Active 3-30 MHz Hula-Loop Antenna for Shortwave

I found this site a interesting hf loop antenna.

Antennas


Home-made antennas can greatly improve the performance of AM and FM radios,short-wave receivers, and scanners. If you are a talk-radio fan then experiment with the AM band antennas and you will be able to hear shows from all over the country with surprising clarity. Short-wave receivers are always coping with weak signals and they must have a good antenna to perform adequately. Scanners can pick up local police and two-way radio with the little telescoping antenna provided but with good antennas a scanner becomes an amazing ear on the world nearby. No pre-amp, filter or other receiver refinement offers anywhere near the level of performance improvement t that a well-designed antenna offers. The results can be quite satisfying, leaving no doubt that the project was well worth the effort.

Juma RX1 Direct Conversion HF Receiver with DDS VFO from OH2NLT and OH7SV

Hi this is my latest little project and I have just completed building it and I have to hand it to them the quality of the kit was very good. The parts were well identified and well packaged. Don’t let the SMD components put you off this kit with a little time and a quick searching on utube you will find lots of demonstrations of handling and soldering SMD devices.  I will post a Picture of my finished radio later in the day ;)

IGEN Regenerative Receiver Kit


This is my latest little project a kit I found from
http://www.6v6.co.uk the
Tube Regenerative Receiver with Solid State Amp IGEN.
It's a good little kit to get started with fiddling with valves no nasty HT. I have also purchases the HF coil kit as well and got it working receiving 3.5MHz to about 8.5MHz ideal ;)
