Straight Key Night

December 31, 2013 Leave a comment

Tonight is Straight Key Night when many SKCC members will be on air particularly in the USA on 80m. I plan to listen out for them and see if I can bag rare 80m DX. I do have to get the 80m vertical loop fixed today so that will be a priority today. Unfortunately my 80m loop faces the wrong direction for USA but will give it a go anyway.

Here is a video from the US regarding SKN

Solar Update from SolarCycle 24.com

Solar Update – Solar activity remains low but that could change should two new sunspot regions continue to grow. One of these regions is located in the northern hemisphere and is now the size of atleast 3 planet earths across. Another region is now rotating into view on the southeast limb. The sun currently has 5 visible sunspot groups. There is a chance for C-Class flares.

10m Band Open Yesterday-PSK PropNet Log

Yesterday it was great to see the 10m band open again. I got a new country- Cuba. I also made a few other contacts into USA and Mexico.

My PSK signal was recorded by PropNET

PropNET is a system for analyzing and recording HF and VHF circuit quality. It uses a
distributed network of PSK31 stations automatically transmitting and receiving messages
and reporting them to a central database, where real-time displays and statistical analyses
are generated. We’re interested in real-time propagation detection and long-term analysis
of circuit usability, and other interesting uses that the combination of radio and computers
can facilitate.

Tracking Aircraft for AE

 

One area of interest to ham radio operators is aircraft enhanced DX on VHF and UHF. A great aid to this is a piece of software called PlanePlotter available from http://www.coaa.co.uk/planeplotter.htm.

I’ll attempt to provide some more info shortly, but for now have a good read of the website.

I made a nice PSK31 QSO with OH4TI, a great example of greyline propagation
