The 'Redirad' and similar devices sound (pun intended!) like a very good idea, allowing the connection of all sorts of external devices withouth the need to remove the radio for internal modification. Years ago a similar technique was employed to allow an AM radio to receive FM stations, admittedly only in mono, and converted to AM. With the 'Redirad' it would appear that the same principle is used, presumably by Amplitude Modulating an internally generated 1000kHz signal with AF from an Ipod or other device. Again, the resultant audio is only going to be mono and with a max. frequency response of no more than 5kHZ, at least in the AM version.
