I recently saw this happen on W6NV's P3 after upgrading the firmware from a very old version to the most recent version in one jump, or perhaps I accidentally removed power from the back of the P3 while it was on, while simultaneously bumping one of the front panel buttons. Reloading the firmware and doing multiple power cycles did not fix it.
Instead, if you can get to the P3 menu, go to the RESET option and press the knob. Or, if the P3 Utility still talks to the P3, go to the command tester and type: #RST; You may then find that the REF LEVEL is set way too high at 0 dB. Adjust REF LEVEL back down to about -120 dB and it should be back to normal. 73, Bob, N6TV On Tue, Apr 10, 2018 at 7:14 PM, Fred Jensen <k6...@foothill.net> wrote: > My P3 waterfall disappeared when I turned the rig on tonight.
