Well, if this turns out to be all they're promising in the pitch here, it would be quite suitable for Part 15 AM use.

At least as long as you are at 1600 or up. Only needs 50mW to work, and it appears no direct connection to the output, as it mentions using "sensors".

Lots to read here, and it's a pre-order, but I'm tempted just to check it out and I can alway suse it in ham applications as well.

Like so many Part 15 hobbyists I have dreamed about a serious useful RF meter for our benefit, and at last it has come into being!

Only last year I said to the devil, "If you get me a good RF meter you can take the soul".

It will be worth it!

I found this:

Antenna Connector: N-type

Impedance: 50Ω

Doesn't do what we really need.....an AFFORDABLE meter that will measure field strength down to 100uV/M at AM and FM band frequencies.

Now if they could come up with something like that.........say under $1000.

And hand held to be portable.

This is how the sensor connects to the unit.  The mod monitor I had that used the computer for interface/readout (dang I can't remember who made them) you had to purchase the proper box for band and power, that connected to an antenna loop -- basically a hunk of wire near the antenna -- which then connected to the unit. There was no direct connection.  I'm suspecting this Heathkit will oeprate the same way, based on the mention of different sensors being available. If power ran through it, sensors would not be needed.

We shall wait and see.

You can already do that with a used Nems Clarke or RCA WX-2 if you watch for 'em on ebay and the various used broadcast equipment sites.  Easily obtainable for under $1000. You can get calibration close enough with help from an engineer with a recently calibrated machine.  EVen if you just have to add/subtract any error.  They are actually amazingly stable.  But not as critical for AM, as if you're using the rule for AM field strength, you're not getting out very far. 

Never happen for FM.  Too complex to be accurate cheaply. A Potomac FIM-71 is the cheapest way you're going to do it -- there are several on eBay for around $2,000.
