The amateur radio club serving Johnson County Tennessee and northeastern Tennessee and southwestern Virginia. Open to all licensed hams.

The _MFJ-915_ RF Isolator, rated for 1.8-30 MHz and 1500W PEP, exemplifies the product range available from The Ham Shop. The inventory includes various antenna support ropes, such as 3/16" _Dacron Polyester Rope_ in lengths from 100 to 1500 feet, alongside a selection of cables for _SignaLink USB_ sound card interfaces. Specific SignaLink cables are offered for radios like the Yaesu FT-847 (SLCAB847), Yaesu HTs (SLCABVXY), and the Elecraft K3 (SLCABHTY). Additionally, the shop provides modular jumper cables and modules, including the SLMOD8RY for Kenwood/Alinco 8-pin round mic jacks and the SLMOD8RI for Icom 8-pin round mic jacks. The product line supports diverse station configurations, encompassing antennas, coax, baluns, dummy loads, duplexers, insulators, microphones, power supplies, SWR meters, and watt meters.

Tubes are a dying technology. All modern transmitters, even high power ones, do work with transistors and other semiconductors. But many fondly remember their first homebrew transmitter and its hard to forget warm glow of a vacuum tube. The Station QRP website is especially for you to come into touch with tube technology. This site is all about handcrafted QRP AM tube transmitters.

A homemade oak plank drive-on mast holder proved functional but heavy and cumbersome. A lighter, compact commercial version from Amazon seemed ideal but couldn't fit the preferred Jackite pole. Costly alternatives, like a $100 mast holder from Three Mosquitoes Gear, were impractical. The solution came through DIY ingenuity: a piece of 2" PVC and hose clamps, repurposing materials already on hand. This simple, effective design perfectly accommodated the Jackite pole, demonstrating the power of resourceful problem-solving.

Demonstrates an **Arduino-based** solution for the Icom IC-7300 transceiver, specifically addressing the operational inconvenience of switching between a CW paddle and a straight key. The project leverages the IC-7300's **CI-V bus** (Computer Interface 5) to provide instant keyer type selection and two preset power levels, bypassing the rig's menu system which otherwise requires eight button presses. This implementation utilizes the 3.5mm CI-V connector, leaving the USB port free for CAT control and the internal soundcard, a critical design choice for integrated station setups. The system's utility is particularly evident for CW operators who frequently alternate between keying methods during contesting or general operating. The article details the hardware setup, including an Arduino Nano, a 3.5mm jack for CI-V, and pushbuttons for control. An update in 2023 expanded the project to incorporate an 8-button Nintendo controller, enhancing user interface flexibility and demonstrating the adaptability of the initial design for further customization and feature integration.
