Hi Moshe,

You don't even have to edit the file manually to add the frequency data in the right field. Just upload it to my website at http://www.soaringdata.info and it will fill in all the radio frequencies for you, using current FAA data. It will also update any other info, like runway dimensions.

Thanks Lynn. Does it match them up by the airport ID? Note that the IDs of some small airstrips around here have changed in recent years, so an old turnpoints file may not match all of them up. OTOH such small airstrips don't generally have their own frequencies different from the default. Also your website function will add the airports with new IDs as if they are missing in the original?
