LED diagnosis, large circuit boards, wide traces/pads, and step-by-step instructions make this the easiest double conversion receiver you will ever put together. For more information read Amateur Radio ReceiverAn CW/SSB receiver that covers the first 100-150 kHz of the 40 and 20 meter bands and all of the 30 and 17 meter bands. Bandwidths can be modified. SWL ListenersThe tuning range of the VFO is expanded to 500kHz to cover most of the 41/31/19/16 Meter SWL bands. Duncan Watson and Gary Rondeau have sent in modifications they made for improved performance of their receivers. They include VFO, crystal filter, AM Detection, and AGC modifications and improvements - check them out. |
