I went up the mountain for a few days (18th to 22nd April) to do some DXing, the intention was to do some HF, VHF, UHF and SHF, but mainly only did VHF and UHF, being 2m & 70cm SSB for AE activity. EME was out as the moon in the wrong place/time. Made some contacts with the guys in VK1 and far south VK2, mid-north coast VK2 and VK3. No luck with VK4 contacts this time. The first morning was difficult with high winds, trying to keep yagis still and the wind howling made listening to weak signals very difficult.
Did manage to do some more work on the mountain top shack, by adding some more desk and shelf space, to spread out the equipment, plus a place to sit the notebook. Also shuffled a couple antennas around. Did some testing of receivers for 2 & 70 against the Dural 2m and 70cm back in Sydney, the 4 x 8el yagi stack versus a single 8 el yagi didnt seem to make much difference, as expected. At least the Kenwood TR9130 and TR-9500 are receiving well in comparison to the Icom IC-910
We reviewed the mast/tower options, Dave wishes to get a triangular section tower up with a electric rotator fitted so we can swing yagis around without using the Armstrong method.(hihi)
Also went to Macquarie River crossing down near the Bridle Track to catch up with Ashley VK2XSO who detoured down from the north via Hill End to pickup some TRS80 gear for his collection, before heading back towards Narrabri for a job the next day up at Mt.Kaputar.
Also caught up with John VK2EJM and Jeremy VK2FLE who came to visit the farm from Orange. Also had Colin VK2BCC stop in on the way to Orange the next morning to see what we been up to on the mountain top. Discussed Bob VK2ABP/VK0BP (SK October 2012) in depth and also about Bob and Colin's experiences in Antartica.
The background photo used on this blogger is in fact a pic of Bob VK2ABP/VK0BP up on the mountain top, a place he visited frequently, both in setting up and operating from.

Solar Cycle 24
Solar Cycle 24 not looking real good ... I think this certainly points to the fact that there is little hope for Cycle 25,

I think the move to microwave terrestrial DX and EME looks more inviting everyday.

23cm repeater
a new 23cm FM repeater went live here in Sydney recently, VK2RWC on 1273.200 o/p 1293.200 i/p a top of a high building in Chatswood. It is co-sited with aanother WICEN 2m repeater on 147.150 o/p 147.750 i/p and requires 91.5 Hz CTCSS tone. Both giving good coverage.
It must be 10 years since we had a WICEN repeater at Chatswood. The site is still missing its 70cm counterpart, but that is on its way, expecting to be on 438.350 o/p 433.350 i/p and presumably a 91.5 Hz CTCSS requirement.
the most important fact of all this was that we now have another 23cm FM voice repeater for Sydney, to compliment the WIA 23cm FM voice repeater at Dural on 1273.500 o/p 1293.500 i/p, which unfortunately is suffering issues due to broken antenna, one day it is good, the next day it can be near impossible to access, depending on which way the wind blows.
Other 23cm repeaters ? some more that are planned or under construction in NSW:
1273.100 / 1293.100 VK2RZL for Westlakes ARC, in the Sugarloaf area near Newcastle
1273.200 / 1293.200 VK2RPW for Walcha area.
1273.300 / 1293.300 VK2RBM for Blue Mountains ARC , west of Sydney
1273.300 / 1293.300 VK2RPL Mt Nardi, Lismore area
1273.450 / 1293.450 VK2RRR at Razorback in Sydney's south west (Camden/Picton area)
1273.700 / 1293.700 VK1RJB in Jervis Bay on the South Coast
plus some D-Star rptrs exist on 23cm too.

new APRS digi
I bought and supplied a TinyTrak TT4 as a digi for VK2JDS-1, it covering the area well, plus identified issue with VK2ABP-1 digi, a poor Rcvr, we'll sort something out that in the future. Probably a better location for that equipment one day.

DX Farm October longweekend post mortem
Last weekend went well, the trip up yielded good APRS track all the way to the farm via APRSDroid on my phone, as Optus has improved 3G coverage at Monkey Hill, so now have 900 Mhz 3G signal along the road and now have data feed from the farm, as opposed to only having coverage from top of the mountain previously, as in the past, we relied on Mt Canobolis for Optus coverage. Telstra signal already there, so not an issue. Did discover there is no Vodaphone coverage on the farm, except for the mountain top.
Mt Canobolis also provides 2100 MHz Optus 3G service, could run a directional yagi from the mountain top if required to access that service, otherwise, it is just the 900 MHz from Mt Aquila and Monkey Hill that provide 3G feed whilst at the farm. Anyway, this time, we had good data service so I can access the vklogger and other DX clusters and of course email. Telstra run 850 MHz 3G service from Mt Aquila and Monkey Hill too. I forgot to run Speedtest on both services to see how they compare. As for Bathurst, too many high ridges in between, so no service from Bathurst.
APRS on RF, Sydney to Lithgow fine, but limited coverage past that, next to nothing in Bathurst, as Bob VK2ABP's digi suffering interference and is deaf. Once the new APRS digi is on the mountain we should be good.
First day, did some EME chasing, worked Brett VK2CBD on 1296.070 on JT65 via the moon.
The farm now has antennas on the mountain top covering 160m through to 23cm, predominantly horizontal polarised for DXing. Made use of the 80m loop for 80m and 40m, mainly sitting on 7045 LSB to keep in contact with club members back home, such as Rob VK2MZ, Horst VK2HL/m, Ted, VK2FLB, Greg VK2VGM/p
2m SSB, missed the Sunday morning AE net on 144.200, as we slept in, but on the Monday morning did get up early enough to get on the AE net on 144.200, worked a good handful of stations, Rod VK2TWR in Nimmitabel, Ian VK1BJ and Rob VK1KW in Canberra, Col VK2KOL in Sydney, Colin VK2BCC in Blackheath, Gordon VK3EJ in Cobram and Mark VK2EMA in Tottenham. This time was running close to 150w into the 8el yagi via 10m of coax, last year only getting 40w. Also attempted a contact into VK5 without success.
It was very breezy and had a hard time keeping the yagi pointed in the correct direction, the issue there was that the TH3 HF yagi is above and gets pushed around by the wind. Damned cold in the morning with -3 deg C, at night it was down to 4deg C, making it hard to keep warm in the tin shed.
Other times, gave some calls out on 144.100 but nil activity. Did not get around to trying 432 MHz.
Monitored 50.110 MHz, but quite dead. Nothing on 52.525 MHz either. Although 10m was flying.
We spent a good part of the time fixing an old car and getting it running, taking the girls driving around the farm, motorbike riding, etc. Thanks to Carmel VK2CAR for providing me with a battery to go in the old car.
Looking forward to next visit. I want to build a 1296 MHz Xvtr to do some terrestrial DXing for the mountaint top.

upcoming activities
Building a APRS digi to go out at the farm, a TinyTrak4 for 145.175 MHz, this should provide good coverage for Hill End area and back towards Bathurst, hopefully complete by end of October.
Visiting the farm for October long weekend, will do some terrestrial DX for VHF, UHF & SHF
Seriously thinking about installing a 70cm rptr for the farm too, to fill in those dead spots around Hill End, Turon Rriver, Macquarie River, Bridal Track, much the same coverage as the APRS digi will provide. Except using a binary array for the 70cm, a little more gain, it should provide coverage up to Coonabarabran, maybe Dubbo. This idea has been on and off for probably 15 yrs now, but put it back on the drawing board recently due to lack of coverage from other local rptrs.
I'd also like to get to the farm for a VHF Contest this summer. Always hard to find the time, but its almost 2013 and the last of the good sunspot cycles, so got to make the best of Six metre DX across 2013-2014.

Echolink node back on air
after two issues, one being interference in March, which has now been resolved, followed by the PC crashing, (do not use Windows XP for mission critical applications) we have the Echolink Node 1494 back on air. Currenlty on 2m simplex, but need to relocate it to 70cm simplex, which is in progress, plus a better antenna.

Echolink node 1494 update
setup the alternate PC for my Echolink node, different type of motherboard and different type of built-in sound card. Had it all running last night, RF audio coming into the node from the radio (Line-In) port now sounding much better.
six metres FM activity
some good E's activity on the weekend, after the WIA broadcast on Sunday mornimg there was talk of 6 metre opening to VK3, tried out the repeaters and found these repeaters coming in with good signals,
53.550 VK3RMH Melbourne 30km NE of MelbI called on all of them several times, but nobody to be found, but I did work vk3NUG and VK3ALZ both in the Gippsland area on 52.525 simplex. Heard VK3NUG again several times later in the afternoon on 52.525
53.600 VK3RMR Gippsland Aberfeldy, nth of Morwell
53.675 VK3RAD Melbourne East , this has a electronically generated voice ident
53.725 VK3RGV Mt Wombat near Shepparton

Echolink update
My Echolink node is back on air after a lengthy absence, ran some tests, realised the noise of the incoming audio from the radio is still noisy, did some testing to isolate the source, I thought it was a noisy receiver, but after testing realised it was the Line-In port to the inbuilt sound device of the Dell PC, I adjusted the audio levels from the Windows drivers and I can vary it.
Not really a problem, as I built a new PC up (more precisely, I stripped down an old server, to
make it run 24x7 with minimal power usage, with extra fan, so it will run cold) so hopefully, the audio device in it will not have internal noise issues as the old Dell PC had.
Hoping to build the new PC using SVXLink (a linux based Echolink server).
Also, I eventually uploaded the latest version of Echolink client app for my HTC phone, now there is athe option for headphones or speaker, so I can now use the headphones for working the Echolink app from the phone. I was getting desperate and thinking I would have to get an iPhone just for the sake of working Echolink from a mobile phone.
Speaking of mobile phones, looking at my next replacement, heavily considering the Samsung Galaxy S II (Android based) for a phone and a Samsung Galaxy 10.1 Tab for a tablet PC. Yes, the iPad, iPhone and iMac are very nice devices, but I just don't like the idea of being told what you can and can't do when it comes to those devices, or being bound & locked in to the latest Gen-Y fad, I prefer flexibility. I like the idea of Linux and Android where the tools are available, it's up to me if I want to change things. (back off the soapbox)
Finally, I understand the concept of the Echolink Proxy, I was led to believe that it would let someone run two Echolink nodes from the one IP service, but after reading into it, that is not the case, so that squashed the idea of multiple nodes (for now). The idea for the 2nd node was to have a 6metre FM receiver scanning 52.525 plus all the repeater frequencies, now this could have been fun for someone interstate during 6metre E's season, you could be calling on 52.525 or one of the 6metre repeaters in the Sydney basin and hear yourself coming back through the Echolink connection, handy for testing propagation when there is nobody listening.
