post mortem for John Moyle Field Day Contest 2019

the plan was to go to Mt.Lambie to operate the contest from, however, the weather was a let down, as it rained  all the way from Sydney to Lithgow and onto Mt.Lambie. In fact the whole of Mt.Lambie was engulfed by low cloud, as were any hills around Lithgow area.  So a plan of action was required, checking the BOM radar it was showing it as raining in Bathurst, that meant the alternative plan of going to Mt.Panorama was out of the question.  We noted that no rain showing on the radar to the north, ie. up to Ilford, Rylestone area. Started driving towards Ilford, as we progressed the weather improved, by time reaching Ilford it was mostly sunny, the road was dry. Once at Ilford, turned onto the Sofala road and headed along looking for a high location suitable for VHF and above, particularly for microwave bands.

Found a high spot just a few kilometres north of Sofala, about 860 metres ASL, QF46ux, an all open hilltop, setup off the road, then noticed the wind was suddenly increasing, by time we were ready to make contest contacts, the wind became so strong it was knocking over equipment and trying to blow away out portable gazebo.  Meanwhile, over on another mountain to the south west, Dave VK2JDS and Matt VK2DAG were now getting wet from a  rain squall and had to pack up all their equipment.

This lead us to the decision of packing up and go look at other potential mountain tops for future contests and microwave field days. One spot was up on the Old Ilford Road, QF46vx, this road runs along a ridgeline, all well above 1,000 metres ASL,  better than the location we stopped at on the Sofala Rd. We will keep this location in mind for future events.  Another potential area was at Wattle Flat QF46uu. we travelled back to Bathurst, then headed east, detouring up through sunny Corner and Dark Corner looking for potential high locations.  A really good spot is at a  farm at corner of W.Mitchell rd and Dark Corner Rd. (QF46wp). This might worth stopping and asking if we could use their paddock.

After returning to highway, we passed Mt.Lambie, it was still shrouded in low cloud. We proceeded onto Lithgow, purchasing some dinner and heading up to Hassans Walls lookout to check this as a potential site. Aft this heading up the Chifley Rd, stopped at Dargan next to railway line,  could hear 439.700 repeater from Nelson Bay,   also the Somersby 6m, 2m & 70cm repeaters are all 60/9 signals even though it pouring rain and sitting in cloud. It poured rain all the way back to Sydney.


Note: in this picture, you can see the ridgeline in the background of Old Ilford Rd.

Summer VHF/UHF Field Day Contest - 12th / 13th January 2019

almost end of 2018 and just realised that it only two weeks until the 2019 Summer VHF/UHF/SHF Field Day Contest.   I missed the Spring Field Day for 2018, so more effort required to ensure I go portable to operate VHF through SHF, obviously a mountain in the western side of Blue Mtns. The plan is to go Saturday morning setup for 12noon start, do 6 hrs stint will be enough. Not serious to win, it's about just getting out portable to give out some numbers to others and build up microwave skillset. I got everything for 6metres and above, but primary focus is on microwave bands.

DX Report 19th December 2018

another opening to ZL yesterday from VK2, on 2metres  and FM broadcast band across Tasman Sea.
ZL2WHO beacons heard into Sydney and Newcastle areas. Interestingly, Hepburn didnt predict much tropo for the day.
For the day before (18th December) good opening  on 2metres between VK4 and VK5 a few contacts.

VHF, UHF and SHF wide band LNA's

I bought a few of these cheap wide band LNA's that run off 12v or 5v, with varying Gain and Bandwidths,  at a few bucks each,  they good for playing and experimenting with in terms of weak signal receivers for VHF, UHF and SHF.   Good selection around on Ebay and AliExpress.

RF site testing at QF46qu on Easter Sunday, 16th April, 2017

Doing some site testing at a friend's farm at QF46qu at Gowan, north west of Bathurst NSW.
my GPS estimated 950m ASL mostly cleared, with almost 360degress of clear horizon, good for playing radio. As it was Sunday morning I made use of the fact that the WIA morning broadcast was one reason to listen for it on various known frequencies including 2metres, 70cm and 6metres.

I could hear 146.775 Newcastle, 146.725 Somersby, 146.850 Maddens Plains, 146.975 Knights Hill,  53.650 Maddens Plains, 146.950 Mt Ginini.   Could not hear anything from Dural. This was using quad band radio (TYT TH-9800) and quad band vertical from the vehicle. Should be much easier with some yagis up a mast.

Looks to be excellent site to run microwave equipment from (23cm and upwards).

 a little bit of trees to north east,
 looking to north coast & mid north coast NSW, all clear.
 looking to Newcastle through Sydney, all clear
Looking back to Bathurst
 Looking to south and VK1
Looking to VK3 & VK5 all clear.
Looking west, a couple trees
Facing to north west, highest point where these pine trees are.
 Looking north, a few sparse trees, but nothing Roundup or a chainsaw can't fix
Good flat area, for parking, camping, whatever.

Field Portable QF46pu Gowan NSW

For Easter weekend, April 2017, was visiting QF46pu, to get on 2m,70cm, and 23cm AE nets in the mornings. Did some testing on 23cm gridpacks and dish against the Dural beacon 1296.420. Did not hear any other 23cm beacons.
 This is small gridpack looking back towards Newcastle.

 This is a larger gridpack, certainly slightly better than the small gridpack
 IC-910H was hooked up to 2m yagi, 70cm yagi and 23cm  running from solar panels and batteries
 The 3metre diameter mesh dish with 23cm feed, aimed towards north coast NSW
 Smaller gridpack aimed at Sydney Dural 23cm beacon (approx 180km)
Looking towards Melbourne in the gap between trees
 Looking toward VK1, worked VK1KW and VK1DJA on 2m SSB
 2metre and 70cm yagis

I took 3.4Ghz and 10GHz  but did not get time to flash it up.

Best activity was working Compton VK2HRX who was SOTA portable up the Warrumbungles, worked him on 2m SSB, 70cm SSB and 1294.000 FM

Aiming to the right of the big tree to work Compton VK2HRX/p at QF48mr SOTA spot CCW001 a distance of 209km, not bad on 1294 MHz FM as Compton was using a 1w handheld.
and screenshot from VKLogger

For next time,  remember take my portable generator.

GippsTech symposium 2016

this coming weekend is GippsTech 9th/10th July at the Federation University in Morwell Victoria.
Lots of  good technical discussions to listen too, meeting microwave gurus and top it off with some on-air activity on sunday afternoon on 3.4 Ghz

some new beacons

VK1RSB   Canberra
144.410     On-air, temporary vertical antenna  (FSK)
432.410     constructed , awaiting installation   (FSK)
1296.410   constructed , awaiting installation   (direct CW)
Dual "big wheels" horizontal antennas planned will be used for all 3 x bands.
 
VK2RSF   Nimmitabel
144.414    On-air
432.414    On-air
1296.414  planned 

of most interest to me is the  23cm beacons, these will be good for test references from Sydney.
