I have? radio number one that has only a ssb filter and it is strapped to the AM and CW position.
The problem with a ssb filter being used in CW is that strong stations near my operating frequency produce agc action and I have difficulty copying that weak cw station due to agc pumping. Thats why a cw filter is necessary. It? is very noticeable while there is a contest going on.
The radio number two has all 3 filters installed but the 250hz cw filter in the cw slot is to narrow. I like it but there are some guys that dont know how to zerobeat be so I dont hear them at all.?
I would never use a 250hz filter in AM mode, its to narrow.
The sotabeams filter works like a champ but you still suffer from agc action since it is hooked up to the earphone jack.
I have another FT301 arriving this week but it does not have the amplifier on the back
and the insides will be a mystery box with good or bad surprises.?
