Hi I use an ICOM A-23. It is virtually useless from inside the cockpit unless I connect it to my external antenna. Folks warned me that this would be true, but, I did not believe them and had to try it for myself. They were right. Waxing poetic..... Everyone said the job could not be done Everyone said that they KNEW it. But, I TOOK the job they said could not be done. And I SURE ENOUGH COULD NOT DO IT!

A very big extra Thank You to Wayne Woollard, who is kindly sending me a known-to-be-working Cessna 300-series radio to slide in and see if the old one is simply dying. And to Glen, who tracked it down for me. Also to Hartmut, who flat-out said not to waste money on new mag noise filters, because those could not affect transmission, only reception. I also appreciate everyone's ideas for what-else-to-check-until-the-doctor-gets-there. Also in case I swap out radios and the problem is still there. A few follow-up questions: 1. Do I understand correctly from the posts that the Cessna 300-series radios (both mine & Wayne's that's on the way) are not 760 channels and therefore not regs-compliant? If some are, and some aren't, how do I tell by looking at it, whether one is? (I did say I'm ignorant of electronics...) 2. Do all the Cessna 300-series fit in the same tray? Can I just slide Wayne's in and expect it to work? Or might I have to do something else to it? 3. I tried Google-ing the Cessna 300-series to see what its transmission watts are, but couldn't find that info among the flood of ads for 300-series replacements. Does anyone know off-hand? 4. Until Wayne's gets here, my back-up radio is an ICOM A-23 handheld model, with (I think) 5 watts transmission power, and a headset adapter. Should that be sufficient for communicating in city flying (L.A. area)? Some people have said this needs to be wired into the airplane's antenna, but others have said not to do that. I would rather not, unless it's required to get adequate transmission. Do our list experts have a consensus on this issue? 5. I started to Google some of the modern replacement radio models that have been mentioned in your posts, but find the ads don't always state how many watts transmitting power, and my CFI said that is important. Is there any kind of a chart to which anyone can direct me that does a direct compare-contrast among these replacement models (kind of like Consumer Reports would do)? 6. My CFI has been encouraging me to go for 10 watts. Is 10 watts what you all would advise? Or is that overkill? (But then, he also wanted me to buy the ~$8000 Garmin stack, "because it's soooo cool!" However, I'm more a simple-analog-type, not into getting elaborate & expensive electronics just for their own sake or being "cool." ) 7. In considering a replacement radio, do I need to find out what voltage my plane's electrical system produces? I see some ads say 12-volt, some 14, some more. Can this be tested from the cigarette lighter? Thanks again for helping, gentlemen!
