dBi numbers are bigger therefore you can sell more antennas.

I was playing around with radio mobile online and notice that their calculations are off because they are using dBi numbers in dB and dBm equations. That's what prompted me to look for a calculator for µV to dBm. t They have it as (46.23-1.3+9.8+9.8-1.6)-132.0=-69.07dBm I believe it should be (46.23-1.3+7.65+7.65-1.6)-132.0=-73.37dBm

Ya, I just got the CA712EFC and the "C" is just a sticker they put on. 1st time I bought the antenna I emailed the company and they said that's the way they do it. 2nd time I ordered the antenna it was the same. No need to email the company, had already been through it.

My non output H3 would transmit for about 1/3 mile to my other H3. But it wouldn't connect to a repeater. So very likely there is output even if it's just from the oscillator in the front end and not the main power output. The radios are sensitive enough to pick up very weak signals. Just not throw them far enough for a repeater to pick them up. But ya, check your tones. With the H3 you can wirelessly clone one radio to the other. So if one works and the cloned one doesn't there is an output issue.

Ya, that can be annoying and nice at the same time. But you have to do it in the right order. If you put the tone in the RX it'll automatically put it in the TX, but you still need to go there and press the blue button to enter it. At that point if you have a split tone you can enter it, but you must put the RX tone in 1st. It you put the TX tone in 1st and then the RX it'll change the TX tone. That was just part of the learning curve on the radio.

Why are you here? You don't seem to like any radios anyone has, only have negative things to say. Do you come here to bish at people because your life is so sad?

It's not an "issue". It's the way it works. Unfortunately it's not in the manual so no one realizes it until they ask questions. It's more of a missing item in the manual.

Did the update a while ago and it was successful. I had the cable with the chip built in and the cable they sent me was just a straight USB>RJ45 no chip. I'm guessing the chip is in the repeater. So ever since I did the update it's been tough to reach my house. Today I remembered they put a squelch function in the works and I went to find it and the default is set to 6. Who sets the default that high? I dropped it to 1 and low and behold my wife can reach the shop. I've always been able to reach the house good. At 6 it was pretty sketchy and a lot of the time no audio, just the repeater courtesy tone. We'll see if it keeps working from now on or if this was just a coincidence.

Sounds like they took a nice radio and really screwed it up. I have none of those issues with the original. Worst issue is you get a dead transmit radio every once in a while, and they replace that. Ya, if you get in with them through email they will treat you right. I deal with Luxi and she hasn't lead me wrong yet. Gave me a UV26 to test and review. I like the H3 better.

What's not awesome about it? I think the TDH3 is pretty awesome for the money.

Got the tracking # for the hardline, not arriving for a week. Looks like by that time the weather might be a bit more pleasant to be out in. Below freezing tonight.

Sounds like a good setup.

Well that's different than entering the program mode for the original TDH3. It's just push the PTT and turn the unit on after you've activated the firmware update in the IAP app. We don't need to push the 1 button.

Usually with this type of hardware you can just put the previous firmware back into the machine and get it going again. It has a ROM memory that is the basis of the radio and the firmwares just update that without affecting it. So turning the radio off, push the PTT and use the previous version and it should start up again.
