Something very strange is happening
SteveShannon replied to SvenMarbles's topic in General Discussion
A certified FRS radio shouldn’t be able to transmit on the repeater input frequencies. But those kids (and their folks) could have been using GMRS radios. -
Make sure you’re at the mygmrs.com level, NOT the forums.mygmrs.com level. It’s only at the higher level that you can change your username. Rich gave us that ability about a year ago.

We’re at that age (I assume) where we help those who need help. It’s not always easy but it’s rewarding in its own right.

GMRS repeaters northwest Louisiana
SteveShannon replied to WSGH650's topic in National and Regional GMRS Nets

Exactly. The reason I ordered the UV380 was because I’d been programming code plugs for a blind/deaf (mostly) ham friend. The OpenGD77 and OpenUV380 software supports a fairly rich set of voice prompts which are a huge benefit to my friend. For the Anytone/Alinco model I found that the only way to make channels easier for him were to exactly duplicate the channels for every DMR zone. That way he could memorize the numbers of the zones and the numbers of the channels within the zones. So, channels 191, 291, 391, … all pointed to Talk group 91, the North American talk group, differing only in zone number. But as you say that’s a lot of duplication and ends up with many channels that differ minimally. The OpenGD77 model is much more intuitive.

I agree, but recently I repleaced the firmware in a couple of TYT MD UV380 handhelds with OpenUV380. It is actually intuitive compared to the Anytone model which my Alinco radio used. You program repeaters, just the way you would an analog repeater, except of course you need to include color code and time slot. Then you group the talk groups into “talk group lists”. Finally you associate each repeater to a talk group lists. No more having to individually program every single talk group for every single repeater. It’s even easier and more intuitive than using the DMR calculator supplied by RT Systems.

It’s pretty easy. Edit your profile at the mygmrs.com level and enter a new username.

There are some things to be careful of. If you get a LiFePO4 battery and intend to charge it from the alternator, there are special chargers that need to be used to avoid burning out your alternator. There are lots of YouTube videos about it. I haven’t done it and have no experience.

Yes, it’s possible. A secondary battery would be the most efficient and have the least opportunity to create noise, but there’s no guarantee it’ll be a perfect cure.

New to GMRS questions and programming radio for a repeater
SteveShannon replied to a topic in Guest Forum
Good job! -
No, I know of Wilsall . My dad’s cousin owned the Clyde Park Tavern in the 70’s or 80s.

It wasn’t a stupid question.

1. It really depends on the repeater how much traffic you hear, but the nature of Famished that you only hear one transmission at a time. Let us know if I misunderstood your question. 2. Tune to the correct repeater channel. Program the repeater’s input tone or code into your radio as the TX CTCSS or DCS. At first, leave the RX tone empty so you hear all traffic; you can always go back and set it if you receive too many transmissions that don’t come from the repeater.

Hi John, For GMRS and FRS, the FCC has designated 22 specific frequencies for our simplex use and 8 more for transmitting to the repeater. The channels are interlaced. So tuning to an “in-between” frequency might be interfering with other services or other channels. You’ll definitely want to read the regulations to see what frequencies we are allowed and the power and bandwidth: § 95.1763 GMRS channels. The GMRS is allotted 30 channels—16 main channels and 14 interstitial channels. GMRS stations may transmit on any of the channels as indicated below. (a) 462 MHz main channels. Only mobile, hand-held portable, repeater, base and fixed stations may transmit on these 8 channels. The channel center frequencies are: 462.5500, 462.5750, 462.6000, 462.6250, 462.6500, 462.6750, 462.7000, and 462.7250 MHz. (b) 462 MHz interstitial channels. Only mobile, hand-held portable and base stations may transmit on these 7 channels. The channel center frequencies are: 462.5625, 462.5875, 462.6125, 462.6375, 462.6625, 462.6875, and 462.7125 MHz. (c) 467 MHz main channels. Only mobile, hand-held portable, control and fixed stations may transmit on these 8 channels. Mobile, hand-held portable and control stations may transmit on these channels only when communicating through a repeater station or making brief test transmissions in accordance with § 95.319(c). The channel center frequencies are: 467.5500, 467.5750, 467.6000, 467.6250, 467.6500, 467.6750, 467.7000, and 467.7250 MHz. (d) 467 MHz interstitial channels. Only hand-held portable units may transmit on these 7 channels. The channel center frequencies are: 467.5625, 467.5875, 467.6125, 467.6375, 467.6625, 467.6875, and 467.7125 MHz.

Line A and C Inquiry and Update from the FCC

Thanks for the reminder of how to print the official copy. I always have to fumble around a little bit too. -
Something very strange is happening
SteveShannon replied to SvenMarbles's topic in General Discussion
Nothing about the general personal radio services regulations nor those of part B (FRS) or part E (GMRS) support the position that a licensed user has a greater right to the 22 shared channels. -
Are you sure?

95.531(b) One-way communications. FRS units may be used for one-way communications that are emergency messages, traveler assistance communications, voice pages or brief equipment tests. § 95.533 Prohibited FRS uses. FRS units must not be used for one-way communications other than those listed in § 95.531(b). Initial transmissions to establish two-way communications and data transmissions listed in § 95.531(a) are not considered to be one-way communications for the purposes of this section. -

You’re joking, right? -

SteveShannon replied to SvenMarbles's topic in General Discussion
I agree and both broadcasting and one way communications could be cause for citations, but it wasn’t always 24/7 according to his description. It appeared once for what sounded like a period of days (that would be 24/7 at the time) then reappeared again a few weeks later. This is a clear case of parents being ignorant about the technology they’re using. But using GMRS frequencies, regardless of how important a person might think his communications are, includes sharing with ignorant people. I like @WRUE951’s suggestion to educate the parents, but if it’s kids with a set of FRS walkie talkies using VOX, there’s not much that can be done legally. -

Calling it a “GMRS repeater frequency” implies more than actually exists. 22 isn’t dedicated to repeaters. It’s available for FRS simplex, GMRS simplex, and as the output of a GMRS repeater. It might suck, but legal FRS users have as much right to use it as GMRS users. But the actions you describe are excellent reasons why people shouldn’t use wireless intercoms or baby monitors, regardless of the frequency. -
I remember reading about that shortly after it happened. Some articles include the fact that he’s a ham in the headline, but that had nothing to do with the fact that he was disrupting their communications on 151 MHz and attempting to redirect firefighting resources. I would have loved to see the interaction when the official drove over to his location and clarified things. I have absolutely no sympathy for this jerk. He’s the kind of guy that reflects poorly on all hams.

SteveShannon replied to SvenMarbles's topic in General Discussion
That’s a good point. One way transmissions are limited to certain uses; a baby monitor isn’t one. But if it’s a two way intercom triggered by sounds I’m not sure what the FCC might think. -

Or a legal use of an FRS channel.
