Hi all,
OK, I think I have all the upgrade modes working on my K2 #402. It was
a lot more work than I thought it would be; lots of changes. The CW
filters seem significantly better than before. And the SSB filter looks
quite flat.
However, I just installed the KDSP2, and based on the manual the auxbus
isn't communicating with the dsp unit. I seem to be able to use the
default filters, but when I hit "display" I still get the voltage and
current readout. Also I think I was supposed to get a clock setting
routine when I first powered up.
Everything seemed to go together OK, except the width of the socket for
the clock IC is significantly narrower than the IC pins. I had to
actually bend the pins inwards in order to get them into the socket.
That's the first time that has happened.
I am studying the schematic now. Any suggestions?
Also, what happens if I want to do a cal pll or something. Don't I need
the freq counter probe plugged in to do that? Would I need to remove
the DSP unit and then short out the connector where r18 and r19 are shown?
As good as the radio was before the mods, its gonna be a killer once I
get this dsp working. I'm impressed.
Thanks,
Steve, W2MY
