FCC PART 95 (G) SUBPART (C) PARAGRAPH 2
SteveShannon replied to WQAI363's topic in Family Radio Service (FRS)
If they were still alive… A license elapses when the licensee expires. Here’s the actual regulation: 2) Any individual who holds an individual license may allow his or her immediate family members to operate his or her GMRS station or stations. Immediate family members are the licensee's spouse, children, grandchildren, stepchildren, parents, grandparents, stepparents, brothers, sisters, aunts, uncles, nieces, nephews, and in-laws. -
There’s the FT70, but his collection is built on higher end hardware, isn’t it? Also the FT70 doesn’t APRS.

The FT5DR was down to $329 during hamvention. Maybe still.

People are quick to say “in an emergency” as if that excuses all sorts of non-compliance, but the truth is that non-compliance during an actual emergency is more likely to be detrimental to those who need effective communications. A recent example was the jerk who interfered with fire-fighting crews by getting on the radio and trying to redirect their efforts to what he considered an emergency. The regulations do allow certain behaviors in an emergency but you must read the actual language of those exceptions. None of them amount to “anything goes.” But you are correct that the FCC might not even investigate unless a complaint is made.

Microphone 8 Pin Connection wiring for Wouxun
SteveShannon replied to CentralFloridaGMRS's question in Technical Discussion
Pictures always help. In this blown up shot of your previous image it appears that you have one white and one gray. You also have one shield wire which has no insulation. -
Microphone 8 Pin Connection wiring for Wouxun
SteveShannon replied to CentralFloridaGMRS's question in Technical Discussion
Well, they’re only $25 and if you use the new one to figure out the connections you’ll have a spare. Good luck! -
Here’s what the regulations say: § 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);

New Repeater Channels for GMRS in 2024
SteveShannon replied to intermod's topic in FCC Rules Discussion
DMR channels do not use 7.6 kHz of spectrum; they each use 12.5 kHz but they use time division multiplexing to share that portion of spectrum. In other words each current GMRS channel would only represent two DMR channels. Gil is correct that this would impact everyone who has an analog GMRS radio. Use of such a radio requires the entire channel, making it unavailable for DMR. Conversely, to those who have analog radios, every DMR transmission sounds like an impact wrench. “Here in California, CERT, neighborhood or fire watch, militia groups, etc. have implemented GMRS because 80-90% of their members have no direct interest in the technical aspects of amateur radio.” I don’t know how true that statistic is, but ruining GMRS for the rest of us isn’t the answer. P.S. People who have no direct interest in the technical aspects of amateur radio might have a tough go when they have to program a codeplug. DMR codeplugs are extremely technical. I guess you could sell the radio with a basic codeplug that’s simplex DMR on 1-22 and duplex on 23-30, but what do you use for talk groups, time slots, and color codes? -
Microphone 8 Pin Connection wiring for Wouxun
SteveShannon replied to CentralFloridaGMRS's question in Technical Discussion
Which three were off when the Mike stopped working? What functions stopped working as designed? You probably documented where the other five went before you removed them. Which pins did they go to? -
You’ll need to program your radio with the transmit tone. Without the TX tone the repeater will ignore your transmission. Usually it’s just a setting for each channel. Your manual should show you where. Look under “privacy tones” or CTCSS. It’ll be in that section. FYI “privacy tones” don’t protect you from eavesdropping.
-
That frequency is the one you listen to. Yes, TX is up 5 MHz and that’s where you must use the DCTS tone to get into the repeater. If your radio is a certified gmrs radio the offset will already be included when you choose a repeater channel (15RP - 22RP or 23-30 depending on how your radio has them labeled.) I recommend leaving the tone off of your receiver at first, so you can be sure you get in. If you’re bothered by hearing other non-repeater traffic on the frequency you can always add DCTS to your receive channel.

Is a duplexer required for a repeater
SteveShannon replied to WRWE744's question in Technical Discussion
Have you done this before? -
It was very clear what you meant from the context of the conversation.

One nice thing about GMRS is that radios which are certified for use for GMRS come preprogrammed with the correct channels. All you have to do is choose one of the repeater channels and set the tone to access the repeater. So, for most GMRS radios, channels 1-22 are not for use with repeaters, but rather for direct communications using a single frequency, which is known as Simplex communications. The repeaters reuse channels 15-22 for receiving, but add eight more frequencies, which are almost always exactly 5 MHz higher than the receive frequencies. That’s done usually without you needing to know much about how it works. The repeater channels will often be called something that implies that relationship. So, for instance, 15RP would be the “channel” that you set your radio to which receives on the same frequency as 15, but transmits on a frequency that is 5 MHz higher. The frequency offset is necessary for a repeater to transmit at the same time it receives, which is called Full Duplex. Channel 15 for example is 462.550 MHz. Channel 15RP receives on 462.550 MHz, but automatically transmits on 467.550 MHz. You should not be entering frequencies for transmitting and if you have a radio that’s certified for GMRS you don’t have to. Sometime the company doesn’t call the repeater channels 15RP through 22RP. Sometimes they number them 23-30, but it means the same thing. I echo the others who recommended watching Notarubicon videosas a way to get started in GMRS. As Marc pointed out GMRS and Amateur Radio are two completely different service. In GMRS you simply buy a license and radio and begin using it. GMRS is primarily about using the radio for short range personal communications. Amateur Radio encompasses that and much more.

Interference, point me in the right direction.
SteveShannon replied to Josh00333's question in Technical Discussion
So even with the engine off you get the whine? I would start by pulling fuses to see when the whine stops. Check your owners manual first to make sure you won’t set some off kind of anti-theft measure. Once you know which circuit produces the whine, then maybe you can figure out how to mitigate the problem. The interference is getting into the radio through either power, ground, or the antenna. The question will be can you stop (maybe reduce is a better word) it at the source or where it enters the radio? -
Looking for antenna upgrade recommendation.
SteveShannon replied to WRWE456's topic in Multi-Use Radio Service (MURS)
Maybe that’s because of this regulation: § 95.2719 MURS replacement parts. The operator of an MURS transmitter may replace parts of an MURS transmitter as indicated in this section. All other internal maintenance and repairs must be carried out in accordance with § 95.319. (a)A damaged antenna may be replaced by another antenna of the same or a compatible similar type. -
Since you’re using them with a switch you’re intending to use one at a time. Just keep them one wavelength apart vertically and you probably won’t have any detectable effects. Try it.

That one I can see. That looks nice.

Wouxun ANO-012G GMRS Tuned Antenna back in stock
SteveShannon replied to back4more70's topic in Equipment Reviews
I don’t know if it’s your end or mine, but I don’t see your photos. -
Although the picture doesn't work for me, congratulations on getting this done. The most amazing thing is that you found a piece of actual wood in something from Staples. ?
