[SCCC] phones and external speaker

[Dick Kalkofen]

Keep it simple.....

Find a Stereo Splitter and connect it to the EXT speaker jack and plug the Speaker in one side and the Cans in the other.

I don't know if it's handled differently on your MarkV, but the way these
normally work is that audio is fed to the headphones and speakers
simultaneously, with the headphone jack being an NS type (normally
shorted). Inserting the headphone plug physically breaks the NS
connection, thus cutting audio to the speaker. Check your schematic first,
but potentially all you'd need to do is jumper across the NS connection so
that it is *always* shorted. But of course, that might create late-night
operating issues with the family.  ;^)

Maybe a better way of doing this (that doesn't involve going inside the
radio) would be to wire a dongle from your headphone plug (or homebrew a
series "box") with a speaker jack and switch... and maybe a resistor
network to get the impedance correct for the speaker.

I have a MarkV.
I plugin my headphones to the front "Phones"
I have an external SP-8 speaker that plugs in to "Ext speaker" on the back

I'd like to have the ability to send audio to both sources at the same
time (headphones ON, Ext Speakers ON).

Why? My son comes in the shack, and I'm working DX on CW - I'd like for
him to hear the pileup while i keep the cans on.
