range testing Cirrus MRX-4
I decided to give ony of these little receivers a try in my mini-max (for less than 20 bucks, what the heck?). I wound about 10 inches of antenna around the included antenna bob, or whatever its called. I know that the receiver supposedly has a 1000 foot range, which should be more than enough, but I'm concerened how it will perform with the antenna wound. What's the best way to range test these single conversion receivers, and what kind of performance should I expect (for example, with the transmitter antenna down)?
Thanks, Rick |

Range test just like any other radio system. Collapse antenna and walk away. I'd say 30 - 40 feet would be sufficient with the antenna collapsed.
When you wind the antenna around the bobbin, just be careful that it doesn't cross over itself or the range will be cut drastically. Honestly, I'd forget the bobbin and let the antenna hang out the back. I have a Hitec 3 channel am rx in my mini max and the antenna just hangs out. -Todd |

Okay so far.
Mine passes the standard range test at the field (Where there is loads of RFI), but have not (yet) been able to fly it up to a 1000 feet due to the high wind.
My FMA Razor is just too light for the 15 to 25 MPH winds we've had here in the Northeast for the last week or so. Rich<> Update: 10/12/02 Flew the Razor out (and up) to about 600 feet today. No problems at all. Hope it works as well when 3 other pilots are flying on nearby channels.. |
