JDirckze Posted May 19, 2008 Report Share Posted May 19, 2008 Hey all, The show I'm on at the moment are looking for a solution for enabling the field producers to have wireless LCD monitors. I brought my own little wireless monitor setup, which was a very small transmitter and combo receiver/TV (think little hand held baby monitor) but at the moment it is pending repairs, and the producers have complained that the monitor was too small, and not 16:9 Production have sourced some cheapo LCD monitors, and at the same time bought some cheapo video Tx/Rx, but they were very unreliable, and relied on a stupid amount of batteries to power the monitors and Rx. The same with the Tx, where 8 x AA were needed to be strapped to the camera, versus my solution which was powered from the camera itself. In the end, the setup that production bought was totally unusable. Anyway, I know this is not the usual type of thing sound guys deal with, but I was wandering if any of you out there have been through this and could point me in the direction of decent solution. Cheers, Jason Quote Link to comment Share on other sites More sharing options...
jason porter Posted May 19, 2008 Report Share Posted May 19, 2008 Hi Jason, I have used these recently- http://rf-links.com/video_senders.htm They are a little dirty, so if you use an RF hop to camera, make sure the receivers are high quality. Along with a Delvcam LCD monitor/Tuner unit, it is a cheap solution. I have also heard good things about these guys- http://www.blackboxvideo.com/video_sender.htm I also have one more option, but I can't find the website, I'll update you later. On my current production, we are using 2 Modulus senders...surprisingly, they work well and have not interfered with my RF equipment!!

JDirckze Posted May 19, 2008 Author Report Share Posted May 19, 2008 Thanks for that Jason P, those links are very useful! Quote Link to comment Share on other sites More sharing options...
JDirckze Posted May 20, 2008 Author Report Share Posted May 20, 2008 Thanks for that Scott, both options look awesome, but I know for sure production won't shell out the $$$... We're on a super tight budget. Quote Link to comment Share on other sites More sharing options...

studiomprd Posted May 24, 2008 Report Share Posted May 24, 2008 " 97.113 of the FCC Rules prohibit the use of Amateur Radio Frequencies to further any business purpose. " the FCC and radio amateurs are pretty agressive at going after intruders in Ham radio spectrum... pretty much makes using it on production both illegal, and risky!

wolf Posted May 25, 2008 Report Share Posted May 25, 2008 mike michaels is totally correct of course. and amateur radio is a great hobby, just think you can reflect radio signals of the moon and receive it on the other side of the earth. here some guidance: LICENSES The Microwave frequencies between 1240 to 1300 and 902 to 928 Mhz have been allocated in the USA by the FCC to Amateur Radio Communications under Part 97 available on the net at: http://www.arrl.org/FandES/field/regulations/news/part97/ You can own, sell, rent and receive on any equipment without a license. Only for transmission does the operator have to hold the easy-to-get “No-Code Technician Licenseâ€. You can take a 2 day course at the end of which you’ll easily pass a multiple choice test (>10$ fee) to get your license. No Morse code to learn. Alternatively, read one of the little paperback manuals listed below and get tested anywhere as described in these booklets: Gordon West’s Amateur Radio No-Code Plus Novice and Technician Class Theory Cost: $9.95 Master Publishing, Inc., 14 Canyon Creek Village MS 31 Richardson, TX 75080 (214) 907-8938 Radio Shack has a book with the license application included: Radio Shack: No Code Plus Index No. 622417 Courses are offered free by many Red Cross stations or for a minimal fee by Amateur Radio clubs or stores. Look in the Yellow Pages. A good commercial school in the LA area is: Gordon West Radio School, Inc., 2414 College Drive, Costa Mesa, CA 92626, (714) 549-5000. And on the WEB: http://www.gordonwestradioschool.com this is a good place to start informing yourself. Also: The ARRL (American Radio Relay League) distributes a no-cost package on amateur radio with all the information you need to get going towards a license. You will learn a lot in the process and have the chance to meet many new friends. You may contact the ARRL as follows: Telephone Toll Free 1-800-326-3942 Mail: ARRL EAD 225 Main St, Newington CT 06111-1494 Telephone (860) 594-0301 FAX: (860) 594-0259 E-mail newham@arrl.org Compuserve: 70077,3373 America Online: HQARRL1 http://www.arrl.org/ They also publish a useful book: Technician Class License Manual for Novice Class Licensees ARRL Bookshelf #4181, $6 for orders: (203) 666-1541, Of course you can not use these frequencies for any commercial endeavor. These are amateur radio frequencies and you must obey the laws and conventions established on these bands. The operator of the equipment is the responsible party to follow the law. Also interesting read: http://www.hello-radio.org/becomeaham.html there are a lot of old time soundmixers who came out of the military and Ham radio and have a lot to offer, just ask MM any questions he will be happy to talk about propagation which is something reality folks have not even heard of mostly. w.
