SMALLWONDER LABS SWL 40+ MODIFICATIONS FOR 15M.

With a number of modifications, the stock SWL 40+ board and parts can be adapted for use on 15M. A distinct advantage of the SWL 40+ board is that the designer has made the board to allow for several user add ons like Audio filter, Audio amplifier, CW Keyer, RIT, and Frequency Readout with user flexibility, turning a simple practical design into an affordable QRP DX piece of equipment.

The following parts need to be replaced to make the stock Smallwonder Labs SWL 40+ board work in the 15M CW band.
