Digital DX News from VK 9 March 2003
- FSK441 2 METRES
Welcome to Rod, VK4KZR, who joined the group this weekend. Stations on this
weekend were VK2FZ, VK2AWD, VK2AKR, VK3AXH, VK3KAI, VK4KZR, VK4TZL and VK7MO. VK2LRR, VK7KRW, VK7IR, VK7KRJ have been listening in and copying
segments of FSK441.
Next weekend will be Type A on Saturday and Type B on Sunday to give the
VK2s the opportunity of beaming North to VK4KZR.
Tests continue each weekday morning (0700 to 0715 and 0745 to 0815 local) on
144.225 between VK7 and VK3. Stations involved include VK3AXH, VK3CY,
VK3HY, VK3HZ, VK2LRR, VK3AUU and VK7MO. Anyone else who would like to be
included in a sked at a specific time please let me know.
JT44 TERRESTRIAL REPORTING
A number of stations have been experimenting with a different way of
reporting on terrestrial JT44. The standard method included in the program
is based on exchanging both call signs and grid locators which are the
unknown information. In practice grid locators are usually known so we have
been experimenting with exchanging signal reports in -dB. Thus if the
strongest signal seen to the time of sending a report is say -18 dB one
would send 1818. We are also using PPPP to indicate the partial reception
of a signal as well as RRRR to indicate full reception of both call signs
and reports. Thus the form of a QSO is as follows:
VK3AXH VK7MO QE37 VK7MO TXing
VK7MO VK3AXH 1818 PPPP VK3AXH TXing
VK3AXH VK7MO 2222 RRRR VK7MO TXing
RRRRRRRRRRRRRRRRRRRR VK3AXH TXing
737373737373737373737373 VK7MO TXing
1. Only send RRRR or RRRRRRRRRRRRRRRR when you have received both call
signs and a report.
2. Once you start sending a report stick to this same report even if the
I would welcome comments on this reporting system.
Mike VK2FLR reports on EME contacts as follows:
Nothing in the past week as moon conditions have not been suitable, but
further back I have:
16 Feb 1835 S52LM Sync 7, -18dB (big gun)
1840 HB9Q Sync 10 -11dB (big gun)
1845 SP2OFW 8/-15 (four yagis)
1902 OH7PI 4/-21 (four yagis)
1909 GI6ATN 4/-22 (two yagis)
17 Feb 1806 IK0BZY 5/-19 (one yagi, X pol)
1853 PA3CSG 4/-23 (not sure)
1903 G4YTL calling CQ 3/-22 (four yagis)
18 Feb 1935 DK8ZJ 5/-18 (four yagis)
2057 S52LM 8/-17 (again)
2112 PA0JMV 6/-20 (two yagis)
19 Feb 2130 GI6ATN 4/-21 (four yagis) incomplete)
During one of these sessions I had a couple of decodes from a German
station running one single 12 element yagi and 100 watts.
The next good moon period is from about March 15 to March 25.
Single yagi stations with JT44 on board should look for signals at moonrise
and moonset, using the JT44 EME logger at
VK3AXH, VK3KAI and VK2FLR have been experimenting with the new digital mode
JT6M on two meters to look at its ability to handle aircraft enhancement -
to date these tests have not produced results. VK3AXH, VK2AWD, VK2AKR and
VK7MO have done some tests on 6 meters - while it is early days the mode
seems to have lots of potential and it certainly sounds nice to listen to.
