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.
