SWR analysis of an Alpha-Delta DX-LB Plus antenna, configured as an inverted-V with the apex at 40 feet and ends at 15 feet, reveals specific performance characteristics across the HF spectrum. Measurements were conducted using a RigExpert AA54 antenna analyzer, scanning from 0.100 MHz to 54.000 MHz to capture full-range SWR plots. The antenna exhibits notably narrow bandwidths on 80 meters and 160 meters, attributed to its loading coils, necessitating precise tuning for optimal operation within these bands. Conversely, the Alpha-Delta DX-LB Plus demonstrates excellent SWR across the entire 40-meter band, indicating a broad resonance. Performance on 10 meters also shows favorable SWR, though tuning to a desired operating frequency is still recommended for peak efficiency. The article details the methodology and tools employed, building upon a previous "Part 1" analysis of a G5RV antenna, providing a comparative context for antenna evaluation. Practical experience with this multi-band antenna, particularly its loading coil design, highlights the challenges in achieving desired SWR across all bands without specific adjustments. The author's subsequent plans involve replacing the Alpha-Delta DX-LB Plus with a homebrewed 80-40-20-10m parallel **fan-dipole**, aiming for improved resonant characteristics.

Reports indicate the PA1RBZ DX Cluster, previously accessible via telnet at pa1rbz.dyndns.org on port 9000, is no longer operational. The QSL.net hosting platform displays a 404 error, indicating the specific page or file for the cluster's web interface or related information is missing. This service was designed to provide amateur radio operators with real-time DX spotting data, facilitating long-distance contacts across various bands. The cluster's primary function was to aggregate and disseminate DX spots, allowing users to monitor current propagation conditions and identify active stations. Such systems are crucial tools for DXers and contesters, enabling rapid response to new openings and rare DX entities. QSL.net, which hosts over 30,000 amateur radio websites, provides these services free of charge to hams, relying on user donations for operational continuity.

The Noantri WebCLX presents real-time DX spots, including frequency, DX callsign, country, and comments, facilitating active DXing and contesting. It operates as a web-based cluster, offering an alternative to traditional Telnet clusters for accessing spotting data. The interface displays current UTC, allowing operators to track propagation and activity across various amateur bands. This service is maintained by the _Noantri DX Group ARI Roma_, indicating its origin within the Italian amateur radio community. It supports the dynamic exchange of DX information, crucial for operators seeking new entities or participating in competitive events. Key features include the display of spots for modes like FT8, and it functions as a DXSpider-based system, providing a robust platform for **DX spotting** and **propagation analysis**.

CCAE Software Log provides a dedicated platform for amateur radio operators to manage their QSO records, offering functionalities beyond basic logging. This application supports various operational aspects, including contest participation and general DXing activities, catering to the needs of radio enthusiasts who utilize classic equipment such as Collins radios. The software integrates features for efficient data entry and retrieval, allowing users to maintain a detailed history of their contacts. It is designed to be intuitive for operators focused on collecting and preserving their radio communication logs. The program's development by the European Collins Collector Association (F6HOY) suggests a focus on reliability and specific utility for vintage radio enthusiasts. Its core function is to serve as a robust **logbook software**, facilitating organized record-keeping for ham radio operations.

A monoband delta loop antenna for the 7 MHz. This vertically polarized DX Antenna is a full wavelength sngle side antenna and has a total length of 42.3 meters (137,1 inch) Can be easily setup with a flag pole or fishing pole as center top mast.

The IZ3MEZ Web DX Cluster presents real-time amateur radio DX spots across 20 distinct frequency bands, spanning from **LF (2190m)** at 135.7 kHz up to **SHF (QO-100)** at 10499 MHz. It displays the DX callsign, frequency, DXCC entity, spotter callsign, and spotter DXCC entity, along with any accompanying comments. The cluster also lists various operating modes such as CW, RTTY, FT8, FT4, FT2, PSK, and SSTV, and supports special operating activities like QRP/P and specific award programs including IOTA, POTA, SOTA, WCA, and JOTA. The cluster's interface provides a dynamic feed of the latest 50 spots, continuously updated with precise timestamps. It offers direct **Telnet protocol** access for users preferring a command-line interface, with configuration instructions provided. The resource also integrates with other spotting networks like RBN and PSK Reporter, enhancing its utility for DXers and contesters seeking propagation information and activity monitoring across a broad spectrum of amateur radio frequencies.

First released around 1995 and significantly redesigned as QWTelnet 2, this software provides a dedicated interface for monitoring DX-Cluster traffic via Telnet. It integrates a **SOTAwatch parser** with configurable audio alerts, allowing operators to receive notifications for specific search patterns in DX-Cluster remarks without constant screen attention. The application also supports parsing for **GMAwatch (German Mountain Award)**, providing alerts for German Mountain Award activations. QWTelnet 2.4.0, released on 07-APR-2012, runs on Windows (tested on W7) and is distributed as a ZIP file containing the `qwtelnet.exe` executable. It does not require a formal installation process; users simply extract and run the program. The software can display DX information for single bands, integrate with the Reverse Beacon Network, and link to external web resources for DXCC and SOTA information. It also supports local reference files for IOTA, WFF, and RDA awards, which users must source and place in the `qwtelnet/files` directory. For IOTA data, users can convert `IOTA.CSV` from UCX-Log or `DX4WIN_IOTA.TXT` into `iota.csv`. WFF and RDA reference files are directly sourced from their respective websites.

IZ5CML, Enrico Giannerini, obtained his amateur radio license in 1998, achieving DXCC contacts with all entities over 18 years of activity. His station, located in Empoli, Tuscany, Italy, focuses on HF and 50 MHz operations, primarily using SSB, CW, and some RTTY. He emphasizes direct radio communication, preferring "human modes" over digital modes like FT8/4, which he views as detaching the operator from the signal. Enrico's operating interests include DXing, IOTA activations, and major HF contests, where he has participated both individually and with teams like IQ5LV and IO5O. Notable activations include Sao Miguel and Flores (CU8, EU-089) in the Azores in 2005, and Antiparos and Paros (EU-067) in Greece in 2006 and 2014. He also contributes to the Hamradioweb forum, promoting good operating practices and publishing the monthly "Dxschedule" for upcoming DX and contest activities. The website includes a blog with articles on DX, ionospheric propagation, and antennas, reflecting his long-standing passion for radio, sparked by the 1980s film "La Tenda Rossa" and years as an SWL.

The Utility DXers Forum (UDXF) provides a centralized platform for exchanging news and information concerning utility radio stations and signals operating within the 0 to 30 MHz spectrum. It specifically excludes broadcasting, pirate, and amateur radio transmissions, concentrating instead on a diverse array of other signals. The resource details the types of stations covered, including maritime coastal and ship stations, aeronautical ground and aircraft communications (voice, HFDL, Selcalls, Volmet), military operations, various beacons (NDB, driftnet, propagation, pirate, high-frequency), fax transmissions, numbers stations, diplomatic communications, clandestines, and other unusual signals. Further content addresses radar systems such as Over-the-Horizon, Ocean Wave, and CODAR, alongside ionosondes, chirpsounders, ALE-systems, Selcall-systems, and tone calls. Experimental stations and standard frequency and time stations are also within its scope. The forum also acknowledges utility radio-related amateur events like the International Lighthouse Weekend and Night of Nights, providing a broader context for listeners. The site offers sections for modes, hardware, software, a utility radio archive, digital BC & HF conditions, and a utility radio club archive, along with QSLs and pennants.
