I bought a pair of these just before Xmas. I did have to contact them to figure out how to turn on Channel Descriptions. They are working well. The batteries are interchangeable with the USB chargeable batteries for the Radioddity GM-30 GMRS HT; though you do have to remove a small ridge of plastic - I used nail clippers for that obvious alteration. You can us cheaper cables in Linux because Linux does not demand the specific chip WIndows is fussy about - the problem is not the chip, it is Windows.

@tomperone9338 2 года назад

I have two of these and have been quite happy with them. The 1400mAh battery was a bit smallish for my tastes, but they now offer a 3200mAh upgrade. I consider it a step up from a UV-5R for not a whole lot more money.

Hi Uncle Dave I really like this radio I have no trouble with make sure tell your viewers make sure the cable plugs in fernley until it clicks or you'll be just waste your time trying to get frequencies on 👍🌞👍

@DavidCurrie-lo9jd 5 месяцев назад

ON OF THEE BEST REVIEWS I HAVE SEEN ON A HANDHELD 2M 70CM RADIO VERY INFORMATIVE TOO THANK YOU & 73

@lyfandeth 2 года назад

Dave, any gadget with lithium batteries MUST be shipped with only ~50% charged batteries. That's also the best voltage to store them. If the batteries are not physically installed in a gadget, then they usually have to be shipped as HAZMAT as well. (Maybe these are considered as "installed" in the battery cartridge.) It gets complicated, and varies with the shipper too.

@dr2759 2 года назад

awesome info, thanks.

@joeframo3347 Год назад

Hey Dave I love this radio I love its two separate s m eter very cool radio 🌞

@lyfandeth 2 года назад

Stun/kill/activate are still used on many Part 90 radios, fwiw.

@TheNoCodeTech 2 года назад

You make some interesting points

@brianbrown4965 Год назад

a baofeng works. and manualy wide band with 3 buttons pressed and turn on. prolific works from web site. and vfo channel mod also easy

@Screamingtut 2 года назад

Dave DCS is used in the US also we have VHF Analog repeaters that have DCS codes.

@ToddHa Год назад

agreed. not sure where he's getting misinformed about DCS in the usa.

@Defcon1776 2 года назад

Looks like I'll get a pair, one for the emergency kit in the car and a backup at home.

@surfthewaves1837 2 года назад

Mr. Kessler, I stumble upon a RU-vid channel called UVB-76 The Buzzer that has been live since November of last year. Not sure what to make of it, so I thought it best to bring it to your attention. 4.625 MHz is the supposed frequency. I am very new to the Ham radio concept and I love your channel. Hopefully you could shed some light on this issue? Thank you Sir.

@MrRaphilms Год назад

Olá, ele pode ser desbloqueado para 220mhz? 73!

@nimblehealer199 2 года назад

I may order one soon Dave. 73's KO4ZCM

@Petertronic 2 года назад

Have they fixed the squelch problem that Radio Prepper reported a year ago?

@YayaOrchid Год назад

What is the phase locked step programming for the radio? Some are set to 6.25, 12.5 & 5k.

@K5NOV 2 года назад

Dave how's the filtering on this radio?

@jimpiper5297 2 года назад

So, Dave, the sample Retevis sent you was their 5W version? Might be interesting to see a test on the 10W flavor to verify the veracity of the Retevis specs. Agreed: couldn't imagine a user holding a 10W HT so the antenna is in close proximity to their noggin. At least the radio has spectral purity going for it. BTW: the way you see fire fighters (and many others who pick up an HT to communicate with) hold it horizontally or inverted is because the user thinks it looks cool. BTW, a quick check of the max power out of HTs intended for fire service yields: Harris VHF LMR 6W Moto APX 2000 P25 VHF 5W Bendix-King 5000 VHF 5W Kenwood NX-210V VHF 5W I'm going to SWAG that the commercial manufacturers design for a max power out of 5W (nominal) for battery power management (operating time on a single charge) ad because doubling power out from 5 to 10W does very little to improve how well a repeater might "hear" the HT and likely little difference if operated in "talk-around" for short-range comms.

Nice..................

@VanFlicke 2 года назад

Hi Dave, Thank you for the deep dive into this radio. I bought this radio from Retevis(via Amazon), but I can't find the correct cable to program it on their website. Could you link the vendor where you got yours? Or will any two-pin cable work? Thanks

@tomperone9338 2 года назад

Any FTDI K-type connector cable that'll work on an analog Baofeng will work on this.

@evanjones2539 2 года назад

Hi Dave.... Lots of people watch you world wide, 12.5 kHz channels and narrow deviation are the standard in Europe.. Take care GW7UNV

@lyfandeth 2 года назад

Sounds like Retivis had the radios locked down for the US market, but forgot to ask about the generic manuals.(g) Remember, it can't be advertised, marketed, or sold expressly TO the ham market without an FCC blessing.

@moenibus Год назад

Completely false and misleading comment. FCC has no authority over sales or distribution of anything. even not FCC approved devices.

@lyfandeth Год назад

@@moenibus I suggest you ask the FCC about that. For almost every radio service, including car key fobs, you'll see an FCC ID number printed on a label. If a device isn't submitted for approval, it cannot be advertised for a specific service. It gets way more complex than that. Read the Federal Communications Act of 1934, that's how the FCC was born. And given exclusive powers.
