Wouxun KG-UV920R Mobile

UPDATE; Click Here
I'm all for cheaper radios and equipment in this wonderful hobby of Amateur Radio. Being on a fixed income I can only afford used equipment at this point unless I save for several months. Wouxun has plans to release a New Dual Band Mobile unit. It sure looks awesome. Read the Specs. From what I have read it's in the $150-$200 price range. If that is the real price range, it's going to upset the Amateur Radio world as far as prices are concerned.
------------------------------------------------------
The KG-UV920R is Wouxon's first dual band rig, operating both 2 meters and 70 cm (440 MHz). Power output is selectable in 3 steps (2m: 5/25/50W, 70cm: 5/20/40W) and modulation can be switched between narrow-FM and regular-FM. The receiver covers the entire HF band, 65-220 MHz and 400-520 MHz and supports AM. A detachable front panel and DTMF-mic come standard.
Frequency range RX 0.15-30 / 65-220 / 400-520 MHz
TX; 2 m / 70 cm
Modulations RX;AM / FM / N-FM
TX; FM / N-FM
Tuning steps; 5 / 6.25 / 10 / 12.5 / 15 / 20 / 25 / 30 / 50 / 100 kHz
Features;
DTMF-mic
Detachable front panel
Called ID
Twin RX
Cross-band repeater

HOW TO READ PROPAGATION NUMBERS

The A index [ LOW is GOOD ]

  • 1 to 6 is BEST
  • 7 to 9 is OK
  • 11 or more is BAD

Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.

A lower A-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Ap-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.

SFI index [ HIGH is GOOD ]

  • 70 NOT GOOD
  • 80 GOOD
  • 90 BETTER
  • 100+ BEST

The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.

Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; Solar Flux rarely affects the 30, 40, 60, 80, & 160 Meter Bands.

K index [ LOW is GOOD ]

  • 0 or 1 is BEST
  • 2 is OK
  • 3 or more is BAD
  • 5 is VERY VERY BAD

The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.

A lower K-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Kp-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
