It showed at 820m Hans... :-)

I see another is floating in the air waves this am. Vern

I have a question with regards to the pin header connection for the U3S unit. If one wanted to have a single band unit in a small case can the LPF board be mounted outside the case and connected with

Hans I see from your pix that the GPS pins are a couple of inches away from the back panel of the aluminum case. Will the final case have a slot or something machined out of the back panel for the 4 w

With darkness approaching the Captains of the Balloons are pumping the signals out. It's a nive view!! Vernon

I have 3 balloons being heard here this afternoon on 20m. Going to need an air traffic controller soon. It's a balloon Hat Trick!! Vern KCL on 0 minute UAL on 6 minute OCL on 2 minute Good job Dave! V

John did you turn beacon mode on in the menu. Vernon

Hi all, I have a QLG1 unit that for some reason has stopped working properly. It will find the Sat's and appears to lock but no heart beat and no pps light. Also when it is supposed to calibrate the s

This morning I am hearing both of Dave's balloons with VE3KCL being over 5500km away well into EU. Also VA3UAL is about 1500km away and able to see the little balloon glyph.. Great job Dave and Hans!!

I have been using the 5 watt PA for a couple of years. Have built 3 and blew up one :-) I have never wanted to mount the amp inside the case for the simple fact that because the amp is not broad-bande

Thanks Matt...they look very much like the ones I got off of Ebay and had a +/- 10,000 cycle life. They failed well before that LOL! It's no big deal to change them but some do not last very long. Ver

Did you put it in beacon mode

Using a Wellbrook ALA100LN for everything and it hears very well. Loop is 35' long and height is around 9'. I am in a very quiet area as well. Vernon - VE1VDM

Nik I am not sure why you would need to do that. All you have to do is change the reference frequency in the menu to close to where it should be. You do that by finding out where the U3S is actually t

Thanks to everyone for their input. I did get one of them going last night. I retouched the connections for the 10 ohm mod and it sprang to life. The other one is one that I built back in 2017 that ne

I just got one going. I touched up all the pads with the iron and I think I had a cold joint where the 10 ohm resistor connects to the IRF510 pad on that mod. It started working. The other one is beyo

Resend with correction I have 3 of the 5 watt PA units and are of simple build. For the life of me I can only get one to work. There are 5 #105 capacitors, one 3.3k resistor, one 78L05 100ma voltage r

Yes…typo on my part …stressed out!! LOL!! Thanks for the correction Paul. Vernon
