[Elecraft] [K3] s/n 282, K3DSPLPF addon

[Nand Kishore]

I presume my K3 has a Rev.B DSP board.This is my 'only' radio.
I cannot disable K3 for any duration either for swap-out of dsp to
bring it to Rev.D status or go through the hassle of getting a current
dsp board with a lead time of whatever and shipping back removed
dsp board.

So,  can I install K3DSPLPF on Rev.B dsp board, I'm asking about
physical compatibility. Rather late to ask as I'm collecting my P3 kit
and  K3DSPLPF from the post office tomorrow.
