Will Digital Converter Plug in to 1993 Sony Watchman?
I have a Sony Watchman purchased in 1993 that also has a radio in it. It has an antennae, and one switches channels for TV or radio by turning the dial. There is no remote control, in other words. If I get a digital converter box, will it even plug in to this television? I would appreciate any guidance you might have, even if the answer is that it isn't worth obtaining a converter box for the television part of the Watchman.

Everything is digital now. You will need a digital converter box. You will connect an antenna to it, and then connect the box to your tv. The box will come with it's own remote. Your tv will be set to channel 3 or 4 (depending on the converter box you get), and you will control the stations with the remote that came with the converter. You can get them at any electronics store.
are three ways you can connect a DVD player to a TV. Component video
gives the best picture quality, but requires 3 cables for the video
signal alone. S-video needs only 1 cable but it isn’t as good as
component video. Composite video is the easiest connection to make, but
gives the lowest picture quality.
You will need that converter box for the digital to analog system plus a out odf door antenna...radio shack is good place to ck...also ck out Amazon.com & eBAY ck this outat Amazon.com http://tinyurl.com/m7xo528 for box antenna here http://tinyurl.com/p2tsbra
Radio tuners receiving AM and FM channels/broadcast MUST have some sort of antenna connection. For local channels a paper clip will work, but for more distant channels, use either a better inside antenna or purchase a outside antenna as needed.
you do not "set" swr.you cannot set it on the radio. the radio can tell you what yourswr is. it can take an swr measurement. swr has to do with the antenna system. in order for the radio waves to radiate from the antenna properly, the physical length of the antenna must match the length of the radio waves. if the antenna is too long or too short you will have a higher swr ratio. the higher the ratio the less energy will leave the antenna. but that energy needs to go somewhere, so it goes back into the radio which causes damage and can ruin a radio.
first turn the channel to 20. then switch the meter switch to CAL. then key the radio. while keyed, turn the CAL knob up until the needle in the meter gets right to the CAL Mark. next flip the meter switch and key the radio. where ever he needle is, is what your swr is.if it is more the 1.5 that's getting high. if its over 2 you are in the danger zone. if its over 3 you are damaging your radio. you must repeat the calibration proceedure for every channel.to figure out weather your antenna is too long or short, you compare the swr readings from channel 1 and ch 40. if the swr is higher in 1 then on 40 the entenna is too short. if its higher on 40 then 1 its to long.
The on/off switch could be dirty or broken, and will need to be replaced, if bad. You might be able to spray some electrical contact cleaner on it to get it working again, if it's just dirty or oxidized. Other than that, the unit could have another major problem that would require servicing. Oh, the power jack on the watchman could be sprung or bad, not allowing juice to the main board. Good luck and hope this helps.
Any of the digital to analog converters should work. Connect the converter RF OUT to a COAX cable, connect the wire in the center of the COAX cable to the Sony antenna with an alligator clip type patch cord. Tune the sony to the proper channel (3 or 4). Voila!
You don't need a digital antenna; any indoor UHF/VHF antenna will work. The antenna and the TV both connect to the converter box, not to each other.
rabbit ears (UHF/VHF) antenna with flat wire (300 ohm) connections can be hooked up to the coaxial cable that goes to the Antenna (RF in) jack on the converter box by using a balun (Radio Shack catalog # 15-1297, about $8). If you have an antenna with coaxial cable already attached, you don't need the balun.
To connect the TV to the converter box, you need an adapter that has an F jack on one end and a
1/8" plug on the other (Radio Shack catalog # 278-257, about $5). The
1/8" plug on the adapter goes in the external antenna jack on the TV, and
the other end connects to the coaxial cable that goes to the TV (RF out) jack
on the converter box.
