[1000mp] Inrad 1.8 installed

[Tõnno Vähk]

I installed both Inrad 1.8 KHz SSB filters into the slots of 250 Hz narrow CW filters. I wanted to compare their performance to the 2.0 KHz Yaesu filters that are in the rig.

I notice that there is a frequency shift when I use those 1.8 filters in SSB this way and I can tune back to the right frequency with the SHIFT knob. Is it normal?

Is it possible to use those 1.8 filters in the 250 Hz slot or it is meant for CW filters?

Can I use those Yaesu 250 Hz filters in the SUB VFO now? do they fit?

That shift aside I can confirm that the performance is really head and sholders over the Yaesu 2.0 ones in cutting off the splatters...
