Stumbled across Burt K1OIK on YouTube and some of his videos on Ham radio and tube gear that I found rather interesting to say the least. Just keep in mind that he has a very dry coarse sense of humor that a LOT of people take the wrong way and attack him for it. Nonetheless he is an internet sensation for Ham radio.The Video here is on using an old Hallicrafters SX-76 receiver with a heath-kit DX-40 transmitter. One thing to note is that he is not quite using the receiver properly. He has the RF gain up a little high which gives the received signal that watery sound. Usually on these older radios you would bring the RF-gain down while bringing the AF-gain up since these older radios didn't have AVC.
Other than that he is a great source of videos on older radio gear. A lot of his videos are demonstrating gear he has for sale.
