[Moon] [Moon-Net] SMALL PRIME FOCUS DISH

[serge]

Hello Pierre- Francois & all. A very interesting thread. I certainly have learned a lot. I was truly fascinated by Hans PA0EHG demonstration at EME 2014 & also the work of Rex VK7MO so I want to try it.BTW there is a new IOPTRON gear box 8200 which has all the gears made of metal & not plastic like the one Hans has. It is also more expensive. The question is how much abuse it will take. I will be looking for an offset 1 m dish & discuss the tracking settings of the ioptron gear box with Hans.Peter OZ1LPR has done very well with his 1.8M dish & low power
I think the big issue with 10ghz is TRACKING & frequency stability that is what I read anyway
Thank you again
Serge VE1KG

  Hi Serge & the Gang,



  Glad to hear I'm not an alone crazy guy thinking seriously to build a system with a telescope mount following the marvellous presentation from Hans at EME2014.
  From my side I'll use a bigger dish and probably will invest into a much strongger mount than the Ioptron one. The investment will be significantly higher but it'll be there for the rest of my life... 

  We have never seen a safe cabinet to follow an hearse... Lol...

  Don't know yet which dish I'll use, I've got a plain 2m one but may be too heavy, I need to weight it, if not adequate probably a 1.9m mesh one (2.8mm mesh) from RFHamdesign with a multi-band source, will see.
  I checked this morning on their website, this 1.9m dish is only 7.6kg plus the source, so not too heavy for a solid telescope mount.

  And I'll use the transverters as the counterweights (patented idea... Lol...) so it'll not be part of the payload. 

  Any other ideas will be apreciated.


  Best 73's

  Hello Friends
  I am looking for a source of SMALL prime focus dish from 75CM  to 1M for 10ghz. I will be using the Iptron gear box which Hans PA0EHG used at EME 2014 in France. I probably could use an offset dish but because of the nature of the Ioptron gear box it suddenly becomes more complicated because of the offset.
  Your help will be appreciated
  73, Serge VE1KG
