No no, I know, you would need 2 units, but they could be housed in the same case.

Usually, you need a separate TX/RX antennae, with enough physical separation to keep them from interfering, assuming standard .5 +/- offsets.

Cross band eliminates the interference so long as you didn't pick a harmonic and allows you to mount the antennae near to each other.
And they can be ad hoc, not worrying about having a repeater frequency license. (Totally full where I am)

No idea if TDMA solves any of the issues above with cross band, probably need to read about it more.

Beofeng is getting there, I expect they will do digital for sub $100 in a year or two.

I think the win here is that the Maker/hacker community would be fascinated by HAM radio, I know I am.

This might be the bridge. That and showing them how to make 800w tube amps....

All valid points, but it does get used locally. The local sub-station runs only forward, to protect the grid from a lightning strike.

In essence, when I put power back on the line, it is probably only going to offset the houses in my neighborhood, reducing the draw at the local sub-station.

Heck, I doubt it goes past the 4 or 5 house on the local step down transformer

Here is the thing: when I "sell" back to SMUD, I am getting a small payment, but I ALSO get the usage of that KW I pushed on the wire when I pull it back down later.

I make 10 extra KW at peak solar, I get the money. I use 10 KW of grid power during off peak solar evening-night-morning I don't pay for those KW because my meter ran backwards, and is now running forwards for a net of 0 (zero) KW charged.

It is perfectly fair. I get a small payment when I generate during peak and save them spinning up more capacity, and I get to use them as a free battery during off solar times.

 

Nothing is finished until the paperwork is done.

Working...
