[INRAD] 400 hz filters

[Gus Samuelson]

Received the 2 X 400 hz cw filters and the 2  X  2.1 ssb filters   just in time to give them
a work out in the CQWW160 meter contest ...  have to say that the
switch from the 2 x 500 hz stock filters was very dramatic !!
But am not surprized ( or shouldn't  be )  as I had already used a pair of 400hz filters purchased
 20 years ago and installed in a 930 I had..
just needed to have my memory refreshed ..
Thanks for prompt shipment ...
