[Elecraft] KFL1-4H ?

[Curt]

I completed a K1-4 about ten months ago, for 40,30,20,&15.  Lately am 
missing 17, and sometimes 10 would be handy.  This will become more evident 
as we climb out of sunspot minimum.  Found a note from 2006 from a Japanese 
ham who converted a K-1 filter to 10 meters.  Wayne had responded, 
mentioning the possibility of a future KFL1-4H option ("H" for "high 
bands"): a version of the 4-band K1 module that covers some combination of 
10, 12, 15, 17, and 20 meters.   Wondering if there is further news on this, 
or whether anyone has reconfigured a filter for say 20, 17, 15, and 10?

I would sure buy one if it became available.
