Reminds me of my early days when as a lad, I spent all my savings on a
brand new Johnson Viking Thunderbolt to go with my Ranger. Since the
piggy bank was empty, I decided to use RG-59 since it was so much
cheaper than RG-11. Everything was OK as long as I was on CW, but when
I ran the T-Bolt as an AM linear at about 500 watts, I noticed the RG-59
got pretty hot. Sure enough, one day after a long-winded QSO on 15 mx
AM, the dielectric melted enough that I got a direct short with all the
I learned my lesson and switched to RG-11. Try as I might, I never was
able to melt RG-11 with the T-Bolt. That came with later home brew
