This is a very small vertical 160m antenna that fits in the loft of even my small house. It was built as a way of getting a signal out on 160m for local AM contacts, but the local noise level was far too high to allow it to be used at night for this purpose. However, on WSPR it did a pretty good job with WSPR spots from a very long way across Europe being received when running 2.5W out.

This article provides a detailed guide on how to build a no holes roof mount for ham radio antennas. The author shares their design that can hold 2 masts and offers tips on installation. The mount is versatile and can handle small 144 Mhz or 432 Mhz beams, as well as small verticals. With adjustable angles and spacing, the mount can be customized to fit different roof types. Additionally, the author suggests affordable options for obtaining Dish antenna mounts. Overall, this DIY project offers a cost-effective solution for ham radio operators looking to mount antennas on their roofs.

Despite the model limitations, such as a single TXRX antenna connector, the author shares a reversible modification involving a coax relay for enhanced functionality, demonstrating the transceiver's adaptability and customization potential.

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.
