Hi there,

I'm trying to transmit an SD signal from the Transmitter on my sled to the Receiver (hooked up to a Monitor BNC to Phono)

I have my HVX200 on my rig at the moment and I'm using a regular phono cable with a BNC adaptor. Video out from the HVX to a BNC adapted phono lead into the transmitter. However, I'm getting no video signal at all.

Am I doing something stupid? I can't seem to work it out. I also have no other camera to test it.

I'm sure the transmitter would have to accept a signal from the HVX video out.

The Wevi only accepts digital signals... i.e. SDI and HD-SDI. The SD output that a camera such as an HVX would output is just composite analogue video.

This is one disadvantage of the Wevi for lower end video applications.

You'll probably notice that all the lights on TX and RX are green, indicating that the signal has locked on - it just can't display the video.

If you can live with a very short delay, you could run an in-line Analogue to Digital converter on board the rig, i.e. composite to SDI upconversion. But you'll need to make your own power cable for this.

Hope this helps

Thanks Jason, appreciate your help.

I had a feeling that would be the case. Oh well, it's no big problem!

cheapest downconverter is the Decimator by RedByte

read up on IDX at:

I dont really sell them - prices are crashing... I heard that there was a software update in June or so which improved range maybe but it lets you use more than one receiver now. call the factory.
Manufacturers spec sheet: http://www.idxtek.co...cw5hd_flyer.pdf and a review article:
http://www.studiodai...hlist/9306.html the manual: http://www.idxtek.co...nual/cw_5hd.pdf

while I am at it:


There are only a few video transmitters that work well while moving:
(Prices approximate, performance based on personal opinion only) This is an overview for personal use only, do not distribute.

Short introductory document on rentals:
http://wolfvid.com/d...Rates_ _Faq.pdf

For use in the USA:

HD in HD out:

IDX 2008 version:
New digital 5.2 G one frame delay, 50 yard range exterior for clean line of sight, 20 yards with one human as obstruction – Revised Software for 2009 summer: can be received by 2 units. Recapture was maybe 8+ sec from instant crash to black pix when exceeding range, license free, Transmitter-Receiver pair lists $6000.00 sale prices are about $ 4K. Fits between the camera and IDX V mount battery (adaptable for Bauer mounts). Only HD-SDI inputs and outputs, you need 2 standards converter for composite from a film type composite out video tap to composite monitor. 2 IDX work fine together, 3 only with special mods. Many Camera Houses have it now in 2009 summer. Approx.: 150/day. It really does 1080 uncompressed – but bit reduced. Looks great, dies instantly, totally when out of range. Typically a PA with the receiver on a mast follows the cameras around to keep range under 20 yards. Camera operators may not drape their body over the Tx or there is no radiation of signal. Info and 20-page manual:
Official press release:

PR rag says: Unlike other wireless camera system systems that make use of MPEG-2 or wavelet compression the CW-5HD transmits wireless full-bandwidth uncompressed HD-SDI and SD-SDI images over short distance, with very little latency (they say less than 1 millisecond delay). It supports all ATSC HD video formats with two channels of embedded audio.
NOTE: as of August 08 it does do 23.9 at all scan rates.

Digitran from Boxx – digital transmission means perfect picture always: indoor range 135 feet, 25 yards outside, 8 frame audio delay, FCC Part 15, No license required: Legal to use anywhere, 9-14 volts, built in antennae, very convenient small flat package.
Outdoor range 45% of Modulus = 75 feet.
Indoors stage range: 140% of Modulus = 300 feet
Picture quality is always excellent. No flicker, no fuss. No complaints. Built-in antenna. Great for stage use. Has 380 millisecond delay (12 frames pix latency). Audio delay electronics to feed line out is included in rental package. There is no license necessary and they can be used by anybody anywhere under any circumstances for any use. Range is still limited in 2006,7,8 for this model. Price pre 2007 unit, used ones for much less.
Complete Package for rent from Wolf Seeberg Video.

2007 model (with external antennae) is available outdoor range 300 yards plus, legal in USA and worldwide price: $ 6700.00. Same delay makes it a difficult learning curve for directors for most on set uses. Made in Great Britain.
20 page Manual
http://wolfvid.com/d...ital_manual.pdf http://wolfvid.com/d...N_ONE_SHEET.pdf

Digital Video Transmitter – IDX - Wevi
This digital transmitter always has a perfect picture: License free operation. WiFi 5.2 GHz. Discontinued in 2007 but still available. Hard to find except at some rental houses. Same issues as the early Boxx version but slightly less range. 10 frame pix latency. 2 receivers have to be 10 feet apart. 30 page manual

2009 Boxx (not available in summer 09)

Shown as prototype production model in LA in March 2009 with 1 msec (a frame takes 30 msec) delay and a beautiful perfect picture all the time. License free. WiFi freques in the USA, wide choice of freques and power outside of the USA. Slowly gets noisy in a mosaic sort of way when moving out of range, that’s a good warning that IDX does not have.
Range: 70 yards outside, 20 yards through one human body line of sight between Tx and Rx. 30% more than the IDX. One Tx can transmit to as many Rx’s as you like, quicker recapture (4 sec. vs. 8 sec.) than IDX after out of range wanderings of cameramen, looks very good, they admit to some bit reduction but no compression. Receivers will switch between multiple transmitters. Approx. prices $7K for Tx and Rx pair. Downconverter built in. Transmits HD and receives HD and SD or Transmits SD and receives SD.
Not available by august 2009 (British Calendar) with 2 receiver types:

1.) Small and lightweight for handheld monitors,

2.) Larger with 5 diversity antennae, more expensive, higher gain antennae for better range, delivery late 2009.
This receiver can be Gen-locked to your system (decks, truck, router, etc.).

Expensive larger Rx has sophisticated capabilities: you can link many units with coax, place them a distance apart and the master RX will choose which is best switch between Receivers and send best pix out. Whole stadiums or cities can be covered this way just like cell phone technology does.
You can feed the Tx with HDSDi any frequency, or composite from video assist. The Rx will output the same signal as the Tx; and the Rx will simultaneously output a down-converted composite. NTSC or PAL.
Band used is the USA 5.2 WiFi license free, or worldwide 4.9 – 6.1GHz some at higher power (not working in June 09).

Wolf Seeberg video will be the first dealer to have these in the USA

Note: Most Tx might induce noise in audio recording and sometimes in video if mounted directly on small portable consumer DV type cameras. Most Tx (like PDAs or walkies) induce noise in professional microphones less than 3 ft away unless they are the new CMC6 Shoeps or newer Sennheisers
Wireless HD, no delay, good range Transmitters $$$

For cameras: F23 3 chip, F35 1 chip PL (12K/wk w/lens+fiber), RedOne 1 chip PL ($20K to buy without lens)

HDSDI with slight (not noticeable?) compression: There are 3 major TX-Rx manufacturers in the U.S. – There are 2 in the U.K. Purchase costs range from $60-$100K.

GMS – San Diego – rent from Wexler

(M2T-C) or CMT 2.5 sec (?), boot time – golf course range = 2 miles – Receiver has 1694 (thinish) coax to antenna, AVC compression technology with one frame delay covers all the SD and HD formats up to 1080P

HD transmitter with HDSDI input

HDV Compact Transmitter lower price for news

Another manufacturer: http://www.trollsystems.com/ seems to be Helicopter to ground generally

Gigawave Limited -- Great Britain with the coolest web page

http://www.gigawave......m Clip-On.pdf

Link-- Great Britain rental: RF Central


Rental and Service Co: RF Central in Pensylvania, 3G in Texas??, AVS in LA.

Picture Quality:
The picture of all these Broadcast systems is excellent and perfect always, even though it’s more compressed that the on-camera tape/disk. Imperceptible color reduction is the first to occur on extended range reception. Blockiness and freeze frames don’t occur for 2 miles (?) in open-field use (systems vary as to warning signals). A downconverter is necessary for SD assist.

Legal: There seems to be legal frequencies around 5.7-8G that are license-free in the USA. The stuff above can use this. There are 2.3 G frequencies for which it is easy (for established rental Companies) to get licenses for local use.

Wireless remote camera control:
Once you commit to a $4,000 per camera weekly rental, you may give serious consideration to the addition capability of wireless remote camera control. All Menu functions and iris (but not focus or zoom) can be adjusted with these remotes while watching remote monitors. These are manufacturer and Camera specific: If Sony F35 is covered is questionable and needs research. You can use a 3 motor FIZ of course. Camera assistants are used to dynamic iris/Fstop changes. If the DIT/VC has that control less communication is necessary.

Re communication: Get a duplex wireless headset system for technical dept as usual in video production. Walkies are so Stone Age.

Camera control:
A return transmitter at the video receiver site sends control signal to the camera. These are often built by different manufacturers than the video link. Careful checkout as to range and functionality is necessary. Most would control all menu functions and Iris. None control focus/zoom.

Setup and labor:
For 300+ yard, simple one stage or open air (no walls or concrete) reception, a one time set up is possible and an engineer may not be necessary past the first day. For a complicated action show with shooting in concrete structures and many location changes and widely spaced cameras, a microwave operator (650/10 or minimum L600 tech rate=$43/hr) is a necessity. Here is what he does: There are many options of connecting 3-6 antennae for diversity receivers that optimize results. It’s not that complicated, but needs undivided attention at the critical busy times.

Wexler makes a camera control for Cam remote for: Sony 150, 750, RCP etc might take extra box on camera.

GMS makes camera controls.

3G makes a camera control with additional box on camera for LDK 6000 – 8000 – 1500
3G can get FCC: STA permit for 2.3G per city per week. Credit: 8 Camera: “Celebrity rehab.” Can do 5.8G license-free, prefer 2.3G.

HD digital transmitters draw about 2A+, so power for camera is an issue.
Read this: http://wolfvid.com/d...nd_chargers.pdf


SD Digital, no delay, good range transmitters:

Works the same way as HD (best with diversity antennae), costs about $2,500/week per camera, from Wexler made by GMS – no camera return available as of now, used by a lot of reality shows. Perfect picture. 200mW

Also have an SD system in same box as HD (cheaper) as above.

2.4GHz less than 40msec

Domo British: Solo2 and Solo4 rents 500/day
Not broadcast quality (fine for video assist though), MPEG. This is a British made TX 2”x6”x12” that draws 1A gets hot and has only a one frame delay. Not sure about USA licensing. In 2007 it costs $ 20K and is made to order after advance payment. Delivery 6 weeks. Outdoor range is 4000 feet for 100mW with a 3.5 foot long helix to receive(not much) and it has a perfect picture all the time. 2000 ft range with 4 db omni receive ant. You can use it in the USA legal 2.4G band at reduced power with much less range (slightly better range then the analog part 15 stuff from Avalon or Transvideo but with a perfect picture). It can also covers the tightly controlled new USA broadcasters ENG channels for TV station use around 2G. 2250—2500MHz. Awkward receiver with lots of small filter boxes that help in the cities. Likes 2 long Helixes (3.5 feet) to receive. You can set up as many receivers as you can afford and switch between them. Has longer indoor range than the UHF or FM stuff due to helpful reflections. Needs 10 Meg spacing for 8 Meg wide channels that do not bleed into each other.

Range is 2 miles on golf course; helicopter range is 4 miles; 30 miles with an amplifier. A solid combat proof packaged unit with special diversity receiver and most excellent custom antennae. For a helicopter or other long range video link there is no choice but the FM2 equipment. This is better than any other analog microwave because of the diversity receivers.

Coherent’s 900MHz
microwave FM analog system uses special diversity receivers, that means a lot less flicker. A special version can burn TC in picture. We get 1.5 miles on a golf course out of this system after we tweak it; 3 miles on a helicopter. Often problematic in the big cities as there is masses of 900 stuff around. There is no need for a 2nd guy to point receive antennae unless you are at the ragged end of range. These systems are now produced by new owners – Halcyon halcyonmicro.com or http://cocom.com/pages/pro.htm - with higher prices. We have them in rental packages as a fully legal system in the USA for any use – No license required, FCC Part 15 licensed. These systems work better than the stuff at 2.4G because of lower frequency and diversity reception. But in the big cities 900 is full of junk and range will be shorted to half in most downtowns or commercial-convention areas. Rx antennas are larger than 1.2 G.
For rentals check: http://www.wolfvid.c...ntal_900Mhz.pdf
Manual 40 pages
We have some used ones for sale.

WSV Point to point 2.4 link
This is a 1 mile video/audio link in the USA to be used under Part 97. approx .8 watt. Works best with fixed antennae (non-moving) pointing at each other. If you use this kind of system with a moving Tx the flicker is so persistent it’s annoying to the extreme. There are versions of this for overseas use with 50 mile range. Simple to set up. No technician needed. Often this becomes part of a repeater system that looks around one corner or over one hill. Available for rent (with 2 beautiful small Helix antennae) or sale. There is a wide range of commercial antennae available for reasonable prices. 2.4 in the cities is useless now as there is so much WiFi that destroys the picture. Approx $ 200.00 for the pair Tx-Rx. Sometimes this page works:

Avalon 2.4Mhz Diversity,
1 Watt (for overseas use) with 1 mile range. http://avalonrf.com/...x500_tx600.html Very low power version available for USA with minimal range – approx 50 feet. TX600 Series comply to FCC Part 74 and Part 90. You need to put up 4 pieces of 4” square flat panel antenna 2 feet apart – nicely made, pro-connectors. www.Avalonrf.com . Not good on a stage covered with chicken wire. Occasional highlight reversal like Coherent. Coherent range is TWICE. WSV FM2 is TEN TIMES. Penetration of sheet rock not good Ouch! Not much good in cities nowadays there is so much 2.4 stuff that there is no room for this to work well in the urban areas of the wired wireless world. Factory service varies as to permanently changing ownership. Price: minimum package US $7200.00. Not really sure if these are on the shelf all the time. Avalon changed owners in 05. If they don’t have it in stock I do not know if they can deliver. Similar stuff is made cheaply and poorly in China. Someone said Avalon is not in business anymore in 2009 ??? better check.

Transvideo 2.4Mhz Tx-Rx
Same problems as all part 15 low power Tx in that band of freques. Bad in the cities that are full of 2.4 stuff, OK in the boonies. Still it flickers wickedly when the transmitter moves because no diversity receiver. License free in USA. http://www.transvideointl.com/ available thru B+H photo in NY or direct http://www.transvide...ducts/titan.htm , or from the manufacturer/repair facility in France.

Teletest, Britain

sell a powerful 500 mW 2.4 version that is not OK in the USA except possibly for Part 97 use. Looks like nice packaging. Will flicker a lot with moving cameras. With a portable 7” LCD receiver. has to flicker badly on moving Tx. http://www.teletest....cts/OZL7007.pdf

Another Brit Company reselling cheap Chinese product under their own name?? – They have a diversity receiver oriented towards the toy airplane market (of course its easy to receive TV from aircraft, there is no multipath) http://www.blackwido...ity24new1.html# you have to match Tx and Rx. Don’t expect a Rx to work with other stuff just because its on the same frequency. Made for BWAV, Airwave or Felsweb transmitter. (not sold in the USA) TX Frequencies: 2410, 2430, 2450, 2470 http://www.blackwidowav.com/

HP Video 2.4
Looks like a Chinese repackaging job. Approx. 3K Tx-Rx flickers as much as all the other analog 2.4 stuff. Trouble if there is a lot of WiFi, Blue tooth, wireless phones around. Easy packaging for vid ass. All these 2.4 TX will do much better with circular polarized receive antennae. F 2490 MHZ,2390 MHZ,2370 MHZ,2470 MHZ,2450 MHZ,2430 MHZ,2410 MHZ,2510 MHZ or 1240 MHZ,1040 MHZ,1010 MHZ, 1200 MHZ,1160 MHZ, 1120 MHZ, 1080 MHZ, 1280 MHZ. Not sure how these can be sold or operated legally in the USA.


High-gain 2.4 receiver antenna
The Black widow people sell a high gain circular polarized patch antenna. Not easy to find. These make a huge difference in reducing flicker. None of the 2.4 guys know of this. http://www.blackwido...chantenna1.html

Part 15 means: http://www.access.gp...47cfr15_01.html

For continuous camera power, check this expensive stuff:
http://lentequip.com...terybridge.html $ 750 and Keslow Camera makes a small nice splitter box. Of course we can make you a $ 65 4 XLR “Y” splitter cable and you pretty much get the same thing.

and a Red Camera back plate
http://www.lentequip...edsplitter.html also 700 bucks geeez, all that to make it IDIOT proof? or we make you a 4XLR “Y” cable with diodes for $ 100 !

Now the impossible (multiple WiFi) with long latency:
To transmit around steel and concrete buildings, transmit around corners and around mountains and tall buildings: If you don’t mind a 12-20 frame delay you can use a British 2.4 and/or 5.2-5.8 digital WiFi system that has multiple receivers joined by CAT5 cable that can receive up to 6 cameras and switch receivers automatically to follow camera positions. The distance to as many receivers as you want has to be at most 80 feet. The guys doing this are based in LA and London and regularly do Reality shows. You need setup time and a lot of cabling but the system works pretty well with resolution good enough to watch but not put on TV. Needs a technician of course. Has not been recorded to computer as a file yet. Can be recorded as NTSC video out from a computer on the CAT5 cabling. Call us we will put you in touch.

Hey - there may be mistakes in this and its only a personal opinion anyway, forget getting mad or suing me this is just ONE experiment by one person.

Note: none of the legal restrictions in the USA apply for sales outside the USA. We sell to Europe, Canada, South America and Asia. The Coherent Microwave and digital microwave systems are legal to use in the USA and license free. Call us for details.

Our rental packages are very complete and, as always, it is the accessories that make a system work smoothly. You get the best antennas and great phone and educated native English speaking staff support. You got to read the manuals….

Talented, persistent, ingenious amateurs can do well by studying the very extensive manuals. Camera people need to read the manuals and to tweak receive antenna position (at least up and down) to optimize reception. Fine tuning Receivers is not an art, but is a great help for UHF transmitters. Inflated egos do not make electronics work better. Brains applied to the situation do more than cell phone help calls.

Chinese “stuff”
Now there is also a lot of cheap Chinese “stuff” in the microwave range appearing on the Internet. The advertisements are way optimistic. That nameless stuff has very short range and there are no repair possibilities. There is no diversity available, which is a must for FM microwave to reduce flicker (multipath). Some Video Camera rental house rent it in LA. You need a part 97 license. Don’t bother except for a baby monitor at home. 2 w 2.4 G: http://www.asianwolf...era-2000ma.html
Not sure if this could be used legally in the USA at all. If you step on the frequencies the TV stations use for their truck you will get found very quickly.

About the Wexler and VER Chinese stuff they bought from a USA repackager:??? I heard bad reviews from many and positive reviews from newbies mainly??? Have not seen it but its mainly low power cheap microwave stuff. Both Companies officially say to limit it to 40 feet use. Both give it away with a larger reality camera package. Customers like the convenient 4 button receiver. I heard neighbors were complaining of their home WiFi being disrupted.

Tandem receiver
from Canatrans not yet ready for Modulus reception in Aug. 2009. OK for Canatrans only, not other UHF Tx !!!, Very slightly more noisy and slightly less range than Sony 1041. 5-30 volt. Has a bracket to mount Sony “M” style batteries on the side. PAL and NTSC.
Cost $ 3300.00 approx. nice and small.

7” LCD Handheld TV

Receive antenna

Prices and everything else constantly change of course

New Regulations: UHF transmitters were to be used outside the USA only till 2006. Now there are regulations in place where a Producer can get permission to use these for video assist in the USA. It’s a bit of a procedure and we are waiting for various producer’s interest groups to give guidelines..

CanaTrans has better picture and slightly better range than Modulus. Has easy menu adjustable video gain for night imagery, adjustable power output, channel 20-50, built-in volt meter, low voltage cut off, no video at input battery saver cut off, rachety audio included – made and sold from Canada. Not for use in USA. NTSC or PAL. Well made, good service, rarely break, all microprocessor controlled and aligned for minimal maintenance. Probably 200 in use worldwide. Check hidden files US $ 4000.00

Modulus 300o discontinued since 2002. Resuscitated in May 2008 and available for non-USA use. It is the most popular. Special version can burn time code into pix or transmit (poor) audio. Any TV can receive the Modulus. Not for use in USA. Repairs used to take a long time. Print your own manual from our website. Really a good read. If you know that stuff you know more than any one person in the world. US $ 2200.00.

Dynawave VTX-100
David Hable at Cramped Attic http://www.crampedattic.com/ in Canada (604) 254-8619 hable@telus.net sells this small and light prototype Tx. Specify that you want a BNC antenna Connector. Use our ½ wave antennae – much improvement over the junk antenna they sell. Also specify power in connector, all are possible, just match whatever you have – avoid Hirose, if you have Modulus cables you have a choice now to go the Canatrans Fisher connector route which is much more reliable (and only slightly more expensive). Channels 14-69 NTSC. 10-36VDC. No power ON/OFF switch – that’s good except for steadicam use. No auto off. Lower power and much less range than Modulus as of Nov. 2007. It’s still a work in progress it seems. Dave is very customer friendly even if he is slow at times. $ 2000 in Nov 2007
