Sunday Australian FreeDV Net - 20 stations

An excellent rollup again this morning with some interesting conditions that seemed to improve and then decline during the net. 

At first there was very little fading here but later I saw this interesting effect pictured here.

Another observation was that sometimes the measured SNR does not match up with the quality of the recovered voice. Sometimes SNR is very low, even negative, and speech is perfect. Other times SNR is good but speech is not good.

VK3EMI commented that he had trouble hearing people when SNR was -7dB or below! Fair enough I thought.

Stations participating - not all heard - VK2VCO, VK3BRT, VK3CKY (portable), VK3JCO, VK3KEZ, VK3KQT, VK3SRC, VK3YV, VK5AG, VK5KVA, VK6POP, VK5AV, VK3UBK, VK5COL, VK3EMI, VK3PCC, VK5LN, VK5GY, VK2DWG and me VK3TPM.
