Lettine 240 AM/CW 40 Watt transmitter
I was introduced to ham radio at age 8 by my uncle and a neighbor W2FU. I learned to copy morse code on a Collins 75S-3 receiver. I lost interest during my teens but returned to radio in my early 20's. I met W1JBV who got me started back in ham radio. He was the Chief Engineer at our local broadcast radio station out of Bridgeport CT. (WICC 600) . I would go to the transmitter sight on the weekends with him and accompany him to field strength measurement sights to check the phasing of their 2 element vertical tower array located on Long Island Sound.
He taught me electronic and antenna theory and helped me build my first receiver, transmitter and rf linear amplifier.
I operate mostly 40 meters and enjoy experimenting with antennas. I found that the full wave loop to be the most effective antenna at my QTH. I live on a 600' ridge with clear views in most directions. I have used single loops both vertical and horizontal, phased loops, 2 and 3 element fixed directional and now having fun with a 4 element array directed towards ZL and VK. I QSO with Mike ZL1BVB on 7.009.6mhz. and Page VK3RP (over 500 QSO's) when morning conditions allow. The antenna also has a forward lobe towards Europe and North Africa and works great when I QSO with my good friends CT1ZQ, EI6AK and F6ACD.
Thanks for stopping by...73
7 Mhz Colinear Loops with directors to VK/ZL
One half of the Colinear Array Diagram of 5/8 wave spacing. Works well with 1/4 wave spacing also
I will be installing two new beverage antennas this fall. One will be 360' of solid hard drawn enameled copper at 18 ga. orientated NE to SW. The other will be 240' N to S.
3 Element Relay Switched 40M Delta Beam�
This is another loop configuration I have used .... It takes some time and effort to get spacing and feed line phasing right but once you find the sweet spot it "REALLY" works well
Home brew 160 Meter Mobile whip on my Plymouth Champ and my station from 1979, still have same Collins S line since 1978,
I am also a motorcycle enthusiast. I have been riding since I was 15 years old. Designing and building custom motorcycles keeps me busy during the warm months. Restoration, metal fab and paint are all done in house.
