Yep, did that for a system still running windows 3.1!

Yeah, like pasta in the shape your pet, or maybe your face...

The possibilities!

Certainly going to make the annual dickerdoodle contest at PA more interesting.

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.

Been digging around... this would make a pretty damn fine cross band repeater!

Anonymous Coward giving their callsign....

*snicker*

One wonders what the internet would be like if we had to have callsigns on all communications....

KK6MDB, 73s!

For anyone who has not seen an Elecraft kit, they are truly wondrous bit of kit.

With a DIY case, I could make one tough enough for Dual Sport use. Ever since the demise of the Yaesu FTM-10R there are no really good options out there.

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....

I make 110%, roughly

P.S.

I don't know why it is such a big deal, you buy a Beofeng off Ebay/Amazon and it will do all these things as well, for under $40.

Handroids!

Won't be long before commodity hardware can do this.

But I still won't be giving up my Elecraft KX3!

One time or every KW generated?

Because $.70 is pretty damn high price for power, given the average price in mainland US is $.07 to .$19
Even Hawaii the average is only .45.

That is 9X what I pay in California for the first 1000Kw used.

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.

I think that is a subset of 4.
