[R-390] Mechanical Filters

[Scott Bauer]

 About Curry Filters.

 Buyer Beware is all I can say.

 I bought 3 and had Rick Mish install them in my EAC IF module, serial 
10,XXX.
Rick could not get them to work properly. 6 peaks. Curry told me that he 
does
not do customer support and the filters should be returned to whom they 
were
bought from. I finally managed to get him to look at the IF module. It 
turns out
he was installing defective crystals. He very politely told me that he 
would install
a set of his personal filters in my IF. I did not notice any difference. 
Very weak distorted
signals. It was awful and I am very disappointed. I believe I paid a 
total of $600
for the 3 filters, 500hz, 3kc, 6kc installation and alignment. I have 
other IF modules
that perform much better with the 40 year old stock filters. The IF is 
sitting on my
shelf for use as a spare.

Though Curry was polite and informative, the product is downright poor.
