"The UV-5H will be ready at the end of this month. Once the goods is ready, you will be informed.I will give the Chinese manufacturers credit. They are very good at responding to e-mails. I have always gotten a quick response from Vero Telecom - usually withing 12 business hours. That's especially good considering the time difference.
If you have any requirements for this item then, you could contact with me directly.
Hope to have a nice cooperation with you SOON.
Best regards,
Vicky Huang"

KYD NC-5H, KYD UV-5H: Availibility
Steve (K8SAR) e-mailed KYD about the availability of the UV-5H and was told it would be out at the end of July:

Baofeng UV-3R: Colors
Looks like some of the UV-3R colors are starting to become available directly at 409 Shop or via eBay.
Red
Blue
I still want a yellow one. Although these are pretty garish looking, so they might suffice.

KYD NC-5H, KYD UV-5H: Yahoo Group
That didn't take long... a Yahoo Group for the KYD NC-5H, KYD UV-5H.

Baofeng UV-3R: USB Charger
[ UPDATE and a WARNING: Luis points out that USB will only do up to 500mA. The wall charger pictured below is 1000mA. He says newer computers build in protection for this, but that he would not recommend trying this with older machines. USB power info on the Wikipedia page here. ]
Several people have said they built USB chargers for their UV-3R, so I thought I would give it a try. This worked for me, but I'm not an electronics expert, so proceed with caution - and I'm always open to suggestions/corrections.
The first thing to note is that the charger has non-standard wiring - the tip is negative and the sleeve is positive. TNJeff verified that with a meter, but it is printed on the label on my charger.
Next I cut the wire half-way between the wall wart and the plug. If you don't want to carve up your charger, you can order the 2.5 x 0.7mm plugs or even an extra charger on eBay.
After stripping the wire, I used the meter to figure out the tip was connected to the red wire and the sleeve was connected to the yellow. The opening in the tip is very small, so I had to work carefully to insert the probe and test continuity.
I took a spare USB cable and cut it in half. As you can see in the diagram below, black is ground and red is the 5V connection.
I connected USB black to plug red then USB red to plug yellow and then applied some electrical tape for my testing. (If you think the diagram below is ugly, you should see my actual cable. I'll get it dressed up and post some pictures then.) Make sure you have the USB logo on top, so that the ground is on the far left and the +5V is on the far right when you test your continuity.
You should be able to confirm continuity using your meter between the ground on the far left of the USB and the tip of the plug. Likewise, you should be able to confirm continuity between the +5V on the far right and the sleeve of the plug.
I plugged the USB connector into my laptop, inserted the plug into the UV-3R, and the radio began charging! I know this may be a super simple project for many, but I hope it is useful to someone.

A Good Week
I bought the running shoes and actually ran more than once... 3 runs for about 3 miles on average. The last run was probably the easiest despite the heat.
I went to Coal Creek today and shot about 150 rounds of 9mm in the CZ. The only good thing I have to say about that is that no one got hurt. Even a little practice makes a lot of difference. I need to figure out how to get to the range more often.

Baofeng UV-3R: Modification Loud Receive Audio
I posted a link to this modification earlier, but it was in the context of taking the rig apart, so I wanted to add this post.
There have been three consistent complaints about the UV-3R:
1. Slow scan speed
2. Spurious emissions/harmonics issue
3. Loud receive audio
OM1LD has the fix for the Loud Receive Audio.

Baofeng UV-3R: Modification Low Pass Filter - Harmonics
Leigh, WA5ZNU, tries his hand at the low pass filter modification to deal with the harmonics issue on the UV-3R:
Low Pass Filter (WA5ZNU) - Harmonics Issue
Updated:
My thoughts on the issue:
1. Many confirmed an issue existed, but there were several opinions as to the severity of the issue.
2. Even if the radio doesn't meet the letter of the law (§97.307), the real world impact of the harmonic should be negligible.
3. If using the single band antenna, the radiated signal should be even less than what was generated by the radio and measured by a meter.
4. There is a mod that eliminates the issue and improves performance, so I may try that.
Ed tells us that they are trying to get their Part 90 Certification. I wonder if that has any impact on getting this issue resolved.

A Dance with Dragons
It is almost here... another couple of weeks and I will be reading A Dance with Dragons. I've been to one of George R.R. Martin's book signings before, but I don't think I will make it to the one at Joseph-Beth Booksellers in Lexington.
On a sad note, he will not be doing personalizations:
I guess that is the price of popularity - and without it we might not have gotten the HBO series.
On a sad note, he will not be doing personalizations:
"There's one huge change from all my past signings and book tours: I will no longer be able to do personalizations. The crowds have simply gotten too big. At my huge signing last week in Ljubljana, Slovenia, I started out personally inscribing the books, as I have always done in the past, but had to cut that off about four hours into the event. If I hadn't, I might still be there, signing. The same thing happened at my last big US signing, at Vroman's in Pasadena, and for the same reasons. It takes time to write, "to Charlene, Winter is Coming" or "To Fred, All Good Wishes," and when you are writing it hundreds of times, well... it makes the lines move considerably slower. And it's not fair to personalize the books for the front of the line, and not for the poor sods waiting for hours in the back."(My copy is signed "Winter is coming.")

Baofeng UV-3R: US Re-seller - Import Communications
Some facts plus some guessing on my part...
I think Ed of wouxun.us might be setting up to sell the UV-3R.
Follow along...
On the Wouxun Yahoo Group, Ed responds to some comments about the UV-3R:
I believe that http://www.kmaantennas.com/ is Ed's original/other business. A quick whois check confirms that Ed is the owner of the Import Communications domain and that it was registered about a year ago.

Lastly, I did look and see that Ed is a member of the UV-3R Yahoo Group. This doesn't mean a lot by itself, because it would make sense for him to an eye on the competition, but I'm adding it to the pile of circumstantial evidence.
Worlds collide - Wouxun and Baofeng! It makes sense that he might setup this more generic company to sell multiple brands. I'm actually a little jealous. I thought about trying to set myself up as a re-seller, but didn't have the courage or time to really pursue it. I hope I am correct, because I think Ed will be a good guy to sell these things.

"The factory has applied for Part 90 certification, which may take about a month.So he knows the factory has applied for and hopes to have their Part 90 Certification in a month. I had not heard that anywhere else and I've been trying to keep up with any developments on this front. I tried looking for Import Communications via Google, but didn't really find anything. On a whim, I tried http://importcommunications.com/ and got the following error:
Hopefully they will be distributed in the US by a company, Import
Communications.
