Post mortem of WIA Spring Field Day Contest 2019

Roger VK2ZRH  and myself operated an  8hr section of the contest from Gowan QF46pu, which is n.w. of Bathurst in NSW. On a hill at 920m ASL.
We took gear to cover 6m, 2m, 70cm, 23cm, 9cm and 3cm, all yagis for 6,2,70,23  and panel for 3.4GHz and dish for 3cm. 
We chose this location on basis of working local microwave stations of VK2CU and VK2DAG who have all bands up to an including 122GHz versus trade off of operating back towards Sydney to pickup on stations on the low bands from Sydney and coast.
We had a few contacts on 6,2,70 with various locals from Central West ARC, but the long distance contacts we hoped to get didn't happen,  eventhough we receiving fhe VK4RHT Atherton Tablelands 52.280 beacon coming in solid for hours, plus hearing VK2RWI Dural 2m, 70cm and 23cm beacons, which proved antennas are working, we just didnt hear anything.
What i learnt from this is we just can't try and work everything, its either go to Gowan to work microwave bands, or locate closer to Sydney for the contest, i.e. up in the Blue Mtns, i think it better do special trips to Gowan just to do microwave activity,such as MAD 23 on 23 days and operate from different hills to test our abilities at operating microwave portable. On side note, one of the locals from Central West, Doug VK2XLJ operated portable from Mt Canobolis and worked a ZL on 2m SSB as part of the contest, thats pretty impressive as tropo path from ZL rarely extends inland or over the Great Dividing Range.

post mortem of WIA Winter VHF UHF SHF Field Day Contest 2019

I forgot to do a write up, or I started but never completed, anyway, I did actually enter the contest, I operated from QF46pu, others who were there or nearby (QF46qu) were VK2CU, VK2DAG, VK2ZIW, VK2ZRH and VK2JDS.
I operated 24hrs segment. Bands used were 6m, 2m, 70cm, 23cm, 9cm, 3cm,  24Ghz, 76Ghz, not sure if we did 122GHz in the contest itself,  but we did spend a fair bit of time experimenting with 122Ghz on that weekend across the 3.8km void between hilltops.  Also did  some 4WDing around the two farms and taste testing some red wines at night following the roast pork cooked in a wood stove.
Overall, it was more of a microwave tuneup get together, than a serious go at contesting.
