That's the 2LF which converts 200KHz to 3.5MHz to the 10 meter bands and it
did plug into the calibrator socket.  Fairly hard to find but with the wide
AM filter in the 2B, not very usable for much more than beacon hunting on
LF and CW and SSB on 160.  That's the reason Drake didn't make many of
them.  One was on eBay recently.
