The mods for the SD2200 so far are the are the reciever mods, we are working on some Filter mods to sharpen the response from deep targets. We are also testing mods in the Filter stages and looking at increasing the gain and working on a low frequency super deep mode. I will put up more info as it comes to hand, if you want to email me you can at vk3kcg at amsat.org at=@ If I put a real email on this site the spam bots would harvest my email and it would drive my spam filter into overload.
Well now for an update, The SD2200 both D and V2 mods have been carried out to a number of detectors and the results are most impressive. I have even developed more mods for this series to give multiple detection timings by changing the Eprom code.
