12/17/2014 License upgrade to Extra Class.
Hello Ham friends. I live on the West coast of Florida 50 miles north of Tampa. I started in radio in the mid 1970s. I am a retired firefighter and did constant radio communications over my 27 years with the FD. Got back into radio in 2011 and really enjoy Ham. I operate a Yaesu FTDX 3000 with a Heil PR781mic. A hard wired MFJ 259B Analyzer to keep an eye on things. Amplifier is a Acom 2000A. Antennas are a Mosley Pro 67 C3 at 75' on a Rohn 55G tower and a homemade 80 meter wire at 55' on a seperate tower. Mobile in my 1992 F250 4X4 is a Yaesu FT 890. So 73 to all and look foward to making lots of contacts and friends.
God Bless KA4SFD

The KA4SFD Pro 67-C-3 project finished at last. Three months from start to finish.
Thank you to everybody that contributed to this project it could not have been done without you. Projects like this give you a greater appreciation for all the knowledge that other HAMS have to offer. And then in turn we hand down to others.
Special thanks to KK4ZDS, Wayne, my friend and right hand man. Perhaps I was his right hand man, hihi. The countless hours and late nights we spent working on this project together was a great experiance, very educational, lots of hard work, and we had lots of fun along the way.
