RJ, et al,
I have a suggestion for a (future) enhancement to the wireless Tx... A Power over Ethernet option.
I'd like to mount the transmitter unit under the eave at the front of my house & run a cat5 cable to it from inside the house where the PC & USB dongle will sit (the cat5 cable would be a permanent through-wall installation). It would be much easier & neater to provide the power to the Tx through the ethernet cable. When I'm setting up the display, I'd just plug in a single cat5 cable between the jack mounted under the eave & the Tx unit (rather than having to mount the Tx power brick near the unit, run a power cable to it, etc). Of course, on the inside of the house, I'd need an adapter cable (or a specially-wired wall jack) to inject the power, but that's pretty simple (and maybe a coop opportunity).
As I said above, this would greatly simplify & neaten my transmitter installation, while providing protection to the wall wart by keeping it inside the house with the computer & dongle.
The only downside (I can see) to doing this is the possibility that the wall wart would be attached directly to the Tx unit and back-feed the cat5 cable - depending on what the cat5 was connected to, it might short out the power supply. I think this could be overcome simply by placing a diode in series with the cat5 power feed in the Tx unit.
Anyway, just a suggestion for a future enhancement - humbly submitted for your consideration.
