Here's my cool toy.
I have always wanted a new scope. I just bought one of these thinking the price of everything is going to go nuts. It's amazing how much you get now for the money.

It has a voltmeter and frequency counter in it. I sure all new scopes do. But the SDR radio I have does a much better job of showing a mixer oscillator frequency with all it's unwanted products.
Here's a SDR radio short video showing the entire AM Broadcast band with all the station carriers.

Here's another vid showing the local oscillator moving while tuning. It appears and moves at the right side of his monitor screen at 2:06 minutes in.
Just by connecting a small loop coil to the antenna port and parking next to a osc mixer it will reveal all.
