[Elecraft] WTB: KFL3B-FM Crystal Filter for K3

[Russ]

Hi:


Does anyone have a KFL3B-FM 13 kHz FM  Filter that is excess to their needs?

I picked up a K144XV-K at a hamfest this last weekend..


Thanks,

Russ KD4JO

Hi:



I currently feed a powered speaker with the constant line output of my K3. I can individually adjust that speaker's volume locally and the HP volume on the K3.



I'm contemplating the purchase of an SP-3.  As this speaker is unpowered, I will have to use the K3 power amp and am afraid that I will lose the individual volume control versatility I have.



If this is the case - would it be possible to repurpose the sub-rx (I don't have one) AF gain "ring" to control the speaker amp level.  My understanding is that the speaker out and HP out's are fed by separate DAC's.



Thanks, Russ KD4JO
