One of the best I ever found for SWL was the Global AT-2000, sadly no longer made, but you may be able to find one used
it works extremely well, or now the MFJ1046 is similar...

By the way, "DM4070 LCR meter" could be an honest tool for the price?
(about 40-50 $ on e-bay)

I use this one and find it excellent. Takes very little building.

With HDSDR or SDR-CONSOLE 2.x, the SDR-PLAY is now my favourite HF general coverage Rx. (One of the alternatives is an AR7030).

Thank you very much to all. I get a lot of ideas from this forum.
I'll try to build a preselector by myself.

By the way. Yesterday I was looking for info about "usb galvanic isolator" and suddenly I found a cheaper solution.
I moved SDRplay from one usb port to the near one, a lot of "vertical lines" disappeared. Great!

My gathering dust Yaesu FRG-7, might be put back into service as MF-HF RF pre selector, new life for a old boat anchor :)
