Do you find that you need a pre-selector where you are at due to high signal

I've never found a reason here to use an 'outboard' pre-selector.


For sure I don't need this on the NRD-525 as you dont need one on the
Drake-R8B... :-)
But as I had the things available I gave it a try on the NRD too :-)
On the Sony the external antenna with the FRA/FRT combo works wonders.
You can use them together to passbandtune for much more seletivity than
the Yaesu FRT-7700 preselector alone is giving. For sure you have to
fiddle on the knobs a lot. This may be another thing with other brands.

Well, years ago, when I got back into the shortwave hobby (circa 1982 or so) I did
eventually purchase a FRT-7700 for use with the FRG-7700 which I had at the time.
