Hi Bijendra,
it's not quite clear what your question is.
A couple of things you might want to consider:
- AM is per se noisy. A commercial HF receiver would also have much
better filters than you can achieve with an LFRX-only setup, so expect
much noise here
- FM is much better with noise.
Great idea!
In fact, it's so good, it's already been implemented:

Dear community,
at the last GRCon we discussed the user experience regarding GNU Radio.
A pretty huge group of people came together for a very productive
discussion on how the user experience can be improved.
Our method of choice was to go through the life cycle of a GNU Radio

Hi everyone,
following GRCon '13, we had a one-day hackfest. A *lot* of people stayed
around for this, improving GNU Radio on all fronts.
Since there has been a request to know what we did, I have started a
wiki page:

Hi Jared,
this is how the XML validation works, yes. It's probably just an
artifact of whatever XML parser we're using, but we've all gotten used

You could rewrite the blocks for fixed lengths. Out of the box, no, you

Don't worry about these blocks, they are just to make the Figures look
complete (or rather, to label the inputs).
Hi Jared,
thanks for oiling our module. I will look into this soon, maybe we can
merge your stuff back into our repo.
