Not sure if this link will let you in. You are suppose to sign in to get there. https://walkietalkiesoftware.com/portal/index/software_detail/id/68.html

Have you tried it the other way, writing the file that bricked the first three into the fourth to see if it bricks it as well? If it does then you know it’s that file, but at the cost of yet another radio. If it doesn’t then you know you got three bad radios from the dealer. I admire persistence.

You can't use chirp to update the firmware. You need their IAP program.

just tell her is wind generating tower and you have to build it in 'phaes'

Exactly! The rules limit certain aspects of the use, but leave it up to us to imagine how we might benefit from it.

I have 1 working tdh3 that has the same version as the 4 non working tdh3’s. I have opened that radio in chirp and then downloaded that file into the other tdh3’s and still no joy. I have programmed multiple radios through chirp and have never had an issue. I appreciate everyone reaching out. I will try downloading new firmware or updating the firmware. Reset on the menu and ptt + star + power on resets have not helped.

Although I don’t have TDH3 radios, I agree that it sounds like whatever you’re doing with Chirp is causing them to cease transmitting. I assume you looked at the column in chirp that enables transmitting and it’s set appropriately. And you say that a full factory reset does not return the radios to being able to transmit? I would recommend returning them for a refund and getting something else.

Implies a dedicated system is not just something I made up. Saying that a Fixed Station may only communicate with other Fixed Stations is the very meaning of the word “dedicated”. Then I said “such as” because I used two relatively easy to understand examples, but using the words such as also implies that there may be other uses. The regulations do say Digital Data is limited to handhelds, but analog data and controls have no such constraint and can be passed using tones, such as DTMF. Digital data. GMRS hand-held portable units may transmit digital data containing location information, or requesting location information from one or more other GMRS or FRS units, or containing a brief text message to another specific GMRS or FRS unit.

Ya, he's guessing at how it could be used. And I agree. I also agree there can be many more uses for it too. The only limitation would be your imagination and the 15 watt output.

yep, I understand the word, but I was saying he made that up and he can use it if he wants but I want interpretation or examples from the people in charge - why is that so hard for so many to people to understand

"Implies"

Except they didn't say that. And isn't data only for handheld? I can't picture what a 2-way intercom would be but I don't need to know anyway.

You have to complete the NCVEC form 605 and on that form, there's a box to check if you want to change your callsign systematically. If checked, you will automatically be assigned a new callsign when your upgrade is processed by the FCC. So it kind of is automatic if you request it. Until then, you can use your current callsign/AE and operate with your new frequency privileges. Also, you don't need to pass ANY exam in order to request a new systematically assigned callsign. You could submit form 605 to a VEC or submit the request online through the FCC license manager site.

Has no relevance. Ham doesn't have the fixed station type and GMRS doesn't have microwave, and you can't mix services.

If one passes their AE exam, they keep their original call sign unless they can find a vanity call they like that's available and apply for the change. You won't get issued anything automatically just because you passed the exam. Getting AE only qualifies one to apply for any available call and one will not automatically get reassigned a new or shorter call.

Shame on me! I thought even the south end of a north bound horse would realize the example of microwave stations were just that, examples of fixed stations.

I have been here myself with a new H3. Please troubleshoot /check the radio's antenna port pin for visible damage/broken off. Please also examine the cable and the inline SMA adapters used during testing. Poor antenna port connection problems might affect your Finals, Output, and Reliable Repeater Connections. I have history here. I think the current CP is corrupted and not actually writing to the radio what you think. If you have a reliable H3 available, you can easily upload this good CP from this reliable HT >into Chirp> and then write that reliable CP to the non-working unit. Loading a reliable code plug is better than a Reset in my experience with multiple brands. In Chirp, always confirm that the Vendor and the Model are correct. Best Regards!

The regulations tell us exactly what is required of a Fixed Station and what a Fixed Station may do. They just don’t provide an example of how it might be used, and that’s good, because it leaves it up to the imagination of the user. 1. A Fixed Stations may only communicate with other Fixed Stations. The regulations do not limit it to just one other Fixed Station. This implies a connection to a dedicated system, such as telemetry or part of an intercom system, where the Fixed Stations have a single purpose. 2. A Fixed Station is limited to 15 watts. This makes sense for a system of dedicated radios in fixed locations where the distances and directions never change, such as two or more points in an intercom or telemetry system. It also reduces the likelihood of interference with other stations, especially if a person uses high gain directional antennas, such as parabolic dishes or Yagi antennas. 3. Fixed Stations may transmit on both the 467 MHz and 462 MHz main channels. Although simplex isn’t prohibited, this unique carve-out in the regulations makes it possible to operate full duplex between two Fixed Stations, transmitting and receiving simultaneously, which allows for very natural speech on an intercom system and is ideal for transmitting data and controls on a telemetry or SCADA system. So, for a family business (or a business which has a grandfathered license that covers their employees) Fixed Stations could be used for a wireless intercom. A farmer could use Fixed Stations to turn irrigation systems on or off several miles away. With the exception of the ability to operate in full duplex, which is made possible by being granted access to the 467 MHz main channels, all of these examples could be done as well or better with portable, mobile, or base stations. But for a system which is dedicated to a particular purpose between two or more fixed locations, such as telemetry or an intercom, where full duplex would a distinct advantage, using Fixed Stations would be a reasonable solution.

Speaking of which, why do we park on the driveway and drive on the parkway?

In the software, click on "Phone System" on the left. In the "Phone System" screen that comes up, edit the "Radio ID Code" on the right.

I have received 16 TD H3s. I bought 14 and 2 were bad and they sent me 2 more. I don't use chirp. The TD H3 has it's own CPS that works well and is similar to the way chirp works. So use the H3 CPS. Have you tried to update the firmware to revitalize the "broken" H3s? You can even install the same firmware and overwrite the existing.

I’m beginning to think so too

And people tell me I’m nuts when I say h3s stink. Every one I know that has fell for them has a 50-75% fail rate. Vote me down all you want guys. This is just more evidence h3 radios are total junk.

And….now the two tdh3’s that took the place of the prior two that didn’t transmit now have the exact same problem. I think Chirp is bricking them somehow. They worked great for about 2 weeks and now zero output wattage. I’ve done nothing to them other than fiddle around chirp programming channels and repeaters. Resetting the radios did nothing. Wow. Stumped beyond belief. I’ve got two uv5g’s, 1 uv5g plus, and had 5 tdh3’s and out of 5 tdh3’s 4 of them have went to zero output wattage on my surecom meter after previously showing 3.7 watts. Gosh I hope I can sort this out. It’s not the meter because none of these tdh3’s will open local repeaters and they used to.
