VOACAP DX Charts - Helping DXpeditions succeed, helping amateurs connect.
Happy Holidays everyone & Good DX!
I am thrilled to introduce #VOACAP Online for SWL – a free-of-charge dedicated shortwave propagation prediction service designed specifically for shortwave listeners (SWL). Accessible at www.voacap.com/swl/, this powerful online tool brings professional-grade propagation analysis to your fingertips.
Notice #VOACAP Online users: In recent Chrome/Edge browser versions, SVG rendering of thin lines has regressed. VOACAP Online’s propagation wheels may look broken or jagged. Firefox/Safari display them correctly - use those for best results until Chromium fixes this.
Two exciting new DXpeditions have just been added to the #VOACAP DX Charts:
* S21SDX – Bangladesh (Nov 11–17, 2025)
* J38W – Grenada (Nov 23 – Dec 3, 2025)
Check them out at voacap.com/dx/ . Good DX and may the bands be open!
Major update to my #VOACAP tools: github.com/OH6BG/VOACAP...
- run_p2p_matrix.py: safer, cleaner point-to-point predictions
- plot_maps.py: generates VOACAP coverage maps, now fully compatible with the HamCAP DX Charts framework I just updated yesterday. Demo: www.voacap.com/dx/cy0s/hamc...
New release: HamCAP Maps → github.com/OH6BG/HamCAP... . A lightweight client-side viewer for #VOACAP coverage maps made with HamCAP: multi‑band, 3 time slots, lazy‑loading, LRU cache, keyboard access, theme toggle & zoom‑in‑tab. See 3Y0K Bouvet, Feb 2026 demo → www.voacap.com/dx/3y0k/hamc...
A lot of backend refactoring done at #VOACAP online (www.voacap.com/hf) to make the services more robust. Added new visual cues for ITU Wheel predictions: progress is now shown directly in the button w/ light red background color. Each run takes about 5 seconds, so a little patience is appreciated.
Two upcoming operations now have their own dedicated propagation prediction sites at #VOACAP DX Charts (voacap.com/dx/), including VOACAP and ITURHFProp forecasts plus detailed sunrise/sunset times:
* 5K0UA – San Andres Island (Oct 20–30, 2025)
* FW5K – Wallis and Futuna (Oct 20 – Nov 7, 2025)
Opened a special propagation site for 5R8TT & 5R8XX Madagascar (Oct 29–Nov 12, 2025), now on the #VOACAP DX Charts list (voacap.com/dx/5r8tt/). Features VOACAP & ITURHFProp predictions, sunrise/sunset data, and an azimuthal equidistant map. Good DX!
Updated #VOACAP DX Charts with propagation predictions for 9L8MD Sierra Leone (Oct 30–Nov 10, 2025). As we heard, 3C2MD Equatorial Guinea was cancelled. But now a special site with VOACAP & ITURHFProp data + sunrise/sunset times is live for 9L8MD: voacap.com/dx/9l8md/ — Good DX!

DX Summit Update at dxsummit.fi! HF propagation predictions now powered by ITURHFProp via #VOACAP Online, showing Basic Circuit Reliability for hopefully more accurate results — especially on low bands and on long-path circuits.
Give it a try and see the difference!
1/2 -- Exciting update on #VOACAP Online! Now featuring two Propagation Wheels: CAP Wheel (VOACAP’s REL value) & ITUR Wheel (ITURHFProp’s BCR value). Both measure circuit reliability but use different methods—compare them for better low-band predictions from ITURHFProp! Try it now: voacap.com/hf/
Time for the summary sheet for vertical antennas at #VOACAP Online!
Ground quality matters—seawater boosts the take-off angles & gain of the verticals. Horizontal antennas (Yagis/dipoles) see little benefit.
This sheet shows take-off angles only, not gain. Patterns can’t be compared for gain.
