Based on the provided space weather forecast and the given parameters, with a Kp index of 3.00, A index of 8, solar flux of 148, solar wind speed of 530.7 km/s, and C1.4 X-ray flare, the current HF propagation conditions are moderately affected.
These conditions are close to favorable thresholds for HF propagation.
At 18.1575 MHz, propagation may be fair, while at 21.383 and 24.970 MHz, conditions are likely to be good for communication.
At 28.470 MHz, communication may also be possible, but reception could be slightly degraded compared to the lower frequencies due to the solar activity and geomagnetic conditions indicated in the forecast.
Overall, considering the current forecast and values, the bands that are most affected are likely 21.383 and 24.970 MHz, where HF propagation conditions are anticipated to be the most favorable for reliable communication.
