I've swapped connectors on an AN/PRC-148. I can't imagine it's that much more involved. Remove whatever is connected to the pins then loosen the mechanical locking device. From what I see inside my Harris stuff it looks the same.

Dang, I looked these up on aliexpress and they are kind of pricey. A bit over 300.00 for just the radio, and another 100 or so for the remote.

I have no idea where the actual fountain of radio is. I've gotten closer but, have no clue.

That's because they were invented for the specwargear hong kong gucci airsofter. They wanted the look, at minimal performance. They definitely got what they asked for. Since then, people have consistently confused them with the real steel versions and amazingly enough, got some innovations done. I still can't recommend any of them outside of a few use cases. But they are unique if you collect radios, or have an emotional tie, or are looking for a particular 'look'. |

I don't intend to do a "drive by" as the canadian suggested, I have helped a lot of people fix their radios and provide answers but obviously I'm new on this forum so I understand the reaction to a degree. I've been trying to get ahold of the ultra-elusive programming software for the TRI-148 also and if I ever succeed I will share that with everyone along with the pin layout for the USB programming cable. I can reverse engineer the pin-out but of course this would require one of the lucky few who have the Monda USB stick to share the software files.

I've been using both since the first release of the plastic TRI-152, my friends & I got 4 of the originals, since then we have owned at least a couple of all the rest except the FCS. The 148 definitely has it's flaws, the antenna connectors have a tendency to fall off (hence my repair guide) and they're picky with external PTTs but when they work they're amazing. We've used numerous of the TCA first gen & current gen 152's as well as the TCA 148. TRI first gen plastic as mentioned, second gen metal, and third gen 152's with KDUs, plus of course the TRI 148 in both 6 & 10 pin variety. We also had a Toysoldier 148 back in the day which was hot junk. Message split because "New accounts are limited to 2,000 characters per post" |

We've found the best performance in field from the TRI-148 and the TRI metal 15w 152s. They achieve the longest broadcast range by a noticeable margin over the others even when running in lower power, we have tested them from miles away in forested and mountainous terrain on numerous occasions & they outperformed even expensive ICOM manpacks with higher wattage much to the owners chagrin. The antenna is very important to get top performance, the real thales 30-512mhz and 136-174mhz both work great, and the oldschool CAG green tips in 400-470mhz are phenomenal on the repro radios.
The TCAs are good and have a much better clarity of sound when receiving transmissions, sometimes the TRI will receive a garbled transmission while the TCA's is clear, but then the TCA cannot transmit a response while the TRI can. The TCA's also play nicer with genuine PTTs & headsets in my experience. I'm sure most of this has been discussed here already but it's another perspective from someone who has experienced most of the options out there and been able to directly compare them. |

Yes, that's correct. I wasn't able to find a dual watch setting in the menu options or documentation on how to disable it like.
-- EDIT -- And just so we're clear... I do not want or need this functionality. The longer I try to find a solution, the more this looks like a glitch vs a feature involving the firmware. |

Do any of you know how to disable this? You can't, it's a flaw in the newer models. If you only want to receive on one channel you have to set both to the same frequency. If you want dual receive it will be always on while they are programmed. If you want single receive, but the ability to switch channels, your best option is to pre-program them and save them as named channels then manually swap between them. This is one reason to avoid the newer TRI 152's despite their reasonably good performance and prefer the TRI 148 or TCA 152. Although as I stated before the 15w TRI-152s have great performance even when running on lower wattage (as W does not = range as discussed previously), so it's a trade off you have to make your own decision about. |

I am arguing with them now in that room.
Apparently, it does unlock the unit to be on low band frequencies. The problem is, the person that is verifying this behavior believes that whatever the wattmeter says is what is coming out on the frequency on the radio. This is a problem. |

Also, may work on the previous generation. Correct, it only works on the very latest model. You have to download the programming software to do it, the software is locked. Passwords for the software & parameter adjustment are: 11882 and 288288 Whether the radio performs well in those frequencies, well that's a matter that needs to be tested. I can't offer a definitive answer. |

the 12 dollar qs one is 13-1300, with old cell cut out. The problem right now is that it doesn't put enough out on frequency outside of 2m & 440 and what it does put out is trashy.
I know josh is working on an older TCA model, and I think some others are too, but I am not privy to any of it. I want low band also and inexpensively. I feel pretty good it's getting closer |

The FB, TRI/TCA radio Mbitr owners group has a discussion on the unlocked TCA and one of the guys is saying:
"I just tested 70mhz, and there's harmonics on 140, 210, 280, 350 etc etc. No such issue with the official tx frequencies ..." There is some questions on if the chip was actually designed for the unlocked frequencises or if it is just "able" to do them. Also thanks to this thread I contacted ShiQing and have a TCA ordered, its been awhile since I broke out the tech license and I had forgotten how damn expensive the radio hobby is. |

I am going to use the context clues you gave and asume that it is grossly oversized for what I had in mind. I liked the way it looked, for some reason I was assuming it was around 1x16 or so in size.

It depends on where you're gonna carry the radio and antenna, how efficient you want the antenna to be, and what frequencies you want to be on. If you only want to be on one frequency, and stay close to people, and leave it in a pouch, you can get away with a really tiny antenna. If you want to use all the frequencies in the radio, the antenna starts getting bigger. The biggest one is made essentially from a tape measure, and it behaves like one. They make a tampon tube looking one on a gooseneck, but most of them perform like shit. This right here is about the cream of the crop in all the checkboxes I said above: https://www.ebay.com/itm/235080986067?itmmeta=01HV5WZ8RT52EZ7TRZQCDWXPC8&hash=item36bbeb2dd3:g:b5gAAOSw~mRkqH1D |

Can we get a mid-2024 update? Are there any new releases as of 4/2024? Which is now the more capable, feature-packed model?
Thanks! |

I'm going to give it a try and we will see how it works compared to the stock antenna, at least it's a real harris. |

When I ordered from Shiqing I asked for the newest model and he said that is what they are sending. Whenever it arrives I will look and see what the manufacture date is on the back; the FB groups havent mentioned a newer one yet so I am expecting the 2023 model. |

I know it would be some work but I would think a guy could come up with a pin diode switched SMT based harmonic stripline filter network to place in the RF path right after the TX amp on a Quansheng or one of the 152 things being discussed. The quansheng would likely be way too small but there should be room in a 152 variant. Figuring out how to flag for frequency range switching would be another challenge. Some of the custom firmware might be able to spit out the current freq data for a microcontroller to monitor and act on. Basically, that's what the inside of a real deal MBITR seems to do with the entire inner side of one RF deck arranged in lines of switched filters with an Atmel microcontroller managing it all. The XG100M appears similar as well with filter networks branching out both the RX paths and also from the various RF amp blocks, switched with PIN diodes and RF switching QFN packages. I have a demilled but RF section intact XG100M RF board and a DER-EE meter and 0-1500 MHz specan with tracking gen. If I had time it would be fun to try to model something similar, maybe starting with 29-54 to see what could be achieved using a 5K HT as the DUT. I've used the specan to sweep and adjust a Syntor X9000 RF deck to bring up the 50 MHz end and regain about 20 watts output, similar overall concept.
