#6658 Boafeng GMRS-V1

Posted by WQYA707 on 19 November 2016 - 10:04 AM

I have two of these radios and have done some preliminary testing. I am a ham operator, and a member of our local ARES/RACES and NET/CERT organizations.

 

Baofeng has taken their UV82 radio and repurposed it for GMRS use. UV82 accessories, including the high capacity battery and AA battery pack, all work with the GMRS-V1. The radios are pre-programmed for the GMRS/FRS and GMRS repeater frequencies, with the repeater offset already set.  The radio will also scan the ham VHF/UHF bands (there are approximately 100 channels available), has a FM radio, dual watch and the rest of the UV82 and UV82HP features. Advertised power is 1W/5W.  The radio is programmable through the keypad and CHIRP; I highly recommend the latter. 

 

Before testing the radios, I cloned one using CHIRP, and made some modifications, including adding the VHF/UHF emergency communications channels for my area. Note that the pre-programmed GMRS frequencies/offsets can not be changed and the radio cannot be programmed to transmit on any other channels.  The GRMS PL tones, channel names, power level, and scanner inclusion can be programmed. Programming is straightforward, as is cloning a CHIRP image from radio to radio.

 

In my test rig, I used an inline power and SWR meter and tested the units with both the stock antenna and a J Pole that that I with my VHF/UHF rig. 

 

VHF power: 2W/5.4W,  SWR (with J pole): 1.1 to 1.5 across the band

UHF power 1.75W/5W, SWR (with J pole)  1.1 to 1.7 across the band

 

Using the stock antenna, low power performance in an treed, hilly urban environment is, as expected, less than a mile. High power performance was between one and two miles. I need to do more testing, with a j pole and a whip antenna to get better numbers. I don't have a local repeater to test against. YMMV.

 

The audio is clear and undistorted. Features like dual-watch, two line display, transmit timer and scanning are handy to have, especially if you are used to using them on a ham HT.  If you have UV82 equipment, the ability to swap batteries, antennas and the like is terrific.  Scanning, like on all Baofengs, is usable but not fast and when scanning, the two line display does not stay synchronized.

 

What I really like about these radios, other than 5W, interoperability with the UV82 and FCC compliance, is they can be set up, the keypad locked so the unit can't be accidentally reprogrammed, and handed to someone without a lot of experience.  I am looking at them for NET/CERT team use and they will certainly become part of my family go bag.  And for less than sixty bucks, including charger, microphone and battery, they are a real deal.

#7330 How to get pesky disrupter off air?

Posted by quarterwave on 11 April 2017 - 11:54 AM

A couple of years ago there was a Doctors office near me that was using GMRS. I set my simplex repeater on that frequency and PL for a few days...after that, never heard them again. I guess having to hear themselves repeated back all day was annoying! Imagine that.

#7300 New to GMRS. Setting Up a UHF Repeater

Posted by quarterwave on 04 April 2017 - 10:21 AM

I ditto on turning the power down. 20/25 will do as well as 40 in most cases, as the higher the tx power the more chance of drowning your input, even with dupexor (unless you are spending $3,000 on it, and even then I have turned them down to necessary power only. 

 

When I worked for M we had a customer that used a 25 watt mobile for 2 way and phone interconnect, and 2 HT600 portables, but her repeater antenna was on a 500 foot tower she owned. We had the repeater all rigged up blowing A/C directly into it, as she liked to use that phone for 20-30 minutes at a time, and it was an R100 repeater! We had it set down to get about 2 watts out the antenna, and it had great coverage, more than she needed.

 

Input path to the repeater will determine the usability in most cases not power out. Too many guys have CB mentality, not what you need.

#6844 Boafeng GMRS-V1

Posted by a0008550 on 27 December 2016 - 09:47 AM

I got mine in late November and have used it occasionally.  No problems so far.  One thing I noticed is how quick the stock battery charges - 2.5 hrs. 8.2 volts.  I left it on (scanning) for several days before it needed recharging.  I put up a quick and very 'amateur' Youtube video up on Nov. 25.  I'll probably do another video later when I get a better cam.

#6835 Boafeng GMRS-V1

Posted by Dahwg on 26 December 2016 - 09:58 AM

I've spent the last 2-3 days playing with the V1 I just received.  I don't have equipment to test the actual wattage this thing is putting out, it does have an option of selecting Hi/Low power on a per-channel basis, and the simplex channels are all set to low power by default whereas the duplex channels are set to High. There is however, nowhere in the manual nor on the radio itself that specifies what High TX power vs Low TX Power actually is.  That said:

 

I found the build quality to be far superior to a typical bubble pack radio, however short of the ICOMS I own (F21GM and F4TR1) and the Motorolas I used back in my days as a paramedic (Big bricks that could be thrown, full force against a brick wall and still keep going).  Overall I think this thing could take the beating of normal wear and tear, but I doubt that it would stand up to hard core duty on a daily basis.  Still for ~$55 it's hard to beat.  

 

Simplex transmission is clear and loud on the receiving end, the supplied rubber  duck is good enough, but I swapped it out with a Nagoya 701C and the difference was undeniably noticeable.   In fact, with the 701C, I was hitting a distant repeater much more consistently and on the RX side, I was receiving weaker signals than I was able to do with my ICOMS which ARE 5 watt radios IIRC.  I don't know if it is the wattage or the fact that the 701C is tuned better than the antennas on my ICOMs, and in the end I can't tell you if this is legitimately a 2 or a 5 watt radio, but I would be just as comfortable talking through one of these in an emergency as I would my ICOMs.

 

Programming from the keypad is not difficult, but getting the programming cable and doing it via chirp would probably be easier.  Everything is selectable and modifiable except that you can only TX on the GMRS frequencies. Tones can be programmed directly from the keypad and you can program additional channels VHF and UHF bands for scan-only operation. The one problem I had is that I could not program my local NOAA weather channel.  I can switch to VFO mode and enter the frequency and receive the signal, but when it came time to saving the frequency to a channel, it would not do it.  Any other frequency seems to save without a problem except for that one.  

 

I haven't had it long enough to comment on battery life but they do take the larger BL-8L 3600 mah battery that you can get for the uv-82 HP's

 

One thing that surprised me was how compact this radio is.  It is tiny and I am seriously considering the larger battery just to make the thing more substantial.   

 

Hope that helps.  I'd be glad to update this later with more info if anyone is interested.  I know there was a lot of curiosity about these radios.  For the price of a pair of bubble packs, this radio has been a real pleasure to use so far.

Trust me, 5 measly watts isn't going to make any practical difference in performance. If 45 watts won't work well, neither will 50 watts. :lol:

#8525 Family use of callsigns.

Posted by Jones on 12 November 2017 - 06:06 PM

My family uses unit numbers, but not very often. Names work just as good.

 

In my family; my wife and I, and our oldest son are all hams.  Our 2 younger sons are not hams. (yet)

 

What's funny is that our youngest son takes this GMRS identification business more seriously than any of the rest of us.  I will call him on GMRS as: "Hey Mike, it's Dad, copy?"  He will respond with: "This is WQYM-Five Four One, unit 5 to unit 1, go ahead Dad."

#6965 Need help getting started!

Posted by Corey on 24 January 2017 - 07:46 AM

Hello,

 

1. Type of radio would be the first thing we need to know.

 

2. Do you have the proper PL or DPL to access the repeater you are trying to connect to?

 

3. Just because you can hear people does not mean you can talk to them, if they are on a repeater and using PL or DPL nobody is going to hear you if your radio is not set up properly.

 

I will try to explain it as simple as I can and I will use the GMRS channel 462.675 with a PL of 141.3.

 

You need to transmit (TX) on frequency 467.675 using the PL 141.3 and receive (RX) on the frequency 462.675 using the PL 141.3

 

The repeater is listening on the 5 MHz + offset and almost all require a PL or DPL to bring up the repeater. If you don't bring up the repeater nobody is going to hear you because you are transmitting on a repeater input channel.

 

If you want to try and communicate with them simplex (without a repeater) you would need to use your talk around feature or set a channel up so your RX and TX info is the same but you would still need to know the PL or DPL in use by the other party.

#6474 Simplex communications on Repeater Input frequencies???

Posted by PastorGary on 26 October 2016 - 02:51 AM

47CFR95.29(b ): 

 

(b ) For a mobile station, control station, or fixed station operated in the duplex mode, the following 467 MHz channels may be used only to transmit communications through a repeater station and for remotely controlling a repeater station. The licensee of the GMRS system must select the transmitting channels or channel pairs [see §95.7(a) of this part] for the stations operated in the duplex mode, from the following 467 MHz channels:  467.5500, 467.5750, 467.6000, 467.6250, 467.6500, 467.6750, 467.7000 and 467.7250.

 

___________________________________________________________

 

As JWilkers mentioned above, there are no provisions in the Rules for simplex operation on these 467 mhz. frequencies.  If someone were to operate simplex on these frequencies, there could be a high interference possibility to repeaters operating in the area and that is why the Rule is in place.  

 

Review 47CFR95.7 for additional details concerning interference.

#6377 Ham Frequencies set to transmit but no license

Posted by n4gix on 13 October 2016 - 04:57 PM

Um, <raises hand shyly) I have to admit that I have on occasion mistakenly given out my GMRS call on 2m/70cm repeaters and vice-versa, but have always caught myself and made an immediate correction.

 

When you have so many mics to choose from it's entirely possible to pick up the wrong one. :ph34r:

Well I took the Technician test on Saturday and passed.  So something this week I expect to receive my license and callsign.  They talked me in to sitting for the General test (there was no fee for testing at this location).  Missed a few too many on that one.  LOL.  I'll most likely take it next month since I was pretty close to passing it.

#5595 Repeater to be installed.

Posted by zap on 12 April 2016 - 10:53 PM

a 10 watt repeater at 100 feet, is 10X better than a 100 watt repeater at only 10 feet. Height is King.

Line of sight. UHF in the 460 range is roughly LOS range plus 5-10%.

Money is better spent on receivers, antennas and location versus power amplifiers.

Coming from a guy who's shooting 500 mW 19 miles at 5.5 GHz and still delivering 60 Mbps over it…

#4940 Rebuilding the Chain O' Lakes Repeater - Ingleside IL

Posted by Corey on 23 January 2016 - 11:32 AM

Due to the duplexer failing I decided over the winter months I would rebuild the Chain O' Lakes repeater in Ingleside IL. I had a spare 100W MTR2000 in the garage and decided this was going to be the heart of the new machine. Tuning it down to 50W would insure a solid 100% duty cycle and provide years of service. Due to past bad experiences with EBay duplexers I decided to purchase a new one and settled on an EMR 4 cavity pass / reject with a factory tune. Being a tinkerer that loves to build things I decided to dig out all the radio junk and see what I could come up with. The finished system will have an on board Bird 43 SWR / power meter and one of those micro mobile UHF radios for testing , monitoring and local use. To limit loss and interference I plumbed the entire system with ¼ helix superflex trimmed to critical lengths. Over the past several months I was having issues with another systme on .550 so come spring it will be moving to .725. I am still waiting on a few more items to finish this build and will keep this thread updated.
