DX on Oscar 100

Just heard PY2GN in Sao Paulo calling CQ. It seems odd to hear South Americans as easily as Europeans. Of course, as long as these stations can see the geosynchronous satellite and run similar gear there is no reason at all why they should not be equally strong.

UPDATE 1206z: Just heard F0JBN JN08 running 100mW.

UPDATE 1547z: Excuse my ignorance, but on the Oscar100 webSDR there are coloured lines above the frequency marks. What are these?

East Cambs net Mondays 144.575 FM vertical 8pm

A reminder that a few of us usually meet at 2000z on 144.575MHz FM on Monday evenings. Discussions rarely go on after 2030z. Newcomers are always welcome, even if you cannot stop long. This is one four four point five seven five in the all modes section of the band. Operation is usually stations in the East Cambs area. We use vertical polarisation. Discussions are wide ranging covering technical and non-technical things and the technical stuff is never heavy - usually a participant asking advice. If we can comment usefully, we do!

Sunspots - Monday February 18th 2019

Solar flux is 70 still and the SSN still 0. A=4 and K=3.

2m FT8 RX

I remained on 2m FT8 overnight. This morning, 10 stations in 3 countries spotted so far with best DX spot being DL6BF (479km).

UPDATE 1348z: Now 19 stations in 7 countries so far spotted today on 2m FT8 RX.

SSTV from Oscar 100

Although I made no attempt to decode it, someone was sending SSTV through this geosynchronous satellite earlier.

Also, DD0CW was a good signal on CW, which is the first time I have heard any CW via this satellite. I am sure others have used this mode, but not when I was looking.

Again, using the webSDR to check activity. At the moment about 4-6 QSOs ongoing at any one time, so not busy. As yet, my best DX heard via Oscar 100 is an A71 in Qatar. I know others have heard PY. It must be odd to receive DX stations with no QSB and at any time!

UPDATE 2247z: GU6EFB has been calling CQ for ages with no takers. I guess most USB operators have tried and worked those that are active. As far as I am concerned, the vast majority are Europeans and mainly Germans and English stations. I guess there are fewer microwave enthusiasts in Africa and South America. I expect some will start with just the 2.4GHz TX and receive using the webSDR?

Gardening - NOT amateur radio

As the weather was sunny and mild, we decided to do some gardening.

I trimmed back some choisya, which smells like lemon. After about 20 minutes I was totally exhausted and had to stop. When on my feet I am giddy all of the time, but stretching as well just did it for me. I am pretty sure this is my 2013 stroke after-effects and not just me getting older.

It was nice to be in the garden, but I have to learn to pace myself.

New friend? - NOT amateur radio


As the weather was so good today, we went to Hare Park at Chippenham, near Cambridge to see the snowdrops. There were a few daffodils out, but not many.

The second photo is my wife with one of the statues.

The photo at the top shows some of the snowdrops.

Spring? - NOT amateur radio

Yes, I know it is only February and we could still get really cold weather and snow. However, it feels like spring and the daffodils on our green are in full bloom. This picture is a few days old and they are even more in bloom today.

2m FT8 RX

Much of the morning, I have been on 2m FT8 RX. So far, 29 stations spotted here with best DX DF7JC (468km). Once again using the FT817ND with the big-wheel omni antenna.
UPDATE 1621z: Currently 50 stations in 6 countries spotted today on 2m FT8 RX.

UPDATE 1754z:  Now 56 stations in 7 countries spotted on 2m FT8 RX today.

UPDATE 2230z:  Now 71 different stations in 8 countries with best DX spotted DL3TW (655km) on 2m FT8 in the last 12 hours.

Overnight on 472kHz WSPR

Last night (overnight) and last evening, I was active on 472kHz WSPR with 10mW ERP from the earth-electrode "antenna" in the ground. I would describe conditions and results as "average"  with 7 stations spotting me and I spotted 9 stations. On TX my best DX was a spot by F59706/1 (560km) who copied my 10mW ERP at -23dB S/N.
