The best guess is that your antenna is not right or your ground plane is either non existent, or there is electrical interference.

One of the things we did was to use a handheld radio and while the engine was running, and using the handheld radio, move around the airplanes and try and discover where the engine created the most noise and the worse reception, and the least noise and the best reception. We discovered that the best place for minimum noise and best reception was at the top of the vertical fin. Based on that, we relocated the antennas for each airplane to the top of the vertical fin. Here are the pictures of the installations for both the MKIII and the FSII. The antenna is made by taking a Radio Shack twist-on male BNC connector, part # 278-103 and a length of 1/16" model airplane pushrod steel wire, and combining them like this: take one end of the steel wire, and taper it on a grinder until it will fit into the connector until the end just pokes through the end of the middle terminal connector. Solder it to the connector at that end. Fill the shank up with epoxy, and after it hardens, cut it to about 25 inches total length, and trim it to final length while checking an SWR meter. If you don't have an SWR meter, make it 24 1/4" long total length, base to tip, it will work. Put a little curl on the end, or Murphy's Law says someone will poke it through their eye. Cost? $8. Weight? 2 ounces. Another factor was the headset. I had been using a Softcom headset for a number of years, but unbeknownst to me, it had gone bad. Got a new Gulf Coast Avionics El Cheapo ANR headset and it helped immensely. Also got an older Lightspeed ANR headset, and it also improved things immensely. Both are very good and quite comfortable, and the price in both cases was very reasonable on ebay. I can call TRI ATC for a comm check and get "5X5, with some background noise." Since both airplanes have a Rotax 582 churning away in the background, that sounds reasonable, and a pretty good deal. Before getting the new headsets, TRI ATC said I was unreadable. Hope this is helpful. -------- Richard Pike Kolb MKIII N420P (420ldPoops) Kingsport, TN 3TN0 My soul shall be joyful in the LORD; It shall rejoice in His salvation.

My plane had a commercial aircraft antenna mounted just ahead of it in the nose cone without a ground plane and would not transmit more than 8 miles. Mounted and grounded to the floor pan my homemade transmits 29 miles with an icom A4 radio. It was a bit scratchy, so I installed a large capacitor (per John Hauck) and it now transmits loud and clear. The only noise that I hear in it is the quiet click of the strobes.
