Output and Input?

[jerrytheyounger]

When you are looking at a repeater on the list and and it says output with one frequency and input with another, what does this mean. Which frequency is your radio supposed to be set to? Sorry for the newbie question, but I'm confused.

The output is the frequency that the repeater transmits on; the same frequency that you listen to. The input frequency is the frequency that the repeater listens on; the same frequency that you transmit on.

 

In the GMRS world, when using repeaters, the repeaters always listen to frequencies in the 467 MHz band, and always transmit on frequencies in the 462 MHz band. Convention has it that there is always 5 MHz difference between the transmit and receive frequencies.

 

Hope this helps.

So if I got this right, if the number after output is say 462. that is the frequency my radio should be tuned to? I'm sorry I'm so dense. Science is my weakness.

Yes and No, Yes, you should be tuned to the 462 frequency. Your radio should also be set with a +5.00 offset. This allows your radio to transmit on the 467 frequency. Thus, technically, you should be tuned to both frequencies at the same time.

Correct. Here is an example. If you are programming for what many would call a ‘550’ repeater. Your radio would be tuned to 462.5500 MHz (this is the the frequency you listen on). Your radio would be configured to transmit +5 MHz higher on 467.5500 MHz. This is called a 5 MHz positive offset.

Now I think I've got it! Still not getting anyone on the repeater though. I guess I'm just in a dead zone for GMRS. Thanks for all the help!

[jerrytheyounger]

One more thing. Is the +5 entered 05.000 or .500?

[jerrytheyounger]

I got it! Nevermind. Thanks for everything once again!

There are things called access codes for most repeaters. you will need the input and output code (usually CTCSS or DCS) These need to be entered into the radio as well in order to activate the repeater and talk into it.

I've got a code question. I can hear the repeater but can't get out of it. I'm wondering if I have my code modes wrong. Does anything jump out to anyone?

 

 

                 Tone Mode         DTCS Code    DTCS Code RX     DTCS Pol    Cross Mode          Duplex    Offset    Mode    Power

 

462.0000  CROSS              145                 036                          NN              DTCS->DTCS           +         5.0000     FM      High

 

The codes and offsets are correct but I'm unsure about the rest.

 

Thanks Grendel

Frequency listed is not a GMRS frequency.

Are you sure the repeater is using DCS codes and not CTCSS codes?

Are you certain that different codes are being used for Tx and Rx?

I am speculating based on the way information is formatted in my viewer, but it looks like you might be using DCS with inverted polarity. Is the polarity of the DCS codes correct?

The "NN" means "Normal/Normal" DCS polarity. If it were "IN" it would be "Inverted/Normal" - etc.

 

Grendel6522: I assume you were just truncating the actual frequency, and that you aren't actually trying to use a repeater on 462.000 MHz, right?  That's NOT a GMRS repeater.
