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**.

Chapter 25 hosts the Nebraska QSO Party which will take place in April

The Ontario QSO Party (OQP), an annual event, takes place on the third full weekend of April, specifically from 1800Z April 18 to 0300Z April 19, 2026, and 1200Z to 2000Z April 19, 2026. This **QSO party** encourages stations outside Ontario to contact as many Ontario amateur radio stations as possible, while Ontario stations work both in-province and worldwide. Key rule changes for 2026 include phone QSOs now counting equally with **CW** QSOs (2 points), the introduction of VE3RHQ as a bonus station, a 250m county line proximity definition, and a new Fixed County Line Category, alongside an adjustment of contest times. Established in 1998 by Bob Chandler VE3SRE, the OQP has been managed by Contest Club Ontario (CCO) since 2006. The event contributes to the State QSO Party Challenge, offering various award categories and maintaining records of past performance. Participants can submit activation plans, review Ontario multipliers, and access county maps. Final results and certificate winners are published, and a dedicated groups.io discussion group facilitates community interaction and support for logging software.

QCWW Chapter 120 amateur radio club

Recent researches seem to support the hypothesis that Sporadic E propagation could be connected to presence of thunderstorms.

As a ham radio club we get involved with contest, emergency response and services (CERT, RACE, ARES & etc), volunteering to organizations that needs our help (Community, Boys Scouts, Senior Citizens, & etc.), promoting and educating individuals of amateur radio operations (ARRL, FCC, Obtaining Licenses, Local Government, & etc), meeting new and interesting people around the world and beyond through many sources (VHF, UHF, HF, Computers, CW, D-Star, RTTY, & etc.), amateur radio is a great social skill, there is no age limit on who can get involved, and much more.

Accessing current operational statistics for a DXpedition is crucial for DXers planning their next contact. This Club Log page provides a detailed, real-time overview of the 3Y0J Bouvet Island operation, a highly sought-after DXCC entity. It presents a dynamic dashboard showing total QSOs, unique calls worked, and duplicate contacts, all updated as logs are uploaded from the remote location. Users can observe the expedition's progress and strategize their operating times. The interface features interactive charts and graphs, allowing operators to analyze the _3Y0J_ log data by band and mode, including CW, FT8, and SSB. A breakdown of QSOs by continent provides insight into propagation patterns and where the expedition has focused its efforts. The page also includes a map for checking real-time propagation conditions to Bouvet Island, which is invaluable for optimizing contact attempts. Further details include the first and last QSO times, total operating days, and the impact on users' DXCC totals, such as new bands, modes, or DXCC entities worked. This resource is a vital tool for the DX community, offering transparency and actionable intelligence for chasing one of the rarest entities on the air.

The European CW Association is an organization that hosts European CW CLUBS. Using the Association as a platform, member-clubs may exchange ideas and information, arrange various activities involving mutual participation, and generally co-operate for the benefit of amateur radio CW operation.

For my SOTA activities, i recently bought a QRP transceiver QRP SW-3B, which is a three-band QRP CW only for 40/30/20 m. So, i needed an antenna that would allow to use these 3 bands in SOTA portable activity. Already having some experience with the EFHW antenna, i decided to build one for 40/30/20m.

Modifying the Collins KWM-2 for Serious CW Operation, Make this old SSB workhorse perform like it should on CW.

This transmitter covers the 160, 80, 40 and 20 metre bands and provides both SSB and properly generated CW. The CW side of this transmitter is not compromised and produces excellent CW. On SSB the audio has been tailored to provide a rising response to 3 KHz, with a sharp drop above that frequency. There is RF speech clipping to both provide more "punch" and to limit the peak output.

The PJ5 St. Eustatius DXpedition, active from November 16 to November 30, 2019, involved operators SP6IXF and SP6EQZ. This operation targeted Saint Eustatius, designated as NA-145 for IOTA purposes, and focused on all HF bands using CW, SSB, and digital modes. The team logged approximately 23,000 QSOs during their deployment. QSLs for PJ5 contacts are managed via the operators' home callsigns, SP6IXF and SP6EQZ, with _LoTW_ confirmation available. The expedition also participated in the _CQ WW CW_ contest, contributing to the overall QSO count. Additional support came from individuals such as JA1BK, JA3DND, SP5BB, SP5GMM, SP9FMP, SQ7NSN, and KB7MM.

A home made CW keywer based on the W5UHX board.

Visualizes real-time amateur radio propagation spots using data from the PSK Reporter MQTT stream, providing immediate situational awareness for radio operators. The platform displays spots from various modes, including CW, WSPR, and JT65, in addition to the dominant FT8 digital protocol. FT8 Live focuses exclusively on live data streams, prioritizing current signal activity over historical archiving, which differentiates it from the official PSK Reporter map. A key feature is its integration with the Summits on the Air (SOTA) API, facilitating SOTA chasing by cross-referencing transmitting callsigns with SOTA alerts; a station is identified as an activator if the spot correlates with a scheduled alert within an eight-hour window. The user interface was developed by Arron (ZL1AN), with core data from Philip Gladstone (N1DQ), and stream delivery managed by Tom Stanton (M0LTE).
