Build The Best CB Antenna EVER! IMHO. The Half-Wave End-fed is an excellent antenna for CB, best used vertically. The 49:1 transformer is easy to make and affordable. This is a full size antenna with a low take-off angle great for skip and local communications. Wire length usually falls between 4.5 and 4.8m. Starting wire length in feet is 468 divided by the frequency in MHz. Check SWR and cut a little bit at a time. Do not use a metal box or expoxy. Hot glue is ok. Do not use another material than 43. The FT-140-43 can probably take up to 100W SSB, 70W AM/FM. For more power you… Read More

Testing My Mini 64:1 Half-Wave End-Fed Antenna Transformer. Field test of the Mini 64:1 HWEF transformer on 40m and 20m, with a surprising contact at the end! Who says you can’t use an FT-82-43? You don’t need three 240-size toroids stacked together to make contact, nor do you need hundreds of Watts. Save your money and build something that works well without breaking the bank and is light to carry in a backpack. Version Française: En traitement.

Icom IC 705 Ham Radio Raspberry Pi | Easy PAT Winlink Setup Hello Operators Todays video is a Ham Radio Raspberry Pi tutorial for the Icom IC-705 and eventually other radios. We will be using a new setup script call the Easy Mode setup for PAT Winlink running on a raspberry pi. This raspberry pi project will be the fastest and easiest version of PAT Winlink available, and perfect for someone just learning ham radio basics with a raspberry pi. Where traditional organisations like ARES have focused on EMCOMM (emergency communications) for disaster relief, regular people are increasing their skills and capabilities, by adopting asynchronous modes like Winlink and JS8Call,… Read More
