Re: [Elecraft] Fw: Hardware Differences K3
I missed the news on a new DSP board also. I have K3 #101. Is this something I should be looking at? Buck k4ia In a message dated 12/16/2009 11:38:58 A.M.

Re: [Elecraft] Fw: Hardware Differences K3
We started shipping the current DSP boards, Rev C, approximately March 6th, 2009. Any K3 DSP board Rev C or later will have the extended low end audio frequency response h/w enhancement. This corresponds approximately to K3 serial number 2800, plus or minus 10-20. Since assembled -Fs and kit K3s flow through different manufacturing paths, there is a slight variance in s/n for the phase-in. If in doubt, check the DSP board Rev as noted above. These changes basically added additional h/w low end frequency response below 300 Hz. You need to also have the latest K3 f/w to take advantage of this. Of course, you can also tailor (and limit) your RX and TX response via the K3's IF Shift and B/W controls and by using the TX and RX Equalizer entries. A picture of the Rev label location on the DSP board and additional info is at: http://www.elecraft.com/K3/mods/dsp_rev_c_information.htm (The 'C', or later, revision letter at the bottom of the label is what is important.) We have added to our parts and mod kits page an option, K3DSPUPGD to swap out your current DSP for one upgraded to the latest Rev C changes. The cost will be $69.00 plus shipping. Order placed via this page will start shipping approximately in 4 weeks, around Nov 9.

Re: [Elecraft] Fw: Hardware Differences K3
Thanks for re-posting the info. I am just not sure how much of a difference this makes to those of us who aren't too concerned about hi-fi audio. If I'm listening to a CW note at 700hz, or normal SSB, can what's below 300hz really matter? Buck k4ia In a message dated 12/16/2009 3:56:48 P.M.

Re: [Elecraft] Fw: Hardware Differences K3
Hmmm, no mention of the (hardware) AF low pass filter in the announcement quoted below... can Elecraft confirm/deny? There is no documentation of the K3DSPUPGD option on the order page, and nothing in the K3 Alerts, Enhancements and Application Notes page either.

Re: [Elecraft] Fw: Hardware Differences K3
I'm wondering the same thing myself as I've held off on the upgrade. I couldn't really come up with any outstanding reasons to improve something I didn't believe needed improving. Anyway, I'm open to reasons. If someone can give me a good one, perhaps I'll swap the boards out. 73, James K2QI -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of k...@aol.com Sent: Wednesday, December 16, 2009 4:05 PM To: n...@carolina.rr.com; elecraft@mailman.qth.net Subject: Re: [Elecraft] Fw: Hardware Differences K3 Thanks for re-posting the info.

Re: [Elecraft] Fw: Hardware Differences K3
Jim, Replacing the DSP board isn't that difficult; remove the front panel, and you'll see the DSP board attached to the rear of the FP via a couple of stand-offs and some screws. If you take your time, it could be done in under 30 minutes. If you ordered your K3 assembled or have never taken the FP off before, download the assembly manual from the website and you can see the required steps beforehand. 73 de James K2QI -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jim Miller KG0KP Sent: Thursday, December 17, 2009 12:54 AM To: Steve Ellington; elecraft@mailman.qth.net Subject: Re: [Elecraft] Fw: Hardware Differences K3 Is this a mod that can be done in the field?

Re: [Elecraft] Fw: Hardware Differences K3
Sorry, I was talking about actually installing the individual replacement components on the original boards myself vs replacing the two boards and if that was possible. (OK, I'm cheap(retired), trying to see if I could get by for something less than $140). I think I would rather buy another filter or a W2 instead and live with what I have in DSPs now.
