[Premium-Rx] Noise Power Ratio Testing of Radio Receivers: preselectors

[Борис Никитин]

Hello Good People,...

Thanks for that interested discussion, but I'm remember "Old Timer's' receiver (AR88) for example when you can make many
DX QSO's with that simple, classic radio...Now very sophisticated receivers are available, but nothing to search across
the SW Bands...Uncomparable with days before GPS, Internet, Satcom's. When just SW Radio only was available...

SW-Bands will never ever interested like before...Some 50-60 Years ago with good Receiver or without...My own profession already dead oficially from Febr. 1998...No any Radio Officer's any more...That is why I'm almost left SW-Bands  some 6-7 years ago and shifted to Microwave Band 8.4GHz ..."Green people" not found yet, but much, much more and really interested...

Best Regards for all.
