Hi Parrish:
The antenna is just as important as the radio.
For receive applications the T2FD is hard to beat (and also for many transmit
applications).

I claim that using a chirp receiver is the best way to evaluate a receive
antenna.
A key radio specification is the IF bandwidth, the narrower the better for
detecting a signal.
Of course the IF needs to be as wide as the signal to hear the modulation.
For example the HP 4395A spectrum analyzer has a true 1Hz RBW, it's my most
sensitive instrument.

The NRD545 has a 10 Hz IF BW, which is the narrowest receiver I have.

Have Fun,

Wouldn't be any point. A shortwave receiver covers more freqs (unless things
have changed) and should receive just as well as a ham receiver. Unless you
just want to listen to hams. Just my view.
I’m mostly just mulling things over. I’m new to shortwave and don’t take it
very seriously, but I’m finding myself kind of annoyed at my astoundingly bad
fortune in picking up number stations with my Grundig G5 with a whip antenna.
I’d like to figure out whether it’s because I need a better antenna, or a
better radio, or because I’m overlooking something else, or simply because I’m
doing something wrong. I’d say it’s most likely the last one, but even so, I
want to look at the other possibilities as well.
