It will divide my Rubidium 10 MHz reference by 10 to get 1 MHz, and also divide a voltage controlled crystal oscillator at 24 MHz (or 25) to 1 MHz and then compare the two 1 MHz signals and use that to lock that crystal oscillator, making a Rubidium controlled 24 MHz (or 25). That in turn will be the reference frequency for my LNB, the 25 MHz (or 24) is then multiplied by For a 24 MHz xtal: LO1 = 24 * 390 = 9360 MHz LO2 = 24 * 426 = 10224 MHz to form the local oscillator for the LNB down converter to receive the Eshail2 ham satellite Eshail2: 10498.675 MHz horizontal Downlink: Narrow band 10489.55 to 10489.8 MHz center 10489.675 MHz Wide band 10491 to 10499 MHz center 10495 MHz resulting in a IF frequency of: IF LOW side 10489.55 - 9360 = 1129.55 MHz 1,129,550,000 in IF band RTL-SDR lock High side 10499 - 9360 = 1139 MHz 1,139,000,000 in IF band start narrow band 10489.55 - 9360 = 1,129,550,000 Hz center narrow band 10489.675 - 9360 = 1,129,675,000 Hz end narrow band 10489.8 - 9360 = 1,129,800,000 Hz start wideband 10491 - 9360 = 1,131,000,000 Hz center wideband 10495 - 9360 = 1,135,000,000 Hz end wide band 10499 - 9360 = 1,139,000,000 Hz that then will be fed for narrow band into an RTL-SDR stick, and for wideband into my PC satellite DTV card. Or something like that. Sat is not up there yet (I think, but spaceX already has it) so not in a hurry. When PLL to 25 MHz I can just use it to view regular sat TV, in the picture above the original 25 MHz is glued to the side of the LNB to test if the modification did not kill it. Very tricky to solder on that board, tracks just come off. So there will be an external 24 MHz or 25 MHz reference input to that LNB, 2 cables to it. At least that is the planning.
