Good morning.

I've just completed the assemble and some initial testing of the

SoftRock40. The green led lights up and the Fixed HW Osc @ 7.056MHz
can be seen and heard. That's about all that works since the
SoftRock40 does not appear to be receiving any signals from the
antenna. There are two issues/questions follow:

ISSUE#1: Under "Configure & Use", step#4 is not clear. It says "

With the oscillator running, tune to the frequency that is as much
above 7.056 MHz as the test oscillator is set below 7.056 MHz."

I'm not sure what this means! Does this mean that an external

signal generator should be connected and tuned to (7.056MHz -n),
while the SoftRock is set to (7.056MHz +n)??? Please explain.

Correct. You must inject an external signal here. I use an XG-2 from
Elecraft. Another good method is to take your HF rig, and transmit
into a dummy load while listening on the SoftRock. If you transmit
on 7.046, you should see a signal on the panadapter display near
that frequency. You should then also see an "image" of that peak
somewhere near 7.062 on the panadapter. THAT is the peak you will be
trying to null with the DSP image reject controls.

ISSUE#2: I'm not able to null any images under "images" as

described in step#4. (In fact I do not see an image, only the
7.056MHz test signal.)

Until you get a signal into the SoftRock, there won't be any images
to null out. But, I would have expected some signals to appear on
the panadapter when you connected an antenna. You might want to
start by double-checking all your soldering and component placement.

I hope my explanation of the nulling procedure helps, and good luck!
