EQplus: 8-Band EQ/Noise Gate

Use EQplus to expand your W2IHY 8-Band EQ/Noise Gate. Connect one simple cable from your 8-Bander to EQplus and you’re connected to world-class audio capabilities.

EQplus can be used as a stand-alone unit. If the onboard Dual-Band EQ meets your needs, put EQplus between your microphone and radio. If you find you’d like to have additional adjustability and control, you can always add a W2IHY 8-Band EQ later on.
Rack users: EQplus is a one-of-a-kind accessory that gives you unmatched capabilities in radio interfacing, impedance matching, level control and RF/audio isolation. Nothing else compares at any price.

Features:

Adjustable Compressor gives your signal a serious boost in loudness. Increase talk power while your signal stays squeaky-clean
Adjustable Downward Expander provides ultra-fast and transparent background noise reduction
Limiter manages onboard levels and works in harmony with compressor for big, full, commanding audio
Convenient front panel controls
Interface up to 3 radios
Use the Dual-Band EQ for a finishing touch on your lows and highs
Effects Processor adds smooth bright presence to your signal.

Field Station (1)

Today I spent some time working on my field station.
I'm hoping to get to to Pere Marquette Beach in the next few weeks and see what kind of DX I can work.
I also plan on doing several night time field setups this summer.

As of right now I'm not sure which antenna I will use, I leaning towards my MFJ-1798 which will operate 10 bands -- 75/80, 40, 30, 20, 17, 15, 12, 10, 6 and 2 Meters.
The MFJ-1798 is a great antenna that requires no ground or radials!
Making it a great field antenna.
I hope to work your station.

As for what radio I will be using, I will be using my Yaesu FT- 897D.

I will be posting more info as I plan with dates.

I hope to add your station to the log book.

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.
