It's a good video as is. I read your post before playing the video, so I was not only forewarned, but was waiting to hear the objectionable (to you and no doubt some others) word, but I didn't hear it. I had to replay it with the volume well above normal listening level to hear him whisper under his breath the word. Just curious: did you ever serve in the military or hit your thumb with a hammer? Think anyone finds a key word in your street address vulgar slang when writing out a QSL card for you?
Have one very similar to yours. If you look at the photo from the Amazon link to the extreme left there is a green LED next to LED is a DC voltage adjustment. I forget the exact range. Just had a problem with an Astron and had this PS on the shelf. Seems to work fine, very little voltage drop use it with my 630 meter station.
