Likewise the Hardware section of the WXtoImg website has many good 137MHz designs, of which the Quadrafilar Helix antenna is generally acknowledged to be ‘king’ of 137MHz satellite receiving antennas (in fact the NOAA satellites themselves transmit their APT signal from the spacecraft using a ...
Just when I thought my bargain day was over I noticed something interesting. It looked like one of those typical 1940’s combination record player/radio combinations. I was attracted by the cabinet and front dial, both in pretty good condition. Upon further investigation I found that it was a...

From FT4GL’s log he’s operated automated FT8 24/7 for days on end. A quick look at any day of his TXTpedition shows his computer scripts rarely stop racking up the Q’s. Eat? Sleep? Build antenna’s? Work?All overrated.
The other day I noticed a very interesting photo on a fellow Australian ham blogger,Peter Mark’s site. The blog entry was titled a “Radio nerd’s tour of Canberra“. The first photo is described as ‘a transceiver with a nifty antenna tuner’. But the instant I saw it I sensed ther...
Here’s a picture looking straight toward the back of the building, with a vendor selling some sort of antenna at the foreground. Apologies for the blurry photography — the lighting was low and I had never used this particular camera before. ...
Why the Basic Pacific Antenna Kits? I first became aware of these excellent basic kits a few years ago when we chose the Easy Receiver kit as a group build project for a Wednesday Workshop at the Yale Center for Engineering Innovation and Design that we, W1YU, the Amateur Radio Club at...
