  1. Funny you should say that ! I have done some more on a sunny day and all seemed ok. Played back on the A1 and PC MP10 no bother. When I came to import the video into Movie Maker MM said the file could not be imported as it had not been indexed ( I think this may be my fault as I renamed the file while it was still in the PVR H: drive)) I had to down load MS encoder and that allowed me to import the file. trouble was it had made it jerky and pixelated in places, especially around the prop strobing Perhaps I should have just transferred the file to my PC then renamed it. Our aim is t
  2. Well Here it is at long last - The first decentish video from a model aeroplane that I have been able to acieve to date. It is a big file at 34Meg but if your connection can handle it it can be found at: http://www.alanmorgandesigns.co.uk/video/tigermoth.wmv The camera is a bullet type helmet cam from rf concepts sporting 480 TVL powered by a 4.8 nicad via a dc dc converter ( Thanks Mr RC Cam) The recoring is done on board by a Mustek PVR A1 strapped to the centre section The ant you can see in the pilot space is for a 2.4 GHZ down link but it is not in use. 2 video seque
  3. The dvd authoring program I am using is Arcsofts showbiz 2 (came bundled with the DVDwriter) I am editing first in movie maker then exporting to showbiz 2 not sure I understand about impedence but it seems that my setup works ok
  4. Group leader is also looking for a pair they seem to be going for silly money at the moment £280!!!!! Dont forget if you are going to bid make sure you check if they are PAL we have been looking at UK Ebay perhaps there are more world wide
  5. I think I know why the Y lead works Just by a complete fluke my TX video in impedence is 75ohms so is the camera's lucky eh
  6. I'm not quite why it works either but it does. now I can view what the camera sees and when there's dropout I don't care because I know I'm not recording the rubbish. With the raw footage from the A1 , What would you consider to be the best format (codec?) to save it as after Movie Maker? I am writing to DVD so size is not going to be a problem, I won't need compression
  7. Soory got that wrong KILRAH tells me in an earlier post that the PVR A1 records in 320 x 240 but it still looks ok when I burn it to dvd then play it on my 32" plasma
  8. Not quite sure of the record res but I am reliably informed that it is 640 x 480 in SP mode and less in LP mode your setup seems ideal

  11.

  17. As you can see with my stuff wieght is not really a problem
  18. Hi Philthyy thanks for getting back to me. I "guestimated " that my setup was running at 1.16 so many folk have said that is the most likely so I made a patch ant scaling the 2.4 gHz one to suit I found an F connector and soldered this to the reflector with a piece of copper wire suitable for the F socket soldered directly to the element This gave me about twice the range as before. Then I had a brainwave! I remember reading (maybe Here) that the optimum length for the TX whip is 65mm Mine was 110 so I did a ground test with a pal watching the monitor I walked away with the Tx. my
  19. Hi Guys been reading loads about the requirement of a ham licence to operate 2.4GHz TX's that trasmit more than 10mw Can anyone advise me what level of licence I would need to operate say 200mw and how I would go about obtaining one??
