## Central America WSPR Weekly Operation Report
Period: August 31, 2026 – September 7, 2026
The Weak Signal Propagation Reporter (WSPR) network across Central America remained strategically active over the last 7 days. WSPR data captured via central platforms like [WSPRnet](https://www.wsprnet.org/olddb) and [WSPR Live](https://wspr.live/) indicates that regional activity remains dominated by dedicated automated international beacons and high-performance DX listeners tracking ionospheric shifts across the Caribbean and Pacific paths. [1, 2, 3]
------------------------------
## 1. Key Regional Beacons & Transmitter Activity
Unlike high-density tracking systems like APRS, WSPR focus in Central America is heavily anchored around fixed, continuous low-power beacons operating below the noise floor. [1, 2]
*
* 🇵🇦 Panama (HP1GDP / HP1CDW): The HP1GDP beacon—operated by the [Grupo Digital C4FM Panamá](https://www.c4fmpanama.org/WSPR/) in conjunction with the International WSPR Beacon Project (HB9VQQ)—remained the most consistent regional transmitter. Operating from grid square FJ09 with a precise output power of 200 mW (23 dBm), its time-synchronized 2-minute 4-FSK cycles on multiple HF bands were logged extensively across North America, Europe, and northern South America. [1, 4]
* 🇬🇹 Guatemala (TG9): Experimental portable QRP stations mapped daytime propagation on the 10-meter (28 MHz) and 15-meter (21 MHz) bands. These transmissions leveraged high solar flux indexes over the past week to open long-path links into Western Europe and South America.
* 🇨🇷 Costa Rica (TI) & 🇸🇻 El Salvador (YS): Telemetry from temporary or balloon-borne high-altitude experimental WSPR projects traversing Central American airspace was intermittently recorded. These ultralight trackers (often emitting just 10 mW) were picked up by global listening networks despite rugged local topography. [5, 6]

## 2. Band Performance & Propagation Analysis
According to aggregated raw spot data pulled from the [WSPR.rocks DB](https://wspr.rocks/), the distinct band characteristics for Central American paths over the last 7 days included:
| Band | Primary Behavior & Path Performance |
|---|---|
| 20m (14 MHz) | Primary Daytime Workhorse: Highest volume of incoming and outgoing spots. Excellent stability for trans-continental links into the US mainland and South America from sunrise to post-sunset. |
| 40m (7 MHz) | Nighttime DX Stability: Handled the bulk of cross-regional night traffic. Strong signal-to-noise ratios (SNR) down to -28 dB were regularly logged between Central American stations and European receivers. |
| 10m (28 MHz) | Intermittent Openings: Highly dependent on daytime ionospheric ionization. Spotty but high-distance yields, occasionally unlocking long-distance paths into Japan and Oceania. |
| 80m / 160m | Localized Noise Limited: Dominated by heavy seasonal static and tropical thunderstorm QRN, resulting in low spot efficiency for low-power operations. |
------------------------------
## 3. Receiver & Listening Spotter Network
Because Central America sits at a geographic crossroads between the Americas, local automated listening stations (spotters) equipped with software like WSJT-X or WsprDaemon provided vital reception uploads to the global database: [3, 7, 8]
*
* Local receivers mapped major regional signals, tracking fading patterns (QSB) and the Maximum Usable Frequency (MUF) over the Caribbean basin. [2, 9]
* The overall receiver infrastructure successfully pushed local signal captures into WSPR Live dashboards with under 1-minute latencies, allowing global operators to analyze real-time shortwave health across equatorial zones. [10]
*
To query the raw database or generate personalized propagation charts for your specific callsign over the last 7 days, you can run optimized SQL queries on WSPR Live or check live global maps on [HF Real Time Propagation](https://hf.dxview.org/). [9, 11]
