The WSE RXHFA is a converter that converts two radio frequency signals from the lower HF bands 1.8
to 14 MHz to 70 MHz.
The WSE RXHFA is designed for use together with the WSE RX70, the WSE RX10700 and the WSE RX2500 to form a high performance two channel receiver for shortwave. The output bandwidth is 2 times 93 kHz. The output is intended to be digitized by a high performance soundcard sampling four channels at 96 kHz. The WSE RXHFA contains five crystals and allows the 93 kHz wide frequency band seen by the computer to be centered in 25 kHz steps anywhere between -25 to + 450 kHz with respect to the band edges of the five HF bands at 1.8, 3.5, 7.0, 10.0 and 14.0 MHz. The RXHFA provides very high dynamic range and is designed to be connected directly to two separate antennas. Preamplifiers and attenuators are included in the box and allow the gain to be set from -15 to +10 dB in 5 dB steps. The WSE RXHFA was sold in the years 2002 to 2010 in a quantity of about 50 units for a price of 2800 SEK excluding VAT. The WSE project is now closed but there is some left-over from the project that we offer here: WSE surplus The WSE RXHFA is designed by SM5BSZ, Leif.
