An home made slim jim antenna for 2 meters band by VU2TQC

This tutorial provides step-by-step instructions for setting up the ICOM IC-7300 to work with WinLink and WinMor. The process begins with downloading the necessary USB driver from ICOM Japan, followed by configuring the radio settings through the menu. Key settings include selecting the correct output and data modes, as well as ensuring the USB serial function is properly set. Once the radio is connected to the PC via USB, the drivers will install automatically, allowing for seamless communication. After confirming the installation of the USB Audio CODEC and COM port, users are guided to download the RMS Client Software for WinLink. The tutorial emphasizes the importance of understanding the WinLink system and provides links to additional resources for setup. Finally, it details how to configure the WinMor modem settings, ensuring the ICOM IC-7300 is ready for effective digital communication. This guide is essential for operators looking to enhance their digital capabilities using the IC-7300.

This circuit stores a single morse code message as bits in an EPROM chip, the message is sent to a relay which can key a CW transmitter.

A simple 50 ohm dummy load to test transmitters. includes a simple RF diode detector to measure the peak voltage, and calculate the power

Demonstrates the operational status and reception reports for the SK6RUD/SA6RR QRPP beacons, which transmit on 478.9 kHz, 1995 kHz, 10.131 MHz, and 40.673 MHz. These beacons utilize extremely low power, with the 630-meter beacon operating at approximately 0.1 watt ERP into an L-antenna, showcasing the potential for long-distance contacts under favorable propagation conditions. The site details the specific frequencies and antenna types employed, such as a vertical at 500 kHz and a 1/4 vertical for higher bands. The resource compiles over 10,530 reception reports from amateur radio operators worldwide, logging details such as date, time, band, RST signal report, locator, distance, and receiver setup. Notable long-distance reports include a 500 kHz reception by AA1A-Dave from 5832 km in 2008 and a 10.133 MHz reception by ZL2FT-Jason from 17680 km in 2010, illustrating the global reach of these low-power transmissions. Each log entry provides specific equipment used by the reporting station, including transceivers like the Yaesu FT817, ICOM IC-7300, and various antenna configurations such as coaxial mag loops, inverted Ls, and end-fed wires. The primary objective of the SK6RUD beacons is to challenge conventional notions of power requirements for effective two-way communication, proving that contacts over significant distances are achievable with minimal output. The site also includes a submission form for new reception reports, fostering community engagement and continuous data collection on propagation phenomena across different bands. The detailed logs offer practical insights into real-world propagation characteristics and the efficacy of QRPP operations.
