The addition of a Continuous Tone Coded Squelch System (CTCSS) code(s) has recently been implemented in a number of local repeaters. CTCSS uses a sub-audible tone transmitted on the signal of the transmitter trying to access the repeater.
So why would we want to do this? CTCSS is used by repeater systems to prevent noise or interference from causing the repeater to squawk obnoxiously and by receivers as an extra measure of squelch. In other words, CTCSS codes will reduce noise and interference, as well as allowing for weaker signals to be heard on these repeaters. As well, the use of CTCSS tones is almost universally used to access amateur radio repeaters.
Here is the list of repeaters that now require a CTCSS code:
The VE9TCF/R Fundy repeater (145.170) will be changed to these CTCSS codes as soon as Cam VE9CAM and Jeff VE9JJS can go to the repeater site in Fundy National Park.
Now is the time to update your VHF/UHF memories by adding the CTCSS code. According to Cam, VE9CAM, CTCS codes do make a big difference!
