Baofeng Tech: UV-2501 and UV-5001 Miklor Reviews

John has been involved with the Baofeng Tech UV-2501 and Baofeng Tech UV-5001 development. He's got a review up that covers actual power output and the new features. He also talks about the issues that do not exist in the Baofeng Tech versions of the radios:
"Early first generation models of similar radios had two audio issues.
- When changing or returning to an Active Channel, there was no audio present until the PTT or EXIT button was pressed.
- During a channel scan, a loud tone was heard when stopping on an active channel, requiring a PTT reset. (or turning off the beep tone)."
He also does a comparison of the UV-2501 and the KT-8900/JT-6188.

QYT KT-8900R: Tri-band Mobile

Good news, bad news. Good news... QYT is working on a 25W tri-band mobile. Bad news... it is 136-174 MHz, 400-480 MHz, and 240-260 MHz.









From the Making Stuff Up Department

And while I'm stirring up trouble on Twitter and posting about the Baofeng Tech UV-2501 and Baofeng Tech UV-5001, should I read anything into the fact that both radios are explicitly listed as "analog" two-way radios?

Crank up the rumor mill - the digitals must be on the way. ;)

I have no shame.

Baofeng Tech: BTECH UV-5001

And now some more details on the dual band 50W mobile Baofeng Tech UV-5001 ($149.89).




The Baofeng Tech website mentions a few key features that differentiate it from the other similar radios:
"Synchronize Display Mode
Scrambler/Inversion, DTMF, 5Tone, 2Tone, CTCSS, and DCS Calling Modes (Remote Kill/Stun Supported)
VFO Lockout
Menus, Programming, and Reset Lockout
Auto Power Off Function
Dual Watch Delay Time: Allows the receiver to stay on the secondary channel longer after incoming transmission - customize the delay up to 50 seconds; This avoids manually channel switching when you are engaged with simultaneous contacts on two frequencies"
(For those of you following along, this will look just like the features of the UV-2501 from the previous post.)

And now to the specs...

Baofeng Tech: New Mobile Radios

I'm late to the party as usual these days, so I'll keep apologizing, but continue to work under the "better late than never philosophy."

Baofeng Tech announced two new mobile radios more than a week ago:
"We're excited to unveil the UV-2501 and UV-5001 Dual Band Mobile Radios. We have spent the last several months refining our first mobile radio release. The UV-2501 is a Mini Mobile VHF/UHF radio capable of 25 Watts Output. The UV-5001 is a full-size Mobile VHF/UHF radio capable of 50 Watts Output.
These may look similar in appearance to other radios, but we have re-built our mobiles from the ground up with a new menu system, audio and bug fixes, exclusive enhancements, and much more - with insight and improvements given to us from amateurs nationwide."


The similar radios are the JT-6188 and KT8900 that I've posted about. I like the naming of these - I'm a simple man, so UHF-VHF-50 Watt, version 01 makes sense to me for the UV-5001.

Leixen VV-898SP: Tokmate Version

Lyle points out that the VV-898SP Manpack is available on Amazon as a Tokmate VV-898S for $219 including the antenna and USB programming cable.

And why do I always feel like these notes are directed at me:
"The housing is detachable and the radio can be used alone, but the user must not take the radio apart, otherwise he/she should bear the relevant responsibility"

Kindle Book Cyber Monday Sale

I'm going to pick up a couple of cheap Kindle books from the Cyber Monday sale at Amazon.

I've never read any of the Fafhrd and the Gray Mouser series by Fritz Leiber, so I'm going to get the first one: Swords and Deviltry. I'm also gonna try Bruce Sterling's Schismatrix Plus. Both are just $1.99.

Baofeng UV-82HP: Cyber Monday Deal

I missed the Black Friday sale, but you can get the Baofeng UV-82HP for $48 between 11:40am (Eastern) and 2:40pm (Eastern) today. That price saves you about $17.

Grab one or two, so your tree can start to look a little like this.
