Thoughts on Retevis license free HTs (FRS)? Helping a favorite local place upgrade their radio situation, and saw the MateTalk B4. AI noise cancelling supposed to have been trained on 100k samples. $140 for a six-pack with a charging station.

I have a pair arriving tomorrow to check out - does anyone out there have prior exposure to this model? Is the advertising realistic?

Gonna find out soon enough, but if you've heard them.. let's me know what you think 🤔

@KM7CDC Curious to see how these work out… (Might purchase some for comms use at non-ham special events…) TNX & 73

@n8dmt I might make a YouTube video sometime this weekend, but they came in yesterday and the MateTalk B4's noise canceling function seems to do the job. There is an easy on-off button on the side so if it interferes in any way one can just turn it off. One curious aspect of the technology is when using together with monitor mode, the noise floor drops to almost nothing, and it seems like I can almost make out conversations that would otherwise be muddled up in the in the noise floor.

@n8dmt I actually ordered that model in addition to a pair of RT68 FRS HTs. I have to say that the MateTalk B4 wins between the two if only because the RT model seems to not want to work beyond channel 5 with other RT 68s, or perhaps other RT models. Even when I synchronize their tones only channels one through five can talk across the different models.

@n8dmt The B4 programming cable is perpetually sold out on their website, so customizing them via a PC is not a thing right now. But the software lists a template with the default tones, so I used them to program my other FRS (and GMRS) radios, problem solved. The B4 model appears not to be locked down like the RT model is beyond channel 5. The strange thing is even with monitor mode turned on on another radio I still couldn't hear transmitting from the RT 68 on higher than #5 and vice versa.
