my GPSDO. The three power leads are +DC, -DC and what seems to be an open Collector for a Lock Signal. I would really like more info on this item. Schematics would be great, but any info at all would be appreciated. Tnx, Dick, W1KSZ
