"I've lost 2 Wouxun radios to the "Suicide Chip" bug. Additionally, the popularity of this brand has waned. When my third radio fails, I'll no longer have any interest in Wouxun radios.
As a result, I'll be leaving this group after a new owner is found. If interested, please let me know.
Thanks... John KD8DVR"
Congrats to the USWNT!
A very surprising match... I was expecting a very close game, not:
"How did you get a hat trick in the World Cup final?" "I scored from midfield in the 17th minute."

Baofeng Tech: Baofeng UV-82HP
Much better news for the Baofeng UV-82HP coming from John's review on Miklor.com:
"- The original UV82 took a traditional UV5R, and added design features such as an upgraded case design and Dual PTT switch. (comparison)
- Next came the UV82C which included the options to synchronize the Dual PTT function to emulate a Single PTT, and the ability to lock out the VFO to prevent accidental field programming.
- Next came the 8W F8HP. This was the radio that started the HP / TP movement.
- An expanded feature added is R-Tone, a repeater tone for those requiring a 1000, 1450, 1750 or 2000Hz audible tone for access. This is not to be confused with CTCSS or DCS. Prior models provided Tone Burst for 1750Hz only.
The UV82HP now includes all of the above features in one package. The PTT synchronizing, VFO lockout, High Power, R-Tone, and newest generation chipset.
It has kept the traditional UV82 case design to ensure compatibility between all existing options, including Dual PTT Spkr/Micr, battery cases, holsters, battery eliminators, etc."
QYT KT8900: Miklor Review
Some bad news (at least for now) for those of us that were interested in the QYT KT8900 / Juentai JT-6188...
John's review at Miklor lists the cons including some serious ones:
John's review at Miklor lists the cons including some serious ones:
"The Audio issue is serious.Specifically:
The inability to use the software on a Windows PC is disappointing.
No external Speaker jack. The port in rear is for programming cable only.
No 2.5 kHz steps (relatively minor compared to above)"
"- No Audio on an Active ChannelRead the whole review here.
This one is a bit nasty.
When changing or returning to an Active Channel, no audio is present. You must press [EXIT], or press the PTT to open the squelch. If you are in the scan mode, it is possible the radio will stop on an active channel, but no audio will be heard.
This is also found in Section 3 at the Miklor FAQ.
- Humming Sound
Not major, but worth pointing out. When a signal is present and the audio is fully turned down, there is a humming / buzzing sound that comes through the speaker. When the volume is turned up, the sound is no longer noticeable. This is not a Power Source issue."
