M7ENP Adventures & Experiments

The world of ham radio is filled with fascinating people, ideas, and projects. One such project that caught my attention is the "continuously loaded, helically wound vertical antenna" designed by Bev AH6NF (YL). In this article, we will analyze the design, materials, and steps to build this antenna, and then we'll give it a try ourselves to see how it performs. Design The design of this antenna is simple yet effective. It is a vertical antenna that is helically wound with a 91cm stinger. The stinger can be folded along the 122cm mast for easy storage. The antenna is continuously loaded, which means that it is designed to operate on multiple bands without the need for an antenna tuner. Materials The materials needed to build this antenna are readily available and affordable. The list includes: 1.22 meters of 1.27 cm white PVC water pipe 9.14 meters of 1.63 mm² insulated electrical house wiring 2.38 mm diameter brass brazing rod, 91 cm long Miscellaneous junkbox stuff Numbe

This is a project that looks very interesting, it's a dual vfo SSB transceiver published by Pete Juliano, radio ham N6QW and co-host of the popular podcast Solder smoke. so let's get started the first job is to read all the documentation and then read it again. After reading the documentation and printing the documents I emailed Pete and asked if I could get a copy of the Arduino sketch for this project, Pete sent me the sketch as requested. Fantastic thanks, Pete. OK, next job is to get all the parts together,  all parts are all available and as a bonus, we managed to get the mixers ADE-1 supplied by mini circuits in NewYork and mini circuits supplied them free of charge as a sample. sofar so good, ok so let's get a bill of materials together. To do this we used my favourite cad and PCB design tools, Using Easy EDA we started to sketch up the schematics and create a list of part, why redraw the schematics? we hear you ask, we did this so at a later date if everything works
