630-meters at Field Day 2015: The wrap up

– Posted in: 630 Meter General Topics, 630 Meters

Updated 7/02/2015

In spite of the best efforts of the sun, the transmission of Field Day greetings during the 2015 event by 16 MF and LF stations was well received by operators across North America.  Reports are still coming in at http://w5jgv.com/enterlogs.htm so if you have a report, please submit what information you have at the above link.  No report is too small.  Even if you just listened for signals and heard nothing, please let us know.  You can even email me directly on the contact page with your report.

If you have read this far and have no idea what was happening on 630-meters during Field Day 2015, start here.

I’ve had a few operators send me pictures and videos so I thought I should share some of them below as a retrospective.  Please check back over the next few weeks as I will add items as they are provided to me.

Below is the XIQ remote grabber showing a faint XKA CW line at 472.5 kHz, XIQ at 474 kHz overloading the SDR, XXM on WSPR at 475.710 kHz, and XSH/7 running CW and PSK31 at 476.3 kHz

Newly granted Part-5 op on 630-meters, Mike, KA8ABR / WH2XUR, reports the following and sent the following pictures:

“While attending a Field Day event at an old VOA site near Cincinnati I was able to configure one of the antennas to receive MW signals.  I tried to listen in to see if I could find any stations running around 475 kc.

The only signal I heard was from Eric’s beacon (WG2XJM) near Meadville, PA.  His station is 278 miles away from our site near Mason, Ohio.  I listened in around 3:00 AM EDST and found his signal to be 599 on a Yaesu FT-1000 being used on Field Day.  Eric’s signal had some QSB, sometimes fading into the noise, but while I listened for about ten minutes, the signal was clear and easily heard 90% of the time.

The antenna was an 80 meter dipole at 50 feet fed by about 125 feet of window line.  For amateur work, this was fed by an old link-coupled tuner and while tuning medium wave I used a parallel tank circuit connected to the twin feeders tied together at the feed point.  The old VOA site has lots of copper in the ground yet, and that was used as a counterpoise.

Being situated about a mile from the transmitter site for WLW, a clear channel, 50 kW station on 700 kc, interference can be a big problem.  This leads me to believe that Eric’s signal was rather strong.”

John Molnar, WA3ETD / WG2XKA, helped the Green Mountain Wireless Society in Rutland, VT set up their antennas so they could listen for his 630-meter signal.  He used a drone to raise ropes over a light standard so that  antennas could be pulled up later.  More pictures on John’s  blog and there is possibly a video forthcoming.


And we will end with the last 45 seconds of WG2XIQ’s 7 minute Field Day message (with audio)


I will add to this collection as I receive content.
