Finally, I received my amateur license for the Philippines with the call sign 4E1ADW. Now trying to get a 2 letter suffix, like DU1KG or 4E1KG.
DU1 – Tagaytay – Jan 2017
During this visit I had more time to setup my station in Tagytay and test the antennas. I was very impressed by the performance of the spider beam and even the good propagation on the lower bands.

Retirement
Finally, after 30 years of service for Rohde & Schwarz, I had my last day in the company. A small “good bye” celebration with a surprise present.

Fiberglass Balcony Stealth Antenna for 40 m
In Singapore space is limited, and in our appartment it is difficult to setup any HF antenna. Our balcony is the only place where I have a space to mount something. Even there, officially nothing is allowed to extend out from the building.
I decided to setup a simple vertical, using a telescopic fiberglass pole, which I can pull out temporarly, when it is getting dark. The pole has a total length of 10 m, approx. 1 m (the lowest segment) safely mounted to the balcony railing and sidewall.

Weak Signal Digital Modes on HF-Bands
Many open source programs are available for Windows, OS-X and Linux, if you want to become active on the amateur radio HF bands using digital modes. Modern coding and modulation schemes allow for long distance contacts with low power.
Below you can download my presentation about PSK 31 (Phase shift keying) and JT-65/JT9 modes as presented in our monthly SARTS meeting August 2016 in Singapore.

DU1- Dasmariñas – Aug 2016
This time we stay longer than a week in our second home, and I set up a 12 m fibreglass pole with a G5RV multi-band dipole antenna for 40 m to 10 m. The pole is located at on corner of our area, the dipole endings are fixed at two other corners, so the antenna has a form of a 90 degree inverted vee.
Server down – repairing disk drive
After more than two years 24/7 the volume on my server degraded. One of the three hard disks crashed. Luckily there is some redundancy using Synology Hybrid Raid, and I am now trying to repair the volume. 5 TB of data at risk …
Once successful, will check the defect disk. Still should be under the 3-years warranty from WD.
