Holidaystation OE1DMB/OA4

For the first time I have been to Peru in 1999, at that time still as single. Then again 2002, now already with my engaged one. Both times without radio station, in 2004 I installed the first shortwave amateur radio station:




This is my holiday QTH in the province Barranca approx. 200km north of Lima, the capital of Peru. It is the house of my parents-in-law. During the holidays 2004 I put 13m wire over the building roof, attached it to a magnetic balun and koax cable without antennatuner to a SG-2020 and worked with 20W OK1DRQ in the proximity of Prague on 15m. Unfortunately this antenna was only matched on 17m and 15m, on other bands it had a very high VSWR.

In July 2005 I installed then a self dimensioned and selfmade T2FD antenna as inverted v with relatively small angle of inclination. Thus I had quite good matching on all shortwave bands. Although I had dimensioned the antenna for the bands 20m and up, the radiation was good only at 17m and above.





Since I assumed that folding the ends of the antenna in an angle of 90 degrees approx. 1m from each end, as you can see in the first photo of the antenna, could possibly have negative effect to the radiation characteristics on 20m, I tried to align the antenna as close as possible in one line, which changed however nothing in the radiation characteristics. Apparently it was simply too short although it was dimensioned for 20m according to Rothammels antenna book.

That is my equipment:
The FT-817 I had to repair just a few days before the beginning of the holidays, since I had blown the PA transistors of the FT-817 during experimenting with the PA FL-110. Due to this event I did not only repair the TRX with the new version of the PA, but modified also the FL-110, so that something like this will not happen again.
The station data:
TRX: Yaesu FT-817
PA: Yaesu FL-110
Power supply 12V/7Ah Bat.






The two newcomers at the station are my son Alexander (2 years 8 months) and my niece Angelina (1 year and 2 months).



This is a view from the balcony through the antenna toward homeland, which lies behind the two higher hills in picture center. One of my most ambitious goals was to make the connection into the homeland, which was succeeded with the QSO with Klaus OE4(50)KMU.



That is the front of my QSL card, which I use for OE1DMB/OA4. Who wants to know what I have worked, just goes to the logbook
