Just a couple of minutes to take it all apart, so easy for trying things out on.

Battling a bit with the BFO calibration, bot much on the air to set it on. Try again later.
Main frequency is spot on.

But just worked EA7 and 9A on 2W :)

I got it on ebay about 4 years ago, bought 3 at the time. The seller ID had a mrs in it, that is all I can remember.

It is plastic.

The final one will be in a metal case.

I've just received one of these https://www.ebay.co.uk/itm/9-8-x-7-5-x- ... 2749.l2649 I ordered a couple of weeks ago.

Very nice for the price.

I don't like the white and blue, but a couple of tins of spray paint will change that :)

I went into the loft this afternoon to look through the boxes of Yaesu spares to get some panel lamps for the FL 7000, and saw I had some meter assemblies for the 757, still in their packets.

Brought one down and connected to the bridge, and it is perfect, gives full scale with 10W, so room for calibration.
(picture hows it adjusted)

With the aid of a hacksaw, it will make a nice meter for the μBITX
