Hi Chris;
I would stop using the radio immediately!
Sounds like the main audio chip U1 on the DSP board is going out.
When they fail, you can get a HI CUR warning because they are shorting out.
They can heat to the point of destroying the DSP board (which we don't
have anymore).

Hi I have a strange problem with my K3/100.
The audio through the internal speaker is low, but comes up
much stronger with any slight movement of the volume knob.
Then it goes back down again, often accompanied by a brief
HI-CUR warning.
Also when AGC is turned off, audio is almost zero.
But, wit
This weekend I suddenly began to have an oscillation problem in the speaker amp
of my K3 (SN 969)) Headphones and the RX both work fine. I don’t hear the
strange audio oscillation in the headphones), but the speaker amp appears to be
having problems. If I turn on the speaker using SPKR+PH YES I
Contact Elecraft service. I had a similar problem a couple of years
ago. The radio had to go to the factory for diagnosis. We ended up
with a board replacement.

When I key the transmitter on SSB I hear a 700 or 800 hz tone being sent
along with the audio. Unable to figure out what is causing this. Any ideas?

Garry,
I am not at home right. Using another radio's config file will probably
not work as the calibrations would be different between the two rigs.
If you can get them on the air or by email I would suggest doing the EEINIT
process and then redo the calibrations outlined in the manual (watt met

download the same configuration file as used by the other K3, and re-start it.

Just spoke to VK4FW at T2T. One of their K3's works on CW but has died
on SSB. Bill says they disconnected all cables, set all settings to
match another K3 that is working on SSB, checked the microphone routing
on the Main Menu and of course swapped out headsets. No joy. They are
frantic to get

John,
I believe that HRD and DM780 does not provide a path for audio, you must
use something like Skype in addition to hear the audio on the local

My DSP board failed 4 months after the kit K3 #818 was assembled.
I had no audio anywhere. The S meter showed almost full scale. The receiver
