I keep having to ask you questions. Well I appreciate your help anyway. So we are trying to shift over to hydrogen and the local welding supply place wants $500 for a regulator. Yet I see this $93 dol

Joe, please tell us more. Latex or other envelope? How did it work out for you? Any special reason for trying this valve method out? What altitude was reached? How long did it remain in the air? _____

Looking at the cross section dimensioned drawing and the photograph, it's pretty certain the tetroon was filled through an internally threaded port. After removing the fill tube from the port, the cal

Hi Doesn't look like VA5BNC-15 is going make another miraculous recovery today. Not surprising as the surface winds at touch down were in the 30 km/h range. Looks like the nearest APRS stations are 40

Wow....It took off again !! It Must've needed to get some sleep last night :-) I will alert the potential GA recovery folks to regroup. - Bill WB8ELK -----Original Message----- From: Bruce Coates <bru

Nice signal on VA5BNC-15 from 200 miles distance as it flies towards me. Copying it direct on 144.390 MHz and i-Gating it here. I also see K7HAK-11 in the waterfall at 300 miles distance but too weak
