Portable TV arrived yesterday

Picked up this TV which HAS A CABLE TUNER at Overstock.com for $32. Shipping hurt though. It can be powered by 12 volts, has an external antenna port and a nice 7" screen. It comes will all the cables and connectors we need too. This will be the center piece of the receiver.

Some photos of this weekend's successful test

I was very excited to start seeing components arriving in the mail. We got the transmitter first, then a couple of mini-cams. Saturday we started using alligator clips to attach the camera/transmitter/antennas/TV/batteries/switches together just to see our first ATV signal on screen. Somehow it worked! We got a signal on TV without any direct connection. Now that we know it works, I need to start to assemble the components into a small, neatly organized device with hopefully a single power supply and a single power switch. A handheld ATV station! Then we can start testing range.

Transmitter and testing

This week the transmitter came in the mail. We now have all the materials needed to start testing. We also tested the UHF frequency from our house to hanalani schools. It works pretty well, but it disorted the T.V. signal to any T.V.s on the channel 59 (which is the same and the ham radio 434.000) near by. Next we are planning to put together and test the transmitter this weekend. If it works we would have had our first ATV transmit on the air.

Transmitter delayed

Message from Videolynx:

Sorry for the delay. The Z70A's are just going through the last bits of assembly. Should have it in the mail on Monday the 13th or sooner.
