Upon measuring the Power Output of the UV-3R+Pus on 223.5, I find the power is greatly reduced, On 2M and 440, I see +33dBM, which is 2W. On 223.5, I only get +12.26dBM, which is pretty lame. That come out to be 0.0168267406W, or roughly 16mW. So there must be some Filters messing with us. But I can hear it in my Kenwood TM-331A mobile rig just fine, so for short simplex it will work. Also to some repeaters where U have a good shot at it. The stock antenna is optimized for 2M & 450 so I need to score a Triband antenna so I have a chance of getting out with the 16 Milliwatts.
RX sensitivity is pretty good. Measured at -119dBM minimum discernable signal.
Measured TX frequency (223.5) 223.4988120 Mhz
So it WORKS on 222, KINDA!In a follow-up post is a link to an app that will auto-mod your .ini file to open the frequencies. He has successfully used the program with a UV-3R Mark II and a UV-3R + Plus. Head on over to Mark's (VE3PZR) page and check it out.
How to update your UV-3R Mark II to support 220mhz Ham Band
Some models of the radio are able to support a much broader range of frequencies if you store a special memory file into the radio.
Follow these steps:
[1] Install UV-X4 programming software
[2] Run the UV-3R-soft-Modder program to update your UX-X4 software to add some extended Band Plans
[3] If you have an existing memory file, re-run the soft-mod program to change the Band Plan that is embedded inside the .3R memory file.
[4] Load the memory file inside UV-X4 and write the memories to your radio and your radio will now have 220mhz added to your radio!
Tech TIP #1: If you are unable to write a memory file to your radio, power-on while holding down the VOL button. It will reset your radio back to factory and you will be able to write the extended frequency file.
Tech Tip #2: 2 memory files are included. Both files have 220mhz included but during tests with other hams, we found that my radio gave better 220mhz results if we lowered the UHF instead of raising the VHF frequency range. I suggest testing both methods with your radio to verify results.
The new file has been uploaded to the Files section and also placed on my webDownload is here. The readme file states:
site. It starts in English and does 2.5 kHz frequency entries.
This is version 2 of the programming software for the UV-5R. If installing over a previous version, you must first remove or rename the file "BF5R_CPS" from your original folder.
Improvements to this software will continue and newer versions will be announced and posted to the UV-5R Yahoo-Group and to the web site www.UV-5R.com as they are received.
73, EdThe software installed in a different path than the original version I had. YMMV. I left the radio at work, so I couldn't really test it, but it does open with the menus in English. A step (no pun intended) in the right direction!

"Looking at a scope there is no unwanted 2nd harmonic on 145 Mhz" Jaap (PD0JDG )And some notes on the power output:
"I measured mine with a Welz wattmeter and a 50 ohm dummy load. I get a little more than 5 watts on both 2 and 440." Brent (WB4SPA)
"I measured power output with digital swr/pwr meter. Maximum Power output is 4watts on both vhf and uhf. I got swr of antenna suppleid with uv5r as, 1;1.5 on 143.000mhz vhf and 1:1.5 on 475.000mhz uhf. And on all other freq swr is more than 2." Puranik (VU3KOD)And Steve (WB8GRS) has some squelch, sensitivity, and power output measurements.
03/19/12 "The TYT TH-UV3 Dual Band HT is on the way to me now. I will update everyone as soon as I receive them."So he could have the TYT TH-UV3 any day now. We do live in interesting times.
02/20/2012 "Baofeng UVD-5R Dual Band 4 watt HT was just released for sale in China. This is a nice little Dual Band rig but as of now, the menuis only in Chinese. This is howthe first UV-3R started out and then they made the english menu later. I would like to note that this radio looks exactly like the TYT F8 Radios. In talking with TYT I found out this is a COPY and not a radio made by TYT and sold to Baofeng. TYT has a patent on the case so we will see what TYT does about this later. So if you buy one of these on the internet, BEWARE, its menu is ONLY IN CHINESE and hard to figure out. I have one to test and I am having the menu translated and I will update you later on this.
Dual Band mobiles are not anywhere close to being released. I would not look for them at Dayton this year. Maybe if we are lucky, a few months after Dayton but this is just my personal guess with info I hear in talking with the MFG's every few days."
No Date "We attended the Hong Kong Electronics Fair and the Canton Export Fair Oct 15,2011
We will be updating the site in a few days with all the New Goodies we found at the show. Lots of exciting things in the works so be sure to check back with us and get updated.
We are in China now so if you have any special radios you would like us to purchase for you, contact us and we will be glad to purchase for you.
Call 405-227-9980 (Our time is opposite the USA time so when its 11 am in the US, its 11 pm in China) Please call late evening your time to reach us.
We can get you the latest versions of Wouxun,TYT, Baofeng and others at Hong Kong Prices."Pretty cool that he offers to ferry radios back from China. Shipping and wire transfers can make a good deal go bad very quickly.
11/11/2011 "Wouxun is going to raise the price effective now of the KG-UVD1p & UVD3 about $22.00 This is because of dealer requests to add 2.5 steps to those models. Its seems more like a move on Wouxun's part to increase the retail price like they have been wanting to do for sometime. They also increased the min wholesale order to 500 units. This is going to put the Wouxun HT's in a higher price class and TYT and others will have the advantage. Hong Kong will have a much lower price and attract more customers. As far as the Dual Band mobile, I would not look for it anytime soon and when it does come out, I am anxious to see the price. Wouxun is not aware of other companies working on Dual Band Radios because they pay little attention to their competition."Build your brand and demand higher prices. It is the American way!
"A lot of really good businesses build their business model around getting to 10% conversion rate to purchasers within 6 to 12 months. It’s simply amazing that we’re seeing 10% conversion to purchase within the first week for iPad users.
Second, the Custora model forecasts that iPad users are worth twice as much 2-year revenue vs. non-iPad customers."And it seems we are learning new ways to use our iPads. With all the "cloud" services, I'm surprised that the demand for more disk space is going up. Perhaps the magic of syncing across devices actually drives the need for more space when all your pictures, videos, apps, and files start showing up on your tablet. I am seriously thinking about an e-ink Kindle to use as a pure e-reader, so the second graph makes sense to me.

Members will also gain access to archived issues of QST from December 1915 to the present; previously, only issues through 2007 have been available to members. If you are familiar with the current periodicals archive, that platform will be expanded to include all of QST from December 1915 through December 2011. A second, new archive will be introduced for issues beginning January 2012, featuring enhanced functionality including full-text search."
"if any rep from baofeng monitors this site is'nt it about time you got these radio's right.after the uv-3r mk-1 then the mk-2 and the mk-3 and now the uv-5r there are still major issues.come on get it right and stop ripping your customers off and coming out with useless excuses."I'm not sure why this bothers me so much. The outrage? The grammar? The lack of specifics (relating to the "useless excuses"? The incorrect model names? The sense of entitlement? The sense of powerlessness?

1. Added 47pF missing capacitor to VHF LPF. Improved VHF 2nd harmonic
suppression by 12dB.
2. Added 0.001uF (i.e., 1nF) capacitor from PTT line to ground. Solved PTT
lock-up problem with external mic.
3. Changed R13 in path from RDA1486 transceiver chip to LM4890 AF amp chip from
10K to 33K. To reduce RX audio volume.
4. Changed R10 in path from pin 27 of MC81F8616L MCU to LM4890 AF amp chip from
100K to 1M. To reduce beep volume.
5. Added 1mm thick pad of non-woven polyester fibers between internal mic rubber
boot and front housing. To reduce mic sensitivity and to reduce wind noise.
6. Added 15K chip resistor across internal electret mic element. To reduce
internal mic sensitivity and prevent RDA1486 transceiver chip from overdriving
and limiting/distorting TX audio.
7. Built quarter-wave (i.e., 19.5 inch (495mm)) antenna from 20-gauge (0.032")
music wire. To replace unimpressive dual-band antenna that came with the radio
when I bought it used.
8. Added quarter-wave (i.e., 19.5 inch (495mm)) counterpoise of 22-gauge
stranded wire. To further improve antenna.
9. Bought Body Glove universal cell phone pouch 170-5997 (CRC91777) for $2.97
clearance price at Radio Shack. To protect and carry radio.
10. Punched holes in the cell phone pouch for internal microphone and speaker.
To be able to use radio with internal mic and speaker while in pouch.
11. Bought UltraLast UL-NP60 (230-0485) 1100mAH lithium-ion batteries for $1.97
clearance price at Radio Shack. To have extra batteries at almost no cost.
12. Used only the radio's internal charging circuit, not the external tray
charger, to charge the batteries. To ensure the radio's LTC4054 lithium-ion
battery charge controller chip is managing battery charging.
"Indeed. After years of enduring networks with servers with tree names or GI Joe character names, when it came for me to come up with names for my servers and other network devices, I came up with functional names that describe physical locations, departments, functions, and so forth. That way I have a descriptive network rather than trying to remember which one of the Power Rangers the last IT guy liked the best."And from Dave Emami we get:
"The Naming of Servers is a serious matter,
It isn't just one of your holiday games.
You may think at first I'm as mad as a hatter
When I tell you a server has three different names...
... those being DNS entry, IP, and the one which "the server itself knows, and never will confess."
