PRG offers a wide range of facilities.

Printed Circuit Board Manufacturing

PRG has facilities for producing high quality PCBs. We have an UV-light box for exposure of photo-PCBs, a professional etch bath sectioned in development and etch sections.

The etching bath has a heating element and an air pump for quicker etching. As corrosive we use Sodium Persulphate. The developer is a solution of Sodium Hydroxide (NaOH).

For the etched PCBs, we have small pillar drilling machines (0.3mm+) and a foot-pedal operated PCB drilling machine for standard (0.8mm) holes.

Photoresist circuit boards suitable for etching can be bought at our lab (size approx. 1/2 euro card, single or double sided).

Electronics Lab equipment

Our lab has the usual facilities, among others:

Microprocessor development

Development kits for Atmel AVR (STK-500) and Microchip PIC (PICkit 2), plus some older platforms (Hitachi 8 bit 68xx). UV eraser and EPROM programmer supporting standard 27C, 28F, 29F series devices plus some PROM based microcontrollers.


We have a nice assortment of components that are, for the most part, free to use for our members.

We offer standard logic ICs, 74xx-, 40xx-series, transistors and linear regulators (78/79xx, and variable). The usual assortment of passive components, resistors, capacitors, diodes (including LEDs), connectors, wire, etc.

Radio Equipment

We have a full radio installation. Anyone may listen, but you need a HAM license to broadcast.

We have two antennas on the roof of building 101, currently undergoing maintenance. There are antennas for the VHF and UHF bands, 0-30MHz. The UHF antenna is rotatable via remote control.
