Transmit power is unlikely to be a problem.
Difficulties are more likely to be seen in the receiver performance - in particular the receiver selectivity or the ability to reject out of band rf energy. Typical interference will be from radar sites, cell towers, hf transmission stations etc, and if the security services are in town the spectrum spreading tranceivers. (this is certainly the case for my own handheld) Effects will be noise or deafness of the receiver. The small packages of the handheld are often not sufficient to house the filtering necessary - but the modern micro devices are making better receivers smaller. Also, check to see that the handhleld will work with your headset if you plan a direct connection. Microphone powering For electret mic inserts is sometimes not sufficiently versatile to work wth some headsets. Doug Gray |
We do this all the time in Luscombes.
For range, you'll want an external antenna, and there are adapters that allow you to plug a normal headset into the handheld. Icoms seem to work the best, and you need to be aware that Vertex radios don't do well with an external antenna, due to the antenna overloading the RF sections. Vertex radios on their factory rubber duck antennas work well; albeit without the range that an external antenna provides. Main issue that I have seen with handhelds is being able to read the frequency from wherever you mount it. Sit in the plane and experiment with this attribute. |
Anyone with experice with the Dynon handheld that they'd care to share? I looking at a similar thing for an ultralight
