Testing Three Antennas Simultaneously using WSPR with WSPRlite
QRP-labs.com offer a range of cost effective electronics kits for radio hams. I chose to order and build their 20W Dummy Load kit.
The kit is simple to build, consisting of x20 1KΩ 1W resistors sandwiched between two PCBs with a BNC connector. There is also a diode/capacitor circuit for detecting the peak voltage, if required.
Following my purchase of the Sotabeams WSPRlite WSPR beacon a few weeks ago I have just built the optional Low Pass Filter (LPF) kit for operation on 40/80/160m which I will primarily use for 40m. You can see my review of the WSPRlite unit on our club’s website.
K1JT’s superb WSPR protocol has kept me busy/addicted for months, but until recently I was RX only, relying on the global network of other Ham’s WSPR transmitters so that I could spot and report them to the central WSPR database using my station to get an idea of propagation conditions, my antenna performance and just for fun!
For those who have large antennas, it's bound to happen. Gradually over the years you will collect a pile of broken bits. As Brimham hadn't had a go at 6m it was decided that after a session of messing about with a dipole at the farm, it might be an idea to build one using the pile of bits.
The boom was part of an old antenna and the elements reusued from broken parts. Fixings varied, including the use of cable cleats to hold the thinner parts.
It made a session of the UKAC a bit more productive, and where the operation is from qualifies for SAGHOTA.
When you hear a badboy like this rolling up the Dales you make sure of a few things. 1) The dog is safe, 2) All sticky up in the air things are not connected to the rigs and 3) you've got a camera ready! The rain was hammering down when this storm rolled in so I couldn't get outside. As a result I had to take these indoors behind the patio doors - what a show!
For those who care, 24mm, ISO 2000, 5s @ f/16 on Canon 5D mkIII
What happens when you leave a soldering iron in its stand and switched on for an extended period of time? You wreck it, that's what. After donkey's years of service my Weller 60D iron had given up the ghost and I had reluctantly replaced it with an Antex 25W iron which I was almost determined to hate. However, I had to admit somewhat grudgingly, that it did a great job. It was lightweight, warmed up quickly, melted solder and had enough power to do about 99% of the jobs I needed it to - all the things you would expect of an iron.
Always interested in finding new things to read and ideas....so enjoy ....
Google search is useful but if you have a spare 1/2hr and just want something random but of interest to you then there is no better tool than stumbleupon. I just re-discovered it for ham and amatuer radio and have uncovered some real nice pages in the internet. Register yourself, register your interest and then hit the stumble button .... picture example below.
