Hello Ed
You mention a mod from LA3ZA in your post.
Seems I am too blind for finding it either on the Elecraft HP or on LA3ZA
mod list.
Would you be so kind please and provide me a link to that mod description ?
Thank you
73 de OE2CDM, Dieter

Subject: [Elecraft] KDSP2 LED Stays On and No Audio
My KDSP2 has operated very well over the past 2 years and four months since
I built
it... until last Saturday. I had removed it to work on the front
panel, installing indicator LEDs in the key caps as per the LA3ZA mod which
went very well. When I reassembled
the rig to test out the mods the KDSP2 was not functioning properly.
With the module removed and replaced with a unpcb bypass board, audio is
restored. I have made no changes to the DSP2 module and I do take the
precaution of working with my grounded static drain mat and wrist band.
The KDSP2 LED stays on instead of extinguishing after a few seconds which
indicates that communication is down. I verified that all connectors
and pins are aligned properly and the battery measures 6 V. With the KDSP2
installed, even though
the LED stays on, I am able to cycle through the filters using the
XFIL/AFIL Front Panel switch... but, no audio.
I seem to remember this problem coming up once but can't recall what to do
to cure
it... wish I had written it down when I had come across it before. It
seems that it is something simple that I am overlooking.
I appeal to your collective wisdom in solving this problem... Thanks,
Ed - AD7GR
