I believe that operation is possible down to 300 kHz. or so but have yet to find the recipe. All of the appropriate diodes have been removed with the exception of D48. The machine performs well anywhere between 1.6 and 30 MHz. Any advice would be appreciated. On the other hand, my IC706 Mk2 can deliver a few watts at 500 kHz and a useful watt or two at 136 kHz. Stability is more than adequate for QRSS3. In passing, I have been following Stefan's efforts from the other side of the earth. His dedication to the VLF cause must be an inspiration to all. 73, Kevin ZL4MD
