How to Enter an RX & TX Frequency and Calculate for a Repeater TX Offset

When using an amateur repeater, your will need to enter the Receive (RX) frequency as well as the correct transmit (TX) frequency.
You can refer to your local repeater list or directory for a list of frequencies and their correct offset frequency and Encode tone. As you will see below, each state will vary their local frequency band plans.
The 2-Meter band uses a - or +.600 KHz shift when transmitting. The UHF (70 cm) band uses - or + 5.000 MHz shift. For example, in Southern California on the UHF band they use a (-) shift. While in Northern California they use a (+) shift on the UHF.
Let's say we want to enter a repeater frequency of 145.300 with a (-)minus offset.
We now have to calculate the repeaters offset (TX) frequency. 2M repeaters are always + or -600 KHz. In most cases it's a minus (-) .600KHz
So we would take the receive frequency of 145.300 and subtract .600 KHz for the repeater shift. So our TX frequency would be 144.700
In the RX Frequency column enter [1 4 5 . 3 0 0]
In our TX Frequency column enter [1 4 4 . 7 0 0]
We have now entered the correct RX & TX frequency for this repeater.

How to Enter a Receive only Memory Channel

Quite often, we may want to enter a frequency into a memory channel for listening only (no TX). Let's say you want to enter a NOAA weather channel for receive only into memory channel #50.
Open the software and on the left side of the screen, Click on "Channel Message"
Scroll down to memory #50.
Type in the receive frequency [1 6 2 . 5 5 0] and hit enter.
Next click your mouse on the TX frequency box. Now press the delete key.
You should now see a Receive frequency of 162.550 and the TX frequency should now be blank.
Scroll across to the right side of the screen and in the "CH Name" box type in a name of "WX1"
You have now entered a receive weather channel into memory #50 and have added a name of "WX1" to label this memory.
Repeat the steps above as needed for add additional memory channels for receiving with no TX in that memory slot.
| Back | Continue to the Next Tutorial |

Selecting the correct Encode (transmit) Tone to Access the Repeater
In addition to entering the correct RX & TX frequencies above, most repeaters also require the use of a CTCSS or Encode tone.
After referring to your local frequency list click on the "Encode" column and select the correct (TX) tone for this repeater.
In most cases the "Decode" column should stay blank with OFF selected.
Using the information above you can now enter a receive, transmit frequencies, Encode tone and channel name for each memory channel.
Now go and have fun!
