John, the 1N4007 can actually be useful as a varicap replacement to pull an oscillator.

Thema: LF: RF ammeter question
LF,
I have built the fullwave rectified version of the design shown on page 10.33 of
the RSGB Handbook 10th edition. It reads correctly at 25kHz but only show 1/3
of the correct value at 136.
Not having any 1N4148 diodes I used 1N4007s. Might this be the cause of the
problem?
