Glad to hear it.

I tend to use an Android tablet when out portable, and find that most useful as it saves the added clutter of a laptop, tethering to a data source etc.   I'll PM you regarding the other two though, as I do like to get to the bottom of these things!

Re: 3D printed cassegrain reflector.

Without the copper, that could make a good mould for casting in aluminium. Simply gluing on Aluminium foil and pressing it flat might be OK at LF (e.g. 24 GHz) but might not be good enough at 122 GHz. The other thing you could do with this, if it is round, is use it with a lathe as a template to copy with one of those copying attachments. Not sure how accurate that are, you probably need better than 10 thou.

Re: Buying from the EU

Robin Szemeti - G1YFG
 

I think £50 is a reasonable value to put on a piece of broken electronics that probably only costs double that to manufacture in the first place.

I've not insured an outbound parcel in 20 years ... UPS just don't lose things, and if they do, I just take it on the chin and ship another. I can only think of a couple of items lost in recent years .. and both of those in the UK.

"We always advise customers to avoid mentioning anything to do with repair and simply put a value of £50 on it. It's cheaper to pay the (small) amount of VAT and a simple handling fee than the  handling fees on the "repair" customs procedure which are usually around £70."
This is actually illegal and could be considered fraud. Apart from that, if an item goes astray or is damaged the insurance company is unlikely to pay more than the declared customs value. I assume this is EMC test equipment that costs a lot more than £50.
