Has anybody used this unit ?    It's unique in that it does not require a
separate noise sense ant.
It's  made by   SV3ORA.

It can also be installed in the RX only loop, commonly used in most
xcvr's.  Then it can be used safely, and also used with  QSK.

It has a separate bandswitch...'marked  'IMD'.  The unit covers  1.6  to
over 70- mhz......and everything in between. It can also be modified for
use on  the 2 x lower freq bands.
