Used with Winrad or the just released WRplus, it is an incredible LF receiver. The standard version only needs a 520 kHz low pass filter to get rid of the dreaded third harmonic LO mixing problem. I am having a ball with mine and with a decent 192 kHz soundcard a 192 kHz wide band can be sampled and saved overnight. My apologies for the wrongly sent email. 73, Roelof, pa0rdt
