We have received many OQRS requests. The answer will take a while. Another question was given with respect to the input of the worked callsign. That worked callsign can be entered under comment. But I will still look in all three log files for all QSOs requested.

We arrived early Monday morning back home.

Today is the last day of our DXpedition. Conditions on the low bands have been terrible all the time. Optimizing the antennas hasn't helped at all. We have had electrical power blackout all day long yesterday and we could operate only two hours. Not enough. We then got a very strong thunderstorm - the worst one we have experienced here so far. Another three hours QRX. Luckily no damages. We had a visit by Dammika, 4S7DF, his son 4S7FRL and 4S7RM at that time. The next night was as usual with three stations on the air and the low bands were another flop. We are going to begin dismounting the antennas today because we will be taken to the airport tomorrow morning at 5AM. It's another 100km to the airport in Columbo and we will take off at 0930 local.

New pictures added to the 4S7 pictures page.

Here is a report of the local conditions in 4S7. It's probably other than you expect, but conditons here are sluggish - even on the high bands. What we hear best are the cars driving past = QRM. The lower bands 40, 80 and 160m are even worse. Much QRN on 80m and 160m. Signals just reach S2 or S3. All skeds on 160m negative. We have no space for beverage antennas. We can't fight the QRN with other receiving antennas.

We have an L-antenna for 160m and an inverted vee dipole with a feed point at 20m height for 80m. One of the beam antennas is mounted on top of a water tank at 12m height. The other beam antenna in the garden at 9m height. At times North America is running well on the high bands however without a big number of QSOs. 20m is the best band for North America.

We will **not** activate IOTA AS-171.

First pictures are available now.

All antennas for all bands are built and working and we are optimizing them. Please enter your OQRS requests at the end of the DXpedition. Thanks.

The team has arrived in Sri Lanka on Monday rather late in darkness. There was a flight delay due to a broken airplane radio, hi. The 3 hour drive from the airport to our location was a bit of an adventure through the streets of Sri Lanka and it's traffic. It felt like a 1000km with all the traffic chaos.

We were so late that we had to go back to Colombo the next day (Tuesday) to get our licenses signed. It is required to pick up the licenses personally. Three call signs were issued that we need to use. Sigi, Georg and Frank lost one day while the others wered building the antennas.

The radios were set up in the evening - they all run. The electrical power supply however caused problems. That was another two hours of work. All stations are grounded now with additional groundings.

We worked the first night on 20, 17 and 80m logging the first 1700 QSOs. Work on the antennas will be continued today on Wednesday. Special thanks to Dammika, 4S7DF, for supporting us so well and to help us getting the licenses.
