Have a True cooler GDM 10 RF - RB in enclosed area on lake dock. Is it best to unplug for the winter or leave running with temp turned up? May occasionally get as cold as 15 degrees +.


these units are designed to run in an ambient of about 65-85 degrees. I would turn it off and wait till temps get more constant at 65 or above.

Radio quits after 15-30 seconds


without more detailed info, quick suggestion - thermal fault, if all TX audio works when in this fault condition, it may be fair to assume audio IC is ok and check electrolytic capacitors and dry joints.

When ever i dead key the mic on med rf power i get a humming or bumble bee sound through my talkback same thing on high rf power i changed the coax it helped it for low rf power and tried new mic but had...


Thats because your Rf is powerful on high settings..try taping a AM radio "ferrite bar" to your coax in the back of radio for "RF filtering". Keep your power supply 15 inches away from radio. I recommend unhooking talkback on radios (it always causes feedback). But make sure speaker is good distance from the radio. I'd say 10 feet or so, behind radio. Change external speakers or add one with a long cord.

How to connect an dvd to old tv


they make a small box called an RF modulator. It takes the audio/video signals and turns them into a signal the coax can read. You can pick one up at electronic stores. There usually about 15-25 $.

Panasonic NV-SJ205 Changing Rf ?


ok. This is a really easy one.
All you have to do is hold down the menu button on the remote control for more than 5 seconds, If that doesnt work hold down the power button on the remote control for more than 5 seconds. If that doesnt work hold down the power button on the actual vcr unit for 15 seconds. The first method should work for Panasonic's fine.
This will then display your current rf output.
You can then change the output by using the up and down arrows or the channel up and down button on your remote or the vcr unit.
Press menu button to save or the same button you used to bring up the rf opposition eg power button on remote or the unit.

all the best. Top tech

Need a compositeoutput (F connector) for the Startech SVID4101R


Hi, If your TV has only an F input connector, then chances are that it can only accept an RF (TV/Cable) signal. On the other hand your video/signal source puts out a composite video signal (presumably with audio likewise). What you need is an interface converter or more commonly called "RF Box or RF Modulator". This is a device that embeds your audio/video signal into an RF signal transmitting at a TV channel (commonly 3 or 4). These devices are commercially available. You have to specify whether stereo or mono and what color system is being used in your country such as NTSC, PAL, Secam etc. A fine example is RadioShack's RF Modulator Model: 15-2526, Catalog #: 15-2526 (http://www.radioshack.com). A work around is to use an old VCR where you can plug into its RCA Audio/Video INput your signal source and connect its RF out to the F connector of your TV via a short RG59 Coaxial cable terminated both ends with FP-5 connectors.. You have to select either 3 or 4 (as the case may be) in your TV and set your VCR to VTR operations. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards.
