High Frequency Equipment

I believe I had this dream because last night I was searching information on the Virginia Hotel in Long Beach California and information on the family who owned it, I didnt find any real information about the hotel because it was demolished in 1928 and aparently some tragedy happened there that people dont want to bring up, in any case thats what I went to sleep with and probably thats why I had this western type dream, the family were ranchers.. Last night I dreamed I went to a kind of western saloon and hotel owned by the old guy I knew there who wanted to teach me how to use his AM radio station equipment because he was going to die, so he wanted to teach me in a couple of lessons and he gave me tests about the equipment, the part I most remember was the radio frequency control, which gave you the channel output people were going to listen to, it was a device very, very similar to a Bell Temperature Control, the old man was laying down on a kind of couch while he was giving me these lessons and he wanted me to learn fast, he got upset everytime I confused anything...
