Re: Brimar or Mullard 12AU7 Tubes
I don't know much about tubes (like if this is what you are looking for)... but Rich Hozjan may have 1 or more.

Wow, that Ellington video was really impressive. That guy knows his stuff and I learned a lot watching this. It’s long but was worthwhile. He reviews many antennas and speaks from experience. My

Re: Antenna for my Sony reciever
I have a little Grundig that is, I think, in the same sort of class as your Sony. I’ve had good luck with a simple long wire antenna. A dipole might do better but the first thing you might try is

Antenna for my Sony reciever
Hey hiya snovarcians,
I have a couple of Sony ICF-SW7600GR radios I keep for emergency receivers. I have an external antenna jack and thought of making a simple dipole.
I have ferrite beads on

Re: Rowlands reflector question
There is also a Facebook page "End Fed Half Wave Antenna". Once you join look in the files section. The one page direction can be viewed in the link to the YouTube video. I can send the file once

The easiest way to get on the air is using what many SOTA operators use. A resonant end fed half wave antenna using a 49:1 transformer. You can buy on line or easily make your own. With 131 feet of

Re: Rowlands reflector question
I’d be inclined to put up a 135’ long OCFD if you have the space. I like the Buckmaster one because it’s pretty bomb-proof but it’s not magically better than all the other variants

Re: Rowlands reflector question
As mentioned there are several options. The easiest would be an end fed zep. Not the best option but will work. I have used one on several occasions in the field and had good success. Get one end up
