Hello I am W4PRE my first call, in 1977, was WD4KTG thank you for looking me up in QRZ. I live in Ooltewah, TN just outside of Chattanooga, TN. My interests include homebrew antenna building, homebrew HF amps, working local VHF and UHF stations. I am a manufacturing engineer in the metalworking industry and have been using CAD, CNC Programs, and PLC since the late 70's. I enjoy working Field Day, the November Sweepstakes contests, and rag chew. I wish to always remember one of Elmer's, "Pappy" K5PRE and thank him for the kind help and patanice in getting me on the air during my novice period. Active in the the local Chattanooga Amateur Radio Club, TN, and ALA phone nets.
Currently I have up a 40' fold over tower witha home brew 5 band 2 element boomless quad HFbeam for 20m thru 10M. I have a second 55' tower for VHF and UHF operation with a Cubex KingBee III quad with 4 elements on 6M, 8 elements on 2 meters, and 8 elements on 440 Mhz quad all on one 8' boom. I run a fan dipole with wire elements for 160, 80, 60, 40 and 30 meters wire antennas. Just in late March 2014 I put up a 80M full wave loop feed with 450 ohm balanced ladder line; experimenting on 80, 60, 40, 20. meters to see how it compares to the fan dipole and the 2 element boomless quad. Next will be a 160M full wave loop in 4 to 6 weeks after I have completed the actual patterns,.
The current HF station is a Yaesu FT-950 with Heil PR-40 microphone and Kenwood TS-733 on VHF/UHF. I run a ALPHA 76A that was convderted to (2) 3CX800's or only the rig with 100 watts. I use a Palstar AT2K as my HF antenna tuner if needed. I run the RigBlaster Plus for digital CW modes PSK31/125 and JT65; just getting started into the the digital communications. I will post more photo's of the antennas as they are completed and up on the towers.� Station control is Ham Radio Deluxe with logging; several antenna modeling programs and Excel spreadsheets are used for antenna design and analysis with antenna analyzers from Fox Tango and MFJ 259B.
e-mail address is firstname.lastname@example.org for general communications
73's and have many QSO's
Above is the my electronics work bench beside my operation station where I build amps, kits, and do my soldering. That is the converted Dentron MBL2500 amp (uses a single 3CX800A7) on the bench shown in this photo - I am replacing one of the relays.
Above is my home brewed 2 element 5 band boomless quad beam for 20/17/15/12/10 meters. The center of the quad is at 40' and the trees around it are 60 feet. There is a remote antenna switch for each driven element just below the boom and all unused elements are grounded when not in use. Each spider arm is fiberglass tubing 15' long that are expoxed in place.
This is me, W4PRE (aka Whiskey 4 Peter Rabbit Ears)� in front of my fireplace.
