I've pretty well decided to go with a script based mod to let the bin code take over part of the scan storage area of the flash--can't see an easy way to mod for compression of the area only using script.

Here is a sample script and 1M dump from a modded 217 bin with reduced scan area 0x60000 - 0x6ffff. Compressed bin start at 0x70000.

I scanned two DN sats and results were good, how it would do with other sats is a big question. I'm sure there will be problems with any channel name longer than 0xb bytes as I've only allocated 4 words total (0x10 bytes), but I've noticed that no channel names I've scanned are larger than 6 bytes. There are places in the code I think I can mod to force the name length to be limited, but haven't played with them yet (still leaves on trees, so my view of sky limited). jvvh
