CQ WPX SSB 2020

CQ WPX over … stn closed. Poor propagation, could not improve from last year. But 850 qso and 700k points in low power is also not bad. 🙂 4E1A

Last weekend I participated in the CQWW DX contest SSB part under the call sign 4E1A. Propagation was miserable on 40 m and 80 m; with my 100 W low power I was seldom heard by DX stations in EU or NA. On 20 m and 15 m propagation was acceptable, and I got even some openings on 10 m. Finally, I could exceed my points from 2018 and made 852 contacts with 62 DXCC entities and in 30 zones.

Contacts per band. Total 2287 QSO points and 191 Multipliers.

Raw score: 2287 QSOs x 191 multipliers = 436817 points.

FT-818 portable setup

Finished the setup of my portable station. All components are mounted together using maker beam profiles: FT-818, PA MX-P50M, ATM Z817, Solar charge controller and Computer interface.

CQWW WPX Contest 2018

The results for the CQWW WPX Contest 2018 are out for CW and SSB. I was able to achieve in both modes #1 in the Philippines for all bands, low power. In CW, first time ever, I became continental winner for Oceania.

Equipment: IC-718, 100W, Inv. Vee dipole for 40 and 80 and 3 el Spider beam for 15 m and 20 m. For 10 m I just matched the Spider beam with a matchbox.

cqww-wpx-ssb-2018 — Reached 1 Mio Pts. #3 in Oceania, #16 world wide, not too bad

cqww-pfx-cw-2018 — Didn’t manage 1 Mio Its, but still enough to become #1 in Oceania

Solar Power for portable Operations

Today I tested the first time my new solar power setup for portable operations. I am using a 60 W PowerFilm foldable solar panel and a 5 A MPPT charge controller for a LiFePo4 4S battery. The whole weight is 1600 g including the 5 m connection cable.

Hanging solar panel on the balcony – testing

It was cloudy day and the sun was most often covered by clouds. The panel is only exposed to 1/3 up to max. 1/2 to the full sunlight, if it is there.

Using a power analyzer to measure the incoming power and charge.

Using a power analyzer, the data show a 1.4 A peak current and 19 W peak power. I was able to charge 10 Wh in about 2 hours. Next time I will try to get the panel under full illumination in the sun and measure again.

The analyzer shows current, voltage and power and in addition peak values for current and power as well as total energy (power integrated over time) in Wh.

CQ WPX SSB Contest 2018

Over the weekend March 25th/25th I participated in the CQ WPX Contest SSB, category Single Operator, Non-assisted, Low Power. Although propagation was not favourable, I could make more than 1000 contacts and achieve more than 1 Mio points (raw score). Having fun!

The analysis of log data gives a good snapshot for the current propagation conditions from the Philippines.

CQ zones reached with time (local Philippines) and average frequency. Yellow: long path.

10 m band was open to Japan, Korea and China
