01
VOACAP Propagation Prediction
Point-to-point HF reliability, hour by hour, on the NTIA/ITS VOACAP engine — the US government standard model for skywave propagation.
02
Solar & Space Weather
Solar flux, sunspot number and the A and K indices — the inputs a propagation run depends on, from NOAA’s Space Weather Prediction Center.
03
SPEED Restricted
Terrain-aware RF link planning: path profiles and line-of-sight analysis over elevation data, for laying out circuits before you put antennas up.
04
VLSM Subnet Planner
Plans IPv4 and IPv6 subnets from the block you were issued, around whatever is already in use — and says when the block is too small and what to ask for instead.
05
Radio Troubleshooting
What to check when a radio will not talk, in the order that rules out the most causes fastest, and why each check matters. General guidance, not a substitute for the equipment’s manual.
