WH6HI On Kauai in the Hawaiian Islands
Page updated 2/12/2017
Radios: Flex-6500/GPSDO, Flex-1500, FT-8900, Baofeng BF-F8HP (VHF-UHF)
Microphone: Audio Technica AT 2035
Audio Processing: dbx 286s
Power Supply: B&K Precision 1900 (Repalces Samlex SEC 1235M)
Amp: Elecraft KPA500
Antenna: ZeroFive GP1040 Ground Plane Vertical
Antenna, receive only: DX engineering RF-PRO-1B Active Magnetic Loop
Antenna Tuner: Elecraft KAT500Associated Equipment: Computer NUC i5, Elecraft W2 wattmeter, GPS time server Time Machines TM 1000A
Software intergration: All the station equipment is fully intergrated via software run NUC i5 computer. System control is tied together using DDUtil v3.2.5 and allows the Flex 6500 to control the KPA500 RF Power Amplifier, KAT500 Antenna Tuner, the W2 watt meter. Other software that is intergrated via the NUC is WSJT-X, JTAlert and Log4OM.
Digital modes: Software used for the digital modes are WSJT-X, JTAlert and Log4OM. These applications are intergrated and work together via TCP/UDP communications within the NUC. As of now Fldigi, is not intergrated with the Log4OM and is a work in progress, but is inter grated with the Flex6500 via RigCat.
SSB mode: SSB only uses DDUtil to fascilitate the control of the amp and tuner. Loging is doen manually.
Time and Frequency: Time and Frequancy referance and adjustment is done via two GPS recievers. The first is a local NTP on the LAN, via the TM 1000A. The other GPS RX is in the Flex6500 and provides a highly accurat frequancy referance for the internal clock of the radio and 10MHz port for external use.
GPS set up: The GPS RXs use a single active antenna that is on the roof. The signal is split two ways to provide signal to eachGPS reciever. Power for the Active antenna is provided by the Flex6500 and power from the TM 1000A is blocked by an internal jumper.
RX Frequency Referance distribution: The Flex6500 provides 10MHz time refernace signal to the Flex1500, locking the two RXs together. In the future the Referance will also go to Transverters for other communications projects.

Great DX Location at all wave lengths!

My pride and Joy, my 2011 Chevrolet Volt and of course it has a radio (VHF/UHF) in it.

My Station Evolution Through the Years
Above is the last Tewksbury MA Station setup before the move to Hawaii. With new mike, computer and Flex1500
2014 Year of the Flex
This is the Flex6500 Station with the flex3000. Also owned a Elecraft KX3 during this time.
A flash from the past. Below was my dream station in 1984.
And this is the antenna that was used with it. There was also a 450 ohm fed inverted V for 80 and 40 meters.
Putting the tower together with my freinds.
The KT-34A Being mounted to the tower.
Raising the tower. There was a duel eyelet at the peak of the roof that was used to winch up the tower. My back yard was only 12 by 20 feet. This required the use of a self supporting tower.
Finished tower project.
