I installed my radio this weekend. I can hear people but I can't seem to get a response back. I will want to try tonight after 8pm. What freq. will we be on?
You probably don't have your PL codes set correctly.
Yes. Look for the thing in your manual about "setting CTCSS tones" in the repeater section of the manual.
CTCSS stands for Continuous Tone Coded Squelch System which is a very low-frequency sub-audible tone superimposed on your FM carrier (transmission) in order to activate the repeater. This helps prevent false activation of the repeater by radar or spurious emissions. CTCSS involves 2 (TWO) actions:
1. setting the Tone Mode and
2. setting the Tone Frequency.
There are 3 basic settings used all the time:
1. OFF-- No tone encoded. Used for simplex and some repeaters that do not require a tone
2. T or TON or T-ENC-- Tone Encoded. That means the tone is sent with every transmission.
3. TSQ-- Tone Squelched-- This means that only if the station transmitting sends the tone out will your radio break squelch. If the guy on the other end isn't sending out the tone, your radio will sound the audio for a brief period (maybe 15-30 seconds) then the audio will be dropped or "squelched". This prevents other folks from interefering if they don't know the tone.
The repeaters we most commonly use and their tones:
145.145mHz 107.2 Hz tone (Colorado Repeater Assn)
145.310mHz 123.0 Hz tone (Colorado Connection-Linked state-wide)
146.805mHz 186.2 Hz tone (WA2YZT Repeater--IRLP node)
146.940mHz 103.5 Hz Tone (Rocky Mountain Radio League)
145.340mHz 103.5 Hz tone (Rocky Mountain Radio League--IRLP node)
Get them programmed, Scott, then we'll hear you!
