The 2018 International Friendship Exchange (INFEX) and DX Contest took place on Feb 17th, 2018. DX1ACE participated from the National High School Dasmariñas.

OCF dipole for 40, 20 and 15 m on a 12 m fiberglass pole and commercial v-shaped multi band dipole

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.

VSWR_30m — 10.1 MHz Impedance (141 – j34) Ohm – VSWR 3

40m_VSWR — 7.1 MHz Impedance (40 + j1) Ohm – VSWR 1.24

80m_VSWR — 3.6 MHz Impedance (27 – j5) Ohm – VSWR 1.9

VHF/UHF Repeater in District 1 Philippines

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 It is quite difficult at the moment, most of the information found in the web was outdated.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.

Bread Baking Gallery

I am baking my own bread for years already, but in the past I did it mainly with a bread baking machine using commercial yeast. In September 2017 I started my own sourdough, and over the last couple of months the breads became better and tastier. End of November 2017 I bought a kitchen machine, so that I can knead the dough with the machine. Important for a good bread is a slow fermentation of the dough. Usually it takes at least 16 to 24 hours from the first dough to the final loaf.
