Cobra 2000 GTL ideas...

- Start date
Back in the bad old (good?) days when a straight 2 or four transistor "box" could be had for a modest sum the opportunity arose for some so obvious it isn't even clever additions.
The easiest was pick up a pair of Cobra 2000 external speakers, put a good supply in one of them and the amplifier in the other. Nothing fancy, just a 100-200 watt upgrade.
The second was digital synthesizers were beginning to appear and be somewhat reliable. A true Digital VFO was a possibility.
Fast forward to today and an SDR sniffing your IF to give a waterfall display of or at your current frequency are nearly plug and play.
Actually the common RTLSDR usb dongle and a RasPi would be enough save for the lag.
But
And something like that amp mentioned above. *
And
Leave the 2000 alone. A massive overhaul and modification just isn't worth it. Unless it is.
Just a thought.
*Note" the Radioberry output although a fully formed signal is only on the order of 20-30mw. Then the PA will need a band pass filter. YMMV

Kopcicle, I've come to the conclusion that even though I get bored and look fondly on the ways to mangle a classic into something of my own wild imagination, going against the grain to leave my mark on the world, or a few radios, I just can't bring myself to commit sacrilege. Rest easy, ole boy, she's gonna stay stock, I'm even considering putting the limiter back in (which I did not remove btw).

I think it's the same, the board is upside-down in the top picture. I bought one too, hopefully it will work when I put it together.
