Subject: [softrock40] softrock40 not working!

Hello Folks,

I just got my Softrock40 kit assembled. I also wrote a GNURadio
program to tune around the +-24khz BW. I plugged in the board and the
green LED glows, but do not hear anything. The coax is not connected
to the antenna. I checked the signals on clocks with my scope (which
cannot accurately measure the frequency at the moment, but there is a
signal there).

Since I do not run Windows at home, and since I do not want to have
too many variables, I am at another place which has a WinXP machine. I
installed all the software (rocky, powerSDR, powedSDRconsole,
sdradio). Currently I am using sdradio to see whether some signal is
coming out. I just cannot hear anything other than the carrier at
7056000, which happens to be there even when I take the audio cable
out of the soundcard input.

I do not have any other signal generator like the XG1 being used by
many of you. Is there some way I can verify that the hardware is
working?

Check the coil connections Those are the most likely cause of the problem if all the solder joints are OK.

If you have a 40m Tx you could use that for testing, or make a simple test oscillator if you have a suitable crystal.

73, Leon
