Antennas / Re: Windom Antenna Analysis With The MR100.
« on: March 03, 2018, 09:29:28 PM »
* WinPCC-Sark100.exe.7z  Downloaded this file but my Winrar is reporting the file is corrupt. :( Anybody having the same issue. ???

I am on a Mac and cannot really do much to help. The file downloaded OK, but cannot be opened on a Mac. Try removing the suffix ".7z" before opening, so your PC understands it's a .exe file may help.

I also read somewhere the 817 has a built in antenna tuner

Are you certain? If that is so, why did my ham radio vendor insist I needed this one?

I show here two of the best radio receivers made during WW2.
E52b and Lo6K39a.
Lo6K39a is probably the world's best TRF receiver.
E52b is the best receiver made during the war.

BTW - is there a place to look up SW transmission information? That is a list of transmitters on the air.

There certainly is! I bought my very first edition of this outstanding book some 55 years ago:

Morse Code / Learn Morse Code in 20 Lessons (Koch Method)
« on: September 20, 2017, 12:53:07 AM »
You want to learn Samuel F. B. Morse's (shown above) most famous code. The South Canadian Amateur Radio Society (SCARS) wants to help. Mark Kleine N5HZR developed this series of web pages to help you learn the 40 characters of the International Morse Code in about 20 lessons. Additionally, you can continue to practice hearing your code for another 20 lessons. In the first lesson we introduce two characters, the letters K and M. Think of this as if you're learning the sounds 'momma' and 'dada', as an infant. You'll listen to these characters, learning to hear, and differentiate their two sounds. Then, you'll come back each, and every day (or two) and listen to 2 new characters in 5 lessons of 5 minutes each. You don't have to listen to all 5 at one time. You can listen to a couple the 5 minute sessions at breakfast, one at lunch, and the last two in the evening. Make each lesson enjoyable, and you'll have a better experience.

Each day you'll build on the characters you already know. During the first week, you may feel frustrated or you may have trouble hearing each individual character. However, by day 5 or so, you will start to notice that the characters are 'slowing down', and you can differentiate the characters. In reality, you're simply learning to hear these tones quicker.

You should concentrate on how each character sounds, and don't rely on a visual representation of the code. Listen to the characters, and hear the rhythm of each one. You will hear Morse Code sent at 20 Words Per Minute (WPM), sent at full speed, from the very first lesson. These tones are purposely sent too fast to count the beeps. You should be training your ear to hear the sound of the character, like you hear the sound of a word. Listen when you are able concentrate on what you're doing, and not overburdened with other activities. Remember, this should be fun. Enjoy the process. So, when you're ready, sign up for the free reminder emails right here, and start with lesson 1, we hope you'll make it through the 40 lessons, and LearnMorse!

The best way to learn Morse Code is to spend 30 minutes a day listening to code. The best way to make that happen is to have someone else remind you to do it. Enter your email address, and click SUBMIT to start receiving these messages.

Radio Reviews, Questions and Comments. / Re: ELAD FDM-DUO Transceiver
« on: August 31, 2017, 12:41:36 PM »
Summer is soon over, and I finally decided against buying this fine radio, even at the 25% discount.

Main reason: I don't (yet) fully understand this SDR-stuff, and feel I don't need it (yet).

On top of that, ELAD delivers PC/Windows-only solutions, and I have used Mac only on a daily basis since 1989.

The transceiver used in there is a Hendricks PFR-3A, and I wanted to know more about it:

First: Interesting background on the PFR-3:

These are about the PFR-3A:

Seems the current version is Hendricks PFR-3B, which I found here:

Funny site but very annoying popups that were impossible to dismiss until I gave them a fake email address.

Thanks cockpitbob for the picture, I have seen it a few years ago, this time I stored it for future reference.

I assume they are in the U.S., but I can't find where they are located.

I also wondered about that. This is what I found out. The owner of QRP Labs is a British ham:

Check Podcast Episode #125 here:

As a 2009 QRP ARCI Hall of Fame inductee - Hans Summers, G0UPL, is an electronic experimenter and amateur radio innovator extraordinaire. Hans pays careful attention to compact and minimal parts count to achieve the design goals of his homebrew projects. Hans is the owner of QRP Labs joins Eric, 4Z1UG, in a conversation about QRSS slow data transmissions, high altitude balloon transmitters, and shares his ham radio and electronic builder story.
