Parker_Woodruff Posted January 16, 2013 Report Posted January 16, 2013 I'm glad Garmin is continuing to update this product line, but am bit disappointed to see that Garmin's new Nav/Comm products only come equipped with a 2 place intercom. It sure would be nice to ditch the factory David Clark that's in my plane, but I need a 4-place system. http://www.avweb.com/avwebflash/news/Garmin_Rolls_Out_New_Navcomms_208010-1.html Would sure be a nice unit to place below the Avidyne IFD440 I've preordered... But it looks like Avidyne might win my Audio Panel / Intercom $$ if I elect to purchase that in the next couple years. http://www.avidyne.com/products/amx240/index.asp Quote
co2bruce Posted January 16, 2013 Report Posted January 16, 2013 Parker Im on that IFD 440 list also. Can't wait. I was thinking the same thing on the Nav-Com to replace the KX 155A. Quote
dcrogers11 Posted January 17, 2013 Report Posted January 17, 2013 I'll be replacing my Bendix/King 155 and 97 radios with a 430w and the GNC nav only. Any estimates on the transmitting distance on the 10 watt versus the 16 watt and any other advantages to the 16 watt. I'm curious of the improvement in transmitting distance over my 155 which I think might be 5 watts, but I could be wrong. Quote

I'm curious of the improvement in transmitting distance over my 155 which I think might be 5 watts, but I could be wrong. I have the 650 with a 10W transmitter and I am willing to bet is close to a 2/3 improvement over my 5W radio. I did check out the 16W, but the quotes were really high.... Quote
N601RX Posted January 17, 2013 Report Posted January 17, 2013 I found a 16 watt radio KY196A off ebay a few weeks ago, but have not got a chance to install it yet. The KY196's are 16 watts and available at very reasonable prices ($300). The only downside is they are 28 volts and the voltage converter is required. I was able to find a lone star voltage converter for $200. These are very small units and only weigh 1/2 lb. Quote
Piloto Posted January 17, 2013 Report Posted January 17, 2013 I'll be replacing my Bendix/King 155 and 97 radios with a 430w and the GNC nav only. Any estimates on the transmitting distance on the 10 watt versus the 16 watt and any other advantages to the 16 watt. I'm curious of the improvement in transmitting distance over my 155 which I think might be 5 watts, but I could be wrong. Going by the path loss equation the increase in range is 26% or 2dB gain for 10W to 16W. However from 5W to 16W the range increase is 80% or 5dB. Both assume line of sight range. My G530 puts out 20W which doubles the range of my previous KX 197. Where power is important is when flying oceanic where you want to make sure you are heard at least 200nm from shore above FL150. Another advantage I found is that you do not get blocked easily by other planes calling ATC during high traffic activity. José Quote
1964-M20E Posted January 18, 2013 Report Posted January 18, 2013 I like that Garmin has a new NAV/COM and Garmin makes good products but once again Garmin is $hitn on their customer base. I'm sure Garmin could have easily made the new NAV/COM a direct slide in replacement for the SL30 and SL40 they chose not to. No panel changes no wiring changes simple fast efficient installation for those who already own an SL30 or SL40. Garmin you fail again. Quote
