Today tropo propagation was not as good as yesterday. In the early morning we did some Tropo + Meteorscatter test in FSK441 with PA3BIY and G4SWX. Nothing was heard. Best dx today on 2m CT1HZE. Just after dinner we made some EME qso's with the 9el yagi. It seems the ground gain lobs are at 9 and 18 degrees elevation.
We have planned to be qrv with EME on 2m at Moonrise 18/7 and 19/7. EME on 6m at moonrise is planned on 20/7. Today we also put up our 6m station and made the first qso's.

Wkd 144 MHz tropo: EA8RH, EA8CXN, CT1HZE. EME 144MHz: RX1AS, I2FAK, S52LM, G4SWX
Wkd 50 MHz: CT1HZE, F8DBF, EA8SG, EI3KD, CT/DL6IAK, EA8AQV, K1TOL, EA8DBM, FG4NN, VY2ZM.

Yesterday PE1ITR travelled to Cabo Verde with the 2m station and all antennes. All arrived savely. Yesterday on Tropo we received a FM Broadcast station from Cadiz on 97.4 MHz Today the 2m station was build up and at the start we had nice FT8 signals. We could mount the 2m antenna on the roof of our appartment. We saw the tropo was building up. Below the list of worked station in Tropo propagation. Highlight was working EA7JLM and EA7KR in SSB on 2m. Best DX CT7ABA 3180km!
Some words on the tropo propagation: We notice a very slow deep QSB on the signals. So have patience when working us. Also signal strenght can come up in a few seconds and stay for 1 minute or so before going into the noise.
The predictions are that tomorrow we will have also good tropo propagation. Then its going down. It will be good again Sunday.

Wkd 144 MHz tropo: EA8DBM, D41CV, EA7HLB, EA7JLM, EA7ITL, EA7KR, CT7ABA, EA7SL
Hrd 144 MHz tropo: EA1FBU, EA7LZ, EA7DUD sri NC.

To improve the AIS reception in a local shop a nice LPD antenna was bought. This worked and vessels at a distance of 800km could be seen on the map. We use AIS to detect tropo propagation.
12 and 13 Augustus there was tropo propagation to EA8 en CN and FM breadcast stations could be heard.

Today Frans D44LD and Gerard D44KZ, 2/3 of the crew, arrived save at our location in D4. The location seems good. We can put the antennas on the roof of the appartment with a clear view to the north. Gerard, our FM-DXer reports a low noise level on his FM receiver. We have internet. On sunday I will be departing to D4 with the 2 and 6m equipment. We have also 4m with us. If all go as planned we will be qrv on all bands from monday 15/7.

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.
