Digital DX News from VK 20 April 2003
Welcome to Ron VK4XPA who copied VK3AXH and Ian VK1BG who achieved some
partial copy both ways with VK7MO in Hobart. Gerry VK2APG and John VK4FNQ
worked each other on six meters. Other stations on this weekend were VK1WJ,
VK2FZ, VK2AWD, VK2AKR, VK3HY, & VK3FGY. The numbers of meteors are still at
a low level but should build up over the next few weeks with the Eta
Aquarids that peak around 3 May.
Next weekend will be Type A on both Saturday and Sunday.
Tests continue each weekday morning between VK3 and VK7MO on 144.225. Skeds
and typical signal levels last week are as follows:
VK3AXH 0700 to 0715 local -15 to -24 dB
VK3ANP 0730 to 0745 meteors only
VK3CY 0745 to 0800 -18 to -26 dB
VK3AFW 0800 to 0815 -12 to -20 dB
VK3BWT 8815 to 0830 -15 to -20 dB
VK3AUU -18 to -24 dB
If you would like to join in, tail gate on one of the sked times after you
see 73s being exchanged or let me know and I will arrange a sked time.
Guy VK2KU reports on JT44 and CW EME contacts as follows;
OK1VVP CW #57
ZS6ALE CW (second try - easy qso) #58, new country
PA3CMC CW (second try, 1-yagi station) #59
DK3BU JT44 #60
GW4DGU JT44 (1-yagi station) #61, new country
CT1DMK JT44 #62, new country
Not a big haul, but some very pleasing contacts in there.
Unsuccessful scheds: JH2COZ (CW, twice), 9H1PA (JT44), EA3AXV (JT44)
RARE GRID SQUARE, QF98, LORD HOWE ISLAND
VK7MO and VK7TS will be operating from QF98, Lord Howe Island (VK9), from 3
to 10 May on 2 meters and 70 cms & 23 cm. Lord Howe Island is within meteor
scatter range of NSW/VIC/TAS/Southern QLD, NZ & FK8 and SA as far as
Adelaide is also a possibility.
The NSW East Coast (Pt Macquarie, 584 kms, Sydney 780 kms) should be just
possible on troposcatter on JT44 although a little lift may be necessary
particularly on 70 cms. Aircraft enhancement may allow 70 cms and 23 cm
operations to the East Coast of NSW.
Equipment will be an IC-910 H running 75 watts on 2 meters and 70 cms and 10
watts on 23 cms to yagis of 10 elements on 2 meters, 17 elements on 70 cms
and 25/45 elements on 23 cm.
VK7MO will TX in the first segment for all contacts independent of direction
and also when working ZL & FK8. The frequencies will be 144.330, 432.330
and 1296.330 which will be used for all modes including FSK441, JT44,
VFSKCW, CW and SSB. While this is not strictly in accordance with the band
plan it has the advantage that stations wishing to make contact can monitor
a single frequency. Operations will generally be on 2 meters with skeds or
QSY to 70 cm and 23 cm.
The general plan will be to operate FSK441 on 144.330 from 0600 EAST time to
around 0800 EAST (2000 to 2200 UTC) each morning from 4 to 10 May inclusive.
Once FSK441 operations conclude I will move to JT44. JT44/SSB can be run on
sked at other times during the day or evening. The first morning of
operations will be Sunday 4 May and activity will conclude around 10 am EAST
on Saturday 10 May. I will be in contact with Ian VK3AXH who will provide
more detailed information on the VK-VHF reflector. My colleague on the trip
Trevor VK7TS will be operating on 20 meters SSB and CW and you might get
messages through him. It appears that the mobile telephone system does not
extend to Lord Howe Island but you may be able to contact us through the
place we are staying "Ebb Tide" on 02 65632023 during office hours.
Current plans for FSK441 are:
Sunday 4 May 0600 (2000 UTC) start beaming Brisbane and move South as
stations worked to VK3.
Monday 5 May 0600 (2000 UTC) start beaming VK7 and move North to NSW.
Tuesday 6 May 0600 (2000 UTC) beaming ZL
Wednesday 7 May to be determined - possible reserve day for ZL, skeds for
specific stations not yet worked
Thursday 8 May 0600 (2000 UTC) beaming FK8
Friday 9 May 0600 (2000 UTC) to be determined - possible reserve day for
FK8, skeds for specific stations not yet worked.
Saturday 10 May 0600 (2000 UTC) FSK441 towards VK to pick-up stations not

(see next section below). For JT44 use the minus dB reporting format (eg
1919 means -19 dB) see example below and codes as follows:
