    Fellow Kolbers: Our own Richard Pike is in the Short Final section of AVWebFlash this morning. If you have not yet read it, here it is: SHORT FINAL I was a controller at Albany Georgia tower back in the '70s, and a Cherokee was on downwind, with the instructor introducing his student to radio procedures. Fortunately for me, their intercom locked on for a bit and I got all the dialog between the student and the instructor. It went like this: instructor: "Say 'Albany tower.'" student pilot: "Ah Al-Albany tower?" instructor: "'This is Cherokee 76 Whiskey.'" student: "This is is Ch-Cherokee ?" instructor: "'76 Whiskey.'" student: "Seven 76 Whiskey?" instructor: "'We are on left downwind for runway 22, touch and go.'" student: "We are on ?" instructor: "... 'Left downwind for 22.'" student: "Left down-downwind " instructor: "... 'Downwind for 22, touch and go.'" student: "I don't want to learn to fly no more!"

    Subject: Radio Check =?ISO-8859-1?Q?=93?= Learning
    From: "miyer2u" <miyer2u@yahoo.com>
    Dear Kolbers, I wanted to share with you a learning that I had and may help some of you! I have an external whip antenna on my FS-2 and have a Handheld Icom A 22 connected to it. I had a long cable 2.50 meter (RG-58) running from the radio to the external antenna which should be in multiples of (Half wavelength - 1.25 meters or 2.50 meters) for 121 MHZ center frequency that we use. Since the length was too long, I reduced it to 1.25 meters (4.1 feet) and had to install a new RF BNC Connector to connect to the Radio. The new connector was a screw in type that gets into the Coax cable and after installing, I picked up some local frequencies and assumed alls right! I had been receiving all frequencies so was flying around with this set up for a couple of months. Last Friday I picked up a signal from a Bonanza who was also entering the pattern and tried communicating with him, but it was one way, I could hear him, but not transmit. After I landed I did a continuity check and found that that the screw in connector did not connect well. I went ahead a purchased a factory molded BNC connector from Radio Shack and that solved the problem. My learning was that it is always good and necessary to do a radio check before one takes off to ensure two way transmission. I have added one more R to my CIGARRS checklist- CONTROLS-INSTRUMENTS-GAS-ATTITUDE- RPM- RADIO CHECK-SAFETY.

I am just curious,,, where did you get your information???? boyd young ham radio extra class N7WFM kolb mkiii n1225y

    From: "Tom O'Hara" <tohara@alphagraphics.com>
    I had one years ago. It was at a hot air race with 75 balloons. Pre-race documentation warned or is it informed that FAA would be doing ramp checks. On the first flight I was pre-flighting and got a tap on the shoulder. Pulled out the Arow docs. Well, weight is interesting in a balloon-- now I am heavy, three seconds of heat and now I am light. He had no problem. I had an extra spot in the basket so I took him for his first hot air flight-- figure I saved another pilot from getting a ramp check--LOL Read this topic online here: http://forums.matronics.com/viewtopic.php?p=338085#338085

    Hi Boyd, May be you are right when you say that a tuned antenna will not require the magic figure of 1.25 or 2.50 meters. I have not tried if it does make a difference. I referred to a very good article posted by Bob Kirby - Radio Installations in Ultralights and Homebuilts (Google it) I had been facing radio problems for quite some and have slowly got improved results. Some of the changes that helped are as follows: 1.Shielding all cables, especially the Kill switch and Hobbs meter 2.Moving to resistor sparkplugs 3.Installing a external whip antenna with a ground plane 4.Connecting the whip antenna to the radio using a RG 58 coax cable. I am still not done as I have to shield the sparkplug cables. With the current set up, I can hear and transmit clearly until I reach 5900 RPM, but between 5900 RPM and 6400 RPM, its still worse, so the improvement continues. I believe Radio Installation is an art and a science!

    I believe Radio Installation is an art and a science! Thanks, Mahesh Mahesh/Gang: I'm with you, my friend. However, there are a couple things you can do that will improve your radio performance in your Kolb. You already mentioned resistor plugs which help a lot, but what helped me even more was a capacitor. On my 447 I used a 10,000 or 15,000 mfd. I imagine the big ones we use on 912 engines would work as well. They are 22,000 or 25,000 mfd. You all correct me if I am wrong. I am pulling this out of my worn out memory. These two items were the primary fixes for me. Other things may have helped a little, but not enough to brag about. john h, who flew five days last week. Beginning to get the hang of it again. ;-) mkIII hauck's holler, alabama

    A 22,000 microfarad electrolytic capacitor rated at 18 volts should be considered a minimum. Connects right where the battery would go. A 47,000 mfd. cap. is even better. You can do a google search for "electrolytic capacitors" and find lots. No need to spend more than $15. In a message dated 4/25/2011 6:16:16 P.M.

    to all interested parties. ok radio installations is 1/3 art 1/3 science &1/3 magic..... I say this a bit tong in cheek... some antenna's defy all logic leave you scratching your head, and you are left wondering WHY or WHYNOT,,, now for clarification,,, the capacitor should be between the voltage regulator and the battery, if it is an electrolytic capacitor, make sure it is installed in the correct polarity, you could also use one on the power buss for the plane, one other thing that can help is a set of inductors,,, if you wind a wire around a ferrite ring, and install one on the positive, and one on the negative side of an appliance, it can greatly reduce rf or pulsed dc energy from getting to your devices. inductors used in conjunction with capasitors make a good filter. I have a gprs tracker in my plane,,, it started out causing interference to my radio, as well as the EIS. the inductors and a capacitor completely eliminated the interference, if you are running the radio with batteries, they should not be needed, but if you are running off the aircraft power I would find or make some. the ones I used came out of an surplus computer hardware, all mounted on a circuit board. capacitors and inductors do kind of the same thing,,, but they do it differently. their differences is part of the reason they work so well together. if anyone wants a better description let me know and I will give it a go. boyd young mkiii utah >>>>>>>>>>>>>>>>>>>>>>>>>>>>> I believe Radio Installation is an art and a science!
