Ham Member Lookups: 2617


I was first licensed in 2005 as a No-Code Tech, and finally got around to upgrading to General Class in November 2012. I got interested in ham radio as another element of emergency preparedness, but have come to be interested in it for the technical aspects.

My radios are:
  • Icom IC-7200 for HF
  • Yaesu FT-817ND for QRP HF, 2M, and 70cm
  • Yaesu FT-7800R for 2M/70cm at home
  • Yaesu VX-5RS for 2M/70cm on the go
  • Baofeng UV5RA 2M/70cm as a backup HT
  • Ultimax-100 end-fed wire for HF, fed through an LDG IT-100 tuner
  • Comet GP-3 for VHF/UHF
  • Hawaii EARC end-fed for HF in the field
Here's crummy iPhone pic of my IC-7200 and LDG IT-100 tuner:

My antennas are mounted on my roof. Here's the Comet GP-3 for 2M/70cm, strapped to my chimney. The Comet has been up there since 2005 or 2006 and still works great. My Ultimax-100 antenna for HF is attached to the base of the mast supporting the Comet.

(I need to paint the chimney. It's faux brick.)
This is the short mast I made to support the other end of the Ultimax-100. The base is made from 2x4s covered in black Plasti Dip. The mast itself is a 30 inch piece of 1/2" black iron pipe, also covered in Plasti Dip. Why Plasti Dip? I already had it so I decided to give it a try. We'll see if it holds up to the weather. It turned out that the winter of 2013 - 2014 was too much for the Plasti Dip. It's all gone.

I've also gotten into operating from battery power while truck camping.

My setup above consists of my IC 7200, LDG IT100 tuner, 31' (~10M) Jackite telescoping kite pole slipped over a piece of rebar pounded into the ground, Hawaii EARC end fed antenna, and a Harbor Freight Cen-Tech 12V portable power supply. The laptop is a 2008-vintage MSI Wind U100 netbook running Windows 7 Ultimate and FLDIGI. I want to replace the drive in the netbook with an SSD to improve the performance a little, but mainly to boost battery life.
I am largely interested in digital modes on HF, primarily PSK31 and Olivia, so far. I've tried Ham Radio Deluxe + DM780 and also FLDigi, preferring FLDigi in Windows or Linux. To me, the digital modes are natural extensions of my day job which involves administration of Linux, Windows, and VMware vSphere servers for a Fortune 500 company.
In December 2014 I activated "Deer Camp On The Air" with my FT-817ND, using PSKER on my iPhone 5, acoustically coupled to the radio. I powered the radio using a 5 mAh LiPo battery from hobbyking.com.
My portable setup now consists of the FT-817ND, an Apple iPad Mini2 with Logitech Bluetooth keyboard, PSKer, and an Easy Digi interface from KF5INZ.
FT-817ND, etc.
To go with the QRP rig I built an "FXtenna" based on the design by KD5FX. Pictures of my implementation are here:
