PL tone for the 462.625 RAT repeater located on High Mt. Potosi is as shown in the chart above, 141.3.
and just to clarify for newbies, that chart shows the frequencies BACKWARD from the way a HAM states them.
When we talk about a HAM repeater (and GMRS is the same) we state the frequency the REPEATER transmits on, and the shift direction (shift is 600 KHz plus or minus for 2 meters, 5.0 MHz plus or minus for UHF HAM band, and ONLY PLUS 5.0 MHz for GMRS) and the PL tone.
So, if I asked you to meet me on a repeater you didn't have programmed, I would give you the information like this for that 462.625 RAT repeater: 462.625 (+) PL 141.3.
This indicates that your radio should SHIFT upward by 5 MHz when you push the PTT button, and it should transmit the subaudible PL tone of 141.3 Hz.
If programmed correctly, when you hit the PTT, your radio would transmit the 141.3 PL tone on 467.625 MHz which is the correct 5 MHz UP (Positive, plus, +) frequency from the repeaters TRANSMIT frequency of 462.625, and when you release the PTT, your radio will LISTEN on 462.625 MHz.
All GMRS repeaters are a full 5.0 MHz POSITIVE (+) shift UPWARD, that means that the repeater LISTENS on a frequency 5 MHz HIGHER than what it transmits on.
So, your radio needs to shift UPWARD (+) by 5 MHz when you press the transmit key.
That software lists the higher frequency as the TX (Transmit) frequency, which it is, but it is the transmit frequency for YOUR radio, not the repeater.
That RX (Receive) frequency shown is the frequency the repeater TRANSMITS on.
I have no idea why some of these software programs do it this way, in the radio world (HAM, commercial, etc. ) we always define what the REPEATER does, what frequency it TRANSMITS on, and the shift and the PL tone (if required, not all repeaters will make use of a PL tone if there is no other repeater near by on the same frequency or one very close to it, there is no need for the PL tone.
PL stands for Private Line, a Motorola® trademarked term.
A repeater LISTENS on one frequency, and if it is programmed with a RX (Receive) PL tone required, when it hears that subaudible tone on the carrier from your radio, then it instantly couples the output of its receiver to the input of its transmitter and activates the transmitter.
If it doesn't hear the PL tone it is programmed for, it doesn't do any of that.
Some repeaters will pass the PL tone on via their transmit frequency, so that you can have your radio programmed to receive multiple repeaters on the same frequency in the same geographic area, but you will only hear the one you select from the radio's memory that has the PL tone set up for RX as well as TX.
