Discovery Dish on an IEXOS-100

[Pablo Lewin]

This is my Attempt to create a beginners fully steerable and trackable Hydrogen Line Radio Telescope for less than $600 US...to be used portable in good weather but eventually I will build a cheap PVC tubing/Tarp 6ftx6ft cover to have this working year round...so far, so good, the following is the video link to the first structural test..

I tried this - for me there was too much RFI, probably due to the iEXOS Wifi.  I also have a Celestron AVX mount - it works quite well - no detectable RFI for me.

That's why first I will shield the WIFI with the copper tape and if that doesn't work I will eliminate power to the WIFI board which is easy to do, either by cutting power to it or grounding the antenna...

I would be interested in knowing if that works.  Not sure I would want to fiddle with the wiring on the thing, but if wrapping it with foil works that would be good.
