Just Get On The Air! (A Makeshift Temporary Dipole Shortwave Antenna)
It might not take as much antenna as you may think would be necessary to make two-way contacts on shortwave radio (as an amateur radio operator putting an HF transceiver on the air). However, often, makeshift antennae are effective enough to be viable–just look at all the contacts many amateur radio operators make with their low-power (QRP) rigs (transceivers) using short, helically-wound, mobile antenna sticks. If they can work magic with such inefficient antenna setups, surely your effort at an antenna would pay off to some degree. Right?
Of course, I want to make a proper dipole out of this example antenna. But, while I wait for the rest of the parts I need to complete this antenna project (pulleys and a ladder, and maybe a potato launcher), I’ve put this makeshift antenna on the air, with it just high enough so that I can enjoy some time on the shortwave bands.
With this antenna, I’ve made successful two-way voice and Morse code contacts (QSOs) with stations in Europe and across North America. I am able to tune it on the 60-, 40-, 30-, 20-, 15-, 17-, 12-, and 10-Meter bands. Reverse beacon detection picks up my Morse-code CW signals, especially on 40 meters (the band on which it is tuned physically).
The bottom line: just get something up in the air and start communicating. Improve things over time. You’ll have much fun that way.

Things I’ve learnt this week
1. A clicking noise from a hard disk doesn’t mean anything good.
2. This stack of part finished or finished bu not boxed up projects needs to be dealt with over the Christmas break if not beforehand or the XYL will go bananas.
3. Must not buy any more bits and pieces off Hans Summers, G0UPL (http://www.hanssummers.com/index.php) until I’ve completed all of number 2. Oh apart from the gps and replacement pa’s for my QRSS transmitter.
4. The UKAC contest series is short, enjoyable and keeping me close to a mic but isn’t helping with getting on HF.
5. No matter how much I think they’ve started, there are no builders in the back garden working on the extension. This is all very well as its not costing me anything but it means there is no tower up.
