Title: Analog meter static Post by: wa2tak on March 13, 2023, 11:01:12 AM Just had this problem.
Thought I'd pass along the fix. The analog meter needle sometimes get 'stuck'..and does not go to zero. Static charge on the meter plastic face causes this. Solution: wipe the plastic face with that anti-static fabric used for clothes drying. Title: Re: Analog meter static Post by: wa2tak on March 13, 2023, 05:50:03 PM Correction
I meant to say...NOT ZERO...but the 'set' position on the meter.

Rub your hand on your shirt and then across the meter face and watch for needle movement. Panel meters on old rigs are sometimes seized up - sometimes fixable, sometimes not.

Static charge on the meter plastic face causes this. I experience this once in a while. I use a tape head demagnetizer. Takes care of the problem. Have yet to notice any deleterious effects from doing this. Doug Title: Re: Analog meter static Post by: W1RKW on March 16, 2023, 12:16:48 PM I lick it.
no, not really but a dampened cloth works too. Title: Re: Analog meter static Post by: K2GTM on April 10, 2023, 06:54:22 PM I have good luck with blowing a "hot breath" on the meter face. Those who wear glasses know about doing this to wet the lenses for cleaning. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
