Searching archives...

How can I do this? I don't really want to search through each month's separately to find "K2 low audio" which is what I'm looking for.

(Well, while I'm here, K2 s/n 6905 has just been aligned using Don Wilhelm's instructions and is working ok, but the audio is only just loud enough. I have the volume up full when using a range of low/medium impedance phones or the speaker. Is this normal? I know the LM380 won't fill the room, but should give comfortable headphone listening...)

Thanks and regards,

Ian, G4JQT

Go through the Elecraft page, "Email list (reflector)" link in the
blue box on the main page. Pick one of the Nabble searchable lists,
one that lists by thread. 73, Guy.

I can't speak for others, but my K2 behaves the same, Ian. More audio output
would be nice.

Re: Searching archives...

This seems quite anomalous...my K2 (and my K3) will blow one out of the
room at half-setting or lower on the AF gain control...implying that
something is quite amiss specifically with the two K2's in question.

Here's a cute little $9.99 (shipped from Hong Kong) audio amp
that I use with my K3's:
http://cgi.ebay.com/Mini-Hi-Fi-Stereo-Audio-Amplifier-Car-Motorcycle-/290506078266?pt=LH_DefaultDomain_0&hash=item43a382f83a

If you have trouble with that URL, it's ebay item number
290506078266. I bought the unit from that seller, but it is
available from others.

The audio out is pretty clean if you turn down the bass & treble
controls. I connect one K3 line output to the left channel, and
the other K3 to the right channel. I've only had it for only a
few days now, and haven't run high power on any band other than
160, but it is immune to RF on that band at least. 160 is
usually a troublesome band for RFI. The case is aluminum. On the
K3's set line out = phones. With this external amp, and
protective Schottky diodes across the output, I'm hoping to
expand the K3's overall usable dynamic range with agc off. I'll
give it a workout in the 160 Stew Perry contest tonight. The
rainbow flashing lights behind the volume control are goofy, but
you get used to it.

There is another audio amp on ebay that wasn't there a few weeks
ago:
http://cgi.ebay.com/AV608-Audio-Stereo-Amplifier-Amp-Mp3-Mp4-Ipod-Car-/260708878380?pt=Car_Amplifiers&hash=item3cb375c82c

It claims to have higher power out, and comes with a DC cable. I
probably would have bought that one if it had been available. I
have not tested it, but it looks interesting.

Ian,

I would tend to believe that you have a problem in the receive path.
Turn to the Troubleshooting Appendix in the manual and find the section
dealing with Receive Signal Tracing and go through those steps to
discover which is the failing stage.

If you need further help, just ask here - but tell us which options you
have installed.

Well John make it 3.

My $8 solution was a powered Motorola speaker from a hamfest. As shown
on Tom's, N0SS, here:

http://www.n0ss.net/index_general.html

I did change 2 resistors in the feedback loop to set the gain where I
wanted it.

I would check the voltage in the AF chain and amp and look at the output
waveform with a scope. Fix it rather than bandage it.

Re: Searching archives... now K2 audio output levels

In reply to this post by Bob-270

Bob,

I agree that is the way to get more audio from the speaker - but the
original poster said he had low audio in the headphones as well, so I
suspect he has another problem, or very inefficient headphones.
