Is there an easy way to modify the Pico to work on higher bands? 30 meters doesn't seem useful at this time in the sunspot cycle. 20 meters will always be open before the sun is high enough to power the radio. I can't imagine a situation where the pico goes all day without being heard on 20, but does get heard on 30. 20 meters combined with a higher band might be a more useful combination. 20 would continue to do most of the work. A higher band would have a longer skip distance for those occasions when a balloon is over Kazakhstan and no-one is in range on 20. I would do a mod if it is easy. Better yet, future versions of the Pico could offer high bands. Thanks, Dwight KO6FE

Hi Harry, I'm getting ready for a balloon launch using a Pico tracker I bought from you last year. I not able to activate the "more precise location". I updated the firmware using the download form your website. Now we have version 1.0 installed, but still can't get the precise location to function. Is there a more recent firmware to install? Or, maybe I'm doing something wrong? I know very little about Arduino. Dwight KO6FE
