No, I have never been able to see it either. I see a huge blank area at the bottom of every one of your posts that says dead sticker.jpg, so I have an idea what it’s supposed to be. But if I click on it I also get the 403 warning. You’re definitely not on my ignore list.

TIDRADIO TD-H3 Identification send feature - how does it work?
SteveShannon replied to TrikeRadio's question in Technical Discussion
I’ve not heard of ANI ID’s being displayed on the screen of another radio, although it makes sense that some devices can interpret them. Nor do I know if they are delivered through a repeater. This has been discussed before on the forum but I don’t recall anyone having great success using them. They’re more of a feature used by commercial radios and maybe the people here who deal with commercial radios can advise you more. @nokones, @Lscott, @gortex2, @marcspaz Here’s a thread on radio reference that discusses the various settings and how they’re used referring, to a Baofeng UV-82. It might be useful anyway. https://forums.radioreference.com/threads/baofeng-uv-82-need-help-with-understanding-ani-id-signal-code-ptt-id.282829/ The post that appears to have the most helpful information about the subject is #10. I haven’t tried any of this. I’m curious what you intend to do with ANI-ID? -
TIDRADIO TD-H3 Identification send feature - how does it work?
SteveShannon replied to TrikeRadio's question in Technical Discussion
Maybe it doesn’t really send it. I believe you have it set correctly although are you waiting slightly to allow the code to be sent before you speak? Try it in the ham mode (assuming you’re licensed appropriately.) -
No, the station has nothing to do with the building your station is in. You can have a GMRS station placed right next to your ham station on the same desk, in the same jeep, or on the same belt. You simply use the other radio. But only if you have the appropriate license. I have both and as long as I remember to grab the right microphone and use the right call sign I can have a two way conversation to either service. But I agree with you that hams should not be lecturing GMRS licensees and vice versa. I don’t agree with your premise that amateur radio operators are necessarily more educated and experienced. They are more tested however.
-
As far as communicating between a ham station and a GMRS licensee, it could be easily done by having the ham transmit on a ham frequency and received on a ham receiver by the GMRS licensee. No rule prohibits any person from receiving on ham frequencies. Then the GMRS licensee could transmit on the GMRS station. No rule prohibits any person from receiving on GMRS frequencies. But both transmissions would violate the regulations against one way transmissions.

Nearly everything of significance is defined by the FCC. GMRS is one of the Personal Radio Services. Here’s the definition of a station: Personal Radio Services station. Any transmitter, with or without an incorporated antenna or receiver, which is certified by the FCC to be operated in one or more of the Personal Radio Services.

Welcome Mark! 462.675 is the frequency you receive the repeater on. So it’s sometimes known as the repeater output frequency. If you use a GMRS radio the offsets are automatically set. On GMRS you always transmit on 467.xxx MHz frequencies and receive on 462.xxx MHz frequencies when you use a repeater channel. Disregard user socalgmrs. He’s having a bad day. Apparently he feels better about himself when he’s scolding new people. Feel free to ask questions. Welcome to the forum.

GMRS channels vs Repeater Channels

GMRS channels vs Repeater Channels
SteveShannon replied to WSFP666's question in Technical Discussion
Correct. The offset should be automatically added for the repeater channels (RP15 - RP22) and the other channels (1- 22) shouldn’t have any offset. Channels 1-7 are limited to 5 watts. Channels 8-14 are probably not available to you. Channels 15-22 are limited to 50 watts, as are the repeater channels. -
Atan(70/2640) = 1.5° The height difference should not matter.
-
That’s exactly why we work in decibels. You just add them together. So rounding off all to -3 db per 100 feet for lmr400, 1.40 x -3 db = -4.2 db. -4.2 db + 11.9 db leaves you with 7.7 db gain. I assume the 11.9 db you quoted for the antenna is dBi. So, compared to an isentropic antenna you’re radiating a little better than four times as much power horizontally. If the antenna gain was actually expressed as dBd you add 2.15 db to it and the result is 9.85 db gain which is about eight times as much power.

Forced low power on repeater channel 17
SteveShannon replied to WSCW398's question in Technical Discussion
Some manufacturers confuse the issue by naming repeater channels RP15 through RP22. Other manufacturers simply continue the numbering from 23 through 30, so when you said Repeater Channel 17, you were really on channel 17, which is not a repeater channel. Second, I am not familiar with the radio shown and I don’t want to add confusion. It appears to show T-DCS is OFF. Does that mean it isn’t sending a DCS code, @OffRoaderX? -
Best GMRS channel to monitor for traffic
SteveShannon replied to WSEN722's topic in General Discussion
Monitoring for traffic can have a couple connotations. Radio traffic or highway traffic reports on the radio. When I first read the question I wasn’t sure which was being asked. -
You’re right. I misunderstood what this device was. Here’s a picture of it in use (as a marketing model).
-
People come to forums to ask questions. That’s perfectly normal. In fact it’s good that they have someplace to come and ask questions. The OP may have been confirming his own understanding of the regulations. Responding like a total buttplug every time someone asks about the regulations is abnormal.

I’m not a telescope expert, but I believe this is the kind of device my friend used to take the Spaghetti Nebula photo above: https://www.highpointscientific.com/zwo-asi2600mc-duo-built-in-dual-sensor-astronomy-camera?utm_source=google&utm_medium=cpc&utm_campaign=1360885342&utm_content=61324494144&utm_term=&gad_source=1&gbraid=0AAAAAD-khUbxpGaSORu3Yipm-cdS4E-5t&gclid=CjwKCAiAxea5BhBeEiwAh4t5K29icn6xlqXGdkcmxvtZZ3axpIhvgIy1FW0364WYcUTIhPHYiy-tnhoCpaQQAvD_BwE

No. New GMRS Licenses are only issued to individuals. For your CERT team to use GMRS each person would require his or her own license, except for family members of a license holder who may be authorized to use the license holder’s stations.

You don’t need a physical com port like a db9 or db25. Your USB ports are mapped as virtual com ports by the drivers that come with the programming software. You will be able to see them appear in Device Manager.

A mobile antenna on a pie plate in front of a window can do a pretty decent job. If I lived closer I’d help you put one in your attic.

The VX-6R is the radio to have in case of the apocalypse. Immersion proof, metal chassis, and reliable. I like it. It’s not cheap and it isn’t loaded with features like APRS or digital audio, but it receives across a very wide range.
-
Although I don’t use it on GMRS, it’s a fine little radio. It fits nicely in a jacket pocket. I use it mostly for short distances and I put a stubby antenna on it for that reason.
-
I would call the dealer and rant and rave. They might replace the radio that has a short. They might replace both radios. If the radio they sold you started a fire in your house your insurance company would have no problem calling them. The radio that had been working well is probably okay since the overheating happened when you put the battery into the other radio. I wouldn’t use either battery though.

That’s simply not true. Although some GMRS channels are limited to handheld radios, and some channels are limited to 5 watts, no regulation limits handheld radios to 5 watts when mobile radios are allowed. There are practical reasons to limit handheld radios to low power but not regulatory. Here are the power regulations: 95.1767 GMRS transmitting power limits. This section contains transmitting power limits for GMRS stations. The maximum transmitting power depends on which channels are being used and the type of station. (a) 462/467 MHz main channels. The limits in this paragraph apply to stations transmitting on any of the 462 MHz main channels or any of the 467 MHz main channels. Each GMRS transmitter type must be capable of operating within the allowable power range. GMRS licensees are responsible for ensuring that their GMRS stations operate in compliance with these limits. (1) The transmitter output power of mobile, repeater and base stations must not exceed 50 Watts. (2) The transmitter output power of fixed stations must not exceed 15 Watts. (b) 462 MHz interstitial channels. The effective radiated power (ERP) of mobile, hand-held portable and base stations transmitting on the 462 MHz interstitial channels must not exceed 5 Watts. (c) 467 MHz interstitial channels. The effective radiated power (ERP) of hand-held portable units transmitting on the 467 MHz interstitial channels must not exceed 0.5 Watt. Each GMRS transmitter type capable of transmitting on these channels must be designed such that the ERP does not exceed 0.5 Watt.
