Nice work Steve.
I seem to be the only person who couldn't get knobs to fit.

Is it succesfully dual band?

It is successfully dual band :)

I just used the knobs that came with it, but would point out that the encoder and volume control are mounted on the case and not on the PCB.

I also fitted a DC socket on the case.

The tactile switches are ones with long shafts, not the short ones that came in the box.

All working as it should, I want to calibrate the frequency to read the same as the 7300, it is about 200Hz out.

I wouldn't say it is better than the 7300, but it is not worse. Probably easier to listen to, the noise seems less compared to the signals.

Unbelievable performance for the money.

I had to mess around to set the frequency, but now it is now within 10Hz of the display on the 7300

I have built numerous QRP rigs in the past, but this makes them all look like toys.

It would be a very respectable rig to use at home if the power was all that was needed, very easy on the ears.

My only minor irritation is that the sidetone goes through the volume control, and as it has no ALC, you need to adjust the volume for the station you hear, which means the side tone level changes too.

It's like getting the 7300 all over again :)

The decoder does a better job than most too, didn't notice at first, but checked it and it is fairly good if you like them.

You...be done the same as me vis vis buttons and dc etc. I agree, the performance is unquestionable, the qsk flawless and reader is very good.

The downside I find is dodgy keying on iambic a and on mine an iffy start up...known fault. It needs work to be really very good as a kit but not for the price. At forty quid it's disposable. Thats the way to see it. But mine works like yours and I'm impressed. It'll be my portable rig in the summer.
