Re: [Elecraft] I need More RX Volume on my K3, has anyone run an external audio amp?

[Dave Heil]

My answer is to use the Radio Shack Optimus SA-155 Integrated Stereo 
Amplifier.  It was also produced as the RCA SA-155.  Specs are 1.8W per 
channel, 25-25,000 Hz.  Has tone and balance controls, an 1/8" stereo 
phone jack and a tuner, CD/tape and phono switch.  Works fine with phone 
or the beefy speakers I use (about three times the size of typical 
computer speakers).  Mine sits atop  the K3 with 3/4" to spare on either 
side of the K3.

I use this amp with my KX3. It runs off 12V and it is 15W per channel. $8.50 
from Amazon.

Re: [Elecraft] I need More RX Volume on my K3, has anyone run an external audio amp?

[Harry Yingst via Elecraft]

It's actually "AF Gain" and yes it's set to 'HI'.
I just need to find a good 10-15 watt RMS Stereo amp to put in line with the 
speakers.

When I'm trying to pull a weak signal out and switch on the NR the audio gets 
pretty light.

That combined with hearing that has taken some abuse (Military, industry etc) I 
just need a little more volume.

There's an AUD GAIN parameter in the CONFIG menu. If it is not already set to 
HI then try that first.

Thank You

The specs say that the SP3's are rated at 15 watts so I should be able to find 
a small stereo amp

Yes, I have an old SS 15 watt HIFI amp I use to feed a small HIFI speaker under 
the desk.  Works great and I can fill the room with CLEAN audio.
