The very first full charge is very important to optimise the battery life time.
This is why reading the manual before playing with his toy is very important.

Should have clarified this - it was on external power when trying to power up originally. All ok, charging now on the dock the unit allows use with external power whilst charging.

What is the basis for this claim?

Are you talking about the overall useful life span of a lithium ion cell as opposed to it's operational functionality in a single discharge cycle?

Japanese is a wise, reasonable person who takes the time to understand, analyze and think before positioning and building. He's not an impulsive person like a European or an American

If instead of taking the time to share with them, if you unpack everything in the public square, then in the eyes of the Japanese you lose all honor and credibility and you are no longer worthy of their interest because you disrespect yourself.

To act like a conquering knight who fires the citadel does not frighten them.
This is exactly how I said this, but with other words, in a FB group and got bashed for it. The more you hammer and insist on that culture, the less you will receive. The the contrary.

Thanks for your support. On this forum, I denounced, proof to support, manipulations and other mishandled malpractices.

In return I received a volley of green wood!

It is obvious that the more the critics are asserb, the more the respects and the credibility are granted.
Although unfortunately, it is the one who makes the first dirty grime in the white snow that passes for the one who rightly.

yes on this point you are correct.
BTW a long time ago the Dutch where the only people the Japanese like to trade with

Any updates on AOR ARDV10 problems?

All DV10s have the same frequency error / drift problem, if its tuned to a stable unmodulated carrier in SSB mode and the audio output monitored with a sound card you can see the pathetic attempt to keep it on frequency as the frequency jumps and wobbles by as much +/- 50Hz as it drifts, you can hear the warble.

We decompiled the firmware to see what was going on, these formula are used:-

PLL_REF = (CPU Temp - C1) x ((C4 - C3) / (C2 - C1)) + C3
OFFSET = (CPU Temp - C1) x ((C4 - C3) / (C2 - C1)) + C3

CPU Temp comes from the RX63 internal sensor, calculated from hex into 0.1 deg C steps. C1 is the start of the temperature block which are 5 or 10 degree blocks, ie 300 is 30 degrees C. C2 is the end of the temperature block ie 350 for 35 degrees C. C3 and C4 are the PLL_REF and Offset constants at the start and end of the temperature block.

All the formula does is takes the values for PLL_REF and OFFSET AOR have GUESSED will put the DV10 on frequency at the beginning and end of each block, the difference is calculated (C4 - C3) then divided by the number of 0.1 degree steps in the block (C2 - C1), 50 for a 5 degree block or 100 for a 10 degree block. The adjustment value is then added to the PLL_REF and OFFSET temp block start value.

The result is that every few milliseconds PLL_REF and OFFSET are jumped around by as much as +/- 50Hz.

First problem, CPU temp is extracted from the internal sensor in the RX63, this temperature is not the temperature of the XCO so depending whether the backlight is on or off and power connected or disconnected the XCO heats up differently from the CPU, the 2 temperatures do not track the same way.

Second problem, the 2 sets of constants in C3 and C4 are way off on my DV10 which means they probably all drift with different gradients.

Third problem, the adjustment values are added on top of the DV10 base PLL_REF and base OFFSET, comparing 3 radios all have had different base values, 1 by a value 16000 lower than another.

Fourth problem, even if this was an acceptable method (which its not) the adjustment should be much less frequent to avoid the continuous warbling.

Fifth problem, the cpu core temp wobbles up and down but the XCO always drifts the same way.

Their botched fix must have taken about 30 minutes, clearly no time or engineering thought went into it, instead they decided to continue to add more useless features.

None of AORs products can now be trusted, they refuse to accept there is any problem despite it being proven, the only way AOR could ever be trusted is to admit the problem, recall and fix their faulty rubbish. At this point they continue their arrogrant ignorant stance and continue to try and sell the DV10 with its many defects.
---------------------------

Many have been returned to suppliers, many have been returned all over the world, Japan, Australia, Singapore, USA, UK, Germany, Netherlands, France

Several very smart people have looked into all the issues and AOR is refusing to accept the issues raised by people all over the world.

My advice without AOR doing a recall of all units and replacing them - or your dealer giving an undertaking to do so - is DO NOT BUY THIS UNIT - independent tests have confirmed (from Australia, UK, Netherlands, Germany, USA) it does not meet the specification as marketed and is not reliable in it's current state.

Its also worth mentioning that the 50Hz, is the result of a customized firmware. We have optimized the firmware to stay closer to its intended frequency. Before that its was more or less 200hz off.

Every device has a different PLL base offset, therefore we cannot make a generic patch for all devices.

If you are interested in these developments, join our facebook group. I can freely speak there without being moderated all the time

Discussions on the DV10 are better off in the Facebook group, for some reason all the posts on here are ridiculously moderated, maybe AOR or Yaesu are paying to have posts moderated and supressed.
