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.

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...

Just scrape it off whith a knife... Carefully!

Good luck!

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.

Paul, When I moved to my present home I had excactly the same problems. After a lot of trial and error whithout any improvements in the noise situation, one of the oldtimers recommended a "Common Mode Choke". He even built it for me. That got rid of almost all the noise, and still works fi...

Some years ago I had exactly the same problem as you. A friend adviced me to build a simple antenna tuner, and a quick search on the internet resulted in a link to a building instruction for an antenna tuner in PDF format by someone calling himself Editor Bob. Since then I have built two more of the...

Never used a MLA-30 myself, but today I more or less stumbled over this discussion where they also have published schematics for both loop amplifier and bias-T:

Good luck!

If you were happy with the PL-880, the 990 (or a 2nd-hand 880) might be a reasonable replacement. The S-8800 is the only of the two I own and I found it a particularly quirky radio, it's also quite big for traveling with it. Thanks for posting your opinion on the S-8800. A few days ago I visited a ...
