Howdy, 
 
As a result of spring garage cleaning I found one more box  that had an A5 
rev D ISB board and a pair of the matched USB/LSB crystal filters  8409/8410 
that should have a new home.
 
The board is untested, really, as in not known bad, as I pulled it a couple 
 years ago from a receiver missing the main board, the filters came from 
another  similarly situated orphan missing several other boards, and I had set 
them aside  for a rainy day project.  The filters seem to have the 
appropriate  bandwidth and passed signal when inserted into my test mule receiver 
but  haven't been checked thru byte or swept.  The 8409 pins wiggle a bit but  
not so much that they push back in the filter housing or short to the case 
as  near as I can tell when I put them in the mule, but should be stabilized.
 
I'll ask $200 Paypal for the lot AS IS plus shipping if anyone is  
interested before they head to E swamp, tell me I'm whack if the price seems  high 
and you really want them, and will consider any interesting trades if I get  
no cash takers (or if the trade is really good :) for some combination of  
decently used stuff  selected from the group consisting of a good  Fluke VOM, 
RF or scope probes, an SX122 working or parts radio as long as it has  the 
bandspread cap, 455 khz cw or am filters that can be made to work in an  
elderly HQ215, or 9 mhz cw/ am filters like the old McCoys as I'm building a  
vintage project, any R4C roofing filter or switch boards, or a 3 or 4 khz R4C 
 bandpass filter).  Or anything else that guys of our ilk might like, as  
long as it's something I can use and won't put back in a box in the  
garage......
 
 
Thanks, Scott ka9p
