Mirage T-Injector Problem
by Richard Lawn 29 Sep '15

29 Sep '15

I've finally diagnosed the problem with my new ARR preamp. I really thought it was the preamp until I got it on the bench and found that when I power the ARR preamp via the coax I see the under load the T-injector's DC output drops about 2.5 volts to about 11.15vdc. How can this be? Any suggestions on how to modify the T-injector so this doesn't happen? It strange as I've used several different Mirage injectors with their preamps and an Icom preamp with no problems but neither Mirage injector I own works with the ARR preamp. 73 Rick, W2JAZ

LilacSat-2 pass @ 0147 UTC tonight (29 September)
by Patrick STODDARD (WD9EWK/VA7EWK) 29 Sep '15

29 Sep '15

Hi! There was a nice turnout on the 0147 UTC LilacSat-2 pass over the US west coast. Stations up and down the coast, and as far east as west Texas, were on. Unlike with the first QSO I made on this satellite last week, when it was raining very hard on my operating position in the yard, I was able to have a nice and calm evening. I used my Icom IC-2820H 2m/70cm FM mobile radio for my uplink transmitter, and an SDR setup for the downlink receiver - SDRplay SDR receiver, 8-inch Windows 10 tablet with HDSDR software - to operate full-duplex. I connected both of these through a diplexer to my Elk log periodic. I used HDSDR to make an RF recording of both downlinks - the FM repeater downlink around 437.200 MHz, and the digital telemetry downlink around 437.225 MHz. I think I had a better copy on the 437.225 MHz downlink tonight than over the weekend, and logged 6 contacts on the FM repeater. Last week, when I worked Glenn AA5PK, I was not able to get through with anything less than 50W transmit power. Tonight was not as bad, but I found that I couldn't get away with 5W for more than a few transmissions. The mid-power setting from my IC-2820H, 15W, worked better. High power (50W) worked well, too. None of these power levels desensed my SDRplay receiver. Maybe if the satellite was higher in the sky, and closer to passing over my head, I might have had better luck using the 5W power level. I saw a mixed reaction on Twitter - one reported needing to run 50W, and someone else said 5W was sufficient. Rather than posting the long and nasty URLs used by Dropbox for its public folders, I made a shorter URL that can take you to the recordings and other files I have been posting in my public Dropbox space: http://dropbox.wd9ewk.net/ For tonight's LilacSat-2 pass, look for the folder with the name "20150929-LilacSat2". If you have an SDR program on your computer or device, and have the bandwidth to download the RF recording, download the WAV file with the name starting with "HDSDR_20150929" in that folder. I also have an MP3 recording with the audio I heard during the pass, plus photos of my back yard setup and a screengrab from my phone's tracking app to show how the pass was for me in central Arizona. Late last week, I made a one-page graphic with a quick-reference guide for the LilacSat-2 FM repeater. I now have this graphic at its own URL: http://lilacsat2.wd9ewk.net/ Please feel free to right-click on the graphic and save it to your computer/tablet/device. This pass was the 3rd consecutive pass where LilacSat-2's FM repeater was operational over the continental USA. It was nice to see the reports from the two earlier passes, and then to work it for myself on the third pass. Thanks to the LilacSat-2 team for another FM satellite for us! 73!

New Satellites! ? (keyhole view)...
by Robert Bruninga 29 Sep '15

29 Sep '15

Watching the BB about all these recent satellites is like watching a parade through a key hole. Would someone with the time simply make a very brief summary of these items: NAME, NUMBER, Inclination, DOWNLINK, UPLINK, MODE, comments ANd try to remember to include the table (as updated) in most emails so that we can all benefit as a group from your efforts. When new info comes along, hit REPLY, then edit the table with your new info. And for the table, KEEP it BRIEF, else we cannot see the trees in the forest. Bob, Wb4APR

Fall Grid Trip - Summary
by R.T.Liddy 29 Sep '15

29 Sep '15

This Fall's Grid Expedition took place 9/17-9/23. I had several requeststo activate some northern Grids in Ontario and Quebec. So, I mapped outa route quite a ways north of Toronto in Ontario to EN99 and over intoQuebec to FN18 and down to Montreal and over to FN24 in Upstate NY. My portable station was an ICOM 820H and an Arrow Antenna on a homebrewAX/EL/Vert/Horiz tripod mount. You can see the setup on my QRZ.com page,but it shows my Arrow prior to building the tripod which makes things much easier. The first station worked on the trip was KG5CCI while in FN05 on FO29and the last station worked was WI9I while in FN24 on SO50. Special Thanksto Frank K4FEG who was always around with helpful info and assisting withputting out status messages on the Internet on my progress. Extra Special Thanksto John K8YSE who kept me company at the end of most passes when I wasalone and there was no one left to work. John would always have a signal thatwas copyable nearly to my LOS! Here are some highlights of the Trip by the numbers:0 - The number of stations worked on an FO29 pass in FN08. Where were they?1 - Excellent & Understanding XYL who lets me do these solo trips.1 - Only once did anyone come over to me and ask what I was doing.2 - DX Countries worked. G & ZF.2 - Stations that said I was their FIRST SAT QSO!!3 - Chicken Dinners I ended up with vs.ONE in Quebec due to my poor Francais.4 - Countries worked ...plus All US Call Areas and VE2 & VE34.56 - Price per gallon in Canadian $ equating to 3.39 in US $5 - The number of cylinders I drove home on the last 150 miles, fouled plug!6 - Motel stays (Thankfully, 25% advantage using US Exchange Rate!)7 - Days on the road seeing absolutely beautiful scenery!!11 - Voltage of my truck battery the day after I got home - replaced. (Glad I was HOME.)12 - Number of Grids activated. FN05,06,07,08,18,17,16,26,24 and EN97,98,9921 - Stops for Grid Activations.73 - Number of different stations worked - 36 with single QSOs and 37 with multiple QSOs.234 - Total QSOs - 181 on FO29 and 53 on SO50.2065 - Total trip miles.++ - Lost count of the number of times I heard, "Thanks for the New Grid!" Biggest Thrill - Tie between working 2 stations as their FIRST SAT QSO and the multiple times I gave folks a New Grid!! Biggest Disappointment - The level of QRM on SO50 on every pass that prevented numerous QSOs I was trying to finish with stations. Most Interesting Roadside Marker - 'Now Entering The Arctic Watershed"!! WOW, that's what I call NORTH!!! Hope you enjoyed my trip as much as I did. Would I do it again? YOU BETCHA!! 73, Bob K8BL /VE3/VE2/W2 (AMSAT #6593 Since 1979)

Clayton, Is the downlink at 447.220 as recently reported? From earlier reports, it seemed to be around 457.200 as dome (might have Bern you) were hearing it at LOS near 447.191.
