Determining the characteristic impedance (Z) of an unknown coaxial cable, a common challenge for many radio amateurs, can be resolved with a straightforward method. The impedance of a coaxial cable is derived from its inductance and capacitance, and importantly, these values are independent of the cable's length or the operating frequency. This means that measuring a random length of cable, such as 20 meters, provides sufficient data for calculation. The core of this technique involves an LC-meter to obtain the inductance (L) in microHenries (uH) and capacitance (C) in microFarads (uF). The impedance is then calculated using the formula Z = L/C. For instance, a measurement yielding L=1.2uH and C=450pF (0.00045 uF) results in an impedance of 51.6 Ohms, closely matching **RG-58** specifications. Similarly, a TV coaxial cable with L=1.8uH and C=320pF (0.00032 uF) calculates to 75 Ohms. While the accuracy of this method, depending on the LC-meter's tolerance, is approximately 10%, it proves sufficiently precise for practical determination of unknown coaxial cable impedance, as noted by Makis, SV1BSX, who credits Cliff, K7RR, for the formula's dissemination.

The Salvation Army Team Emergency Radio Network (SATERN) is a vital resource for amateur radio operators involved in emergency communications. This network facilitates the coordination of communication during disasters, ensuring that vital information can be relayed effectively. SATERN operates through a series of nets that connect operators across various regions, allowing for real-time updates and support during emergencies. Participation in SATERN not only enhances your skills as an amateur radio operator but also contributes to community resilience. Operators are trained to handle emergency traffic and provide assistance to those in need. By joining SATERN, you become part of a dedicated team that prioritizes safety and communication in times of crisis. The network encourages regular participation in drills and training sessions to ensure readiness when real emergencies arise.

The Texas Slow Net (TSN) operates daily at 7:45 PM local time on 3570 KHz, serving as a dedicated traffic handling training net within the National Traffic System. It specifically caters to operators aiming to enhance their **International Morse Code** skills and learn proper CW traffic net procedures. Each session incorporates a traffic handling lesson delivered as a radiogram to all participants, reinforcing practical application. The resource provides guidance on effective Morse Code learning, emphasizing sound recognition over visual dot/dash counting, suggesting characters be sent at 15 words per minute with adjusted spacing. It recommends listening to W1AW code practice transmissions, setting goals with ARRL's Code Proficiency Program qualifying runs, and regular participation in NTS traffic nets. The content also references the ARRL's Public Service Communications Manual, particularly Section 2, which details the **National Traffic System**.

This Field Day Vertical Antenna project is the result of many years of attending various field day sites and realizing that what was needed is a simple, easy to assemble vertical antenna. The design of this Field Day Antenna is not very novel and leverages ideas from Butternut verticals and ARRL publications. The one essential requirement was that the antenna can be raised by just one person. The design of this Field Day Antenna is an above ground mounted ground plane vertical.
