Wagging DX-35 Meter

[Rinkie & Ron Pollack]

I use a DX35 and DX20 fairly regularly, and an AT1 occasionally.  All do the
same thing.  To avoid too much key down out of resonance, I initially tune
into a dummy load through an swr bridge, and tune quickly for max output,
which is going to be real near resonance.  Just the nature of the beast!

Subject: [HEATH-TEMPE] Wagging DX-35 Meter


Hello All...

I'm looking for either a replacement meter for my DX-35, or expertise on
how to remedy the needle wagging like a happy puppydog's tail.

For example, when loading the final, dipping the plate from the pegged
position causes the meter needle to wildly bounce back and forth and
doesn't settle down fast enough to get a reading.  Getting a grid current
reading is impossible.

It does appear to be a problem with the meter rather than the transmitter
as it does this "wagging thing" out of the circuit with a low voltage
applied via taking a resistance measurement with my VOM.

The original DX-35 meter is a black metal bodied Shurite style (see any
50's era ARRL handbook advertising pages), 0-3 ma, 500 ohms, with 0-150 on
the top scale and 0-6 on the bottom.  It may be stamped with 484621,
although the part number in the manual is 407-33.

Thanks & 73,
Tony
