Tried listening to VU7T DXpedition on 15m!

VU7T Lakshadweep Islands Dxpedition 2025 is active from Agatti island using vertical antennas for 40-10m and on QO-100, in spite of the inclement weather due to early onset monsoon. Could hear the callers on 21MHz, but not the DXpedition, may be because I am within the first hop skip zone as the distance is only around 234 km! I am likely to get them only if they are seen on 40m.
