You don’t owe me any thanks. I literally did nothing other than reporting problems to the owner. Rich @rdunajewski is the owner and administrator. My guess is that he did something.

If all it’s doing is asking you to select a new password, I think that’s happening to all users. If the webpage is jumbled, try doing a refresh. If it’s still jumbled, report it.

TD-H3 transmitting but not showing up on SWR meter
SteveShannon replied to hxpx's question in Technical Discussion
I found this snippet in a bunch of articles on hackaday: MURDEROUS “USB-C” PSUS AT YOUR LOCAL LIDL Remember the power article, specifically, how you get to higher voltages? Let’s recap: you get 5 V first, and then only after resistor detection. Higher voltages require negotiations over a digital protocol. This is a safety rule – it’s how you can use the same USB-C charger for your laptop, your phone, your wireless headphones, your devboards and whatever else. Now, what happens when someone builds a power supply with a fixed higher-than-5 V output, say, 12 V, and puts a USB-C plug on it? The answer is – seriously bad things happen. Such a power supply isn’t safe to be used on actual USB-C devices – it’s likely to destroy your phone or laptop, and it’s at a glance indistinguishable from an adapter that follows the USB-C rules laid out for everyone else. If you must use such an adapter for something every now and then, you ought to mark its cable with red tape in a way that covers the connector plug, so that you (or your loved one) don’t grab it to charge something else. Seriously, it’s easy to make a mistake, and the more you get comfortable with USB-C, the more likely you are to make it. Who does this? Well, many no-name manufacturers do, but also Lidl Parkside tools, for one. CrowPi does this too, in their recently released CrowPi L laptop. Both of these come with dumb “USB-C” 12 V power supplies, and neither of them should be sold to consumers, especially given that the CrowPi laptop is designed for kids and educational purposes, and Parkside tools are designed for non-tech-savvy people. When your kid burns a $500 smartphone or your granddad burns his laptop due to a $2 power supply, that’s when the gravity of this standard violation really sets in. -
TD-H3 transmitting but not showing up on SWR meter

My Alinco dedicated charger tops out at 8.41 vDC once the light turns green. That’s typically considered the max charge voltage for a lithium battery (actually 4.2 vDC per cell and the 7.4 vDC battery is made up of two cells). I wonder if the issue is that it’s a usb-c charging device rather than a dedicated charger. That would rely on the internal battery circuitry to regulate the voltage because the usb-c charger has no idea how many cells are in the battery. -
Yes, we’ve been talking about it for a couple days in the section of the forum dedicated to this site.

TD-H3 transmitting but not showing up on SWR meter
SteveShannon replied to hxpx's question in Technical Discussion
That’s just about ideal. So the charger is definitely putting out 12 volts once the battery is fully charged. That seems completely wrong to me. For the example I listed earlier, the Baofeng charger displayed a green light and was putting out 8.08 vDC. The Alinco charger is still charging and it shows 8.34. When it turns green I’ll measure it again. -

That could be. When transmitting the battery will provide the necessary power but I would expect a slight voltage drop which might cause issues for the charger. -
TD-H3 transmitting but not showing up on SWR meter
SteveShannon replied to hxpx's question in Technical Discussion
Which is why I suspect a firmware issue with the charger increasing. Once the light turns green the charger should only provide the voltage necessary to maintain the battery. It shouldn’t increase the voltage that high. What does the fully charged battery voltage show when it’s out of the charger? -

That’s what I’m saying; I don’t think it’s the battery. I think your charger is pushing too high of voltage. Take the battery off the charger and then measure the voltage at the battery terminals. -

My Alinco charger with battery shows 7.93 vDC. My Baofeng shows 8.08 vDC. None of my battery chargers put out anything close to 12-15 vDC to a 7.4 volt lithium battery. -
TD-H3 transmitting but not showing up on SWR meter
SteveShannon replied to hxpx's question in Technical Discussion
It appears that your battery is in the charger while you’re measuring the voltage at the terminals that connect to the radio. I could see a firmware error (maybe even intentional but not what I would expect) in the charger increasing the charging voltage to the wrong voltage. If so, that should be a fairly obvious error that TidRadio should remedy. If that is what’s happening it could definitely let the magic smoke out of radio circuits. That would match your picture. My Alinco radio has a warning about powering on the radio while the radio and battery is on the charger. I’ll plug it in and see what voltage appears on the battery terminals while charging outside of the battery. -

I’ve never seen a battery that could be charged to twice its design voltage, but I admit I’m not an expert on all battery types. -
GMRS Radios For Rescue And Recovery In Iran
SteveShannon replied to tcp2525's topic in General Discussion
Well, we can hope…. It worked so well in Afghanistan, Iraq, Vietnam, etc. Syria was different because the U.S. wasn’t overtly involved. It stands a good chance of succeeding. -

I doubt that what’s left of their leadership will change. Nor has the U.S. shown an interest in attacking their religious leaders (and they probably shouldn’t). -
You need to clear your cache. No, I’m wrong. Although it isn’t jumbled for me, the home page is asking me to create a new password again. I’ll report it again.

I doubt anyone in Iran would ever accept any wireless devices from any country allied with Israel. -
New to GMRS world looking for advise buying first radio

I have the 805 and like it. -
Are you entering an I (eye) or a 1? The correct format is four letters and three numbers.

Welcome! I haven’t used Chirp lately, but if I were you I would binge watch Notarubicon videos on YouTube. Starting with a Baofeng isn’t a bad idea. -
I don’t think Rich gets notified unless something is reported. Everything on the home page works fine for me now and has for a few hours.

It’s working now. I didn’t reset my password.

The logic of the question was altered by the $100 limit; the logic isn’t truly scalable. I wouldn’t use pvc. It’s too flexible and it gets brittle after exposure for several years. There are chimney mounts that strap to chimneys and support a metal mast or even a fiberglass or carbon fiber mast (fiberglass is perfectly adequate and non-conductive). A decent base antenna will work well in that kind of installation.

I agree, but I think it buys more than it used to. On our road home to Butte from Phoenix this past week quite a few places were advertising for help. At convenience stores the starting wage appears to be $21.00/hour. So $100 worth of stuff is now equivalent to about five hours of work. When I was a sophomore in college (1974), I worked on a farm for $15/day and they were long days. Within a couple years I got a job at an appliance store for $1.25/hour. Compared to what my wages would have purchased then, five hours will buy a much better radio, antenna, and cable than it would have then.

Same thing. Did either of you report it to Rich? I did anyway. I think he’ll forgive me if I’m duplicating your reporting.
