Hi again Kev,
Sorry for the delay getting back to you - I got sidetracked. Re your last post(s)...
‘star’ ‘shaker washer’ - it depends what you are fitting it to. They are designed to stop the socket shaft turning as you tighten the nut and potentially twisting the cable, so on a flat panel it could go inside or outside. With the Stratux/Rosetta cases there are - as you say - plastic hex mouldings on the inside to hold the socket in place, so you can either fit the shaker on the outside, then the plain washer/nut or simply discard the shaker. I have in the past used a shaker (or plain washer(s)) as a ‘packer’ between the Bridge and case to prevent overtightening of the nut twisting the Bridge and putting a strain on the GPIO pins. That’s what I was referring to above, but that’s probably overkill on my part.
Yes, you can remove the case on the SDR - always worthwhile to maximise cooling when it’s inside an outer case, - just be careful not to short anything out if poking about inside later with anything metal.
If you look closely at the photos in the thread you have linked to, you will see (from the end-on pic) that Mike has actually fitted his 1090 antenna to a hole above his ‘Classic’ Bridge. The ‘Rosetta’ Bridge was actually redesigned with a cutout to allow the 1090 antenna socket to be fitted ‘in line’ with the Bridge (I’ll post a pic later for you) - but these are not available to purchase separately.
Hope this helps clarify these issues.
Best Regards
Peter
