Hello all -
I've been an Amateur Radio Operator for over 30 years, (Novice to General to Extra). Main rig is now an Elecraft K3S K-line: K3S, KAT500 and KPA500 with the spectrum scope. Nicest rig I've ever owned or operated. Backup is an Elecraft KX3 with the KPXT100 amplifier. Have a beautiful Collins 30L-1 amplifier that was my workhorse for nostalic reasons mostly (and I love the smell of hot tubes on a cold Sunday morning) but have taken it offline to make room for the Elecraft.
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 that is an excellent performer. With the delta or R8 connected to the secondary receiver on the K3S in diversity mode (the yagi w/ horizontal polarization goes to the left audio channel and the delta or R8 goes to the right), very weak signals or signals through fades make it through - highly recommend the second receiver on the K3S!
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 recently took offline. 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.
