  1. More than happy to beta test a unit for you as long as you don't see it as a conflict of interests. Matt
  2. Thats why I abandoned the airwave diversity receiver. I made a couple, they worked fine but the sensitivity varied so greatly from receiver to receiver it was ridiculous. I'm back to a better quality consistent receiver with the intention of working anywhere from 2400 to 2483. Matt

    RSSI inside this RX unit ?

    Hehe, thats the same receiver that is inside BWAVs diversity receiver and that same receiver can from comtech has been the industry standard 2.4ghz video receiver for at least the last 4 years. Matt

    Play with B-Flys all the time at work. We needed a field programmer on the cheap, you guessed it. Butterflies. They must produce those things by the 100's of thousands. Invaluable learning tool plus there are a lot of free compilers out there as oppposed to pics and picbasic or stamps. Matt Klarich
  5. Yea, that was on rcgroups. Too many forums to keep track of... Matt
  6. Oh twin, did I mention I'm working on my headtracker as well? It doesn't use the buddy channels on the transmitter, costs a little more but well worth it when I detail the advantages. Shhhh... Matt
  7. My story I repeat everytime someone thinks they need more and more power is that using a 15dB Omni I received video over 15 miles away from a full-scale airplane. The full scale had a 1 watt transmitter with a standard 2dB rubber duck antenna on it. The more power you put out, the more you multi-path, the more you interfere with yourself, the more you need my diversity receiver! Matt
  8. Terry, didn't take it personally, just wrote that email in a hurry during lunch earlier. Unfortunately other things took priority over my hobby last year, wish they hadn't. Just think of all the knowledge you gained by building your own Matt
  9. Terry, I developed and marketed the first hobby diversity receiver over 2 years ago. I've been wanted to improve upon its design ever since, unfortunately personal issues kept me from being able to do that. About a year ago I came around and I was asking people what they wanted to see in a new design. Those ideas and a few more are what have been floating around and are now once again being compilied. These ideas are nothing new to me and I'm just trying to make sure I give the people what they want at a price that the average hobbyist can afford. If I want to make big money I'll beef the unit up, add more bling to it then you'll ever need and sell it to the government. My electronics business is a "Hobby" business for me, I work as an electrical engineer/circuit board designer all day at a scoreboard company so this isn't my primary income. I love AP and want to do my part to get other people interested, I know, sounds corny but it is true. Matt
  10. I'd like to make it so it can run anywhere from 6v to 12-15V so that covers the 3S lipo setup. If I use a cheap linear regulator it just means I'll need a lot of heatsink for the regulator. The super duper cheap units receive sensitivity will be the same as the high end units, mostly the cost will go to features and expandibility. Would love to make it so you can have a main box that manages a couple 2.4ghz receivers as well as some 900 or 1.2ghz units. Matt
  11. Hey boys and girls, I just got my butt back in gear on my new diversity receiver design this evening. I haven't touched diversity since I made my first design 3 years ago that I sold through BWAV. I'm back at it though. I've been itching to make a couple different designs with different features. Design 1: Super duper cheap -I want to make a unit that I can sell for $149-$179. I know, sounds a little low but it is do-able. Especially with the new airwave modules I am playing with. So many people start messing with aerial video and shy away because of interference problems. I want this to be like the cheap 4-channel FM transmitter you get with the screw together ARF from Towerhobbies. Its not good for anything but a trainer but if it gets you hooked and you come back and buy a 9 channel PCM radio a year down the road, it did its job. You buy it, use it and get hooked then advance from there. Design 2: Modular I thought about the universal, expandable, modular, stupendous diversity receiver last year. Its actually not to bad at all once you approach it from the right angle. I would love to make a unit that can take up to 4 units and another that could even take 8!! Impossible? Nah. Design 3: OSD -What all could we show on our video display with a quick, off the shelf OSD module? Shoot some GPS telemetry back down, always good. Which receiver is active and signal strengths of each receiver? Heck, there is all kinds of stuff there. Design 4: Any channel, anytime. -Found a 2.4ghz module that I can change the channel on anywhere between 2400 and 2480 mhz in 1 mhz steps. Therefore it would be a universal 2.4 video module, forget frequency set 1 & 2 & 20. It would do them all! ----- I'll start with the super duper cheap model. My original design had a ton of hand building in it and after I sold it to Bill at BWAV and he took his cut the unit ended up costing a lot more then I wished it had. These new units should be super fast to build by hand especially with someone to CNC the cases for me. Next will be the modular. My big question is what frills and thrills do we really need? -Signal strength meter? (Overkill in my book, no plans for one on cheapy) -Active receiver LED (absolutely) -Channel indicator LEDs (maybe, maybe not. Depends on what switch I use for LEDs) -Speaker that chirps on receiver switch (maybe, it doesn't cost much) -Voltage range (theoretically the unit could run on 6 volts since everything inside is 5V. Definitly needs reverse polarity protection) -Screw mount (I had a tripod mounting screw in bottom of my first units, think it would be handy? Or are most people putting these things on the ground) We'll go from there, a production ready unit won't take long. The cases will be hand drilled for the first couple weeks until my CNC guy gets his stuff setup. Matt Klarich Klarich Electronics

  13. How far are you trying to receive video from??? A dish has a super narrow beamwidth on it. If the target is moving you WILL NOT be able to keep it pointed at it. There are better solutions to long range video receiving that do not require you keeping the dish within 1/2" horizontal/vertically aligned. Matt

    Diversity

    Sure looks like it too me, personally knowing pretty much exactly what is going into one of these units that price is kinda steep. Just MHO. MK

    Boris, I knew what you meant. You read my mind as to what "amazingly flexible" is... Multiple bands, 900 & 2.4. Shhhh, don't tell anyone. Matt Klarich
