Hi all, I spent some time last night pouring over the ECO's and determining which ones were done to my radio. I did end up taking off the BPF board to get a better look at the RFE. Also during this process I reviewed the block diagrams that Peter sent (thanks!).
Today with the help of Joe (AB1DO) I was able to test my radio against his radio. When we hooked up the XG1 my radio was showing the XG1's signal at about S3. It was also quite a bit off frequency and suffered from some serious image issues. After a few runs at calibrating it and tweaking it back on frequency we ran it against Joe's SDR. The result were that the calibrating (with a good signal source) seems to help significantly. My radio still seems to be about 10 dBm down from his but I believe it to be because his radio has the newer preamp (ECO025). We listened to a signal that was showing around -90 dBm on my radio vs. his which was showing about -80 dBm. I guess the lesson learned is that if you own a SDR-1000 you best get a XG1 or similar signal source. Maybe future Flex Radio models can incorporate a similar circuit? Unfortunately, I had to go back to work but I'm looking forward to getting it hooked back up in the shack tonight. Thank everyone who responded with suggestions and comments. And a big thanks to Joe for making time today to help me sort out the problems. It's great to have a local fellow Flexer!
