6m EME With 3 elements (RX only)

Today 10 Sept. 2010 we have very good EME conditions (Not like the last days) but still GOOD.
I am receiving Lance W7GJ with my remote (RX only system) with 3 elements beam home made (DK7ZB).The location has a very good take off,overlooking the sea and of course very good ground gain. I am using the Kenwood TS-480 without any antenna preamplifier, antenna 3 elememts,10m of ecoflex-10 coaxial cable and the WSJT-9 program in JT65A mode.
I hope to copy Lance as well from his upcoming 6m EME DXpedition from Fiji Islands (3D2LR , in RH92cq) .
Any contribution to help Lance W7GJ, for this rare DXCC 6m DXpedition are welcome.
Please use Pay-pal to : w1jj@aol.com

Once again the very nice program developed by JOE, K1JT, the MAP65-IQ connected together with LINRAD and the RFspace receiver SDR-IQ, with the Hamtronics 2m Converter, you can see a large portion of the 2m band for EME qso's. Also a nice program developed by Rene, PE1L with the name Livecq 144 you can upload in the web all the stations having CQ or QRZ before the call and no other info.
With the live cq www.livecq144.com you can check the activity in EME, the propagation, the trafic etc.

First RXing test on 129.10 DCF39/49

Today 24 Jan 2010 made my 1st attempt to RX on 137 Khz.
There is a very strong station there located in Germany with the call DCF 39 or DCF49.
The DCF QRG's are 129.10 and 139.0 Khz. Transmition mode 200 bps ASCII (8E1) with shift 340 Hz.The DCF has on both QRG's a steady carrier and at about every 10 seconds send a message in FSK mode. The locator of the DCF is at JO52WG near Magdeburg - Germany.
The antenna is a vertical monopole 324m high with EIRP (Effective Isotrope Radiated Power) 40 KW omnidirectional. In the spectran you can see the shift keyer and with Mix-W you can see the text. DCF is a very useful tool to test your antenna - Receiver and to tune filters and preamplifiers for the 137 Khz amateur band.

Here is what you can see with the MIX-W program.
The station DCF39/49 trasmit on 129.1 and 139.0 Khz.

Here are the MIX-W settings to decode the DCF 39/49.Shift 340 HZ with Baud rate 200 and character set at ASCII 8 even parity and Inverted mode.

FT2000 as receiver in USB mode - antenna 300m beverage.
