Oh! No wonder I can’t find it! You mistyped: Portillo’s!!!

Sorry I didn't get a notice of a reply. Yes I plan on 2ea Antenna's. GMRS will be used trails and desert exploring. I assume since the solar panels are mounted above the alumnum roof is the reason it will not work to provide a ground plane. So..Could I add this http://Nagoya GPK-01 to gain the ability to mount on the crossbars? https://www.youtube.com/watch?v=CUV6p5nfK3c&t=191s Would the Nagoya also work for the 2m?

462.3900MHz.

I have it mounted out in the open on my fold down cup holder so it gets plenty of air flow around it. Even with it off in my enclosed truck in the blistering AZ. summer it'll be hot, everything in the truck is hot so I've never felt the need to check the temp.

Don't waste your time or money on that cable as it won't work. I have tried mono to mon splitters and mono to stereo splitters, none of them will work with a standard mono speaker. The only way to get it to work is to use a mono to stereo splitter AND a true stereo speaker (with left and right speakers). See my earlier posts above.

Where’s it located? What freq?

Does it use UV-5R batteries?

The 880-1 are nice radios.. I have two and they'll never leave my sight

gotcha ,, thought this was HT

i found this cable today on amazon, in case anyone is looking. i am about to give one a try... https://www.amazon.com/Breakout-Splitter-Adapter-Headphone-Speaker/dp/B0785VKZW4

Probably yes, but that doesn't make sense since that radio doesn't have an internal battery.

I agree with @wdrj205 start over. check what I put in the thread below to test your radio(s). This should make sure that you’ve done what you think you’ve done. https://forums.mygmrs.com/topic/10407-repeater-connection-problem/page/2/#comment-111315

I think that they meant internal to the radio. I tested it both on the DC socket in the truck and on an Ecoflow power bank with the same results (or lack thereof). It's returned and the replacement should be here tomorrow.

You mean the car battery? The GMRS20V2 is a mobile radio. There would be other symptoms with the vehicle if the battery had an internal short.

Or keep it and use it for spare parts that are common with the 880-1 version. Sometimes finding spare parts for old radios is nearly impossible. That's why a few guys keep junk chassis's around to pick over.

getting that hot, i would suspect something gone wrong with the battery.. i.e. a short ..

To limit range. FRS is intended to be used for short distances using handheld radios and no licenses. As soon as a high gain antenna is installed the range for two watts is basically the same as GMRS radios.

Definitely a problem for it to be that hot. I wouldn’t expect the voltmeter to reflect a significant voltage drop unless your battery were nearly dead. You’d have to view the current on an ammeter to see how much the radio was drawing. Let us know how the replacement works.

Simple Answer - No Suggest You Trade Or Sell The 880-2.

Have you noticed if the radio is getting to hot to hold (i.e. >130F)?

I had it connected to the Midland MXTA25 Ghost and it had an SWR of about 1.05 before the radio crashed. I'm going to get another one and give it one more try. The form factor and convenience is worth the effort.

Used an IR gun after it nearly burned my hands to confirm the actual temp. I had to wear gloves to handle it. I agree that it should not have been that hot but it was turned off but still plugged in. I was curious about the drain as well, but I did not notice any significan draw down on the volt meter on my truck. I did box it up and will exchange it today for another one. When it did work, I was very pleased with it. I was able to hit my preferred repeater in BR from my office parking lot about 25 miles away. The small size was convenient. I wasn't sure how I would like all the controls being on the mic but I eventually found that to be one of the biggest selling points for me.

A dual-band FRS/MURS radio would be extremely useful. FCC would have to change the rules to allow a detachable antenna on FRS. TBH, I don't think it's even on their priority list, so it's not going to happen, but it would be really handy. BTW, what's the reason for requiring a fixed antenna on FRS? I understand the restrictions on bandwidth and power, but not the reason for the fixed antenna.

I've had this same radio in my truck here in Arizona for well over a year and it's still working fine. I monitor the local DPS channels while I'm driving to keep track on what's happening on the roads. It gets really hot inside my truck in the summer here but(knock on wood)the radio keeps working. I really like the controls on the handset as well, I just wish it had more power. My test showed around 16 Watts, not the claimed 20 Watts but most radios I've tested never lived up to the claimed wattage.

I have the ham version of this radio. It's pretty much the archetype of a "cheap Chinese radio", and as such, quality control is very spotty. I burned out the finals on the first one by keying up for a few seconds on an antenna with a high SWR. A few seconds is all it took. However, before that happened, I used it with a Nagoya UT-72 mag mount antenna on a trip from central Oklahoma to western Missouri and had no difficulty communicating with multiple repeaters along the way. While it worked, I was perfectly satisfied with its performance and I really like the form factor and the tiny size, so I bought another one. I've been careful to check SWR on any antenna before I connect the radio and I've had no problems. It works fine on GMRS simplex and repeaters and on ham repeaters. All this is to say that it's likely you just got a lemon due to poor QC. I recommend you send it back for a refund. Whether you replace it with the same radio is up to you. You might get another one that sucks, or you might get one that works just fine. I have read an anecdotal report of the radio getting really hot while plugged in even though it wasn't turned one and another report of it getting "hot enough to scorch the desk" with heavy use, but I haven't experienced any issues with excessive heat. I really like having all the controls in the handset. I wish one of the top-tier or even mid-tier manufacturers would make one like that. There are several with detachable head units, which is better than a conventional radio, but it's not nearly as convenient as having everything in the handset. The CB radio in my truck also has everything in the handset, and it's quite convenient. It might be difficult to cram all the functionality of some of the multi-band ham radios into the handset alone, but for a GMRS or straightforward 2m/70cm unit, there's no reason it couldn't be done with a bit more quality at a reasonable price.
