Hello, my name is David. Welcome to my QRZ page!

Mobile/Expeditions/Special Events:


2017 ARRL Field Day, operating remotely while camping

2017 13 Colonies as K2B (VA) 7/1/2017 1300 to 7/7/2017 0400 UTC [digital - jt65, psk31, RTTY]

I will be operating jt65 as K2B for this event for the great state of Virginia again this year.

QSL and event information is on the official website (http://www.13colonies.net/)

My operating schedule (google docs, new window will open)

The jt65 exchange for the special event is close to the standard, only the final sequence is being modified and is shown in the example above.

The Free Msg text area in WSJT-X (for example) will allow you to send the final required part of the exchange.

I have one antenna and one transmitter so it's one at a time.


13 Colonies Special Event (7/1/16 1300 UTC - 7/7/16 0400 UTC)

I operated jt65 as K2B for this event for the great state of Virginia. QSL and event information is on the official website (http://www.13colonies.net/)

07-04-16 - I worked K2D via jt65 as K2B on 40M. That was a surprise, seems I may have started something for next year. 96 Q's in the log so far, given the band conditions I had people thank me for 'thinking out of the box' to get signal to their area.

Va QSO Party, March 21-22, 2015 - KK4ZUU/M was active in the Virginia QSO Party for 2015 (2m, 70cm). 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).
