Dr. Livingstone, I Presume?

28 July, 2010

Great QSO on 30 meters across Africa (8500 kms).

With ROS Mode the History of Henry Morton Stanley and David Livingstone had been some different 🙂

Congratulations to ZS6ANZ, UT3WW and UT2GA.

New Zealand at Twente SDR on 14112

At 15:05 UTC, ZL1CDP has appeared on my RX screen listening at Twente SDR http://websdr.ewi.utwente.nl:8901/

Perfect copy with a S/N of -23 dB, Fade Marge only 3dB  using ROS8/2250.

In this case using ROS16 the contact had been impossible (Marge 0 dB)  so, for long distances and low power, the best options are ROS8 or ROS4.

New record: 19411 km!! 30W + dipole

23 July, 2010

Great QSO of EA3FHP ( http://radioclubvic.servimedia.biz/) with Pete, ZL2AUB using 30 watts and a simple dipole. They was using intelligently 8  bauds instead of 16 bauds

Note:  The record is in distance, not in Power.

New record in distance: 18961 km!! 599

13 July, 2010

 As usual in ROS, 18961 km with 100% copy.

New record in distance: 18660 km!! 599

10 July, 2010

New record in the EA8TL stats on 20 meters. This time with Len VK2CBL at Sidney at 18660 km from his QTH. 599 in both sides. 

 S/N: -3 dB . It means 23 dB of Fade Marge with ROS8. VK2CBL could have reduced 40 times his power to achieve the same result: 100% error free.

Congratulations to Len and Jorge for this Great QSO, but try decrease the power when you use ROS. This is not PSK31.
