ESRAC stands for Eindhovense Students Radio Amateur Club. The intention was to involve more and more (non) technical students and teachers from Fontys University of Applied Sciences and Eindhoven University of Technology (TU/e) to work and to participate in this radio amateur club. A pro-active club! Radio-active 🙂

Free membership for students

Fontys and TU/e students can join the Eindhoven Student Radio Amateur Club (ESRAC) for free.

The amateur radio station Pi5FTS is (still) located in the Electrical and Electronic Engineering (Fontys) department in Eindhoven. In 2013 the shack was build in a small space in a lecture room, which was and is not an ideal situation but we got some space! The general idea was to start small and get an optimal shack version 2.0 in 2020 in the new building (read here) with new radio equipment.

However, in the new location (Rondom) there is no room any-more for a radio shack. Since March 2019 the board members from SV. Innovum, Sound Engineering, Salve Mundi and some lecturers from Engineering and ICT are now looking for other options. We will update this progress on this website.

Amateur Radio Station Pi5FTS operates in the Electrical Engineering Building, R1 0.180 and is located on the Fontys University of Applied Sciences Eindhoven, the Netherlands. Pi5FTS is available for the use by the ESRAC members. In addition, the club frequently operating events, as well as educational activities for local schools and scouting groups.

Station Equipment
The station is currently active on the HF bands using the FLEX6500 on SSB, CW, RTTY, and PSK31, 2m/70cm (on FM, DMR, DStar) and have satellite capabilities on 2m and 70cm. The station is well-equipped multiple Software defined transceivers. The Pi5FTS “shack” also has a complete bench of electronic test equipment and assembly tools to support the club’s many ongoing technical projects

Pi5FTS features a full suite of high performance antennas covering 3.5 MHz to 1.2 GHz. The shortwave bands from 7 MHz to 30 MHz, as well as the 50 MHz band are covered by our 4-element tuneable Yagi-Uda at 105 ft above ground level. Wire dipole antennas cover 3.5 MHz to 7 MHz, long-boom Yagis for 144 MHz and 430 MHz top the main W8UM tower, while a Discone at 90 ft covers 30 MHz to 1.2 GHz. The club strives to constantly improve our antenna system and lots of room exists for club members to implement their own antenna designs on our tower and rooftop “antenna farm”.

A dedicated satellite antenna tower supports circularly polarized Yagis for 144 MHz and 430 MHz mounted on an elevation-azimuth positioner. Future plans include the installation of 2.4 GHz and higher frequency reflector antennas and associated electronics to support our Earth-space communications links.
