Amateur Radio
News, gear notes, and on-air activity from the K8SCS shack and the wider ham community.
FT8 & Digital Modes
Weak-signal digital modes like FT8, FT4 and PSK31 — frequencies, tips, and decoding tools.
Space News
Rockets, satellites, and missions worth tracking — with links straight to NASA and mission updates.
Sunspot Levels
Current sunspot number and where we sit in Solar Cycle 25.
Space Weather
Solar flux, geomagnetic K-index, and aurora activity that shapes today's radio conditions.
Propagation
Band-by-band HF outlook so you know where to point your antenna tonight.
🧧 Space Weather Snapshot
NOAA Space Weather Prediction Center data — geomagnetic activity and aurora visibility.
Planetary K-Index
Geomagnetic activity over the last several days — high K-index means rougher HF conditions and possible aurora.
Aurora Forecast
Tonight's northern hemisphere aurora oval from NOAA SWPC.
📡 HF Band Conditions
General day/night propagation outlook by band — always check the live widget above for current conditions.
| Band | Daytime | Nighttime |
|---|---|---|
| 80m – 40m | Fair (regional) | Good (DX) |
| 30m – 20m | Good (DX) | Fair |
| 17m – 15m | Good in high solar flux | Poor |
| 12m – 10m | Variable, best near solar max | Poor |
| 6m | Sporadic-E openings possible | Rare |
💻 FT8 & Digital Modes
Hear nothing. Decode everything. FT8, FT4, and PSK31 pull real contacts out of pure noise.
FT8
15-second transmit cycles, great for weak-signal DX. Common dial freqs: 7.074, 14.074, 21.074, 28.074 MHz.
FT4
Faster cousin of FT8 (7.5s cycles) built for contesting and quicker QSOs.
PSK31 & RTTY
Classic keyboard-to-keyboard digital modes, still active on HF nets worldwide.
