[ICOM] FL52A problem-additional details

[John Geiger]

Here are some additional details about the problem I am having with the FL52A filter in my Icom 756.  There seems to be a large amount of insertion loss on receive.  When I put the filter in line I can hear only the loudest signals on the band, and only at max volume.  However, the filter is doing something, because I do get a little more signal that just the blowby from the FL100.  I took out the FL52A, told the software that it was still there, and put the "nonexistant" filter in line.  Didn't hear anything.  So, the filter is passing some signal, but just with a large insertion loss.  

Is this consistent with some of the pins not making contact, or does it sound like the filter is damaged?  Never had this problem with a filter before.
