Use this to keep your analog TV's truly analog:

I've got a few of these, perhaps they've been discussed before. Now with the DTV transition, I think now is a good time to inform those who want to still use their old TV how it was meant to be. I like the idea of the TV doing all the work, that is, no cables hooked up to it, no converters etc. While the days of the old TV being independent and receiving signals without any other source are nearly gone, heres something I think all the TV guys should own if you're like me:

Its small low powered UHF transmitter. Transmitts on channels 14-31, channels adjusted via potentiometer on the unit. Its actually a pretty decent little transmitter. In a metal case, self contained power supply, totally analog (lots of resistors, transistors and caps) so its completely serviceable if it ever breaks down. No chips or digital microscopic parts on the board like whats inside the converter boxes.

I will say one thing, when you first power it up, it does want to drift off frequency a bit, so you'll be touching the fine tuning of your TV set a few times through out the hour. After its been on for a few hours, its nice and stable. I leave mine on all the time, and it does have very good range. They work best on RCA sets because of the way the IF is tuned. You'll get some intercarrier buzz though any zenith tube type set using this box, which can be aligned out of course. Another plus is that you can adjust the luminance signal, and sound signal at the transmitter, and also has a switch so you can transmit a cross hatched test pattern, which is pretty nice. I have three of these hooked up to three converters of some of my favorite channels. This way, if I want to watch an old set (having UHF of course), I simply hook up the loop antenna to the set, tune the UHF dial and the only cord going to the TV is the power cord, which is the way I like it. Just thought I'd pass the word on. For what its worth, I used to see TONS of these on ebay from numerous sellers. Now, it appears that there is only one seller left. I suggest you grab them before they are all obsoleted, which is probably going to be very soon.
