[600MRG] RF Ammeter

[Scott Armstrong]

 Hi Guys,


A couple of questions....


Wondering if anyone has any information on this meter.

I have a Simpson Model 135 RF Ammeter.  Full scale is 2.5A
Does this meter have a thermocouple built in or did it use an external
thermocouple?



Can anyone point me to a schematic for a RF Ammeter that will work at 2200m
and 630m and has a top end of say 1-1.5 A.

The Simpson meter, if it does have a TC built in, will not work very well
for low power ~25Wapplication. The meter scale being non-linear  does not
have much resolution on the bottom end of the scale around the .7A range.

Thanks,
Scott AA5AM
