My K3's speaker audio seems to have gone West. Audio out of the phones, but nothing out of the internal speaker.
It happened when I was installing a new external speaker, a DSP Desktop speaker from BHI. Having read some recent posts about the audio chip blowing up because of using a mono plug instead of a stereo one, I made sure that I used a the correct one. Following guidance in the K3 users manual I connected the speaker to the LH channel as I want to use my headset in stereo. I also took the covers off and checked for the modification involving 470ohm resistors. That mod was in place OK. I switched the K3 and the speaker on and got audio from the speaker. However, when I advanced the AF gain on the K3 to about 12 o'clock there was a pop and no more speaker audio from the K3. I have checked the BHI speaker with another rig and it works fine, so my K3 has developed a fault. I can't believe how sensitive it is to damage in the audio output, particularly with the care I took to try and avoid this sort of thing happening.... As I am quite OK with SMD's I would appreciate advice on what to change, where to get it and how... Not a happy bunny ! 73 Stewart G3RXQ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
