[ICOM] Wanted: Narrower (than stock) SSB filter for IC-735

[D C *Mac* Macdonald]

I went to Inrad's page for IC-746 filters. In slightly
modified words from Clement Moore's "Night Before
Christmas" what to my wondering eyes should appear but
a virtually identical list of filters for the 746 that
are on the 735 applicability list.
 
Now I'm wondering if Icom OEM filters for the 746 just
might be applicable to the 735!

* * * * * * * * * * *
* 73 - Mac, K2GKK/5 *
* (Since 30 Nov 53) *
* Oklahoma City, OK *
* USAF, Ret (61-81) *
