Hi all,

For the life of me I still can not figure out how to properly build an AM
and SSB receiver. Using grc I am able to build and run FFT sink and observe
the AM broadcast band spectrum and control the frequency.  But I can not
detect the audio.  (I have not yet tried to build an SSB receiver.God
I tried various filters and AM DEMOD. When I install the AM DEMOD I keep
getting an error message "number of taps must be >=3." Can anyone tell me
how to build an AM/SSB receiver using grc?  I have searched the web but
haven't found anything.

Searching the gnuradio directory I found hf_explorer, hf_radio and
usrp_am_mw_rcv.py. These files appear to be what I am looking for but I have
not been able to figure out how to install and run them under python. Can
anyone instruct me on how to get these files/programs up and running?

I have spent hours and hours trying to figure it all out (and searching the
web)but so far I haven't been successful. Is there any way to get an HF
receiver up and running without the need to become an expert in python, C++,
etc?  I do want to learn to use python, C++, etc so that one day I can write
some blocks but I would like now just to get a receiver up and running to
play with.

Thanks for your help,
