Believe me I know that ads pay for this site and it's important that we view them, but on mobile maybe I'm doing something wrong, but viewing it through a browser on mobile I am completely covered in ads. I mean you click one thing on this forum and boom you have ads top to bottom that cover the...

So one of my best friends in the world recently fell ill. He suffered an enormous stroke about 2 weeks ago. He's in the hospital right now and if he recovers this is going to be some journey. If you guys could take a minute and just look at his GoFundMe and pass it along on your social media I'd...

Where is everyone picking up 8v for their echo boards?

Anybody have any recommendations for any mail in shops? People that don't have a one-year wait list that do good quality work?

Maybe some greybeards on here remember when choke input power supplies were the norm. Every amplifier had them. The wisdom that was preached is that they offer better regulation. I worked on plenty of amplifiers with them both large and small. The largest supply I've ever used with a choke input...

Anyone know if Lee is still in business/ building antennas?

I was told a story about a Cobra 29, you were able to broadcast on every channel simultaneously. It's just a goof. Is it as simple as making the pll unlock? Will the radio still function on receive? How would one modify a Cobra 29 to do this?

Probably over a decade ago I remember looking at a website and this gentleman did something very clever. He had a couple of stacked Yagis on top of a tower, each one covered a different band.. but he did something with a box with a bunch of relays in it where I think what he did was disconnect...

I've been thinking about mounting a roof mount sirio antenna on one of my vehicles. I like the size of the base and I like the fact that they have their own internal matching device so they do tend to tune very well. I have not been impressed with the quality of Wilson's in recent years. All...

Even though the yaesu 101 is an ancient radio by today's standards they still get used, traded, and sold. In fact, I'd argue they are an easier sell when they are in working order than loads of their more modern counterparts. There are a handful of places that still repair them as well which is...

I have a Johnson valiant. I no longer want said Johnson valiant. It was a project I never attempted. It was never on in my presence. The good: I have everything, I think. All tubes tested like perfect condition, I also have the original rectifiers and the solid state replacement ones. I also am...

Anyone know where to get one? I had a straight,non coiled cord years ago with a male and female 4 pin on it. It was great. Anyone make them? @nomadradio , I'm looking at you.

I can think of nobody specifically to pose this question to. I have seen mention on various electronic forums and I think this one as well, a technique of using the secondary of a second transformer, just the secondary I think, in series (I think) with the primary of a high voltage transformer...
