I agree that good antennas and having QSK are important but I'm not sure
that improving your receiver will help you get more QSOs. I know
conventional wisdom says "you can't work 'em if you can't hear 'em", but
not hearing stations is rarely the problem. I've used all kinds of simple
receivers, direct conversions, simple superhets, etc. and don't think I
ever lost a QSO because of my receiver. The problem is that if you're QRP
with a no-gain antenna you hear TOO MUCH. You hear a DX station at say, S5
with a pileup on him and you waste hours calling him when there's just
about no chance that you'll work him; even if there weren't a zillion other
stations calling. I say that the best receiver accessory for a QRPer is a
10 dB attenuator pad on your receiver input. That way you're more likely
to concentate on stations there's a reasonable chance of actually working.
