Over the past few weeks I have been running a WSPR transmitter, using 50W predominately beaming toward VK2. An interesting thing occurs on this path.
These are the stations that have heard me:
VK2HC: Once (1081km)
VK2DVM: 3 times (1095km)
VK2ZMT: 22 times (1189km)
VK2XN: Once (1443km)
What is interesting about this, is that it is currently Spring and not in Sporadic E season. The approx midpoint of most of these paths is over the Australian Alps. It's not uncommon in summer to see stations on this path very very strong. In fact they are probably the strongest 6 metre stations during E events. But what about these events out of season? Are they random Sporadic E clouds forming? From the data that I have, I can ascertain that spots were received by the VK2 over at least three separate days, and I recall at least two days in a row where VK2ZMT was hearing me.
I recently come across this video on YouTube from the RSGB: https://youtu.be/wn5as91ndG4
Watch the whole video but if you skip to 9:12 the speaker talks about "mountain waves" which may be a contributing factor to Sporadic E. An interesting theory and thought.
A truly exciting announcement from Icom at the Toyko Hamfair 2019!! The new Icom IC-705 was a topic of discussion and review at a recent experimenters night at our local ham radio club.
Rex VK7MO, Justin VK7TW and Hayden VK7HH gave their thoughts on what this new Icom IC-705 radio can mean for the QRP, microwave or SOTA operators. Some features like a large touchscreen just like the IC-7300 or IC-9700 will appeal to users who already own one or both of these radios.
Yes the Icom IC 9700 has been GPS locked! How? Well Rex VK7MO brings us up to speed on developments, explains the features he enjoys most out of this new radio and the benefits for those wanting to use this rig on Earth-Moon-Earth (EME) moonbounce or other weaker signal digital modes.
Today I traveled to the site of an amateur radio repeater on UHF (70cm) that I maintain after a fault on the transmitter appeared and gradually got worse over the past few months. Lesson learnt - always bring EVERYTHING you may ever need!
