I placed 2nd in the category according to my certificate: 2nd High Single-Operator Phone QRP with 4,108 points. I used an HT and a roof mount antenna on my H3. I drove about 500 miles on Sat and Sunday solo, no fancy bi/tri/quad grid square trickery was used. I look forward to participating again next year./

About me

I live in grid FM18gt (Centreville, Virginia).

I have wanted to be a ham for a very long time so I finally took the exam for technician, passed the exam with a 34/35 in March 2014. I upgraded to General class on 12/2/14 by passing element 3 (aced it!).

I operate my HF shack out of my basement, its in development.

I enjoy digital modes: JT65 (probably 90% of my time), PSK31 (5%), as well as SSB phone occasionally.

My first antenna (technician license, March-Dec, 2014) I used for 10M and 6M. I worked ALLOT of stations with this < $30 setup, as a technician you CAN WORK HF on these bands. I take this antenna mobile, with a tuner, for multiple bands.



Vertical: This is my modest 10m MFJ hamstick antenna, its mounted to a scrap piece of aluminum angle bar with one 18ga stranded bare copper wire about 8 feet long at about a 45 degree angle.

Measured SWR: 28.074 [2.5-3:1], 28.118 [2.5:1], 28.394 [2.0:1], 28.496 [2.0:1] (MFJ-945E turner off)

Dipole: NEW: Chameleon EMCOMM II Dipole Antenna (love it so far) - 12/29/14

It is about 30 feet in the air in an inverted V configuration. I can finally talk to people east of the Mississippi and I QSL'd with Antarctica (JT65a, 30m, 4 watts).

Yes, I own a TNC and I am not afraid to use it!











I run a KPC-9612+ and a Yaesu FT-2900R, it's a PBBS and a WinLink VHF node.


I have a few test nodes, they are not always operational and are short-range (0 - .4 miles):

  • kk4zuu-mobile: linksys wrt node, external 5dBi antenna
  • kk4zuu-base: ubiquity nanostation loco m2
  • kk4zuu-inet: ubiquity airRouterHP


I currently submit digital QSLs to LoTW, eQSL, and QRZ. I do this manually so I appreciate a QSL in kind.

I have envelopes at my local QSL Bureau, I hope to send out a QSL card to everyone I have worked. If you sent me a card I still have it, I want to order some cards before I send out mine so hang in there and/or QSL digitally (LoTW, QRZ, eQSL).
