My System: 1.2M prime focus with SA58 H-H receiver-New Wave 9000 BP MK II | well the RF modulator project has gone well. I ended up removing a second modulator from and old matsui RD 600 analogue receiver as I could not get the first one from a grundig GDS200/1 to work. The only difference between them is the number of connections they have, the grundig has 8 and the matsui has 5. The connections on the modulator from the matsui are marked up as follows- 1. V - Video 2. A - Audio 3. MB - 0-+5V switching for modulator. If the receiver was in standby I found this to be at 0V. when the receiver was switched out of stand by it went to 5V. 4. NC - this was not used in the receiver. Ive not used it. 5. BB - +5V antena loop-through/pass-through. How I built it The power supply was going to be built to the diagram on this website but I made a few changes to it. I did not fit an LED and I used a slightly different capacitor because I could not find one that was of the same value shown in the diagram. 3 & 5 on the modulator are connected to a +5V supply, the shassi go's to ground. The video & audio go to 1 & 2. Now that I've got it working I plan to put it into a small terminal box & stick the componets onto a circuit board just to tidy it up. This picture shows you what it is like at the moment. RFModulator.jpg Good luck if you try it & if you need some advise let me know I might be able to help. | ||

 Just out of curiosity, is it not a Stereo modulator then? | |||

My System: 1.2M prime focus with SA58 H-H receiver-New Wave 9000 BP MK II | unfortanatly stereo is not an option with this method as you only have one audio input. your tv my split the sound into two channels but it will still be mono as the original source of sound comes from only one channel ( the left or right audio output on the back of the DVD player) I Dont know if the pace modulator accepts a stereo input, you would need to remove it from the receiver and have a look at the connections, I'm guesing it only has one channel. | ||

My System: 28e, 19e, 13e, 30w | For stereo sound you'd also need a NICAM encoder, and I don't believe they're easy to get hold of/make/buy! Could always ask your local cable TV company (ah local, those were the days!) | ||

 Whilst a lot of new kit comes with MONO OUT on LEFT (great for your project) - you could consider making yourself a simple stereo>mono affair from three resistors  Then you can hook your RF MOD to any kit. By now, maybe you are already thinking "if I have RF, then I could hook this up to the house antenna and pipe it everywhere" LOL ## DEVICE L OUT o)----------[R1]-----------\ ############################ ################################# \ ################################# X-------------------[R3]------------- > GND ################################# / ## DEVICE R OUT o)----------[R2]-----------/ ############################ R1, R2, R3 = 10K Basically, introduce a 10K resistor on both the LEFT and RIGHT signal (twist [edit: solder] the free ends of R1 + R2 together) - then twist [edit: solder] R3 to that junction. X is the tap point for audio to the RF MODULATOR (the other end of R3 goes to GROUND (L+R shield). The ##### everywhere are there only because the forum dont like spaces. . | |||

Llew he's just build a great whotnot from spares and your happy for him to twist cables together. Shame on you.  ]Better go back to my post and say SOLDER the connections, LOL. . | |||

Fighting the evil 3 Dragons under the Don Quixote banner,Sir Llew persevered where others failed | LOL, just saving satscaner 30p You can easily verify that you're maintaining stereo in the unit you're taking the output from (or other equipment that may be connected to it) by connecting the L&R leads together. It'll prove that it doesn't cause any loss of stereo. *satscaner - A nice little job there m8, keep the capacitors close to the regulator when you put them on a board, or you might get some instability. And don't forget the other small value capacitor, this will stop HF interference. Llew | ||

My System: 1.2M prime focus with SA58 H-H receiver-New Wave 9000 BP MK II | Im having difficulty getting hold of the low value capacitor's maplins dont have them and RS seem to have stopped stocking them. I could try CPC or farnell but then I'd need an account with them. | ||

Fighting the evil 3 Dragons under the Don Quixote banner,Sir Llew persevered where others failed | The capacitors filter out different frequencies depending on their value - put simply, large values (electrolytics) smooth out any ripple on the power supply, small values such as the 100nF one will cut off high frequency interference that may be picked up on the line.
