Welcome to my Ham Radio Page!
HPD FAQ Paper on the new cell phone law.
I have an Icom 746 Pro Home Radio and a Kenwood TH-F6 Handheld Radio. I also have a Yaesu 8800 Mobile radio for my truck. Also have a Motorola FRS Outback T4900 Radio. I use a TigerTronics SignaLink USB to work Packet and PSK-31.
I like to try different modes, CW, RTTY, Packet, Satellites, PSK-31, and Voice so far.
Now that I've passed my Extra Exam I am trying to learn Morse Code (CW). I have a MFJ Pocket Morse Code Tutor Model MFJ-418. I also have a CD with code on it and the files are loaded on my daughters IPOD. I am trying to use the 418 to learn the code at 20 Words Per Minute. (I changed my call sign from WH7LH to KH6OWL on the 12 of May 2009.)
I am active on 20M, 40M, 2M, PSK-31 and satellites. (AO-27, SO-50, AO 51 and ISS)
I also have a site on USTREAM TV for video: ( USTREAM )
Sometimes you can video chat with me on Zorap.

LF: Low Frequency (30 - 300 kHz)
MF: Medium Frequency (300kHz-3000 kHz)
HF: High Frequency ((HF: 3MHz-30MHz)
VHF: Very High Frequency (30MHz-300MHz)
SF: Solar Flux
A Index: A daily index of geomagnetic activity derived as the average of
the eight 3-hourly a indices.
K Index: A 3-hourly quasi-logarithmic local index of geomagnetic activity
relative to an assumed quiet-day curve for the recording site.
Range is from 0 to 9. The K index measures the deviation of the
most disturbed horizontal component.
The propagation of radio signals in the medium frequency band (MF: 300kHz-3MHz), the high frequency band (HF: 3MHz-30MHz) and even the very high frequency band (VHF: 30MHz-300MHz) is largely influenced by the condition of our sun and, through the emissions of our sun, also the earth magnetic field that captures these.
A Index and K Index (How to read them)
The Earth's magnetic field is continuously monitored by a network of magnetometers. These readings are converted into the A and K index values. The K index is computed once every three hours (eight times a day) and the values can range from 0 to 9, with 0 being inactive, and 9 representing an extreme severe storm condition. The values are quadi-logarithmic. The A index is linear, and is computed from the eight previous K index values. It ranges from 0 (quiet) to 400 (severe storm). Generally, propagation conditions are best when the A index is 15 or lower, and the K index is 3 or lower. Besides causing auroral activity, high geomagnetic field conditions can affect the electrons in the ionosphere, reducing the maximum usable frequency (MUF).
