  To access movies and TV shows. 1 Need USA VPN to access blocked torrent sites. Either expressvpn or nordvpn. Nordvpn is best for UK TV. They are both about $100 per year. You can use them for streaming. However, you can use a free one just to access torrent sites. 2 Install utorrent.  3 Check the torrent sites Magnetdl (check movies or the shows for the latest or search for old ones), YTS and Torrentgallery for current movies. 4 Click the Magnet link to download the file. Utorrent handles it auto. Files are in downloads. If you move the file while utorrent is running, right-click in utorrent and click "remove" to cut file link to utorrent. 5 Plex is an excellent way to access stored movies. But it takes a bit of setting up. There are Plex apps on all streaming boxes that can be linked to Plex on your own computer. Just run the Plex server program. There are lots of tutorials for Plex on the web. 6 Without Plex, just click on the file using file explorer. 7 If you have probl...

Starlink Satellite Internet Gold Coast Queensland Australia My Starlink satellite internet order arrived a couple of days ago, February 2022, after a wait of about nine months. I think the wait was due to my location being serviced by Starlink. I set it up in the driveway temporarily and it worked very well, up to 250 Mb/s downloads. The antenna is now installed with a view of the sky above the house roof and connected as the main internet, replacing the slow NBN FTTN (Fibre to the node, VDSL). Cost The cost in Australia is about $800 for the hardware, then $139 per month. The monthly cost is reasonable given that we pay $100 for Telstra NBN FTTN. I will continue the NBN for a month or so, to make sure the Skylink is reliable enough. Mounting The Skylink antenna needs a clear view of the sky as the low earth orbit satellites can be anywhere in the sky. While the antenna is a circle and looks like a dish, it is made up of about 1000 small electronically steerable antennas using beamform...

 Low-cost duplexer for 6m, 2m or 70cm I am proposing a conceptual design for a low-cost, home-made duplexer for 6m, 2m, or 70 cm. I have not built one to this design but it combines ideas from duplexers I have made or from commercial duplexers. It is worth reading this post in conjunction with my other posts on cavity filters and duplexers; just search the terms. I have written a guide to how duplexers work and have a list of resources on the building and testing of them. https://vk4zxi.blogspot.com/2018/05/the-black-art-of-duplexers-demystifying.html General arrangement The basic design of a single cavity filter is a large diameter aluminium pipe for the cavity and a 1/3 diameter aluminium pipe welded to a top plate. The coupling is mounted on the same plate. The other end of the large pipe is held to another plate by bolts for access. A capacitive hat on a threaded rod is mounted on the bottom plate to tune the cavity. The main pipe is as large as possible to increase the Q of th...

It explains how the M1 chip is such a radical change to current PC hardware. However, the one thing he doesn't say is that it may not be that hard to run Windows on the Apple M1 machines. Microsoft already has a version that runs on similar chips designed by ARM, as used in the Apple M1. With Windows on the superior Apple M1 machines, the nexus is broken and much of the Intel intellectual property is redundant. Apple could take a huge share of the PC market. Apple is not adverse to Windows. Windows programs will run on the new M1 machines, just not as quick as if the Windows ...
