ROS 16/8/4 HF

Francesco Picconne YV4GJN sent this screenshot of his first QSO with Australia in ROS with VK2CBL at 1:00 UTC. He was using ROS4 and 70W to a Carolina Windom short Antenna and he could be decoded at Twente SDR too. Congratulations!

New African Record on 30 meters, this time a QSO of G0NBD with ZS6ANZ of 9438 kms using 20 watts  and 35 feet of  scaffold pipe    (home made vertical) . QSO started with 8 bauds (Marge 5 dB) and they finished using 4 bauds for more guaranties. Congratulations and thanks for the report. 

Recieved at Twente SDR:

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.

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.

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.

Nice QSO reported by Graham G0NBD on 20 meters,  25w Antenna  35 ft  vert.  He was transmitting with 8 bauds, and PY6HL was using 16 bauds.
