Certificate surprise!

I got an email from my better half this morning asking me what deliveries I was expecting as the postman had left a note.  I couldn’t think what it could be and quickly forgot about it.

Much to my surprise, this it was is was…

Shadow-beacon experiment
What a lovely certificate for my (fairly minimal) participation in the experiment.  In fairness the photograph taken with my phone does not do it justice.

My received phonesat packets.

I was travelling with work most of last week, but set up my machine to see if it could receive AX.25 packets from and of the phonesat satellites (which have since de-orbited).

I was surprised to find these in my log when I got home

I was quite surprised to receive them as my set-up is not all that good on UHF.

Arissat-1

Arissat-1 is hopefully going to be deployed late afternoon Irish time tomorrow, August 3rd. That means switched on and given a bit of a push away from the International Space Station (ISS) during EVA-29.

I was listening for it during testing over the weekend, my time was limited, but unfortunately I didn’t manage to hear any audio from it on the 145.950 downlink, from the mailing lists, it seems some could some couldn’t. As it is much weaker than the ISS

If all goes according to plan, the first areas that should be able to receive it will be South America, very southern South Africa and then southeast Asia.

Steve Bible, N7HPR is blogging about how it was designed and built over the next few weeks on Electronic Engineering Times called “Chips in Space – The Building of an Amateur Satellite“.

I’m looking forward to trying out the linear transponder on it, it will be interesting to see if I can use it with an Omni-directional aerial.
