Thanks Brian....005” is not easy to find, but I like the overall weight !! FYI...we just made our first lap around the globe today with a WB4ELK APRS tracker and SBS-13. Using call sign WB0URW-8.... 7

Mike, I’ve been using .005” music wire (not stainless steel) for the 20m dipoles. As for the 2m we usually use a .009” guitar string but on the -W flights used a insulated wire from a Cat-5 cable so t

Not sure if this is the right group for this, so if not let me know: I am getting a LightAprs-W tracker ready to fly this winter. Just wondering if anyone has flown this 2meter/20 meter machine with b

Problem solved! Thanks to everyone and Mustafa. I have already tried other cables, yes that is also good advice. The root cause was too many libraries getting their shoelaces tied together and then fa

Looks like your device may not have a bootloader installed. Try using "old bootloader" to see if that works. _._

Hi Leon, Try to upload the sketch file with another usb cable or another pc if possible. If you still get this error contact support@... TA2MUN

So here's the thing: I have programmed Arduinos before, but the lightAPRS fails to program. I'm stuck. In Windows Device Manager it correctly picks up Com21 as the USB port and I've set the various pa

James, the only misgiving I have with the pic implementation is that you are relying on this little pic to not get into a brownout itself. Using resistors, diodes, and opamps, and perhaps flip-flops i

#Balloon #lightaprs

James, I don't have the tracker, so I'll have to rely on what you know of it's settings. I can try to read through the manual, but others here with specific experience would probably be a better resou

Shane, Looks like we were replying at the same time. Option 1 sounds very feasible. I have some super low power PIC's that should be able to do just this. To make sure I understand your suggestion: Im

One more question --- The recommended setting for BOD is 2.7v. Since the code is set to stop doing anything once it gets below 4v anyway, suppose I set the BOD to 4.3 and raise the GPSMinVolt to just

James, I don't know what your electronics experience is, but if you are a designer, you can hit this issue a couple of ways- 1) implement a watchdog timer that looks at a periodic signal from the proc

Thanks Shane. I was considering just what you suggested. I've looked at a lot of other people's balloons and saw that many of them last tracked in a similar situation. Makes me wonder if a lot of peop

#Balloon #lightaprs

James, just a thought here- I know it's probably too late for this to help your current situation, but for future projects, you might consider putting in a voltage monitor that can fully turn off the

All, Has anyone experienced trouble with the aprs-w not waking up once fully charged? I've noticed that the wakeup on solar has been a little fiddly. Yesterday morning I prepared to launch my balloon

John, Here is a breakdown of the data fields: 012TxC This is the number of transmissions the tracker has attempted since it last powered up. In this case it sent out 12 packets today but they may or m

Hi, We launched two balloons this morning from Rosamond, CA USA. Both had been tested multiple times on the ground before launch. The first was a SBS balloon and a LightAPRS-W transmitter. APRS call i
