DSP Board Upgrade

Hi All, I just received my K3DSPUPGD board. My K3 (#3223) is a Factory built
unit. Therefore I have no experience at dismantaling and re-assembing the
radio. I have an Anti-Static Mat and Wristband and the Elecraft instructions
seem to be very clear. I did follow the recent thread about grounding/ESD
protection and keeping everything at the same potential while handling the
PCB's.

My question, is there anything in particular that I should be aware of doing
this change out that may not be as clear as it needs to be for a beginner?

TIA, 73 Earl N5ZM

Re: DSP Board Upgrade

The upgrade is pretty simple. The hardest part is mating the front
panel back up with all the pins. Apparently I managed to bend a pin
under a connector which was causing my odd headphone jack readings and
other noisy issues with the radio. Take your time and go slow.

Re: DSP Board Upgrade

Hint: Prop mirrors so you can see the ends of both 0.1" DIP
connectors off to the R and L sides of the K3. Some little 2" compact
mirrors work for this, so ask your XYL for used compacts if anyone
still actually uses them.

You can see both connectors, then you'll at least get the outside end
pins seated, a good starting advantage.

Many thanks to Dave, Harry, Mike MU, Mike MK, Mark and Matt for the
information.

Everyone agrees that I should pay very close attention when re-mounting the
Front Panel.

Also to clean the pins before re-assembly. I have had no problem with bad
connections but will be sure to dress them up before putting it all back
together.

Again many thanks to all,

Earl N5ZM..

Earl,

Did the same here.
It's an easy job, if you take it step by step. Don't be in a hurry.
