Re: New to APRS

Go to this page <http://aprs.fi/> http://aprs.fi/ and look for APRS activity in your area, chances are you are already on the map! Take a look at the last 12 hours, you will see the path of moving vehicles. If you put the pointer on one of the dots, you will see the path the signal follows maybe crossing one or two digipeaters before arriving into the gateway to be transferred to the internet. Nothing like real data to understand how the system works! Regards, Alejandro HP1COO, yes from PANAMA

What book/manual/text would you recommend to this fictitious ham to learn more about this exciting aspect of amateur radio? Please let me know ... and I will make sure to read --- er, I mean, I'll be sure to pass on the info to this ham.

September Mini Gridexpedition
by Zachary Beougher 20 Sep '10

20 Sep '10

Hi All, First off I wanted to say thank you for all the QSOs during my mini gridexpedition to Colorado! I made 138 QSOs on 21 passes from 3 grids in Colorado and 3 in Kansas - EM08 (KS) mobile on the way out, DM78, DN70 and DN60 portable in Colorado and EM08, EM19 and EM29 mobile in Kansas on the way back. Hopefully I got some of you a couple new grids. I have already received several QSL requests, and I will respond to these as soon as I get the cards in. Unfortunately, the cards will probably not be in from UX5UO print for 4-5 weeks. I will try to send out an email when I have a better ETA. If you would like a QSL, please send your request to my address listed on QRZ.com. An SASE would also be appreciated to help defray postage costs. Operating conditions were very favorable for the most part of the trip. Interference from mountains was very minimal, and the weather was fantastic! I did not do much operating at the beginning of the trip, only the mobile operating in EM08. We arrived on Friday and spent the next couple nights at an RV resort south of Colorado Springs. On Saturday we ventured up to Pike's Peak (DM78), and I was able to operate one AO27 pass before we had to go down due to the thin air. My Mom overheard the interesting conclusions people were coming to as to what I was doing - "He is a Ham Radio operator"; "He is with the Air Force Academy"; "He is talking to the world". I thought these were pretty good. The following day (Sunday) I was able to get on from DM78 for a second time on an early morning SO50 pass. It was nice to be able to work a few of the eastern stations along with K8YSE/p who was doing a satellite demo at the Findlay hamfest. Sunday afternoon we traveled up to Estes Park in the Rocky Mountain Park and setup camp for the night at a park campground. Operating became a little more consistent over the next few days from DN70 with 13 of the 21 passes being done from this grid. On Wednesday we took a little side trip down to Grandby on the southern side of the park to do a DN60 grid activation. I really wanted to do the DN70/60 boundary, but there was no suitable place to operate along Rt. 40. We ended up driving about a mile into DN60 before taking a gravel back road (and I mean back road) up into public land in the hills in search of a higher spot to operate. Just to give you an idea of how back road-ish it was, there were cow skeletons along the road. It was true "cowboy country". Anyway, we found a spot about a mile up the road and got set up about 45 minutes before the AO27 pass at 1929z. This enabled me to get on the 1905z HO68 pass and work a few stations. Four contacts were made on HO68 with 21 on AO27. I hope that everyone that wanted this grid was able to get it. I wanted to stay longer, but we needed to get back across the mountains (which is a 2 hour trip) before dark. Operating continued from DN70 until we left on Friday. Friday evening I was able to get on AO27 from EM08, SO50 from EM19 and AO51 from EM29 (KS side). It was really fun to be able to work into the birds with a quarter wave mounted on the van roof. I could only hear between approximately 35-75 degrees which kept operating mobile short, but it was fun to make a few more QSOs using different equipment. Videos of the Pike's Peak operating and the DN60 grid activation have been uploaded to YouTube (look under KD8KSN), and to my QRZ page as well. The footage was not the best, but it gives you an idea of how high Pike's Peak is, and how remote the DN60 activation was. Pictures have also been uploaded to my QRZ page. Thanks again to everyone who supported me during this trip, and for all the contacts! I certainly hope to return to more rare grids in the future. 73! Zack KD8KSN

AO-51 Sep 19 UCT 22:59 pass recording?
by Peter Ng 20 Sep '10

20 Sep '10

Hi, I was wondering if anyone has a recording of the 22:59 UCT AO-51 pass available from yesterday? I heard someone from EM40, but did not write down his call. I was testing out the CJU downlink antenna by EA4CYQ. It was a 22 degree pass for me and was surprised by the antenna's performance. Thanks in advance! 73's Peter VE7NGP

ARRL SW Convention
by Clint Bradford 20 Sep '10

20 Sep '10

My session on working the satellites last Saturday at the ARRL Southwestern Division Convention in San Diego was attended by FIFTY-SIX folks! Standing room only - five were standing in the back of the room. We had a great time. I had to shorten my presentation a bit - because we only had 50 minutes. But I heard from attendees that it all went well. Additionally, we worked two satellite passes Saturday afternoon out on the patio. Twenty-two attended the 3:46PM pass of SO-51 ... eighteen attended the 4:31PM pass of AO-51. I was pleased that many of these folks were NOT in the morning session (I printed up signs with the times an posted 'em on the convention's cork bulletin board and had one on an easel outside the meeting rooms). So ... impromptu "Q & A" sessions were held out on the patio, and we all had a great time a we contacted Montana, Arkansas, Tijuana, San Diego, Colorado, Yellowstone National Park and more stations via the "birds."
