The Salt Spring Island Amateur Radio Club (SSIARC) operates the VE7RSI repeater on 147.320 MHz with a + offset. Set your FM radio for 88.5 Hz encode and decode. On April 25 2014, with the installation of a Yaesu DR-1, it became a a dual mode FM/C4FM repeater. It was replaced by a DR-1X on August 11 2016. It can seamlessly go back and forth between FM and Yaesu's digital C4FM (known as System Fusion) depending on what it hears.

We also operate the VE7RGP repeater on 444.550 MHz with a + offset. Set your FM radio for 103.5 Hz encode and decode. As of October 30, 2015, it has been a Yaesu DR-1X repeater. It too will seamlessly go back and forth between FM and digital C4FM.

System Fusion

System Fusion is Yaesu's "brand name" for digital C4FM FDMA. For almost a year, VE7RSI was the only System Fusion repeater in the vicinity. By mid-2015, there well over two dozen of them around us. VA7ANI was the next one operating in Ladysmith on 146.980 MHz - 141.3Hz. It has since been moved to Nanaimo. VE7RGP was converted over to a DR-1X on Oct 30 2015. There are over half a dozen of them in Victoria, one on Gabriola Island, one in Delta, one in Richmond, one in Burnaby, two in Squamish, one in Whistler, one in Sequim and one in Port Angeles.

C4FM Capable Radios

The following page shows all of the C4FM capable radios. The crop currently includes the FT1DR and FT2DR HTs, the latter with a greyscale touch screen, the FTM-100DR and the FTM-400DR, the latter with the super-deluxe colour touch screen, and the FT-991 and FT-991A HF rigs that includes 2M and 70 cm. With Canadian bandwith regulations, C4FM can be used on 10M and up. The improved FT-991A should be out later this year. The FT1XDR HT and FTM-400XDR mobile have improved GPS receivers. The most recent addition is the no-frills but budget-priced 2M-only FTM-3200DR mobile.

According to RepeaterBook there were 407 System Fusion repeaters around the world as of April 19 2015. By May 16, there were 471 listed. By July 1, there were 565. By August 1 it had grown to 635. By September 1, there were 680. By December 1, there were 886. By December 28, it had jumped up to 943. Just a few days into January of 2016, there were 951. January 31 2016 was a red-letter day... there were then 1,000 System Fusion repeaters on the air, and these numbers only includes the ones that have been submitted to RepeaterBook, so the real numbers could be much higher. Some reports indicate there could be as many as 1,000 to 3,000 ordered. We know now that it was at least 1,000. As of April 10, there 1134 repeaters listed. By the beginning of June, it was up to 1220. By the beginning of July, it was 1252. By August 1, it was 1286. By October 1, it was 1418. By January 1 2017, it 1536. These are "just a numbers" but they do indicate how quickly C4FM is catching on.

These two pages will list known C4FM repeaters in BC and in Washington state.


Developed by Yaesu, WIRES stands for "Wide-Coverage Internet Repeater Enhancement System" and WIRES-X is the latest generation. The interface that it uses is the HRI-200. It allows radios and repeaters to be connected world-wide. While it can be used in FM, using digital mode retains all of the slick features that C4FM users take for granted, such as crystal-clear audio, seeing the call sign and location of the station they are communicating with, and exchanging text messages and full-colour pictures. WIRES-x takes it a giant step further with world-wide linking. As well, voice messages can be recorded and left in a WIRES-X node and retrieved by other stations, as can text messages and pictures. Connections can be from node to node, or it can be to a "room" which is like a reflector that many nodes can connect to.

We don't yet have the funds to have a permanently connected WIRES-X node, but tests have successfully been conducted through both VE7RSI and VE7RGP to one... i.e. users have been able to go through the repeaters to a WIRES-X node and access other nodes around the world.

All of the C4FM radios can communicate through a WIRES-X node, but the newly released FTM-3200DR can't initiate or drop a connection.


The new VE7RSI repeater is up and running successfully, as is the new VE7RGP repeater, but many other changes are planned. While the club has some funds for the project, more are needed. Donations will be graciously accepted!

C4FM System Fusion Repeaters

VE7RSI was the first System Fusion repeater anywhere in the Vancouver/Victoria/Seattle area. However, as of May 9 2015, there were at least 10 of them operating nearby. By December of 2015, there were over 30 operational in between Seattle WA and Whistler BC. As of July 1 of 2016, there were 1252 System Fusion repeaters listed at By October, that number was up to 1418.
