The things you find

I was in the garage at my parents' house recently and I found an old radio that I used to have many years ago. It did not cost much money, but I always thought it looked very smart, with lots of dials and a magic tuning eye that turned bright red with a strong signal. So, I brought the radio home and forgot about it. I noticed it again on Saturday evening and switched it on. It worked! So, I placed my small indoor loop antenna next to it and tuned to the top of the mediumwave band. I did not expect to hear any pirates as most domestic radios do not go much above 1620 kHz. However, straightaway I heard a very strong signal playing music from Koto. It was Calipso on 1656 kHz!
