I don't know of any other online services like that that don't use Google Maps API in some form or another. 73 de Mark N9XTN

Is there an alternative to aprs.fi? I was counting on aprs.fi for our planned HAB flights in OK. Jason KF5UEF

This is a copy of a message posted recently to the APRSSIG e-mail list. Google has implemented a new pricing structure for Google Maps that are negatively affecting services like aprs.fi. The

I also want to thank everyone who has helped to make this conference the success it has been.

We have commitments for GPSL until 2023. Amazing how this is conference is still goong strong after 17 years. Here's the breakdown. 2019: PENS in Pella, IA 2020: NSTAR in Omaha, NE 2021: Bill Brown in

I know this is a tad late but maybe you might have something in your collective junk boxes.   When I first read this it might be suitable for a small signal source oscillator keyed or switched on

Hi Kip Yup. The idea of it providing a method for coupling to a ground plane certainly seems to be the most plausible purpose. 73, Bruce

I can not put my hands on it right now, but a GPS antenna specification i read last year, recommended the antenna be mounted on a minimum of 40mm x 40mm ground plane to get maximum GPS sensitivity.

Right. Missed that part. Yes, the entire "back" side of the mesh is covered with adhesive. I think that's what holds it to the shield as there no evidence of any soldering or other electrical

Yes, it's definitely electrically connected to the coax braid. They're stripped the outer insulation for the entire width of the mesh and wrapped the mesh tab around it. Oddly, either the

The decoupling idea did occur to me, but I did kind of slide over your wording concerning the coax shield. A few more clue requests: By "connected," do you really mean connected galvanically to the

Hi Hank Interesting. I was also wondering about it being some attempt at common mode decoupling, like a 1/4 wave stub. 73, Bruce

Bruce, I'm pretty sure that's a ground plane intended to be affixed to the underside of the supplied antenna to improve its performance. One of the clues is the presence of the adhesive; another is

Hi I'm building a tracker using a Ublox Neo 6m module from eBay (of course). My module has an adhesive "thing" on the feedline about half way down. This "thing" is fine metal mesh and is connected to

To add to Mark's request... If you find yourself in the Valentine area of Nebraska around August 9th, we could always use your help chasing after two balloons. Thanks

Hi Mark It's probably not feasible given the time frame but I'm working on an Arduino (Trackuino) based tracker for a floater. It's definitely a DIY project as it's assembled from

Paul KD4STH and I are looking at doing a launch from the Nebraska Star Party on August 7 from south of Valentine, NE. The region is fairly devoid of roads, and much more populated with cattle and

My items are mounted two feet from the camera on an acrylic plastic platform. Two carbon fiber rods hold the platform in place. The carbon rods are bolted to the bottom of the airframe using plastic

For those of you who have flown promotional items in the foreground of your cameras, do you have any tips or suggestions? I have a cut-out cardboard figure to fly into space, and am just wondering

It will be Sunday the 2nd. I will contact Strato Fox for help.
