Hi Jon, Thanks, I'm glad you liked it! I'm trying to control my feature creep tendencies, so I'm just going for an incoherent, non-Doppler radar right now. However, I plan on providing an RX IF output jack and TX IF input jack, so that it would be easier, later on, to add a coherent signal processor if I ever get around to it. The LO board I just designed should be very stable and fairly low phase noise, so I think it might be good enough as a basis for a coherent system. Essentially, I'm hoping for something that can map out moderate to heavy rain within a several tens of mile radius. My biggest limiting factors are a 20 Watt peak output power (only affordable amplifier I could find) and the 3 foot dish (need to fit it in my car).
