Re: DXing in Indonesia (while living in a "normal" house in a medium-sized city)
Thanks for sharing Frankie! My interest in radio started around 1960, when I was 15 years old. The noise conditions here in Norway at that time was very much like the conditions you describe in Java today. Norwegian broadcasting had just started test transmissions with television. But when I got my ...

Re: Another directional RX loop
anyway, I'm really interested in knowing how well the "squished SULA" nulls out stations so, if possible, rotating it to "null out" a station and reporting results will be really useful and interesting That is exactly what I also have been thinking. But right now I'm recovering ...

Re: Another directional RX loop
If you can/want, it will be interesting to see a video comparing that antenna with the stock one (or with some other antenna) Right now I am in Trondheim, but I am planning to do just that when I return home at the end of this month. Forgot to say that I made the SULA made with some break line had ...

Re: Another directional RX loop
Andrew, I decided to try your antenna idea, and made it pinned to the inside wall up in the loft, using your values for wires resistor and balun, and using a cheap RF amplifier I bought from Banggood: https://www.banggood.com/Signal-Amplifier-100k-6GHz-Full-Band-Low-Noise-9037BAT-LNA-RF-Amplifier-Hi...

Re: Another directional RX loop
Thats a great idea!
Thanks for sharing. This version should be much easier to build for beginners than the SULA.
And a suitable balun and preamp can be found at very low cost on the web.

Re: Balcony antenna
Forty years ago I lived for a year in a small flat on the third floor of a house with restrictions on antennas etc. So I made a similar loop antenna using 3mm copper wire. The circumference was about 9 meters, and I used a resistor of 1 kOhm. Antenna could not be seen from the ground unless you knew...

Re: Balun One Nine: cutting R1
It is done to obtain galvanic isolation between the antenna and radio.

Re: Oddity on WWV's 10MHz frequency June 30, 2022 05:10Z
I just had an eye opening experience. When I commented on 13dka ' recording, I was sitting in a hotel room in Trondheim using my laptop. Think I have to purchase some kind of bluetooth earbuds to get proper audio quality. WhenI listened to his recording again, after returning home tonight, I immedia...

I do no recognise the languageof the announser, but the music in the background is the interval signal of Vatican Radio. I have no idea how this could happen though, so you have probably recorded a once in a lifetime happening.
