The PXL-2000 has an RCA jack on the back where it puts out and RF signal

that is suitable for connecting to the antenna input of your TV or VCR.

The word "suitable" applies to the signal and NOT to the jack,

because the proper jack for an antenna connection is an F-type

connector. Thankfully, the PXL-2000 came from the factory with the

proper cable for this connection. Even if you don't have it anymore,

adapters are available from R.S. and elsewhere that can take care of this.



The RF output is "standard equipment" on the PXL-2000. If it did not

have at least that, it would be impossible to watch on your TV the

masterpieces you created with it!!



The reason people want the "baseband video and audio" conversion is

to allow them to connect the PXL-2000 to the inputs of a portable

battery operated camcorder, to shoot "on location". Camcorders never

had "antenna" inputs on them, and they never will.

If you can always carry with you your VHS VCR and can always find

110 Volts to plug it to, then you definitely don't need the conversion. 



Using a camcorder for recording solves a lot of problems at once:

You are no longer limited to just 6 minutes of recording before

you have to change tapes (8mm runs for 2 hours at SP, even 3 hours

with 180min tapes). Furthermore, the "quality" of the result is

clearly superior. You will not have the jitters, the loss of resolution

and the dropouts seen from audio tape recordings. With Hi-8, and even

with 8mm tapes, you can get a recording that looks as good as the "live"

pictures you see from a PXL connected directly to the antenna input of

your TV.
