For best results, this should be implemented on the same PCB with the LNA.
Also, a bipolar Vcc in SoftRock would be a big plus, this might improve the
dynamic range by 10 dB. The saturation point of Delta-44 is 14 dBu (about 11
Vpp), but the LNA powered with 5V can produce only about 3 Vpp.
What about a bipolar power supply kit for SoftRock?
