I guess another option could be to take your old board out of the radio
and send it to Elecraft for a factory update and wait for it's return.
Of course this would render the radio inoperable for that period of time
but at least you would know that your serial number vintage DSP board

I would gladly fit this daughter board and perhaps do the LF enhancement,
but several on this list seem to be saying that the exchange DSP board does
something more than these mods provide.
Can anyone clarify?

Good grief guys. Look at the shipping status on these. Due to the high rate
of orders for this item, and the slow rate of return of the exchange DSPs, new
K3DSPUPGD orders take 2-4 weeks to ship.
it would appear that Elecraft is reworking returned boards to D level. That
seems perfectly
This is exactly what we are doing for the DSP upgrade. They are fully
tested and have a full warranty too.

My issue is that I've already added a LPF daughter card and I've already
done a modification for low frequency extension. However Eric has
mentioned that there are further enhancements beyond just these two
things in one of his emails. Eric said in a previous email There are a
number of changes
Thanks for the explanation Eric. Now, maybe we can end this thread. 73,

Hi Brett - I apologize for any confusion on this issue.
The changes on the K3DSP Upgrade are just for low freq RX -and- TX
response and the LPF above 4 kHz. You are probably covered.
My main concern was that some had done only RX -or- TX mods on their
own. Some only have modified the RX path,

Somewhere either on this list or the elecraft site or ?? I read that
the boards were shipping up to 4 to 6 weeks late because of the
slow return of the old ones for rework.
So yes it appears
wanting one quickly.

I don't understand that logic. See Eric's post from 9:08 PM EST today.
What is wrong with getting a fully updated DSP board with a full

Have a look at the mod. Other than trying to make Elecraft justify each
additional nickel, it's really whether you want to upgrade the DSP board or
not.
You do the stuff yourself, you're responsible for what happens, or doesn't.
