> Hi Folks,
> 
> I've recently purchased a Johnson Kilowatt Matchbox into which someone 
> has installed the meter and line section from (it looks like) an old 
> Heathkit AM-2 SWR meter. As most everyone knows, these meters measure 
> relative power and relative SWR, subject to line section design, 
> component tolerances, etc., rather than true forward/reflected power.
> 
> I would like to replace this meter and line section with a cross-needle 
> type meter and true wattmeter line section like Daiwa and MFJ use in 
> their wattmeters. I have done some serious searching online, but I 
> haven't found any cross-needle wattmeters which appear to be good 
> candidates for cannibalizing the cross-needle meter and wattmeter unit. 
> The meter movements in the Daiwa and MFJ wattmeters all appear to be 
> integrated into the case of the unit. I need to find a cross-needle 
> meter I can remove from the wattmeter housing and install on the front 
> panel of the Johnson Matchbox, and then install the line section in a 
> shield box inside the Matchbox cabinet. The Daiwa 620 and 720 meters 
> appear to be the best choices based upon the way the meter movement 
> appears to be attached to the wattmeter housing, although I haven't 
> looked inside the housing to see what would be involved in removing the 
> wattmeter/line section unit and installing it into a shield box.
> 
> Can anyone out there give me some tips as to which cross-needle 
> wattmeter I should be looking for as a source for my scrounging 
> activities? If you have a wattmeter which looks like it would be 
> relatively easy to remove the meter and the wattmeter section and 
> transplant it into a Matchbox housing, let me know the make and model 
> and I'll start watching for one to show up.
> 
> I suppose I could just remove the meter and line section from a cheap 
> Heathkit wattmeter and install it in the Matchbox, but I love the 
> cross-needle meter in my MFJ Differential-T transmatch and I'm spoiled.

> Thanks!
