What angle to the horizon are your solar cells tilted? 73, Willie N1JBJ

The problem that my balloon has, is I used power film solar cells. When mounting my 6 glass 0.5 volt cells I broke 2 of them. Trying to beat the weather I went with 4, 3 volt power film cells in paral

I think John, that at this time of year, just past the northern Summer solstice, the far north is far from dark. North of Iceland it never gets dark at this time of year. Regards G0BZB

Great to see that the KG5TED Balloon is back on the air @ .010w over Asia. Must have been in the cold/dark North for a few days. Looking good Ted, great first effort and testament to the resilience of

My first attempt at a QFH was 1.9g without making any effort to be light. I made a few jigs to help get the shape correct but in the end the dipole worked better than my attempt. I was hoping the circ

Wow, that antenna looks quite heavy. I am not sure you are going to benefit from the design if you cannot lift it. The goal of a pico balloon is to fly as high as possible given the balloon type and o

Thanks for the tip Dave. I'll use that next time I have difficulty tinning enamel-coated wire. I tried this wire using both liquid and solid flux and I still couldn't get it to penetrate a 400C solder

#Balloon #antennas #u4b

Alan In the case of a restrictive ball of solder put some paste flux on the thin wire first and freshen up the ball of solder on the tip of your iron with some new flux cored solder ... you only have

#Balloon #antennas #u4b

I did try the "Insert the wire into hot solder" method of tinning, but the wire is just so fine I can't get it to go into the solder! It just bends at the surface of the solder. I also tried trapping

For cement, how about a light coat of Polyeurethane from a spray can? Lightest application possible.... Ted K3RTA

Hi Alan don't try and sand fine wire just stick it into a blob of 340c solder till it is tinned Dave VE3KCL

In playing with the float altitude, I am going to have to add some ballast with a 32” balloon. I had to make a strain relief for the dipole but the .011 enameled wire I am using is working well. The G

Well, I'm calling my 0.002 Inch diameter (44 guage)+ Dyneema fishing line antenna a failure and moving on to bigger wire. I got everything stretched out on the floor, got the wire cemented to the line

After changing the sign back to baloon /O, no more errors, but still nothing to see on the map. No TX, about 50mA consumption... Any hints? Running out of ideas. 73s Ingo Am 2022-01-24 17:05, schrieb
