swl

so i built this linear loaded SWL antenna, a project i found on the swling website, which involved getting a a NooElec 9:1 balun in the middle of two 15ft pieces of romex bound at the ends in a way that it effectively makes a dipole with 45ft elements. this balun is not made for any kind of...

Hi All, I'd like to install a dual band base antenna (likely no more than 50W at max output) for reporting in to my Skywarn Net and ragchewing. I'd also like to put up a discone or similar wideband RX antenna for monitoring Aircraft, Marine, RR, etc. I'm assuming I can't put them right...

Greetings, I have found a site called websdr.com where you can SWL without a radio, Its streamed over the web, I use this frequently due to the fact that I am a renter and my landlord is not exactly warm to the idea of me putting up an antenna or three.luckily I can get away with a 2 meter...

Hi! I recently found my oldish Grundig G5 receiver, and thought it would be fun to start listening to shortwave again. I used to live in the country and I had decent reception, but since moved. The antenna was very loose and I had terrible reception. The rubberized coating had also become...

Hello all, I have been a ham for 20+years, and recently became interested in short wave listening. I have decided to purchase an SDR radio, either the Perseus, the Win Radio DDC or the Bonito Radio Jet. None got good reviews on eham, as hams were only using them for ham related uses, not...

Hi folks, I'd like to share this video I recently put together that demonstrates how one can use Software Defined Radio to receive HF. I analyse a number of interesting/unusual signals (e.g. STANAG, DRM, OTH RADAR) by putting them through various pieces of software (e.g. HDSDR, GNU Radio...

My wife and I live in a condo and I'd like to improve my antenna setup for my SWL. I live on the top floor of a two story condo unit in the far southwest suburbs of Chicago. I have access to the attic which is built out of conventional trusses. My unit, and therefore my attic access is about...

Hi all, I was just wondering what kind of signal difference I might notice by re-orienting my PAR End Pedz SWL antenna. Right now, it's in a sloper config pointing north-south. Would going east-west significantly improve signals in those directions or would it be only a minor improvement...

I would like to know the mode in which Broadcast shortwave signals are transmitted in, beceause I have the Eton/Grundig mini 300PE( http://www.etoncorp.com/product_card/?p_ProductDbId=6289 ). This is basic shortwave receiver but the "41meter" band fully encompasses the 40 meter amateur band...
