Re: [time-nuts] rf generator/attenuator
I already thought of this. There are two missing components: 1. An ALC output amplifier to get a high, regulated output level. Did you encounter anything like this on EBay? 2. A shielded box for the ADF435X. Rick On 12/15/2018 11:43 AM, djl wrote: See: sv1...@40gmail.com modules to do what you wanted. With a nice oled and arduino, ADF4351=20 35-4400 MHz PLL external or internal 10 MHz reference and a controllable attenuator. Greek modules, not Chinese. Total cost seems to be about $80 or so. I also found modules like these on EBAY for around $25 each from the old country. hurry before the tariffs start! I think serviceable signal source, GPSDO locked, can be built from modules for under $100 Considering my first Polarad microwave generator at about 60 pounds and able to heat the shack, it's a bargain. Time spent looking, about 15 minutes.
