To answer your question, there are 10 ohm resistors in the phones line - one in each channel. So you are losing more than half the audio power in the resistors. (On the plus side, you'll still have an audio output working even if you accidentally short the audio to ground!)
If you are not using the 2M/4M module for VHF you might be able to install a miniature jack for an external speaker. If you do not use the internal speaker at all, you might just unplug it and connect direct to the speaker connector near the internal speaker. Acoustical filters like that work very well. That one looks quite short. I'm used to seeing a smaller diameter and longer pipe. I had one that was driven by a single headphone and produced plenty of volume for a room with my old rx, but that was back in vacuum tube days when receives typically pumped out a watt or more of audio. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of stan levandowski Sent: Monday, February 6, 2017 6:09 PM To: Walter Underwood Cc: [email protected] Subject: Re: [Elecraft] KX2 speaker/headphone question Nice speaker but unfortunately won't help me out here. I need mono output for this speaker and it's only 2 inches and 8 ohms. If I could get the volume from the headphone jack that I get from the KX2 speaker, I'd be quite satisfied.
