[hpsdr] IPhone SDR Application

[John Melton]

Richard,

I will try to build ghpsdr on my Mac again and publish the details.

The latest iPhone software allows better access to the accessory socket 
which does have stereo line-in.  I have been trying to find an adapter 
that would let me connect to this input but so far the only one I have 
found is a very expensive stereo microphone.  I am going to try to get a 
connector and make my own dock on a softrock receiver to see if I can 
get something working.

Based on some software I have that does spectrum analysis of the audio 
input I think it should be capable of at least being a fairly reasonable 
receiver.

Regards,

-- John g0orx/n6lyt
