Paul, With the various QRPme kits that I have, I use M RCA to F BNC adapters. Or, if mounted in an enclosure with BNC panel jacks, I use a twisted pair of wires from the board to the jacks. The twiste

4SQRP Nets and QSP

Is it 40M or is it me?

Is there a net on 7122?
40 meter propagation lately is rather iffy. The 7047 early morning net survives with a lot of QSP between the members and NCS. From me, EM22cv, most of the net stations range from Nova Scotia to South

Favorite key
The only "straight key" I've ever had and used is also a WW2 J-38 bought 1955. I used it a lot and even wore a groove in the knob. Not used now and only use the unmentionables... Chuck Carpenter, W5US
