Raymonde 2 (F5ZEQ v2)

Diagram of the relay The relay is now running on Svxlink on a Raspberry Pi 2 with a logic board by F8ASB and F5UII

The relay is by default in autonomous mode, it’s activated by a sound of 192.8Hz triggered by pressing your PTT (has to be programmed).

To connect to the RRF network, the combination of 96# in DTMF has to be transmitted.

Everytime the 96# command is received, the relay starts a timer of 10 minutes that increases of 5 minutes everytime it receives something. If the timer reaches 0, transmitting the 96# command is needed to stay on the RRF network. Otherwise, the relay goes back in local mode, meaning that the relay disconnects from the RRF network.

The reason for that is to have a local relay accessible only to the people living in the reach of the relay. Indeed, it’s pointless to transmit a conversation between locals to the whole francophonie. It’s also a way to save money on electrical consumption.

RFF Réseau des Répéteurs Francophones (French speaking relays network)

Before using the relay, it’s very important to read the instructions from the links below (in french) to avoid disrupting the RRF network which could have the consequences to break it.

Overview powered on (test frequency)


As you may know, keeping and maintaining a perfectly working relay 24 hours a day demands a considerable invesissment, because of surveillance, technical maintenance or even electricity cost.

As many Ham radio clubs, the club from Sartrouville suffers of the lack of new members and needs your help to keep working.

If you think that this relay is useful for you and want to get involved with its maintenance, we offer you the possibility to make us a donation to help maintaining the relay.

You can send us checks labelled to F5KCK at the following postal address: Radio Club de Sartrouville 78 Quai de Seine 78500 Sartrouville France.

Or you can directly meet us every friday evenings at 9:30pm at the same address.

Or even through internet using the link below:
