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.

Yep, mine to. But lots of sites run quick. But that does answer the question about if there is a delay. Yes, transmit stays on for predetermined time. I guess my brain was off when I was thinking about that. Not the first time, and I"m sure not the last.

Maybe the word oscillation is whats got me. Oscillation is usually internal to the repeater due to a failure. Or if the separation and isolation are not good, you can end up with a transmit loop if the input and output tone are the same. You won't have any oscillation. If you have a short tail, the repeater transmit may cut in and out as the receiver cuts in and out. I usually set mine to 2.5 seconds. You will hear the remote station drop out and come back in, but the transmit stays open. For 2.5 seconds after the last drop.

I use both amateur and GMRS bands pretty much every day. For the most part, I'm conscientious about obeying rules, but I just can't see carrying two HTs around or mounting two different radios in my car if I can get both in a single radio. If the FCC showed an interest in enforcing the type-acceptance rules, I suppose I'd feel differently. I do get a little use out of the 1.25 meter band and I like that the AR-5RM has that capability. The Baofeng K61 also has 1.25 meter capability and is a little easier to carry around due to being intermediate in size between the UV-5r and the 5RM.

Yes, we’ve been talking about it for a couple days in the section of the forum dedicated to this site.

Tidradio has their own Amazon shop which is probably why the replacement came from Amazon. Took about a week to get it to me once they sent the "replacement is on the way!" email. They're good to work with. They did ask me for pictures for their engineering team since I mentioned hooking it up to an SWR meter, but they never followed up on them.

Good to know. I would have figured that replacements would have come direct from China.

Alright, finished charging sometime after 2am, so here's the album. Battery read 8.57v both on the little single port charger and the Anker charger after being fully charged. Maybe they fixed them? I'm going to run this battery down to ~50% to replicate the condition of my first battery and then we'll charge it again to confirm. Edit: Put the old battery on the charger out of the box: 12v again. It's gotta be something with the internal charging circuit on the battery.

No,, not a Firefox fan and i never use add on's. got this one two browsers i use.

I got it

If you're on a HT you wont hit any repeaters in or around Clarksville and defiantly not in Nashville.

No. Sounds like you're using the wrong browser. Use Firefox with Ublock Origin and Ghostery Add-ons and you won't have to put up with that crap.

Anyone else getting a Password Expired Notice when reviewing the latest Repeater updates just sent? I'm getting the notice even though I am logged in. Looks a bit suspicious

Wasn't really talking about testing, but real world conditions. The conditions between my house and repeater are sort of at the fringe even though it's only 1.9 miles as way of the crow. And while walking around my neighborhood I can usually reach the repeater and transmit audio through my 5 watt HT. There are times where I can hit the repeater and get nothing, just a blank receive from the repeater for the whole transmission and then the courtesy tone. I have a courtesy tone on my repeater so I know when I hit it with absolute certainty. But I've never heard what I would consider an oscillation. This theoretical oscillation would only happen as long as the HT is keyed up.

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.

Right around 8v. The one I pulled out of the box was at 7.5v and is currently charging. Bumped up to 7.7v on the included charger. I'll test it again and post photos when it's done charging (maybe in the morning depending on when it's done).

Hmm. I'm not sure what you are describing is all that unusual. Every radio that is on the ragged edge of a repeater can cause that 'oscillation' condition if the duplexer is not tuned correctly. There really isn't anything you can do beyond a properly tuned duplexer. Now when I am testing, I do run repeaters with the receive input not connected to anything, a dummy load on the transmit side and no duplexer. I have never had a transmit signal from the repeater desense my test HT to the point where there was a failure to operate correctly. I'm not sure you can create that condition unless something is horribly wrong somewhere.

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?

Spanish for "bear"

Wonder if the Alinco warning is due to the sudden voltage dip/current draw on power up messing with the charger. Kenwood's TH-D75 manual recommends not TXing while the battery is charging because the sudden power draw causes issues: The H3 batteries charge over USB-C and I'm using an Anker charger that I've used on pretty much everything else. While the battery is charging, it only showed 7.5-8v across the terminals. Shot up to 12v as soon as the light turned green. I can try it with the little single port USB block they included with the radio if you want another data point. Lemme unpack this radio and let's see what happens (assuming the battery isn't fully charged from the factory).

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.
