Hi Zack, For GPSL EOSS will be flying one balloon (EOSS-252) with two beacons. The first is AE0SS-12 and it will be transmitting an APRS beacon on 144.34 MHz. The second is KE0BMV-11 and it will

​For NSTAR, N9XTN-11 will be on 144.34 MHz with APRS and N9XTN-12 will be on 144.39 MHz with APRS. At present I'm not planning any other RF payloads. I think we're agreeing that 144.39 beacons will

Hello Gang, This past weekend PHAB-16 flew (Plano TX crew) in the North Texas area. At the "after feed" we were discussing upcoming launches, particularly how we'd like to fly something on the same

SpaceX just stuck their landing of a first stage booster that's been launched a second time. It makes me want to engineer a way to refly weather balloons. I think two rolls of duct tape should be

My trackers use 2200 mAh rechargeable LiPos. These are the RC car batteries you find at hobby shops. That reminds me, I need to purchase another one. I accidentally over discharged one by forgetting

Actually I've been using the Eveready L91 AA lithium batteries for most regular flights...they are pretty good capacity and can handle the cold temperatures. But they still do make the big honking mil
