K3 New DSP Replacing
Locked

I got my new DSP-C board. Somewhere I saw a step by step on how how to
replace it. Can someone locate it for me?

I think someone sent steps in an email recently, but you should be able to follow the steps in the KDVR3 installation manual, which involves removing and reinstalling the DSP board ... ~Iain / N6ML ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

You mean they don't send you instructions on replacing it?

G'day,
It's not exactly rocket science, you take the front panel assembly off, remove a board and replace it with the new one, replace the front panel assembly. The assembly manual covers the front panel work or maybe just download the DVR installation manual it's got all the information you need for taking off and replacing the front panel and more. However, having said that even the relatively trivial upgrade of the digital I/O interface came with the usual pages on how to take the top off but there was also some track cutting. The other day we had a request for an instruction to click on a button in the K3 utility that was clearly marked with its function. It seems these days that hands need firmly holding.

Mike:
I wasn't really worried about taking it apart. I was just surprised that Elecraft didn't include instructions given what comes with their kits and add ons. 73, John N1JM On Sat, Jan 9, 2010 at 5:57 AM, Mike Harris <[hidden email]> wrote: > G'day, > > It's not exactly rocket science, you take the front panel assembly off, > remove a board and replace it with the new one, replace the front panel > assembly. > > The assembly manual covers the front panel work or maybe just download the > DVR installation manual it's got all the information you need for taking off > and replacing the front panel and more.

No instructions included.
I've also been told that the production version of the Rev. D board doesn't have the little add-on LP board and that those components are now built in to the main DSP board. I have not verified this but it does make sense.

How can we ensure the LPF is there once we receive our rev D boards? That
little LPF is the only reason why I upgraded, and I'll be knackered if I get a DSP board that doesn't have one. Cheers!

> How can we ensure the LPF is there once we receive our rev D boards? Look for either: (a) a small piggyback board on the back of the DSP board near the speaker amplifier IC (U1, at the upper left corner of the PCB as you face it in normal orientation with the component side of the board facing you, or (b) an IC (U30) and a number of components surrounding it to the right of the speaker amplifier IC (U1). Note that Rev D refers to the "assembly level" of the DSP board, *not* the raw PCB revision level. If you are still uncertain, after you receive your new DSP board assembly, send me a private email with photos of both sides of the DSP board and I'll let you know if it is equipped with the LPF or not. 73, Lyle KK7P ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Hi John,
No, they don't. I used a suggestion made earlier on the reflector and looked at the instruction for adding a grounding wire to the front panel microphone jack. It is "Front_Panel_Microphone_Grounding.pdf" and can be found on the Elecraft web site in the page named "K3 Alerts, Enhancements and Application Notes." To do that mod, you have to remove the front panel and the DSP board, so it guided me. 73, Oliver Johns W6ODJ On 8 Jan 2010, at 9:24 PM, N1JM wrote: > > You mean they don't send you instructions on replacing it? > > John N1JM > > > > Steve Ellington wrote: >> >> I got my new DSP-C board.
