1N34A's in OHR WM-1?

Experience with the RF detector in the Elecraft K2 seems to have
established that some 1N34A germanium diodes don't do such a great job
on 10 m. One solution to the problem is to use a small signal Schottky
diode like the 1N5711 instead.

The OHR WM-1 (and probably the WM-2) have 2 1N34A detector diodes and a
third one for compensation.

Has anybody verified its linearity vs. frequency?

Would it be advisable to replace the 1N34A's in the WM-1 with small
signal Schottky diodes?
