The most convenient way to feed 12 VDC Your 137 MHz receiver should have an IF bandwidth of 40 kHz to receive decent pictures, Too narrow an IF bandwidth will not allow the full FM deviation frequency swing from the spacecraft to be accommodated in the passband, resulting in useless pictures,...

There are a couple of downsides to the Azden. One The documentation is a bit lacking. The PCS-7200 does not have its own instruction manual, but uses the PCS-7000 2 meter rig manual, with an Addendum sheet to clarify the differences. The PCS-70G0 manual has typographical errors and other mistakes, and using it with an Addendum sheet means referring back and forth between two papers to get things right. Secondly, the Azden is not particularly user friendly ' and requires real...
