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.

Vichy DM4070 LCR Meter

I posted about the Leixen Frequency Counter and asked if anyone was using inexpensive Chinese bench equipment? PA1SBM posted that he got a new toy in the shack - an LCR meter.

Best Chinese Dual-Band HT

Hans says with 100% absolute certainty that the answer to the question, "What's the best Chinese dual-band HT?" is:

It depends.

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.

Extra

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.

Leixen VV-808: Popping Issue Fixed

Eileen sent me an unprompted follow-up e-mail on the popping issue - which, to me, is a good sign that they want to provide high quality products and fix any issues that are discovered in the field. Here is what she wrote:

"For the "popping" sound, it is a procedure problem, some radio would appear the "popping" sound often, and some may appear seldom, so people ignore the "popping". For fix the problem have to change the CPU of the radio. So it can just fixed by us. If some one want to send the radio back for fixing the problem, we will fix it for free, but he should pay the freight cost. But I think the freight fee maybe too expensive, so if some one can change the clip as attached by himself, I can send one to him. But I think it is difficult for ordinary people. As you know, disassembling the radio may break the radio, and changing the clip would be much difficult. And we won't warrant the radio again since it is disassembled."

I read that as a software/code (procedure) problem in the firmware. Since the chip has to be replaced, then it must be like most other radios with a write-once chip. She sent the picture below, too. I think replacing that chip is beyond my skill level. (I'm just hoping to fix the rotary encoder when I get it and that's just three solder points! That's complicated enough for me.)

American Wouxun

I just noticed that Ed Greany had a URL in his e-mail signature. He is one of the two Eds that were always so helpful - especially in the early days - on the Yahoo group when the Wouxun HTs were just entering the market.
Check out his site: http://www.americanwouxun.com/

You are doing it wrong.

Running Humor

And on the seventh day, God did three miles - easy.



(For the non-runners, "three miles - easy" is typically considered a rest day.)
