USA digital geostationary satellite?

Excuse my ignorance, but I am confused by the difference between a geosynchronous and geostationary satellite. 

Apparently there are moves afoot to get a high orbit satellite with a footprint over the USA. Oscar 100 does not cover the USA. This one should be digital.  If so, I expect it will get even less attention that Oscar 100, which is seriously under-used.

In my view, these satellites are interesting to access at first, but interest soon wanes later: people know they can access them and then they get bored. It is just like talking on a terrestrial repeater.

Cold Devon day - NOT amateur radio


This was the beach in Devon near Thurlestone Rock. It is near here that I come from.

2m activity contest results

The results have just been published for the 2m UKAC contest. These results are for December and the overall scores for the year. Despite just one QSO in December, I managed to end up in 67th place in the low power section (I run 10W to my big-wheel omni antenna) out of 175 stations.  As my voice is poor these days, I find SSB contests hard work, so I usually stop on for 30-60 minutes only.

SDR has arrived


It is unlikely to be tested for several days, but my SDR has arrived. It is meant to cover from 100kHz to 1.75GHz.

Looking for software recommendations to use with it please?

Amaryllis at last - NOT amateur radio

We love watching these amazing plants grow in pots during the winter. A bulb grows into an enormous plant with huge flowers. We thought this one was a dud that was never going to grow. In the last few days it has started. Usually they take about 4-7 weeks to fully mature. Each morning they seem to have grown!

Intermittent 10m antenna

This morning, I was planning to go on 10m QRP FT8, but something is still intermittent so I have a high SWR. I suspect the coax plug. At some point, I shall have to remake the joint. These days, this is less easy as my fine motor skills are poor.

8m QRP FT8 (Saturday)

 At the moment (1106z) I am on 40.680 MHz FT8 with my 2.5W and low wire dipole. No spots on RX or TX.

UPDATE 1545z:   No spots.

Oscar 100 activity (or rather lack of)


Every few weeks I take peek at activity on the narrowband transponder of this geosynchronous satellite. My latest peak was at 1045z on Christmas Eve. This is European Saturday morning in a holiday, so I would have expected activity to be as good as at any time. What did I find? Very quiet (see screenshot).
