		<description><![CDATA[Operating in the QRP Hours contest in April 2011, using an antenna set up in the hours preceding the contest.  Le Mans style radio contesting!]]></description>
			<content:encoded><![CDATA[<p>This is a short contest for QRP operators.  It runs for one hour on CW mode, then 1 hour on SSB.  A truly easy contest to participate in.  All licence classes can participate as QRP (low power) or their ordinary power.  The contest was sponsored by the <a title="CW operators QRP club" href="http://home.exetel.com.au/auriga/AR/QRP/QRP_Hours.html" target="_blank">CW operators QRP club</a>.</p>
<p>I wasn&#8217;t sure I would have an opportunity to operate in this contest but at about 6:30pm on Saturday 2nd April I decided I should put up an 80m antenna and have a go.  At 6:40 I had identified a two section telomast and was measuring out some guy ropes for it.  Having found some stakes, guying ring and found the wire antenna cross-boom with the attached halyards and pulleys, I was able to assemble the mast, attach the cross-boom, lay out the guy ropes and do a trial setup to get the guys set to the right lengths.  Once that was done I hammered in three stakes and attached the guy ropes to two of them.  Walking the mast up to vertical showed I had set one guy at an impossibly long length so it all had to come down.  Next time was ok so I could walk the third guy out to the stake and tie it off.  One 20 ft feedpoint suspender ready for action. Time about 7:15.</p>
<p>I had a 80/40m dipole assembly last used two years ago at a rental property in Canberra.  I attached the centre conductor to one of the halyards and hauled it up to the dizzy 20ft height of the mast.  Then I attached some light cords to the antenna ends and tied it to the fence at one end, and to some ground stakes at the other end of both dipole wires.  This work was completed in the dark as the sun set at about 6pm local time.</p>
<p>The two dipoles are joined at the centre.  This works because the 80m  antenna is a very high impedance on 40m, so is virtually &#8220;not there at  all&#8221;. The 40m dipole detunes the 80m one slightly but I went through the  adjustment process with this antenna about 20 years ago and have simply  rolled it up when I finished using it each time.</p>
<p>Then I got out the FT817 and found a suitable keyer cable, microphone, power supply.  On 80m the dipole presented a 1:1 match on the CW end of the band so that was fine.  On 3690 it was about 1.3 but my Emtron tuner handled that mismatch with a fairly broad dip.  The time now was about 19:45 local and the contest started in 15 minutes, or so I thought.</p>
<p>At 20:00 local time I heard a station calling CQ TEST so I answered, received a number, gave a number, signed off.  Good start to the contest, I thought. Then I called CQ TEST myself.  No replies.  Tuning around showed nil activity.  Called CQ again.  This time I got a reply from an operator who kindly advised me that the contest was not due to start until 2100 local time.  I opened up the computer and checked the contest rules.  Start time 1000 UTC, which was 9pm local, but somehow I had reverted to non DST in my calculations due to daylight saving ending later that night.  1000 UTC was almost an hour away.  So I had time for some dinner!</p>
<p>About 45 minutes later I went back to the radio and started the contest again at the right time.  Signals were strong and most stations were in the vk2, 3 and 4 areas though there were some vk5, vk7 and ZL stations worked too at signal reports of 559 or so.  I made 10 cw contacts in this hour.  A slow contest compared with the DX contests but it was also quite relaxed and unrushed.</p>
<p>At 1100 UTC the SSB section commenced, operating between 3550 and 3590. Signals were very strong from some stations.  Again a few names were exchanged as well as the contest numbers.  15 contacts on SSB, and I got the impression the antenna was working well, as mostly my replies were answered after only one call.  Quite good for a 5 watt signal.</p>
<p>I have sent in my log and I don&#8217;t think this is the only QRP event I will operate in.  This was a very enjoyable process and quite rewarding for the minimal effort required to get on the air.  Next time: antenna up another 10 feet.  And the ends should be higher too!  Should be no problem.  I might even do most of the work in the daylight next time.</p>

			<content:encoded><![CDATA[<p>For this event I took my usual station on 50 to 1296 MHz, plus my transverter and gridpack for 2403 MHz, Ted VK1BL&#8217;s transverter and gridpack for 3400 and Dale VK1DSH&#8217;s 10 GHz station (IC202, transverter, dish and tripod).</p>
<p>Contacts were made on all these bands.</p>
<p>Performance of the station on 1296 MHz was not as good as in previous years.  This may be due to conditions, or to a problem with my antenna or my location on Mt Ginini.  It is becoming increasingly more difficult to find suitable places where even two required directions are not partly blocked by the trees on that mountain.</p>
<p>Some pictures are already on <a title="http://www.flickr.com/photos/exposite/sets " href="http://www.flickr.com/photos/exposite/sets ">http://www.flickr.com/photos/exposite/sets </a>and I&#8217;ll be putting some also onto the vk1da.info photo pages.</p>
