TS850modifications
From Wiki_pegasus
VCTXCO upgraded, for higher PLL-reference stability. This small PCB can work in many synthesized Kenwoods
Kenwood TS-850 Noise Blanker Modification - stiffens the bias-voltage, raises the threshold
TS-850 volatile-memory backup battery relocation (mine's under the DRU-2 top-cover hatch, for easy replacement)
Make the CW sidetone level adjustable, via the front-panel MONI control (just like SSB)
Stablize the Transmit-ALC reference-voltage, by broadening the operating range of the multivibrator/invertor
TS-850 Low Band (MF: 0.5MHz to 1.6MHz) Sensitivity Improvement
