I would think a Flex 6300 R Model would be perfect for the SWLers that are interested in a Top line RX only receiver. Especially without the Ham Band band pass filters such as in the 6700R. Hmmmm... what a money making scheme... I could buy oodles of 6300 radios and throw away the TX side components, pencil in an 'R' after the 6300 Logo and make a fortune! I had a similar idea years ago when I found a gold nugget the size of a small house.... I broke it up into very small pieces and spread it out over the hillside out back... started a Gold Rush and then opened up a Hot Dog stand! Sorry... just thinking out loud before the next release.
