A  .pdf  of the RSGB “Low Frequency Experimenters Handbook”  good !

The Monitor Sensors 630m Transverter.  Very high-end, high quality rig… minimum 50W out, full linear, IF in 160m ham band, 13.6+ VDC.  Complete fail-safe circuitry included in this design.  I own one.

The receive converter in this rig has to be used to be believed!
