VHF DXpedition to D4

From 14 july 2019 until 24 july 2019 we will be QRV from Cabo Verde (D4) on VHF. Our location will be maidenhead locator: HK85FD (IOTA: AF-005). This is on the east of the Island of Santiago near Pedra Badejo.

Our main dxpedition callsign is D44KZ. We will be active on 50MHz and 144MHz. Maybe also on 70MHz but that is pending. We are mainly a VHF Tropo, Meteorscatter and Ionospheric radio propagation DXpedition. Another main activity will be FM-DX listening on 88 - 108MHz.
Our station is EME capable so in between we are doing some moonbounce on 2m and 6m at moonrise and moonset when the moon is in our groundgain antennalobs. But moonbounce is not our main activity. And I note that the moon degradation is not in our favor.

This expedition is a major challenge because increased radio propagation conditions are needed to make QSO's. Of course we hope for that, but it is not certain whether those conditions will also be there during the period that we are QRV.
In general we have the following operation plan. For 2m we are open to skeds in whatever mode or propagation including experiments like TRAMS (tropo assisted meteorscatter. Info: link1, link2). Outside the skeds we will call CQ on 144.174 in FT8 in the 1st sequence. For 6m we watch or call CQ and see what happens. 2m and 6m can be active next to each other. We also keep an eye on the propagation conditions for Tropo or Es and will act accordingly. We have internet and will be on the KST chat. The Operation Schedule on this website will be updated regularly and is an indication what we are doing.

We will post more info, such as the operation schedule, and updates on this webpage.
