[Elecraft] New Firmware (k3fw5r57) Causes Odd Sound

[ke9uw]

Could be. I don't have the new synthesizers but the noise is there they say. And just cannot be heard because of the higher phase noise. Maybe my phase noise is low or my fan electrical noise is high.

Thanks for the tip.

Is it possible you need the KPAIO3MDKT?  This cures some issues with electrical fan noise getting into the transmit signal under some conditions after the KSYN3A is installed in all K3 radios and K3S radios before serial (about) 10730.
