| 30.03.03 | Early - 12pm | Noticed this condition from very early morning (1am) and lasted a very long time. It appeared to be only strong Super Refraction but readings from AREPS showed a Duct present over my QTH. Confined only to VK3. | Exceptional Simplex contacts made were : VK3VSW in Geelong 384km; |

| 09.04.03 | Morning | Into VK3, parts of VK5 (Mt Gambier area) and some VK2 | Weak signal from Mt Gambier |
| 12.04.03 | Afternoon | An interesting phenomena. I believe this to be an Evaporation Duct. Caused after a down pour of rain the previous night and morning, followed by a warm mid morning and afternoon. This causes the air from ground level up to a certain distance above ground to be saturated with water vapor, this causes a trap. | Arart rptr useable. 3ANW, 3XDP, 3FIQ, 3DSF, 3HEN, 3DNH, 3GOM on simplex |
| 14.04.03 | Midnight | This peaked for only around 2 hours near midnight on Monday night. Mildura S7, Robinvale S8, Swan Hill S7, Canberra S8 | No stations on air at this time. |
| 20.04.03 to 23.04.03 | Mainly in the mornings of these dates | This started the Sunday of the Easter weekend. Very good signals into VK3 and SE VK5 - Mt Gambier and Naracoorte. Stations in the far SE of the country around Melbourne and Gambier had very strong sigs from West to East, a few stations heard the Esperance beacon. Southern stations able to work into VK7, from Melb and Gambier. Weather charts | Simplex with 3VSW, 3ANW, 3KOS, 3FGY, 3GOM, 3XDP, 3JGL |
| 1.05.03 | 6:40pm to 2.00am 2 repeaters stayed in until 7:30am | A long awaited VK5 opening today. Most repeaters were copyable at least, some were up to 40db+.

| 4.05.03 | 7pm till late | Mainland to Tassie Duct, I was unable to work any VK7 stations but did hear others working them such as VK3ANW in Kyabram to VK7LCW simplex of which I could just hear LCW with my radio on CW. | Well done on the contact Noel |
| 30.05.03 | Evening | Unfortunately I only caught this one on the mobile radio as my home antennas were in Horizontal. Heard a station in Bendigo and Bathurst into Canberra repeater. | No Simplex |
| 17.06.03 to 20.06.03 | Hung around most of the day and night | Interesting conditions in that its gradually built up on the 17th and stayed in most of the time, seemingly peaking in the warmer mid mornings and evenings before night fall. 70cm was quite impressive with a number of Melb 70 cm repeaters being full scale!
