    Output and Input?

    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

  2. Radio is plentiful off Ebay while gun parts and ammo is always out of stock if I were you barrels and scope first...

  3. Good Day and welcome to GMRS. First off you are in the right general area, but the frequencies you list are not official GMRS frequencies. Refer to the official list of frequencies and make sure you entered them correctly. For repeater use, you need use what are referred to as the main GMRS frequencies. The Rx frequency will being with 462, and the Tx frequency will be exactly 5MHz higher and begin with 467. Regarding beeps, that may be Morse Code. Morse code is one method regularly used by repeaters to comply with FCC identification requirements. A repeater will transmit that every 10 to 15 minutes when the repeater is active and often immediately upon becoming active if it has been idle for more than 15 minutes. You could be hearing something else completely different if you are not using correct frequencies. Now, assuming you had a typo and actually used the correct frequencies, one of the things you will learn about radio is what is called “desense”. Desense is the condition where a radio cannot operate properly when it receives strong RF signals that are different from its intended receive frequency. When using radios with a repeater, the radios transmit on one frequency and receive on another. If your handheld radios are sufficiently close to one another, the transmitting radio frequency may be overloading the. receiving radio which is trying to listen on a different frequency. If desense is your problem, you may find that separating the radios by a good distance (perhaps 50-100’ or more) will solve your problem. A good way to visualize desense is this. Imagine its night and you are trying to read the front license plate of a car from 100’ away. You can read it because the license plate is dimly lit and you have good eyes. Now someone turns the headlights on and suddenly you are blinded by those bright lights and consequently your eyes can no longer tune into that dimly lit license plate between them. Lastly, it is very common for repeaters to continue transmitting for 1-2-5 seconds after you stop transmitting. This is done for a variety of reasons. One benefit of this to you when you are testing is that you can key-up, announce your callsign and that you are testing, then under. If you made it into the repeater you get the benefit of hearing that squelch tail from the repeater. Generally a good sign you got in. Never do this without announcing yourself. Hope this helps.

  4. Hello there! I am in the north texas area, call sign WRJV736. I just figured out how to hit a repeater in the DFW area literally 15 minutes ago.

  5. I love my iCOM's I got a Commercial grade radios F221-s, F621TR to name a few Pros: Build like a tank, cheap, software is free, cable readily available or you can make your own Cons:Some are front panel programmable but mostly are not.

  6. Could you point out the rude part of my comment? I asked for secondary help, no sarcasm or rudeness in the text. I truly wanted to know how far down to scroll. Thanks for the detail I was hoping to find. Is there a time limit on how far back the search feature works on? I really used it and came up blank.
