--AMATEUR RADIO STATION--
984 VALLEY ROAD
MASON, NH 03048
Paul Gili, Chief Op.
Chief Operator is also the Trustee of
W 2 O P B
[The Bay Haven Radio Klub (BARK) of Mason, NH]
Interests include, but are not limited to:
Morse keys and keyers
HF/VHF antenna building and design software
HF Utility signals monitoring
QRP / Portable operation with antenna challenges
The secrets of: AA1LL/M/QRP/CW
The station always answers QSL requests. Frequencies monitored are 3530, 7030, 10110 and 50090kHz + 10kHz.
A contact could get you one of these!
The earth's ionosphere is affected by its magnetic field. When there is high magnetic field activity, the ionosphere becomes lossy and no matter how high the solar flux (which determines MUF), HF radio propagation conditions will be worse than when the geomagnetic activity is low. The planetary A index, Ap, is a measure of this activity. NOAA publishes predicted values of Ap at the 27 day outlook. There is more information at The DX Listener's Club and the solar real time display.
Try this Helical Antenna Nomograph, which uses an approximation derived from measured results (Yusof and Hassan, "Regression Analysis of Resonant Frequency... of Normal Mode Helical Antenna," TENCON 2000 Proceedings, Vol.2, pp228-231):
The equation is: # of Turns= N=( 905 / (Freq(MHz)*DIA(in)) )^1.25
[It's fun to make your own nomograph!]

Here are some D/A converters (digital to arcane) for your viewing pleasure. Some of you have had the (dis)pleasure of hearing one or several of them at one time or another!! Clockwise from 1:00:
-Vibroplex Blue Racer, painted black (oh well, it was the '60's)...
-Key WT 8amp imported from G-land, came in box new...
-Slightly rusted chrome Speed-X, fun to bat around...
-Home brewed sideswiper used on SS net...
-K1EL K10+ TIC elec. keyer in smallest Radio Shack box, with HB paddle, 3 buttons for 3 messages...
-Hole-in-the-Wall TACO key, my favorite...
-Home brewed sideswiper, also used for keyer paddle...
-Jackson Harbor Press PK-Basic in box with integrated HB paddle....
-Whiterook MK-11, amazingly easy to send good code with this inexpensive key
