FS: Elecraft/Inrad filters
|
Initially Elecraft produced the 5-poles. I still have one in my K3, the 200Hz.
Later on, 5-poles were replaced by 7-poles, just like the K3 was replaced by K3s

It is interesting to learn that there is 7 pole filters. I had only seen 5 and 8 pole filter before

I thought Elecraft roofing filters for the K3 were either 5-pole or 8-pole. And say why they "appear" to be matched? Thanks! 73, Paul K6PO

I have extra filters I ended up not using in my K3/S so they are for sale:
