Receiver

Last updated 2005-1-23


The APT receiver I constructed had been designed by Gerald Düllberg DL8DAQ and had been published in UKW-Berichte, Vol 1., 1997, pp 17-30.
For autoscanning a microprocessor controlled PLL had been used which also included an AFC for doppler tracking of satellite transmissions. Kits had been available at those times.

The design of this receiver is very similar to the RIGSAT RX-2 and to the RX137 receiver from emgola, just to mention some alternatives still available.
