[TenTec] Insertion loss

[jim-g4ppg]

Recently I acquired a 500 Hz cw filter from a friend who was parting
with corsair 2 to a fone operator
 I fitted this filter to my  Corsair as per the instruction in the
manual, the results have been disappointing
 I find that when I switch in the 500hz filter  an S9 signal will drop
to as low as S1 any help in resolving 
This  problem would be most welcome .
 
Thanks 73 Jim G4PPG
