Hello all -
I've been an Amateur Radio Operator for over 30 years, (Novice to General to Extra). Main rig is now an Elecraft KX3 with the KPXT100 amplifier; Yaesu FT-857D as a backup. One each has a Timewave Navigator for Digital modes. Often operate 100 watts but occasional kick in a beautiful Collins 30L-1 amplifier when needed.
Main antenna is a self-designed and built 4 band compact Yagi mounted at 30' with 2 elements on 20 and 17 meters and parasitic dipoles on 15 and 12 meters which have about 4 dB gain over a solitary dipole. Backup antenna is a Cushcraft R8 vertical. Also have a 165m delta loop at about 19m in the air.
Thanks for visiting - hope to work you again! Happy operating!
Please QSL via QRZ and LoTW if possible as I'm working on several ARRL awards there as well. Many thanks,
A nearly mint condition Collins 30L-1 amplifier which I use when needed. When I first received my Novice at around 8 years old, my Dad had one of these and I lived on it with CW. I subsequently had several pieces of Collins gear including a 30S-1 and S-line but sold them all off. I'll be hanging onto this amp however - what a workhorse and nothing beats the smell of the four final amplier tubes when they've been working hard!
Detail of the 20m driver and the parasitic drivers for 17, 15, and 12M. Each driver is insulated from the boom. Reflectors are only utilized for the 17 and 20m bands. Still, the dipoles at 15 and 12 m have about 4 dB gain over a freespace dipole due to coupling the 20 and 17m reflectors.
A simple way of taking advantage of the geometry of the house - the antennta mast is mounted on a hinged base. The mast is lowered using an electric winch mounted on the back of the 1955 IH 300 Utility tractor pictured on the side. There is a loop mounted at the eave of the porch next to the thrust bearing which supports the antenna at about the 15' point. This setup gets the antenna about 30' in the air.
Alpha-Spid Rotor mounted on a 10' deck with support underneath. Aluminum heavy duty hinged base, 22' Chromalloy hardned mast. Highly recommend this rotor.
