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

Von: John RABSON <[email protected]> An: [email protected] Verschickt: Di., 11. Jan. 2011, 12:16 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? 73 John F5VLF |
