TONE vs. CTCSS vs. DSC


 

Hi there.
Sorry if this question seems simple and novice, bit I really need help understanding why Ft60 makes such differentiations.
I get the last two tones perfectly. But the TONE option throws me off..... I have no idea why it's there and what to do with it and WHEN.....

FW #1, is the menu, of course.

Thank in advance

Tone means it produces a pl tone when transmitting.

CTCSS means it produces tone AND takes a tone to open squelch.

DCS is a digital method of opening/closing squelch. Same purpose as the other two, just a different method.

PL (Private Line)?
CTCSS (continuous Tone-Coded Squelch)
DCS is Digital Code Squelch.
Many repeater directories use PL to mean CTCSS and DPL to mean DCS

They are simply two different ways to cause functions to happen at the remote site.
Many repeaters only use these two different tone methods to open up the repeaters receiver to relay your message.
Some use DCS on both transmit and receive, meaning you have program the tone going both ways through your radio.

Hope this helps..

You NEVER have to use DCS or CTCSS (PL) on receive. These repeaters might put out the tones, but you only have to use them if you are getting interference from other repeaters or electrical devices. ?Anybody can receive without the tones, so remember, just because the repeater might transmit them and you use them, your conversations are not private.

>> ... you never have to use DCS/CTCSS on receive ...

Only time I do is at events on simplex ...

Out here in Southern CA, not a single one of my rigs is programed "closed tone" for any?
of the repeaters. Two cases-in-point immediately come to mind.

We have two high-level machines that "bump into" other legal machines 60+ miles away. I mean, you can sometimes hear the "other" machines break squelch on the "local" machine. If I were to "lock up" onto my local repeater's tone, I just might interfere with those other repeaters. Who knows if someone was calling in a traffic incident ... or just chit-chatting. But it is every ham's responsibility to NOT interfere with others' legal transmissions. Lock up the tone on those machines, and I would never know when I was interfering with someone else.
