Vertical Antennas, Radial Length and Number of Radials by Rudy Severns, N6LF

Here is a very good article written by Rudy Severns, N6LF.
http://www.antennasbyn6lf.com/files/radiation_resistance_variation_with_radial_system_design.pdf

It answers many questions hams have about vertical antennas and how the number of and length of radials influence the radation resistance of vertical antennas made for the 40 M band.

Ground resistance soil conditions are also taken into account and  discussed.

NEC models are used.

Alaskan Arrow Satellite Antenna

I didn't know Arrow made a 2M/70cm antenna with more gain. It's made for Hams living in higher latitudes, thus the Alaskan Arrow name.

It's larger and heavier so a Az/El system is needed. I wish there was a low cost Az/El rotor system available for these smaller, portable and light weight antennas.

k8ZT's KX-x LCD Display Expander

" The KX-QRP 2nd L👀K is an accessory for use with the Elecraft KX2 or KX3 Radios. These radios have the ability to decode RTTY, PSK and CW signals (without a computer) and display them on their front panel. The display is 7 characters and scrolls as new text is decoded.

I wanted a way to display more characters so I designed the 2nd Look. It is offered as a kit to others that want a bigger display at a low price."
