Hi, and thanks for stopping by!

  I am now in Ohio operating from our new home near Dayton. I am still back and forth on changing my callsign, but I really like NC5T and am really leaning towards hanging on to it as we don't have to change calls when we move.

  I finally have my Ten Tec rigs back up and running (Omni VI+, Pegasus, and my Omni D) but still have only the 40M dipole up.  It looks like the Omni VI+ took a beating in transit as it is off frequency on transmit so I will have to fix that, but the rest, so far, seem to be working well.

 We have several 60ft trees that will make great antenna supports once I figure out what I want to do for antennas here.  These will also help keep them kind of stealthy as, although there are no restrictions on antennas, we are in a neighborhood so I am going to try to keep a low profile...at least for now.

I use EQSL, LOTW, QRZ Log and QSL 100% direct (no SASE required).

73,

Bob

RV/ Portable Operation:

 What I have so far, and is working very well, is a bugcatcher style antenna using a 30' painters pole and a large coil.  The pole is aluminum and to make sure the sections have decent continuity I used some bare copper clamped between the sections.

  The coil is made from lexan wrapped with #14 solid copper wire and is sidemounted to the pole at the bottom.  It is really a bottom loaded vertical with about three feet of wire from the coil to the coax connector.  

It tunes flat on 40M and 80M and with the coil bypassed, works all of 20M.

Other than this, I have a couple of Hamstick for 40M & 20M that get me on the air without the hassle of setting up the big antenna.

 

Here is a rundown on my projects from my old shack in Texas.

  

 Shack gear consists of:

  • Ten Tec Omni VI Plus
  • Ten Tec Pegasus
  • Yeasu 857D
  • Ten Tec Omni D w/VFO
  • AL-80B
  • MXL 990 w/ Behringer x802
  • MFJ 969 Tuner
  • HB Link Coupled Tuner
  • HB Rig to Computer Soundcard Interface
  • HB Radio/Antenna selector switch
  • Semi-HB DVB-T Panadapter set up
  • 100% Homebrew Antennas

My antenna projects include:

Multiband ground mounted vertical

  It is sort of a fan vertical as I built it with two radiating elements and 32X33ft buried radials. The poles are separated by about 8 inches centered in the radial field and I have it fed with a 205 foot run of RG-6 all the way to the shack.

  This has turned out to be an amazing antenna and is working much better than I thought it would. and It covers not only the 3 design bands without the need for a tuner, it also covers a good portion of 75M and 10M, and all of 30M without the need for a tuner .

 

Fan inverted V dipole for 40/20

  I have it on a homebrew 55ft tilt over mast. It's not really a fan dipole in the truest sense as the wires come off the centerpiece like an "X" and help guy the mast. I have a 1:1 balun for the transition from coax at the feedpoint. It was a little bit of a challenge to get it tuned, but I can work the design bands without the tuner.

  On the same mast is an 80M EDZ that is basically a 343 foot open wire fed inverted V at 52 feet that allows me to work all the rest of the bands from 160-6. Not only is this a solid performer, I had a pretty good time making the open wire feed line as well. I am working on a standoff to get the centerpiece away from the mast a little bit further as well.

  The latest antenna project I am working with is a Small Transmitting Loop or Magnetic Loop

  The picture is just a quick test antenna that is a 5 ft loop made from 3/8" copper tubing with a borrowed vaccum variable cap from my link coupled tuner for testing.

  I have since swapped out the vaccum variable for a small 20-250pf air vairiable. I am using it as a dedicated digital mode antenna as I can tune it for the digital portions of 40/30/20 with 15 watts. I can run it up to around 25 watts before I have to worry about the cap arcing, but it is doing pretty well at 15 watts.

  I have been running some A/B comparisons vs. the dipoles and the vetical and, using PSKReporter to check the send/receive reports, it really does a decent job with 15 watts out.

  Aside from building antennas, which I just can't seem to get enough of, I have started to homebrew some other gear for the shack. Some of these projects include:

Link coupled tuner for the EDZ

  Through a lot of research and I found several schematics and decided, due to parts available, to try the K1JJ design. It is very simple and only has one capacitor and the coils. The benefit of this design is both the capacitor and the antenna are tapped so the range is outstanding. The one I built will tune the EDZ on all bands 160M-10M with a 1:1 SWR on most and a 1.3:1, being the worst, on 20M.

  Now that the testing is over I need to do a little work fixing it up and make a better bracket for the capacitor.

  I also buit/bought a panadapter set up for the shack using a cheap DVB-T dongle.

  After reading about these and research on possible uses, I bought a DVB-T dongle and HF upconverter and built a front end protector/ isolation T/R relay. I have it tapping off the homebrew radio/antenna selector switch I built so works with whichever rig I am using.

  I also connected HDSDR through a virtual serial port so it tracks along with the rig through the CAT control. I am pretty sure this will lead to more SDR fun for me in the future as the capabilities of the less expensive gear continue to increase. After all, learning and experimentation is my favorite aspect of this great hobby.

 

Looking forward to seeing you on the bands!
