Welcome to my PA7LIM website! I’m David and I live in Utrecht with my girlfriend and beautiful daughter.

My occupation is Linux/Network/Cloud consultant at a company in The Netherlands. Certified in VCP, CCNP datacenter, CCNP routing/switching,  CCDP, LPI 1&II, RHCE (almost RHCA).

In my private life I like to play/listen music, play golf, drive motor.

In May 2013 I passed my Novice HAM license ( PD7L ) and 4 months later I bought my icom ID-51E and red dongle. The combination of HAM radio and programming brought me to the idea to write an android application called ircDDB remote.

In March 2015 I passed my Full license ( thanks to PA3GER and PA3FMN) . My new call is now PA7LIM.

In the summer of 2015 I started a new project. I tried to make a DSTAR hotspot/dongle on an Android phone. ( thanks YouTube how to make an Android app )
I received an AMBE3000 board from Guus PE1PLM en started to build the software. After a few weeks of wiresharking (network sniffer) the G4KLX software, I was able to make my first QSO from an Android phone. Then I started to make a hotspot with the DVMEGA dual band transceiver, so I could make a QSO from a ICOM transceiver. In 2016 I got in touch with Rudy PD0RZY, who helped me to understand the Brandmeister DMR part. In the meanwhile Guus PE1PLM made the DVMEGA DMR ready and Ruud PE1MSZ made the Bluetooth board. In February 2016 I had a working DSTAR and DMR hotspot. End of 2016 I started with a new programming language and made BlueDV for Windows and Linux.

Begin of 2017 I started iOS programming and made BlueDV for iOS. Took me a lot of time to make this because of issues with BLE timing.

In Jun 2017 I started coding with the AMBE3000 chip.

August 2017, looking for a new adventure.
