    I recently started working with Calvert K9 Search, a local SAR team that specializes in using dogs to search for people.  In an effort to improve communications between the command post (base) and teams …

  2. N6NB VHF/UHF Quad Antenna

    N6NB VHF/UHF Quad Antenna drawingI'm interested in VHF and higher bands.  Unfortunately my current home doesn't permit me to really dive into these bands like I'd prefer (with LOTS of big antennas!).  So, to get my fix, I'm hoping to build a rover station that I can use go catch some new grids and …

  3. Now on medium wave!

    160m on Kenwood TS-2000XYears ago I purchased a 40-80-160m dipole antenna in hopes of getting a good signal out on the lower bands. Unfortunately the antenna ended up being too large for my yard and I didn't use it.  Fast forward to now and I've got plenty of room for antennas.  When I …

  4. Antenna maintenance

    The weather was nice enough for me to get some of my antenna maintenance done that I couldn't do during the cold winter months.  First on the list was to completely remove the 23cm (1.2GHz) antenna from the top of the tower.  While I've had good luck working stations …

  5. All antennas up in the air.

    image0
    All antennas are up. I now have 11 elements on 2m, 22 elements on 70cm, and 25 elements on 23 cm. I was able to trim a couple of branches out of the nearby tree and now my antennas swing nearly free through space.

    I've also noted that the only …

  7. VHF/UHF Update

    Well, things took a slight turn for the worst last night. After receiving the UT-10 and the coax, N-connectors, and rotator control wire I realized that the pole I have stuck up in the air isn't wide enough to support the rotator. Apparently the pole is 1" in diameter and …

  8. New toys...

    I haven't posted anything lately but that doesn't mean that nothing has been happening.

    First, a couple of weeks ago I found a Kenwood UT-10 1.2GHz module for my TS-790A. I've been looking for one of these for going on two years. Finally my eBay alert came through and …

  9. 20m Vertical Erected

    Last night I put the final touches on the 20m vertical antenna I built the previous night. Looking over everything and checking it twice I thought I had everything taken care of. I looped a branch in a nearby tree and pulled the antenna skyward so that the base was …

  10. New HF Antenna

    I'm going to build a new antenna I found in the 2003 edition of the ARRL Handbook. This antenna was originally published by the ARRL in their September 1984 edition of QST in which Chuck Hutchinson, K8CH, explains his "Tree-Mounted HF Groundplane Antenna".

    I will be building the 20m version …
