New 434 MHz to 2.4 GHz Transmit Converter

The new OSCAR 100 satellite in geostationary orbit has a downlink in the 10 GHz band and an uplink at 2.4 GHz.

I was looking through the most recent edition of the Dutch Kingdom Amateur Radio Society  magazine and I noticed this transmit upconverter...


The price seems pretty modest for what it does although I don't know anything about its performance.

From what I understand, something like 2 watts into a 2.5-3 metre dish or 10-20 watts for a 1-1.5 metre dish is required for an SSB signal for the uplink at 2.4 GHz.

Listening to OSCAR 100


The new Geostationary satellite OSCAR 100 is now up and running and the narrow band down-link can be heard online here... https://eshail.batc.org.uk/nb/

The up-link is at 2.4 GHz and the down-link is at 10 GHz.

Anytime I've listened during the last week, there has been a small number of signals on the down-link. There has been a lot of hype about this particular project although I'd wonder about how popular will it be?

The coverage footprint is shown below...
