[Antennas] Problems with my DENTRON WM-2 WATTMETER

[JAB (EA5XQ)]

Hi to all,

I bought recently a second hand (via eBay) DENTRON WM-2 WATTMETER and now=20
I'm facing several troubles that I do not know how to fix for the time=
 being.

It seems that, and was identified in 17m, that the meter introduces a lot=20
of noise in the band and also changed completely the SWR graph of the=20
antenna. The noise I discovered that was produced by a near computer -with=
=20
my CN101 meter it did not happen- and moreover the meter was RADIATING as=20
it was affecting a lot (in 17m and 15m) the computer, a clock close to the=
=20
meter and other devices (it did not happen neither with the other meter=
 CN101).

Anyone could provide me a schematic of the meter and ideas about how to=20
avoid such radiation?

Thanks
