I put in a 219 250 hz filter in the 9 mhz if slot. It replaced a 400 hz
Inrad filter. I find that it has quite a bit of attenuation (maybe 10db?).
But it does reduce the QRN a lot. This is on 80 & 160m.
Do others find this or maybe I have a bad filter. And yes I have the jumper
in the high gain position. And boy does it narrow up the passband.
I have not had time to see if this makes the difference in copying DX in the
noise or not.
I think that I tried a 221 filter and did not like it for some reason, I
dont remember. Different center frequency?
Any comments or suggestions?
Thanks
