The collinear J-Pole, often known as the Super-J, does improve the behavior over a regular J-Pole. As many attest, there is an advantage when vertically combining 1/2 radiating sections to have a bit of separation between the half-wave end points. The Super-J has very little separation between the two half-wave radiators.

The Icom IC-7300 is a popular HF transceiver among amateur radio operators, known for its advanced features and ease of use. However, integrating it with software like Ham Radio Deluxe (HRD) can be challenging due to compatibility issues. This guide provides step-by-step instructions on how to configure the IC-7300 to work seamlessly with HRD 5.24, the last freeware version available. It covers the installation of necessary drivers, setting up virtual COM ports, and configuring audio settings for digital modes. To begin, users must download and install the Icom USB driver, which creates a virtual serial COM port for communication between the radio and the computer. The guide details how to check for this new port and adjust the CI-V address settings to ensure proper communication. It also explains how to set up the soundcard settings in HRD for digital modes, allowing operators to transmit and receive audio effectively. Following these instructions will enable IC-7300 owners to maximize their radio's capabilities with HRD.
