CW Audio Band Pass Filter

Recent listening to the bottom end of 40m during the CW section of the OC-DX contest really brought home how close CW signals generally are and just how useful a CW filter would be. A little bit of research led me to the section titled "Inverting Band Pass Filter Circuit" at this site. Specifically this …

2018-10-14 Palm Grove Nature Reserve

As I still needed eleven contacts to qualify VKFF-1983, I risked the rain and headed back. I started APRS at Wyong Railway Station. You can see the slightly different routes to exit/enter the M1 and head to the park here and below. That little detour down Wisemans Ferry Road is because I wasn't paying attention …

2018-10-09 Palm Grove Nature Reserve

This is another of those nearby parks that I'd been unsure about entry to. It's VKFF-1983 Palm Grove Nature Reserve APRS Tracking Again I forgot to enable APRS when I left home. I turned it on when I parked. I left the M1 at Peats Ridge Rd, turned on to Wisemans Ferry Rd, about 100m …

This one (VKFF-0281) has been hanging over me for almost a month. I still had 18 to get to qualify the park so I decided to give it a go today. Today I elected to go to a different area of the park. This time up the top of the hill near Macquarie Park, specifically …

2018-09-14 Glenrock State Conservation Area

I headed out to VKFF-1319. After some discussion with Gerard VK2IO, I decided to use the same activation location. I had some other options but it was not clear if there were breaks in the canopy or safe places to park on Dudley Beach Rd and there were power lines at the Scout camp entrance. Discarding …
