Combining “QRP Hours” contest with WWFF activation at Mundoonen Nature Reserve

After a failed activation of this reserve a few weeks earlier I wanted to get some contacts for this reserve into the log.  The QRP Club’s QRP Hours contest on 22nd October 2017 seemed like a nice opportunity.

I set out from Yass about 45 minutes before the contest start as I had a good idea of where I would operate.  On site I found I had to be satisfied with a sloping site and I put up the usual linked dipole with all links connected, giving 40m operation.  I decided to use the MTR3B CW transceiver for the CW section of the event and use the FT817 for the SSB section.

The MTR3B transceiver’s principal characteristic is its compact size and low power usage in particular on receive mode where it is about 40 milliamps, about 1/10th of the FT817.

However the inability to conveniently and rapidly browse across the band looking for other stations calling CQ is a limitation for contesting I had not really considered before.  Nevertheless I persisted with it to try and find a way to use it best.  I had not yet used the Direct Frequency Entry function and I really needed that, so I could jump back to a starting frequency.  Also I had not recorded anything in any of the text memories.  So during the contest I opened the LNR website and read the instructions for storing text into one of the memories.  The obvious thing to have recorded for quick playback is the CQ call.  So at least I achieved that during this event!

During the CW section I made 5 contacts but of those only one was within VK2 and that was with Mike VK2IG, who with partner Helen VK2FENG was portable in another WWFF nature reserve, not far away from me, but far enough to sound distant.  No AGC or even AF gain control on the MTR3 – I have a volume control in the ear buds lead. Other contacts were with VK3, 4 and 5.   There was no “normal” NVIS propagation.  Very pleased to have worked Warren VK3BYD/5 somewhere in the middle of South Australia, and Grant VK4JAZ who was operating from home in Brisbane.  QRP is a combination of frustration and achievements.

After a half hour or so, I got a reminder that I was operating in a nature reserve, in the form of a sudden downpour of rain that became hail for about 10 minutes.  Fortunately I had suspected rain was imminent and had erected the “sun shelter” shortly after the start of the event.  But the slope of the operating location meant icy rainwater was running downhill and under my seat, a small foam sleeve sold for protecting computer tablets and small laptops.  Before long the whole site was wet and cold and my clothing was drenched from the waist down.

The SSB section commenced at 0600 UTC (5pm local) and after working Helen VK2FENG nearby, Laurie VK5LJ and a few more, I ran out of potential contacts.

At that point, a lull in the rain seemed to have arrived so I decided packing up and leaving would be prudent.

Half an hour later I was enjoying a very welcome warm shower at home.

Fortunately my log is not important for the QRP Hours contest other than a check log, as I am the contest manager.  I’m glad I was able to add a contact to a few other logs and in the process I did activate the WWFF park, though with insufficient contacts to qualify for any activation points.  That’s ok, this park is near to my home and I will return, hopefully in dry weather.
