This resource provides access to the 59+ software collection, specifically highlighting the **59+ CW** module. The software enables the generation of Morse code signals for transmission through a COM port to a transceiver, or for audio output via a computer speaker, facilitating both keying and listening practice. Users can customize various parameters, including CW speed, tone frequency, dash/dot ratios, and PTT line delay, alongside defining keyboard shortcuts for common QSO fields such as callsign, QTH, name, and RST. The collection also includes the 59+ Logbook, which operates smoothly on Windows XP according to testing notes, though the CW application experienced startup issues on the same OS. The software was originally designed for older Windows operating systems, specifically Windows 95, 98, ME, and 2000. It is noted that the original idealog.net site is no longer active, and development for the 59+ suite appears to be discontinued. Analyzer and converter modules within the collection require registration and do not function in trial mode.

A rotary trapped-dipole for 17 and 20 meters, as described by IZ7ATH, presents a practical solution for multi-band HF operation. The author, Talino, recounts his experience building this antenna for IK7ZCQ, detailing the evolution from an initial concept involving a grounded-driven element and gamma-match to a direct-fed, non-grounded design. His pragmatic approach, adapting available materials, is evident throughout the construction narrative, particularly with the use of eight tapered aluminum pipes for the driven element. Construction specifics include precise measurements for the aluminum tubing, with diameters ranging from 30 mm down to 16 mm, and a critical note on reducing tip thickness for weight optimization. The _traps_, initially a concern, are fabricated using 8 turns of RG58 coax on a 27 mm support, tuned to resonate at 18.1 MHz using a dip-meter. Talino emphasizes sealing the traps with RF glue and PVC tape to prevent water ingress, a crucial step for longevity. Field test results, conducted on a 10-meter pole in a clear garden environment, showed an SWR of 1.2:1 on 17 meters and 1.5:1 at 14.200 MHz. While SWR varied slightly when installed at Mario's QTH due to nearby objects, the antenna's performance remained commendable. The final half-dipole length is 46 cm for the 18 MHz tips, and the total weight is under 6 kg, with potential for further reduction.

RadioQTH's Vanity Calls service provides a utility for US amateur radio operators to locate available vanity callsigns, specifically focusing on the shortest possible options. The system filters through all potential callsigns within a user's license class and presents only those currently unused, with results weighted by either their actual character length or their equivalent length in _Morse code_. This approach assists hams in securing memorable and efficient callsigns for CW operation. The service also lists recently granted vanity callsigns, sorted by prefix, offering insight into current FCC assignments. It clarifies the common misconception that callsigns are granted on a first-come, first-served basis, explaining the random selection process for applications received on the same day. The platform updates frequently, providing current data on available 1x2, 2x1, 2x2, 1x3, and 2x3 callsign formats, which are highly sought after by _Extra Class_ and _Advanced Class_ licensees.

Accessing current contact information for amateur radio operators is crucial for QSLing, award tracking, and general communication within the Ham Radio community. This online tool provides a specialized callbook service, focusing exclusively on Croatian (9A) amateur radio operators who maintain active membership with the Hrvatski Radioamaterski Savez (HRS). It functions as a centralized database, allowing users to look up specific 9A call signs and retrieve associated information, primarily for verification purposes within the Croatian amateur radio scene. The utility of such a focused callbook lies in its direct relevance to local and regional operating activities, including contests, nets, and emergency communications within Croatia. While not a global callbook like QRZ.com or HamQTH, it serves a vital role for Croatian hams and those seeking to confirm contacts with 9A stations, ensuring data accuracy by linking entries directly to HRS membership status. This targeted approach streamlines the process of verifying Croatian amateur radio licenses and membership details.

Demonstrates practical solutions for reducing **Radio Frequency Interference (RFI)** in amateur radio operating environments, specifically addressing issues with PC monitors, receivers, and transceivers. The resource compiles advice from experienced operators regarding the selection and application of ferrite cores, including split cores and toroidal cores. It details specific material types like **43, 73, 75, and 77 ferrite**, outlining their effective frequency ranges for RFI suppression, such as 43 material for 30-400 MHz and 77 material for 2-30 MHz. The content provides part numbers for various ferrite products from manufacturers like Fair-Rite Products Corp, distributed by Amidon, and discusses their impedance characteristics across different HF bands. It compares the performance of various ferrite materials at frequencies like 4 MHz, noting that 75 material offers 27 ohms, 73 material 17 ohms, and 43 material just under 10 ohms. Additionally, it touches upon the use of bypass capacitors in conjunction with ferrites to create low-pass filters, emphasizing the importance of identifying common-mode versus differential-mode RFI paths for effective mitigation.

One specific challenge in the KazShack, operating Single Operator Two Radios (SO2R), involved sharing a K9AY receive antenna between two transceivers without direct RF connection or manual feedline swapping. The solution, detailed in this project, adapts the **W3LPL RX bandpass filter** design to split 160m and 80m signals, feeding them to separate radio inputs while maintaining isolation. This approach also addresses the issue of strong broadcast band interference from a nearby 50KW WPTF transmitter on 680kc. The construction utilizes T-50-3 toroids and NP0 ceramic capacitors, built in a "dead bug" style on copper clad board. Each band's filter coils are identical and resonated to the desired frequency using an MFJ-259 antenna analyzer. A single DPDT relay, controlled by a remote toggle switch mounted on an aluminum panel, facilitates quick band switching between radios, simplifying low-band operations. While some signal loss is noted, the expected lower noise levels from the receive antenna are anticipated to compensate, potentially reducing the need for constant volume adjustments during toggling between transmit and receive antennas.

This lookup service proves useful for local club organizers seeking to identify potential members within their service area or for hams planning local nets or events. The ability to export data with address details facilitates direct mailings for club newsletters or event announcements, while the browser view maintains privacy for casual lookups. The tool's design prioritizes ease of use, requiring minimal input to generate relevant local amateur radio contact information.

The _Italian VHF Beacons_ resource provides a detailed listing of active and QRT amateur radio beacons operating across VHF, UHF, and SHF bands within Italy. Each entry specifies the beacon's callsign (e.g., IQ1SP/B), operating frequency (e.g., 144.411 MHz), QTH locator (e.g., JN44VC), effective radiated power (ERP) in watts, and antenna configuration (e.g., Big Wheel, 4x Dipole, Yagi). This data is crucial for radio amateurs involved in propagation studies, equipment testing, and long-distance (DX) communication on these higher frequency bands, offering fixed signal sources for monitoring. This compilation, last updated in October 2005, serves as a historical snapshot of Italian beacon activity. For instance, it lists several 144 MHz beacons with ERPs ranging from **0.1W** to **10W**, and higher frequency beacons such as I8EMG/B on 1296.880 MHz and I3EME/B on 24192.132 MHz. The inclusion of QRT (Quiet Radio Teletype) status for many entries indicates the dynamic nature of beacon operations over time. Users can utilize this information to identify potential signal sources for band openings or to calibrate their receiving equipment against known transmissions.
