As a career change, I decided to become a stock broker. I studied and passed Series 7 and Series 66 licenses given by FINRA in 2002.
Present position is Vice President of Investments at Merrill Lynch with a title of Senior Financial Advisor.
I was originally licensed as a Novice class operator (WN5AKK) in the summer of 1962 while in college. My brother, K5JAJ (now W5RDW), had become a General via a radio operators club at our local high school. The exam was administered by our family friend, K5DNF. The Novice license expired in 1963 and was not upgraded because of other interests (graduate school, etc). Forty five years later, I became interested in ham radio again after my brother had notified me of the changes in Amateur Radio. I was relicensed in May of 2007 as KE5OQV after completing an exam for Technician class.
The units shown in the photos below are my personal Collins S-Line collection, split between my two QTHs, Houston, TX and Hilton Head, SC. Both Round Emblem and Winged Emblem type units are represented. Also represented in the collection are different types of microphones as well as various accessories such as dummy loads, novice adaptors and noise blankers (both WE and RE). The collection has been maintained in excellent cosmetic, electrical and mechanical condition thanks to the efforts of Dutch Maurer, WB7DYW, now a silent key.

The Collins station in Houston, TX consists of a KWM-2A transceiver, 75S-3C receiver, 30S-1 linear amplifier, 312B-4 control station, SB-610C-3 scope, 516F-2 power supply (on the floor) and a SM-3 microphone. The scope and receiver are from the estate of WB7DYW. The RF signal is continuously monitored by a WaveNode RF sensor. The RF signal goes thru a PalStar AT2KD tuner before going outside to the antenna, a Mosley MP-33.

Next to the desk is the 30S-1 Linear. Power output and SWR are continously monitored by a WaveNode RF sensor. Signal quality is monitored by the Heathkit SB-614 hamscope.

Low loss 52 ohm coax from DX Engineering is used to transmit the RF signal from inside the shack to the Delta Loop antenna. The wires from the Delta Loop terminate at a 4:1 Balun. A set of bungee cords attached to a dipole fixture provides flex to the antenna system.
The Delta Loop antanna (or more correctly, a pentagonal loop) was designed using the EZNEC modeling software. The final model called for 141 feet of #14 stranded wire configured as a horizontal loop.
(The photo is outlined in black ink so as to better visualize the arrangement of the wire).
The Delta Loop antenna is suspended parallel to the ground using the existing trees on the lot. It's approximately 30 yards from the water and stands 35 feet above sea level. It resonates at 10, 15, 20 and 40 meters with an SWR of less than 1.5:1 on all bands.
