WSPR and QRSS frequencies

NOTES

These are not dial frequencies but the actual transmit range.  This list is for direct frequency entry transmitters such as the Hans Summers QRP Labs “Ultimate 2 / Ultimate 3(S)” kits.

Both 40m and 30m can be very overcrowded.  Please check the active grabbers before you transmit to find a clear spot and because it's so busy, please think very carefully before you run slow Hell on either band.
