Newer versions will have the ability to manually vary the power via a small Sun, 15 Nov 2009 06:40:42 GMT Yono http://groups.yahoo.com/group/bigredbee/message/244 http://groups.yahoo.com/group/bigredbee/message/244 On Profile 2, use WIDE2-1, so you only hit a few wide digis, and not the many house/fill-in digis. Or, NO PATH at all. I ran several flights on HA balloons Sun, 15 Nov 2009 06:17:56 GMT NStich@... http://groups.yahoo.com/group/bigredbee/message/243 http://groups.yahoo.com/group/bigredbee/message/243 Greg, That would be great and I agree that Path is the one element that would have the largest impact and it only makes sense to trigger by altitude. But Sun, 15 Nov 2009 05:43:37 GMT GregC http://groups.yahoo.com/group/bigredbee/message/242 http://groups.yahoo.com/group/bigredbee/message/242 Hey all you high altitude balloon guys: I'm considering adding some profile switching features to the 2M BLGPS firmware, and am looking for some guidance on Fri, 13 Nov 2009 00:25:06 GMT powellite52 http://groups.yahoo.com/group/bigredbee/message/241 http://groups.yahoo.com/group/bigredbee/message/241 Thanks to you and Greg for the rapid response. I'll try your suggestions this evening/weekend and see how it the BRD responds. I'll take you up on your offer Thu, 12 Nov 2009 23:34:32 GMT NStich@... http://groups.yahoo.com/group/bigredbee/message/240 http://groups.yahoo.com/group/bigredbee/message/240 Dan, I use mine for high altitude balloons and I have mine set to beacon at every 15 seconds. I also use the alternate APRS Freq of 144.99 which in my area is Thu, 12 Nov 2009 23:21:21 GMT Greg Clark http://groups.yahoo.com/group/bigredbee/message/239 http://groups.yahoo.com/group/bigredbee/message/239 set the "slow speed" and "fast speed" to the same number, say 100, then set the "slow rate" and "fast rate" to 30. Now it will transmit every 30 seconds (make Thu, 12 Nov 2009 23:09:53 GMT powellite52 http://groups.yahoo.com/group/bigredbee/message/238 http://groups.yahoo.com/group/bigredbee/message/238 Hello; I'm planning on installing the BRB 2m GPS unit in a near space balloon and I'm having some problems understanding in how to force it to beacon every Thu, 12 Nov 2009 14:58:24 GMT Greg Clark http://groups.yahoo.com/group/bigredbee/message/237 http://groups.yahoo.com/group/bigredbee/message/237 Fiberglass shouldn't have any measurable impact. You want to avoid carbon fiber and metallic paint. -- Greg Thu, 12 Nov 2009 14:31:36 GMT rmilliken http://groups.yahoo.com/group/bigredbee/message/236 http://groups.yahoo.com/group/bigredbee/message/236 Opps, guess that would help. Most of the ones I'm concerned about are fiberglass over foam or cardboard tubing.

Thu, 12 Nov 2009 03:47:01 GMT powellite52 http://groups.yahoo.com/group/bigredbee/message/233 http://groups.yahoo.com/group/bigredbee/message/233 Thanks Greg; I'll drop it into the US mail in a day or two along with a check for the $5 so you can update it. I don't have a pic programmer at this time. Thu, 12 Nov 2009 02:00:16 GMT Greg Clark http://groups.yahoo.com/group/bigredbee/message/232 http://groups.yahoo.com/group/bigredbee/message/232 Hi Dan, Unfortunately, this model of the PIC doesn't support firmware updates via a "bootloader" like the BigRedBee GPS does. You can send it back to me along
