You are not right! The sub-audible Tone (CTCSS) is used to transmit to the
repeater from your radio. The REPEATER always hears the tone on it's
Receive frequency that you are sending to it, and, this allows the
repeater to open to your radio transmissions. The tone opens the repeater
for each and every transmission when you push the PTT switch. The 145.47Mhz
machine uses a tone of 107.2 Hz on it's receive. You HEAR the repeater
600Hz up from the frequency that you that you actually transmit to the
repeater (144.870) on your transmit frequency only.. With a tone to the
repeater of 107.2 to open it. In this case you actually transmit to the
repeater on 144.870Mhz with a tone. Tone is used on transmit only. Tone
must be transmitted to the repeater for it to open and work. Tone is a way
of squelching a repeater from interference to and from other repeaters.
Now... the UHF repeater uses a different Tone. Check out the Arlington web
page or buy a repeater directory for other tones for other repeaters.!
Repeaters are listed in the directories by receive frequency. And, plus
or minus is used to tell you if your transmit frequency is above or below
the repeaters output frequency. Almost all repeaters in Virginia and the
country use CTCSS tones on the repeaters Receive frequency.
The webpage is absolutely correct: I have reprinted the Website extract

located in Arlington County and is open for general amateur use. It

unless it is a simplex test only or the repeater is down. 145.47Mhz is
where the repeater transmits only and no tone is required for you to

Dear Fellow AARC people
Attached is a page from our website.
My reading shows the subaudible tones on the listening channels.
I am right?
