The 2018 International Friendship Exchange (INFEX) and DX Contest took place on Feb 17th, 2018. DX1ACE participated from the National High School Dasmariñas.
For the lower bands I am using a 40/80 m trap dipole. In order to become qrv on 30 m, I added a radiation coupled lambda/2 element for 30 m, using 10 cm spreader. After cutting the additional wire to the right length, the resonance on 30 m is exactly at 10.1 MHz. The additional element has no influence on the resonance for 40 and 80 m, but the impedance on 30 m is with 150 Ohm significant higher than 50 Ohm.
I just installed a VHF/UHF antenna in Tagaytay, and tried to find a list of relay stations. It is quite difficult at the moment, most of the information found in the web was outdated. Here a short list of repeaters, I can access.
My spider beam is up for one year now in Tagaytay. Unfortunately we have a lot of wind here, and the element wires of the beam started tangling.
I can only get it down in March or April, to check and bring some more tension to the lines and wires.
My first participation in this contest. Would have preferred the CW part, but we will not be here end of November. Decided to enter the classic, non-assisted, single operator class for 20 m band only.
Propagation conditions were not bad. 77 DXCC entities, 31 CQ zones and 411 contacts result in a raw score of 121 thousand. Quite satisfied with the result!
After replacement of my 80/40 m trap dipole with the G5RV antenna, I made some measurements. The antenna has a height of 12 m at the center, and is hanging as an inverted V with both ends still 4 to 5 meter above ground. The symmetric feeder line is connected via a 1:1 balun to 12.9 m 50 Ohm coaxial cable.
