G -> VK Long Path QRP SOTA Activations

13/09/2014
I decided to go up to local Walton Hill - G/CE-002 to try to work the VK land early in the morning inspired by Carolyn G6WRW, Mike 2E0YYY and others in the SOTA reflector.

I left the house at 5.05z and after 15min drive and 5min walk to the summit - I was in business by 5.45z. Temp was 12C, foggy but no wind whatsoever.
Over the last few days there has been a CME and plenty of sun activity so early in the morning the conditions were depressed..... My expectations were low!
After 45min, things started to pick up - I was following what others were doing on the summit - Mike 2E0YYY/P and Roger F5LKW/P via SOTA lite spots web on my mobile.

At 06.49z I QSYed 1 KHz up to contact Roger and made a S2S - F/CR-204.



10min later I heard VK3...VK3.... Ron VK3AFW heard my call and came back to me. I gave him a 579 - he was a good signal - 100Watts on a 4-el beam at 13m height. He gave me a 539.
Later Ron confirmed on the SOTA reflector he was beaming towards the Long Path - that is 23000Km at 250degrees from Walton Hill.

At that point signals became very loud and the band was in great shape... we exchanged 599+10 with Guru EA2IF in Pamplona - both on QRP.


Station:
MTR v2 - 30-20-17m - 5Watts
EFHW - multiband linked & Mountain Tuner set up as inv L - 9m vertical wire & 1m sloping down - 20m
band. tuner about 1m above the ground.
10m pole
Mini paddle
LIPO 3S zippy 1000mAh 25C

G/CE-002 Walton Hill -  06.15z

Station: MTR v2 ... calling CQ on beacon mode

Summary:
22 QSOs, 12 DXCC, 1 DX with VK3, 1 S2S

I went back to Walton Hill early in the morning to try to work some more VKs via LP and S2S.
I started a litte bit later - 06.45z... Brilliant WX - warm and sunny. Raul, one of my friends from Laguardia in EA1, acompanied me and enjoyed some reading in the sunshine whilst I was at the key.

Having seen the good results that Mikel EA2CW and Marcial EA2BDS got with their dipole at 9m earlier on the week, I decided to take my homebrew 44' doublet. I used the Commander Compass app on my iPhone to aim the broadside of the doublet towards VK land. - 250deg SW/W

I started on 20m. At 06:48z, Tony VK3CAT returned my call. He gave me 33N, he was a 55N on my end.
About 15min later, Ron VK3AFW came back to me with a 55N, he was a stronger signal than the last week with the EFHW
It was a busy morning, with a lot of callers and many familiar callsigns. I did QSY to try to work Gerard F/VK2IO/P and Gerald F6HBI/P on 20m but they were on the null of the doublet and/or skip and could not hear them.

When I swapt to 30m, I rotated the doublet broadside about 20-30deg towards the North in order to aim towards NA, but I run out of space. I did not want the nylon rope to run over of the walking path as there was plenty of bike and horse riders around.
At 07.43z, Guru EA2IF/P called from EA2/NV-040 on 30m and made the only S2S of the day. 

I swapped to my HB1B to work 40m and worked a few other stations.
The band was in great shape. Andreas DL6AP/P called me from GMA DA/ND-004.
I did try to work Heinrich DL2XL/P at DM/NW-226, gut signal hr, but there was simply to many QRO chasers.

Summary: 39QSO, 2x DX to VK3 land, 1S2S SOTA, 1 GMA /P
DXCC: SP, OM, VK, G, HA, YO, I, OE, SM, OK, DL, OG, F, EA2, LA, DK, HB9, PA, ON

10m pole & 28' 800ohm /p ladder line

 Station:
MTR v2 - 20,30m - 5Watts
HB1B - 40m - 4Watts
Elecraft T1 & betterqrp baluns 1:1, 4:1
44ft doublet - inv V, 28ft -800ohm ladder line 
10m pole
44' doublet with wire-winders - 288gr
Many thanks to all the chasers.

Progress on VK5JST aerial analyser

I have so far soldered all the pcb components with except the central freq selector and 160pF variable cap.

Next is to prep the 14 short flex wire for the display
