I read some questions and answers on that radio. One of the answers said the 5W
version covered 220 for transmit, and the 8W version did not (see below). Which
version do you have? (I'm not convinced the 8W doesn't cover 220 MHz though in
any case.)

--------------------------------------------------------------------------------------------
Question:
Is this a tri band?
Answer:
The 8 watt version is not tri band. The 5 watt radio is tri band.
-------------------------------------------------------------------------------------------

The specs appear to be confusing, though. The Baofeng site says it has 8W
output, so the Q&A above may not be correct in the answer. I think the Amazon
listing had 3 power levels listed, and the official site said it only has 1W and
8W settings for output power.

The Amazon listing is in the Baofeng store and it's a great price if it really
is a tri-band and has an 8W output. I wonder how long the battery lasts at 8
watts with normal conversation?

I'd get it for the 8W output if my UV-5R batteries fit it. I have two extended
life battery packs I bought with mine and the seller credited me for the small
battery that comes with it when I made the purchase.

It's strange that Baofeng's listing on Amazon is different than on their web
site. Maybe the plus and regular (non-plus) versions are different and that's
what's causing the confusion?

UV-S9 on 220

 

It programs fine and works as it should on 2M & 440, but even though the offset is showing in CHIRP, and the display shows the +-, the radio doesn't shift transmit to the offset on 220. ? Has anyone else run into this problem with the UV-S9?? Solutions?

Baofeng are good budget radios, but their claims are ridiculous. This one also is so wrong on many fronts.

-The radio claims on the front it is "digital mobile radio" when it is FM and says so below it. A big contradiction.

-Also claims to be a "dual band FM transciever" when it is tri-band.

-Ridiculous TX power claims, not one of these radios ever gets over 6 watts.


Read thru the BS and the Chinglish and watch a few reviews on youtube and you will find out what they really are.

Don't believe the wattage claims from sellers. Some add up the wattage for each
band, including low and high output settings, put them all together for a
whopping claim of big output power.

If you live in an area where there are repeaters close by, a handheld can be
useful. Here, not so much. I can stand in one place on my city lot and hit one
of the local repeaters a bit noisy. Move off a few feet and I can't maintain the
link.

Mobile with 25W or more I can hit both regularly used FM repeaters in most
places around here. There's one dead area along a long hill to the west of here.
Once out from the shadow of that hill, I can hit it again. I haven't tried with
the 50W on 2M I have available now but I could probably be noisy into the
repeater along the base of that hill. From home, with the 25W, I can make it
into the repeaters. That's into either a dual-band J-pole or my tri-band mobile
antenna.

When I bought my UV-5R (no longer sold as it didn't meet FCC requirements to
prevent out of band operation), I got two of the extended life batteries and
they gave me credit for the smaller one that came with it.

I also have the BF-888 which also shouldn't have been sold in the US but I put
it on the 440 MHz band and added some family radio service channels to it also.
It's actually higher wattage than allowed on the FRS band but I have never used
it there. I consider it for an emergency on those channels.

You'll want to get good at programming it from the front panel or get a good
cable with the FDTI chipset (not the Prolific chipset) from the Baofeng people
and download CHIRP onto a Windows PC. I think it may work under Linux also using
WINE or Crossover.

It's easy to program frequencies using CHIRP. I never got the hang of manually
programming repeaters into the radio I have. CHIRP is free. The cable is not,
and I recommend NOT buying the cheapest cable. Look at the reviews, find one
with an FDTI chipset, and preferably buy from BTech USA (I think that's the
name) which is Baofeng's US distributor. They're on Amazon.

There's a group here called CHIRP that can help you if you need help. Once you
get a good cable (not all will work well), the hardest thing is working out the
COM port used by the driver and radio and how the programming works.

Re: Failure to Transmit Problem Fixed

 

Hello Lee
Would you please suggest 1 or 2 references/web-links for modifying the BaoFeng UV-5R to be used as a fox hunt transmitter?
Thank you.


Re: Basic Unit Selection

 

There’s also a really nice device by TIDRADIO: the BL-1 Bluetooth programmer!

They are available through Amazon for $19.99.

I don’t recommend using it to program you entire radio as it can be very time consuming. But it works great to program a couple of channels or modify channel mistakes/changes. It will also hold several program downloads. Have no idea how many it will hold, but I have several scans on mine.

You can use it with Android or Apple device and you do NOT need a cable!

Just my 2 cents worth.

years ago and got it with two of the extended batteries (they let me

If you're not in a flat area or nor near a repeater, it may not be

one with the FDTI chipset. There are counterfeit cables with the
Prolific chipset and the driver will refuse to work with a counterfeit
cable in at least some cases. There's a third chipset that I forgot
what it's called and it will work, but finding the driver for it was
not easy. I have an "octopus" cable that has 8 or so different ends to
fit various radios, and I bought it just to see if it works. Other
then the difficulty of finding the right driver for it, it DOES
actually work, so I can program several brands of radios with it.

You can also get non-free software from RT Systems. You can get a good
cable from them and also great software, but CHIRP is good enough and
will save you money. Figure about $50 for the cable and software from
them. Figure less than $20 for the official cable, less for one that
works but isn't the official one (check Amazon reviews first as some
are a waste of money), and CHIRP software is free.

There are other Chinese radio HTs but Baofeng is probably the most
popular and least problematic. Don't try to save a few $$$ and buy
another brand. The Baofengs are already pretty cheap anyway. I won a
different Chinese brand of HT at our local hamfest and after finding a
cable for it, was unable to program it. I sold it for $5 at the next
year's hamfest, which is about 1/2 what I paid for the cable. It was a
waste of money to have even bought the cable! (Yes, I did tell the
buyer my negative experience.)

I use one for around the house or walking around the local district, as I am talking and listening to things close. The unit is small and will fit into your top pocket easily with the standard battery. The high capacity battery can be handy if you are going out all day and will be using it alot. The big battery doubles the size of the unit and weight.

I don't think you will be disappointed.

Listening, looking around, reading umpteen reviews, and having an old vet budget and too many interests, I agree with some which relate that the Baofeng is a good low priced entry level device for those entering amateur radio. I've been all around in electronics and communication and listened to my old military receiver.

But I am having trouble identifying which unit is preferable. I see only an odd unit with almost unused (in the US,) and a unit with a larger battery, (which I love,) and a dual-power level, which I will like, once I am licensed.

This site shows some unit examples.

I would receive traffic, and I would then press the PTT to respond. But after releasing the PTT, there was absolute silence. Only after pressing the squelch or [EXIT] key would the radio receive traffic again.

I decided that the radio's receive circuitry was being overloaded by my transmitting so closely to the radio. I'm thinking the stock whip antenna is better designed to eliminate this?

Re: UV-5R: Charge and Use at Same Time?

 

> A Lion charger will start charging at a defined current, then when the battery voltage reaches a certain level, it will charge in pulse cycles, adding charge, then observing the voltage. ?When the voltage reaches the correct level, it stops charging altogether.
Bill

Welllll... This may best meet the rule, Read the whole danged manual." But a radio tech for any business or agency ought to go a step further and absolutely confirm charging details.

An exception is my phone.
It checks battery levels before charging. It can charge at at least 3 voltages and varying currents.

With FLA, (flooded lead acid) you can see charging current drop of with an old school charger as the battery fills and "resists" input. When low, my charger offers almost 10v and almost 2A,.if my oh is off or on standby. If I attempt to use my ph, I accomodates me but V drops to 5 & change, and current to ~0.9 then smoothly drops diwn, 0.5> 0.017A etc & to 0.000. Current drops at it nears full.

So any absolute charging rule, as technology advances, is a risk. Manual are detail-poor as ~"noone really reads them or cares."

I do have a few pics of charging rate graphs I can dig up, soon, I think.

I got a cute (useful for anal-nerds,) toy from OReilly's Auto for $10 to montior a ph charger's output. They seem to have quit selling them but are on the 'net for $7-8. Big pretty blue and red LED readouts. Reading the dropping A, you know your ph is filling well or about full.

For the same price there's one with smaller text which also tells each ma and accumulates a total. You can see if your battery is still virile or getting tired. (Used sales generally attest to "at least 80% capacity.")

I use the simple on in my car w big bright letters and the detailed unit at home. Great gifts! Plug them into your USB charger and your cord into it, thus, no matter if your ph is USBC or iPh, et al.

Baofeng is a portable, so I'll mention my phf is? DooGee S96Pro.
Protection Grade:?IP68 / IP69K/ MTL-810G, waterproof, dustproof, shockproof, high & low temperature resistance.

IOW, heavy w a BIG battery, seriously ruggedized, video 15 ft down, B&W nite vision camera. Good for outdoor types. It's not 100% ideal software but neither is a $500 ph that fails after it's 3rd splashdown. Has a spot for a wrist lanyard, incl. Joke is, to avoid black eyes when reading in bed. I think it's so you don't drop?it so it doesn't exceed 15 ft when swimming in a lake, but it could also be for use as a weapon.

$199-350. 2 types, so match your PSP, (carrier.) I use Metro/TMobile, (NON-CDMA.) Was Spanish - became Chinese. Cord chg or wireless. Wireless chgr not incl, but a fast chgr is.

Good info on amazon, but price spread is huge. Be neat if OtterBox made a waterproof cover for the Bao's. This ph got a cheap clear cover as one is NOT really needed.

Mmm, it seems.my batyery charging rate graphs were in my costly ph. Too bad. Note also, Lithium batyeries are changing, va doping with Fe, for example. Voltage and overcharge forgiveness changes, as can charge and discharge rates... so an old lower V charger may nearly fill a new battery, but visa versa could cause a fire. Just a vague rule of thumb upon which you must not rely. Check, and re-confirm IF & before jury rigging a charger.

The chargers are, by design, made to trickle charge the the batteries. This keeps the batteries from overheating when charging, thus prolonging their life span.?

The chargers are designed to only produce a small current level to do this and thus stop charging if this level is exceeded.?

I keep telling our folks in the court house, and every other County agency with portable radios, who use their radios to communicate emergency situations, should they arise, between the Sheriff personnel and all the Courthouse personnel.?

They tell me that they won’t remember to turn OFF the radio when on the charger or to remove the radio from the charger when the radio is ON!

I tell them that they “CAN” leave it in to listen to the radio, BUT the radio will NOT work if they NEED to use it because it does NOT charge while it‘s in the charger!

It’s a “LIFE SAFETY” issue; ?“ YOUR CHOICE”!!

But they still do it!

So to directly answer your question: ?YES, the manual is correct! ?Do NOT try to operate your radio while is connected to a charger! ?It won’t charge the radio AND it could damage your charging device as well!

HOWEVER, ?they do make a “Battery Eliminator” which allows you to use your portable radio in a mobile configuration and they work great!

? The manual says don't charge the radio and use it at the same time. Is that really true? What is anyone's experience with this? I ran the radio with APRS and charging it at the same time yesterday and did not notice anything detrimental to its operation.Thanks in advance.
