Xiegu X1M: Platinum Edition Update

Some more about the Xiegu X1M Platinum Edition on the HelloCQ.net forum. Images are via the forum and text is via the forum by way of Google Translate.
X1M Platinum Edition (Overseas customized), is in the country X1M version, based on the appearance of the display, buttons, part of the circuit is optimized for a version, mainly to comply with EU mandatory technical requirements of relevant laws and regulations, as well as relevant FCC requirements.

The improved version of the following areas:

1, for a chip with a new, lower numerical part of the receiver;
2, for a solid OLED screen, to meet the sun observation, as well as the use of cold regions;
3, the replacement of the button improved touch feel;
4, significantly reducing the use of plug-ins that will replace most of the capacitor chip capacitors;
5, will be replaced by a capacitor LPF section COG chip capacitors, filter characteristics significantly improved;
6, the power amplifier section redesigned, converted to all-MOS amplifier, all using Mitsubishi RF power transistors, high gain RF specifications can be protected, each section were 4.5W maximum power over part of the band reaches 6.5W;
7, the control software for the rewritten and revised the CW portion of the bug, is zoned separation standards;
8, carried out on the machine EMC focus rectification, effectively inhibited the machine's various crosstalk;
9, to meet the requirements of domestic and foreign regulations and inspection machine, the software inside, on the amateur bands made ​​shield band emission (in the Project menu to open);
10, to increase the reliability of keys, key board uses a PCB gold plating.

To meet the needs of my friends and thank you for your continued support and concern that this X1M Platinum Edition Domestic sales are as follows: Price: 1180 yuan / Taiwan (only mainland China and Hong Kong, Macao and Taiwan) including a full : Host a microphone in hand a power plug a 3.5 key plug an updated record: 2013.07.17: X1M Platinum Edition Quick Start Guide first release

Rotary Encoder

I got the rotary encoder in the mail today. Now, I need to carve out a little time to see if I can fix this thing.


KYD NC-UV90A: Dual Band Mobile Update Update

The previous update was "The price is not yet fixed now, but it will be around USD230. The item will be ready at the beginning of April. Right now it is under double testing and will start sample order later soon."

The new update is:
"As to the NC-UV90A, it will be available soon. Right now it is under final testing, and will get to production soon, maybe early of August. 
The price for it now is USD198. Hope it is workable for you."


Dead Man's Switch

Schneier points out that is works both ways for Snowden:
"I'm not sure he's thought this through, though. I would be more worried that someone would kill me in order to get the documents released than I would be that someone would kill me to prevent the documents from being released. Any real-world situation involves multiple adversaries, and it's important to keep all of them in mind when designing a security system."

TDXOne TD-Q8AH:

Via Nate... a followup on the TD-Q8AH.

The guy doing the video doesn't like it. And the batteries aren't compatible with the UV-5R.

American Girl Doll

And this is why I buy inexpensive radios... my daughter at the American Girl store. The dolls alone cost about the same as three Baofengs. And then there are the clothes and accessories - like a sailboat. (Luckily, we only got the doll and her grandparents are subsidizing this one.)

She got the doll on Saturday and basically has not put it down for three days. Even in full tightwad curmudgeon mode, I have to admit it is already money well spent.

So I got this in the mail yesterday after renewing my ARRL membership.


And I already had this. I've had it so long that it covers the old question set.


Maybe it is time for me to start studying.
