The quickest is to key a multiple pole relay with the exciter output, and wire each of the relay poles to a separate device. The annoyance is the relay will not be perfectly quiet. You would probably

There should be plenty of power to the speaker jack for an external speaker. I've come to prefer the Motrac vintage Motorola metal cased speaker, but some prefer the later plastic cased Motorola spea

The Motorola speaker also has quite high efficiency and gets a good listening level with less audio power. Could be that the different speakers and different headphones require quite different power

Unfortunately the audio envelope isn't the RF envelope and severely clipped audio results in peakier RF than unprocessed audio. Gives it a splatter characteristic, so saith the book on SSB by Collins

If that's a problem, the device needs better roll off control, but you can get RF bypassing and HF roll off with a small resistor, say 8 or 10 ohms in series with the bypassing capacitor. -- 73, Jerr
