This one has Option 7 installed, takes 10 MHz in and has 4 10 MHz outputs on rear. Front has selectable output (10 and 1 MHz, 100 and 10 KHz). I had to add another On-Off switch as the one in unit is not functional. Bench checked and works. I just got an SRS FS710 so I don't need two. $80 shipped to CONUS. 73, Dick, W1KSZ
