The weekly summary of APRS (Automatic Packet Reporting System) activity in Central America, corresponding to the week of August 24 to 30, 2026, shows a consolidation in the use of hybrid gateways (RF to the Internet) and a remarkable expansion of the LoRa subnet in urban areas. 
At the regional level, the activity was structured through two different trunk frequencies and a constant volume of telemetry and beacon exchange. 
📊 Frequency and Traffic Distribution by Zone
Unlike North America (which unifies everything at 144.390 MHz), Central America operates in a segmented manner according to its regulations and technical influences: 

    South Zone (Panama): All VHF activity was concentrated on the official frequency of 144.930 MHz. It recorded the largest traffic of fixed and mobile ground position frames in the region. 
    North and Central Zone (Costa Rica, Guatemala, Honduras, El Salvador): They operated mostly on the frequency of 144.390 MHz, aligned with the IARU Region 2 standard (North America and the Caribbean). 
    Emerging Subnet (LoRa APRS): The 433 MHz (UHF) band experienced a 15¢ncrease in weekly beacons in the Costa Rica and Panama nodes, powered by low-cost microcontrollers (TTGO T-Beam type).

📡 Activity Highlighted by Countries (Weekly Metrics)
🇵🇦 Panama (High Density in Data Channels)

    Infrastructure: The HP1CDW-4 (Cerro Ancon) and HP1DBK-10 (Tocumen) trunk nodes operated at 100Üvailability, capturing traffic from the Pacific coast. 
    Floating Telemetry: The LoRa HP2PCN-15 (Gatun Locks) node served as the most efficient digital repeater in the Atlantic sector, reporting stable voltage variations (3.83V to 3.87V) in its autonomous solar power systems. 

🇨🇷 Costa Rica (Automated Meteorological Network)

    Base Stations: The Radio Club of Costa Rica maintained active monitoring through its reference node TI0RC in San José, serving as a link for the perimeter iGates.
    Climatological Data: Automatic weather stations (WX) integrated into the APRS network doubled their transmissions of wind, humidity and barometric pressure frames due to Pacific climate instability, injecting data directly into aprs.fi servers. 

🇬🇹 Guatemala and 🇭🇳 Honduras (Tactical Tracking and Messaging)

    Tactical Use: Stations coordinated by the Guatemalan Amateur Radio Club (CRAG) maintained active position beacons in perimeters close to areas vulnerable to rain.
    Routing Used: 88¨f packets in this zone used the standard WIDE2-2 path, minimizing unnecessary duplication of frames in mountainous areas. 

📉 Regional Network Metrics (Consolidated Weekly)
Network Metric Percentage / Average Network Status
Successful Path Efficiency 91.4¨f frames injected to APRS-IS Excellent interconnection
Key Package Type 68©osition / 22œlimate (WX) / 10­elemetry Network oriented to tracking
Message Exchange (SMS) Average 45 daily messages via RF-IS Moderate messaging
