I'm here scratching my head how best to approach this.
I have an old MW/LW valve radio which I repaired many years ago but rarely use it now. I have to switch it on every so often to stop the capacitors from deteriorating. So I may a well use it rather than let it just sit there.
MW is now switched off in Ireland and LW seems to attract every kind of possible interference. I have been toying for some time with the idea of making some sort of FM receiver and feeding the output into the aux input of the radio. How difficult would it be to go one better and make a combined FM receiver AM transmitter and place it near the set but use a separate power supply. I am quite willing to use any modern devices (IC's etc) which can make this task simpler but want to preserve the sound quality as far as possible.
