Some of the best amateur radio links we reviewed during the 2018.
RadioMasterList, a comprehensive receiver and transceiver directory. Performances and specifications for every radio set
An efficient 2 meter antenna disguised as a TV Satellite dish. This vertically polarized horizontal slot antenna, cut into the reflector of a TV dish, might be the ultimate stealth antenna.
Whatch at beacons transmitting in real time. This page contains a self refreshing table that displays every 10 seconds the current transmission schedule of the international beacon project. Tune your radio and check the beacon you are hearing.
The fan dipole antenna as an alternative to the paralled dipole antenna, to achieve a larger bandwidth and a better tuning by decreasing elenment influences.A project based on the W6HDG original concept.
6 element super duper moxon antenna for the 144 MHz, a modified HAARP Antenna projetc
A Progressve Communications Receiver by W7ZOI and K5IRK. First published in the November 1981 QST
Inline RF Power & VSWR Meter. A DIY meter 0 to 30 Watt with Average and Peak. Circuit Description, Arduino Nano software code and part list to DIY your own Digital SWR Meter
NVIS antennas, also known as Near Incident Vertical Skywave antennas have a high angle of radiation. Something on the order of 60 degrees, to straight up to 90 degrees. A portable, easy to setup and cheap nvis antenna project.
A guide to measuring SWR with different types of SWR Meters, the single needle and dual needle meters
An inexpensive spectrum analyzer for the radio amateur, with a respectable performance and a quite good dynamic range. Schematic and basic information on how spectrum analyzers works.
A six meter band 3 element yagi beam antenna project with shortened elements using coax cables with the outer ends stripped and the center conductor shorted in somewhat of a Bazooka antenna.
This project describe how to setup a Raspberry Pi Linux system with a few AX.25 packet radio applications already installed on.
A very efficient 80 meter Counterpoise antenna designed to reduce ground losses from inadequate radial systems beneath inverted L antennas, a project by DM2GM and DM4IM based on the original K2AV antenna concept.
A helically wound vertical antenna experiment. 14 meter of wire wounded on a 8 meter fishing pole with 4 elevated radials
Dimensions and EZNEC plots for a 2 Element 30 meter Yagi antenna with 28 Ohm featuring 4.3 dBd Gain and a 16dB F/B with a good bandwidth.
Why build antennas out of copper and not aluminum or stainless steel. Selecting the best metals for antennas evaluating the conductivity factor.
Consider installing a stealth vertical loop antenna if you live in a place with no antenna restrictions. Full wave loop wire antennas allow you to be on the air without installing evidente external aerials.
This simple project, based on the orginal CobWebb-Antenna model, is about an horizontally polarized, omi-directional antenna for the six meter band.
The antenna in this project is a modification of the techniques used to design a multiband fan type dipole with little or no tuning involved having a total space of 105 feet
Photo construction manual of a portable antenna made with two heavy duty whips by buddipole. In this article has been implemented a 50 MHz portable dipole.
This Antenna project is a bit more complex than other omni antennas for satellite use, but it is much easier and cheaper than a standard tower mounted circular polarized azimuth and elevation rotating beam system.
A Small Transmitting Loop Antenna for 14MHz and 21MHz, an antenna you might consider if you have limited space, Based on material originally published in Amateur Radio, November 1991
A PDF File to download and print, with a table of all menu options with values, default settings, description and a quick reference guide of the front panel menus
A beginners guide to DMR. This web site cover all aspects of DMR and is a valuable resource for those who want to get started with DMR.
Extension to an existing fan dipole originally modeled for 40 20 and 6 meters. This modification will add 80 15 and 10 meter bands.
Camping with Ham Radio is fun, but twice as complicated as just camping. There are two lists of things not to forget, the camping stuff and the radio stuff.
A simple receiver front end protection ciruit idea to protect your receiver when it is not in use
This article describes a project of asymmetrical hatted vertical dipole, a portable antenna that can be used for field day operations, sota, campings or even for fixed installations. This is a freestanding 20-10m antenna that is really easy to build, easy to tune and relatively easy to carry.
The list represented in this article is just a selection of best amateur radio links we have reviewed and added to our links directory.
