Meteor Scatter  and JT65 HF digital modes

I have become active on meteor scatter using digital software.  I highly recommend this mode to try as it can give some amazing results.  Information can be found and free software download at the following websites:

http://www.vhfdx.de/wsjt/#Download   WSJT digital software download site.

http://www.ykc.com/wa5ufh/Help/WSJTPrimer.htm#Level Low  Primer on getting started

http://www.pingjockey.net/cgi-bin/pingtalk  Coordinating site for contacts

East Tennessee DX Association Website:  www.etdxa.org

For meteor scatter the main freq are 144.140 or near and for 6m it is 50.260 or near.

I am now also operating JT65 HF mode.  This HF digital mode is closely related to the popular JT65 moon bounce software.  Using this very weak signal mode it is possible to obtain some amazing results on HF using low power, 25 watts or less on the following freqs:  1.838, 3.576, 7.076, 14.076 all USB mode digital.  I am using the SignaLink USB interface and the Ten Tec Orion II on this mode at 25 watts.  Go to: http://jt65-hf.sourceforge.net/ for info and download.

You can download the software to decode the digital signals for meteor scatter from the following website: http://www.vhfdx.de/wsjt/#Download

Once you get the software installed on your PC you will need to connect your PC sound card output for transmit and input for receiving to your radio. To do this you will need to purchase an interface. I recommend the following company and website:


I recommend the SignaLink USB unit. Purchase the one for the rig that you are using.   Other companies make interfaces also, check the ads on web and amateur radio magazines and catalogs.

Follow their guidelines and just hook up the cables and interface box between your computer and radio. Set the sound levels both in and out using your sound control functions in Explorer and you are ready to try meteor scatter. Coordination for all of the contacts occur on the following website: http://www.pingjockey.net/cgi-bin/pingtalk

I have become active in the last several years in emergency radio communications via ham radio.  I have renewed my membership and updated my training in the ARES organization and also have joined a local ham group called METERS,  Middle East Tennessee Emergency Radio Service, www.metersinc.org

Knox County, Tennessee    --    Club Call KC4EM

I highly encourage all ham operators to seek out their local ARES organization and/or other ham emergency group and become involved.  We all hold our ham license as a part of our capabilities to aid in emergency communications for the nation and not as just another hobby.

I have recently became more aware of a possible threat to our country by an Electro Magnetic Pulse, EMP, attack.  I recently read a novel by William R. Forstchen, "One Second After"; which is a fictional novel about an EMP attack on our country and the resulting disaster to our country.  I have written an article about this topic on this link.  One Second After.....

I encourage you to go to Dr. Forstchen's website, www.onesecondafter.com,  to learn more about this.


Ten Tec Hamfest of each fall is very well attended.  Your Website Editor, WA4YRK attended.  There were over 100 hams setup in the tail gating part.  Ten Tec was showing off both the new HF Orion and the new Argonaut V.  Many active VHF/UHF hams were in attendance and lot's of gear and antennas were for sale.  

The following are some photos taken at the hamfest:

Southeast VHF Society Conference, April 26-27, 2002 in Oak Ridge, TN.  Garden Plaza Hotel.  

Your VHF Ham Radio.com  editor, Dave Garner, WA4YRK,  attended the conference.  Friday and Saturday featured antenna and preamp measuring, business meeting, and seminars on moon-bounce, meteor scatter work, antennas and dish polar mounting.  Those in attendance enjoyed a diverse program of presentations from moonbounce, (EME), weak-signal and antenna experts plus a bit of digital signal
processing. Presenters covered operating and station-construction
techniques for all the bands between 50 MHz and 50 GHz. Highlights
included Al Ward, W5LUA, detailing how he and Barry Malowanchuk, VE4MA,
completed the first-ever Amateur Radio 24-GHz EME contact. "47 GHz is
next!" Ward predicted. L.B. Cebik, W4RNL, showed some improved topologies
and element spacings that achieve substantial reduction in the side and
back radiation of Yagi and log-periodic arrays. Paul Wade, W1GHZ, told the
gathering about his design and use of periscope antenna systems and how
they help him get 10-GHz contacts. Dexter McIntyre, W4DEX, won the coveted
K4UHF Award. Conference Proceedings are available from ARRL for $20 (order
item 8683). Visit the ARRL on-line catalog <http://www.arrl.org/catalog/>
or call toll-free 888-277-5289. Part of above report compiled from ARRL Newsletter.

The sessions were excellent.  The turnout was over 100 hams, who represent some of the top VHF/UHF weak signal operators in the country.
