The Broadcast Employees Amateur Radio Society, Inc. (BEARS) operates an extensive network of **VHF and UHF repeaters** across New York, the Hudson Valley, Long Island, and New Jersey, accessible to all licensed amateur radio operators. This resource details the club's structure as a 501c3 tax-exempt non-profit, emphasizing its role in providing ham radio training, testing, and critical communications support to various public and private emergency response agencies. Key repeaters include W2ABC/RPT on 147.27 MHz with a 141.3 PL tone, serving as a central point for club activities and broader network access. BEARS is also a founding member of the **Disney Amateur Radio Interconnect (DARI)**, a consortium of open, linked VHF and UHF repeaters spanning major metropolitan areas such as Philadelphia, Baltimore/Washington DC, Orlando, Bristol, Los Angeles, and Boston. This interconnected system facilitates wide-area communication for members and supports emergency preparedness efforts across multiple regions. The club's focus extends beyond Disney employees, welcoming aspiring and current hams from outside the company to participate in its activities and utilize its robust repeater infrastructure.

_HamDXMap_ provides propagation analysis and operational aids, integrating real-time data with historical logging capabilities. The platform displays Maximum Usable Frequency (MUF) and foF2 response curves, with a horizontal bar indicating live VFO frequency from _Win-Test_ via Gateway software. It supports _VOACAP_ 24-hour propagation predictions for Short Path (SP) and Long Path (LP) tabs, factoring in monthly smoothed sunspot numbers. The minimum bounce altitude for propagation calculations is **50 km**. The tool features a _ClubLog_-sourced DXCC Most Wanted ranking in voice, telegraphy, and digital categories, displayed in callsign pop-ups and DXpedition lists. Users can import contest logs in ADIF format, visualizing QSOs on the map with adjustable line and point parameters. A playback function allows contest replay at speeds from **1x to 100x**. An _IOTA_ (Islands on the Air) layer displays island group definitions and confirmation percentages, indicating RSGB activation evidence requirements. _HamDXMap_ integrates over 1100 online SDR receivers from three networks, updated daily, with access links and a favorites function. It tracks current and future DXpeditions planned over the next 45 days, sourced from _The Daily DX_, _DX 425 News_, _DX World_, _Les Nouvelles DX_, and _NG3K_. Real-time weather information, including temperature, wind, and pressure, is displayed in DXCC country and RX/TX position pop-ups.
