CTCSS and DCS do the same thing, just using slightly differently encoded tones. DCS encodes the tones as digital signals, whereas CTCSS actually generates an analog tone between 62 Hz up to almost 300 Hz. It’s just a choice, but there are more digital tones and they can be inverted as well. Just use whichever the radio or repeater you with to transmit to requires. The receive tone can be left off. If you leave it off you will receive everything transmitted on that frequency. If you correctly program the receive tone you will only hear signals that are transmitted with the same tone. That may prevent you from feeling interrupted, but your radio hears everything so there can still be interference. I tend to leave the receive tone off. It’s one less thing to go wrong and I live where there’s very little traffic.

It really is perfect for this. The 2 watt power and VHF range, plus simple radios and clear frequencies make MURS ideal.

That’s alright; I’m old and demented.

INPUT Tone = TX Tone OUTPUT Tone = RX Tone The words “Input” and “Output” are relative to the repeater. So, your radio transmits the Input tones the repeater requires, and receives the repeater’s Output tones. Set your TX tone to the Input tone needed by the repeater. At first leave the RX tone empty. Once everything is working you can try putting the Output tone in for the RX tone.

As @BoxCar and @WRUU653 both said, the first step in diagnosing reception issues is to clear out the receive tone or turn off tone squelch. The reason is that a radio without a tone for receive will hear everything within range on that frequency. A receiver with a tone set will only break squelch for transmissions that match the tone. Some radios have a “Moni” button that gets around all of that. But you said you get absolutely no sound. If so, check to see: are you able to receive audio from other channels? If not, then have you recently plugged in a cable to program your radio or an earphone cable? It’s not an unknown problem for an earphone or microphone jack to fail, leaving the owner puzzled why they cannot hear or why nobody can hear them. A friend of mine with a UV5R was transmitting to the repeater and we all saw a good signal strength, but none of us could hear him. His microphone jack failed, leaving the radio in a state where the internal microphone is bypassed. It sends carrier (and roger beep, which is how we knew who it was) without audio. He’s able to plug-in a microphone and use it though. If there’s a possibility something like that happened, plugging in an earphone might help.

Welcome! If I have correctly parsed your message, it sounds like maybe you would also like to get your ham license. It’s as easy as it ever has been. If you need any help with that I can recommend a good teaching tool.

Another thing to try would be to have the actual owner add them back in to his/her list of repeaters. Don’t blame yourself. This seems to me to be either a bug in the code, a case of incorrect permissions, or really a poor design.

I really wasn’t recommending it. It was a theoretical response to a theoretical question. ? Personally, I would go with a yaesu ftm-6000.

The extra length of the section of all-thread makes for an antenna that is even more susceptible to buffeting by air currents. Any distortion due to Doppler or picket fencing will be more noticeable on weaker signals. You might try a higher gain antenna, such as a no ground plane roof mount antenna mounted without the all-thread.

If the all-thread were 1/4 wave and not connected to the vehicle it would be a true dipole. In a true dipole both halves are balanced radiating elements. But since it is connected to the car chassis (ground) it’s just a quarter wave vertical with a vertically extended ground plane. I don’t expect it to hurt but experience will tell you. Having part of the ground plane be a vertical element may be beneficial, but I have no idea how much. Certainly getting the antenna higher up will help.

@WRVJ335 See if you can remove them from “My Listings”

In order: 1. Yes. If necessary you can always add a fan. 2. No. 3. Not at all. No, you are not better off setting up a repeater and using an HT, especially if you’re trying to hit another repeater. 4. Sorry, I haven’t. Please share your pictures though. 5. No, being in a wooden cabinet will not cause interference.

I looked at Nesbit 304. The problem is that you appear as the owner, even though in the map it appears that WRPN902 is the owner. I’ll report your post to Rich (owner of the site). It’s obviously a problem with the software that allows people to somehow appear as owners of repeaters. We saw it happen last week also.

Try swapping antennas to see if that helps. Your UV9px is a dual band amateur radio and not optimized for 472.700 (and if you really mean a GMRS frequency that’s 462.700 MHz.) Antennas can make a huge difference. I bought two Radioddity GMRS 20 watt radios and Midland GMRS antennas. I unlocked one of the radios so I could use it on 70 cm and 2 meter. I tried talking to a ham friend five blocks away on my street on 2 meters using the GMRS antenna. He could hear me, but I couldn’t hear him. I was transmitting using 20 watts. He was using 5 watts. On 70 cm I could hear him and vice versa. I bought a Comet dual band antenna and now, on the lowest power setting on my radio, which is only a few watts, he hears me perfectly and I hear him perfectly even a few more miles away in city buildings.

1 - improved testing conditions which don’t reflect your actual needs are not helpful. Have you tried changing the squelch? 2 - see bold portion below: c) No GMRS transmitter will be certified for use in the GMRS if it is equipped with a frequency capability not listed in § 95.1763, unless such transmitter is also certified for use in another radio service for which the frequency is authorized and for which certification is also required. No GMRS transmitter will be certified for use in the GMRS if it is equipped with the capabilities to operate in services that do not require equipment certification, such as the Amateur Radio Service. All frequency determining circuitry (including crystals) and programming controls in each GMRS transmitter must be internal to the transmitter and must not be accessible from the exterior of the transmitter operating panel or from the exterior of the transmitter enclosure.

Clearer, perhaps, because of signal to noise ratio, but I have never heard anyone tell people to turn up their power if their audio is simply low. We’ll tell them to turn up their mic gain, or maybe engage compression, or to speak more directly into the microphone.

Finally, these are the prohibited uses named in the GMRS section (Part E): § 95.1733 Prohibited GMRS uses. (a)In addition to the prohibited uses outlined in § 95.333 of this chapter, GMRS stations must not communicate: (1)Messages in connection with any activity which is against Federal, State, or local law; (2)False or deceptive messages; (3)Coded messages or messages with hidden meanings (“10 codes” are permissible); (4)Music, whistling, sound effects or material to amuse or entertain; (5)Advertisements or offers for the sale of goods or services; (6)Advertisements for a political candidate or political campaign (messages about the campaign business may be communicated); (7)International distress signals, such as the word “Mayday” (except when on a ship, aircraft or other vehicle in immediate danger to ask for help); (8)Messages which are both conveyed by a wireline control link and transmitted by a GMRS station; (9)Messages (except emergency messages) to any station in the Amateur Radio Service, to any unauthorized station, or to any foreign station; (10)Continuous or uninterrupted transmissions, except for communications involving the immediate safety of life or property; and (11)Messages for public address systems. (12)The provision of § 95.333apply, however, if the licensee is a corporation and the license so indicates, it may use its GMRS system to furnish non-profit radio communication service to its parent corporation, to another subsidiary of the same parent, or to its own subsidiary. (b)GMRS stations must not be used for one-way communications other than those listed in § 95.1731(b). Initial transmissions to establish two-way communications and data transmissions listed in § 95.1731(d)are not considered to be one-way communications for the purposes of this section

FRS has similar language that permits business use: Family Radio Service (FRS).A short-distance two-way voice communication service, with limited data applications, between low power hand-held radios, for facilitating individual, family, group, recreational and business activities.

It depends on what you’re doing commercially. First, these uses are forbidden for all public radio services: § 95.333 Prohibited uses. No person shall use a Personal Radio Service station: (a)In connection with any activity which is against Federal, State or local law; (b)To transmit advertisements or program material associated with television or radio broadcasting; (c)To transmit messages for hire or provide a common carrier service; (d)To intentionally interfere with the communications of another station; (e)To transmit obscene, profane or indecent words, language or meaning; or (f)To transmit a false or deceptive communication. So clearly you cannot spam listeners or charge to deliver messages.

Yes: § 95.1731 Permissible GMRS uses. The operator of a GMRS station may use that station for two-way plain language voice communications with other GMRS stations and with FRS units concerning personal or business activities

Here’s a pretty good test of several. If you want greater range it appears the Long Ranger or similar are tops. Signal Stick was okay.

Somehow I missed the first period. ? I read: Nowhere in the CURRENT rules does it say that FRS can use up to 2 watts (depending on the channel). Definitely my mistake.

Maybe I’m misunderstanding your point, but here’s what the FRS rules say about power: § 95.567 FRS transmit power. Each FRS transmitter type must be designed such that the effective radiated power (ERP) on channels 8 through 14 does not exceed 0.5 Watts and the ERP on channels 1 through 7 and 15 through 22 does not exceed 2.0 Watts. It’s true that output power may be different from ERP.
