[Elecraft] Independent Headphone & Speaker Volume

[J.K. Hooper]

Russ, 

There is a input A and input B switch on the SP3.   I only use input A to the speaker, so when on headphones I push the A/B switch on the SP3 to mute the speaker.  

I have a Behringer MicroAmp HA400 4 channel stereo headphone amplifier I use for field day, when we might have multiple folks on headphones listening to the radio.   That could be used as a separate volume control for your headphones. 

73,

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
