Based on GrouserPad’s experience that’s not uncommon, unfortunately. There’s no reason to doubt your (or his) experience. TD H3s apparently arrive dead or die shortly after. Don’t waste time double checking yourself. Send it back, preferably for a different radio. You’re fine starting another thread but you would have been okay piggybacking on GrouserPad’s thread. Welcome to the forum!

i love the stand,, now thats unique

There’s no way for it to get too hot except while transmitting. It’s the final output transistors that require cooling.

Hello! I'm new to mobile radios so I want to make sure I'm not doing something wrong before I send my radio in. I've got four TIDRadio H3s, two GMRS units and two ham units that were unlocked and changed to GMRS mode. I've been trying to hit a local repeater unsuccessfully so I picked up a Surecom SW33 to make sure my radios/antennas are actually working correctly. Three of the four are showing a VSWR around 1.4 and an output wattage around 5W with the same antenna so I think I'm just too far out from the repeater to hit it. The problem is the fourth radio (one of the ham units) doesn't show anything on the SW33 when transmitting. Other radios can hear it transmit short range - I've tested it on simplex channels across the house and through some walls but nothing long distance - but the SW33 is acting like it's not doing anything. (Edit: Should note I also tried it with the 50 ohm dummy load that came with the meter and still got no output reading.) Are there other things I can check or change in my test setup or was this radio DOA and needs to be replaced? (Side question: regarding forum etiquette, should I have piggybacked off GrouserPad's similar thread for this or was starting a new thread appropriate?)

Yes. No matter the setting the fan goes on when the PTT button is pressed and stays on until the machine thinks it's cool enough. If it was on TX then it would only come on when the PTT button is pressed but not come on when the machine is hot. Probably not a good idea. I would assume it has an over ride or just won't transmit when too hot.

The definition of an open repeater is one that has been deemed so by the owner. GMRS repeaters are privately owned. You don’t have the right to list them, only the owner does. Furthermore a repeater having a matching output does not make it open, in fact programming the output (receive) isn’t even need to operate a repeater or hear it.

Have you tried VHT + TX? Doesn’t it only turn on the fan while you are transmitting AND the temperature is too hot?

I need to get back to studying for AE. Same as last years study course, life got busy and I'm behind again.

I did.

I'm hoping that you're not really serious??

I don't know, I will look further into this. Your situation seems unique, with no prior call sign shown before your upgrade. Did you go from unlicensed to AE in one session?

Good morning, same thing happened to me. Granted I literally just upgraded, so I'll give it a bit to trickle through the wickets.

Or unless you request a new sequentially assigned callsign.

My outdoor antenna for the repeater station and a third antenna in the shop window. The attic antenna depicted above post and the window antenna are just used to access repeaters in my area. I have two base station setups and one repeater station.

My brother didn't request a new call sign either. The FCC will not change it unless you request a vanity call sign.

So did mine. Because I didn't request a new callsign.

I have multiple repeaters. None are listed. I dont need or want them listed. Why should others list my repeater ?

You for sure married the right woman. My wife is kinda intrigued by my funny radio "fad", although she does not really "get it" and probably would never pick a radio up and talk into it... but she laughs at some of the funny conversations on our local repeaters. And she still loves me anyway.

It can be set to TX, VHT+TX or ALWAYS. There doesn't seem to be an option to keep it off unless it's hot (VHT)

That can be changed in menu 51.

Thanks for the feedback. I'm not sure if it's a Del Webb home. It's about 40 years old. For the most part it's a well built home. Nothing fancy. The attic over the garage is a good 7ft tall at the peak so I had plenty of room. Mostly I wanted to test the concept and these were the materials I had on hand. I got it all put together right before a local net started. I had to dodge my mother in law who wanted to chatter about what I was doing. Anyway, it seems to work pretty well. I am hearing the drive through girl at the Chik Fil A a few miles away, local highschool football coaches, road construction flaggers etc. More importantly, I can now hit a few repeaters that were out of reach with my HT. I am in a bad spot in this valley for reception otherwise. I am at the low end of the valley, right up against a curtain of mountains that block me to the East and South. You have the altitude advantage with that third floor. What kind of cable are you using?

Here's my little setup. Of course the KG1000G+ radio, then a Jesverty 30A switching power supply with a Surecom 102 SWR meter and my wife's trusty TD H3. The power supply is new. The old one was a Pyramid but lacked the amps to drive the radio. It was able to run my KC XS20G+ to 29 watts out but won't drive the KG1000G+ to 20 watts for whatever reason. The extra power pushed my SWR up from 1.01 to 1.03 on my Comet CA 712EFC antenna. Power seems spot on. On the repeater 467MHz channels it's pushing 49.x watts and on the lower 15-22 channels looks like it outputting a bit over 51 watts. Haven't tried into a dummy load yet. Looks like I'm stuck with my DMR noise, no real change unfortunately. The speaker output is much louder than the XS20G+. The fan coming on every time you transmit is annoying. Guess the silence of the XS20G+ has me spoiled. 3 power settings is really 4. The medium setting has a menu choice of 10 or 20 watts, I keep it at 20. Low outputs 4.8 watts, medium 20.5 watts and of course high 49 watts. We'll have to see about the sensitivity of the superheterodyne receiver as time moves on.

Welcome to the club. It’s a great radio, and performs well. I never knew that about the priority channel. I’ll keep that in mind if I turn weather alerts on as part of the scan as I also have the IC2730. Good info, thanks WRYZ926

My brother's call sign stayed the same when he went from technician to general to amateur extra. He was first licensed in 2022.

Has that recently changed? Because three years ago I was automatically assigned AI7KS after I passed the AE exam.
