Dear Jim, and all the others who replied, Thank you for your responses. I am building the interim loading coil as a solenoid, because of simplicity and materials available, which include: PVC Formers
Dear J, I was thinking of reducing the solenoid loss by paralleling two or more #17 wires and close-winding them. If I parallel wind three #17 wires will it be worth the effort in reducing coil loss

Mike, Alex and LF, I agree that spending my time on the antenna and ground would produce a more dramatic improvement, but it is winter in Yukon, and -30 outside.... I am trying to get my initial sign
...About 1.2mm, according to my ARRL handbook. Acording to estimation done number of turns to get about 700 Ohms is 55 if former diameter is 320 mm. Optimal length of solinoid is about 160 mm. If wir
Alex, Thank you for running the calculation for me. I will wind the coil with 55 turns to a length of 160 mm and use the roller inductor for fine tuning. 73, J. -- Original Message -- From: "Alexande
