I love how you took the time to explain what you were doing.

Finally a test over weak signals. Thanks.

[@EricFullwood]

CW is always extra special on an Elecraft

[@JayN4GO]

Amazing rig. Price is through the roof as usual but it’s great at CW

[@kd5dcj]

WOW, nice rig, afraid to ask what the cost is lol.

[@oe5pop320]

Great TXm Thx for Video

[@johnratcliffe6438]

Some SSB receive showing DNR effectiveness please.

Does that K4 have two receivers? Do I need dual receivers to work a pile up with two separate filter cuts on the screen? I never use two receivers so would rather not pay for it.
