Nayif-1 at 0305Z
by Paul Stoetzer 15 Feb '17

15 Feb '17

Made my first QSOs on the Nayif-1 transponder on the 0305Z pass covering most of North America. I worked AC0RA in Texas, AA5PK in Texas, NP4JV in Arizona, W5PFG in Texas, and WN9Q in Wisconsin from my QTH in southwest Washington, DC. I also heard KO4MA in Florida and NR0T in Minnesota. Signals were generally strong, with some fading at points. It seems to work at least as well as AO-73's transponder. As I was operating manually, I could not precisely evaluate the frequency stability, but I had no trouble finding myself very quickly. It was much easier than finding myself on an equivalent pass of AO-73. Equipment used: 2 x Yaesu FT-817 High Sierra Microwave LNA146FIL preamp Microset VUR-30 amplifier (about 22 watts max on 70cm) Arrow II 146/437-14 Antenna (handheld) Congratulations to the Nayif-1 team on a successful launch and activation of the satellite! 73, Paul, N8HM

WD9EWK road trip around Yuma Hamfest, this weekend
by Patrick STODDARD (WD9EWK/VA7EWK) 15 Feb '17

15 Feb '17

Hi! I will head west for this weekend's Yuma Hamfest tomorrow night. Since I am not leaving earlier in the day, I don't plan on making stops along my drive from Phoenix. With that said, if I am making good time on the drive, I might stop to work a pass or two on the drive west. The best way to see what I'm doing is to look for WD9EWK-9 on APRS: http://aprs.fi/WD9EWK-9 I will spend most of my drive on the I-8 freeway through Arizona and a part of southern California tomorrow night, passing through grids DM22 and DM32. As of now, my plans are to return home sometime on Sunday (19 February). I don't have to drive the most direct route home, but that route would go back through the rarely-heard grid DM32. Or, based on some Twitter discussions a couple of weeks ago, I could make a long loop into southern California and work from grid DM13 once again. Or I could go north, heading back to the DM23/DM24 grid boundary - a place I operated from a couple of weeks ago. Any preferences? If so, please let me know by e-mail or at my @WD9EWK Twitter account. Thanks in advance, and 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/ Twitter: @WD9EWK

Re Dashboard
by David G0MRF 15 Feb '17

15 Feb '17

Hello David. Firstly, thank you for all the data, I have seen your call on the warehouse earlier. -298 frames and counting. This is my limited understanding...... The warehouse is totally happy with the data arriving from any souce i.e. different dashboards. Each frame transmitted from a funcube satellite or payload, includes a satellite identifier. This tells the warehouse the source of the data so it can store it appropriately. It also applies the correct decoding equations for the raw data transmitted The sequence and frame numbers are used to sort frames into correct order (some may be played back after a pass) they also prevents duplicates and set a time limit on when a particular frame will be accepted. If a dashboard for AO-73 receives data from Nayif-1 or UKube (or FUNcube-X) it will send it to the warehouse where the sat identifier is used to store it correctly. The issue is that the dashboard used at your QTH will only display the data correctly for the spacecraft it was intended for. Our hard pressed software team is working on a single dashboard for all the FUNcube satellites / payloads. It is a work in progress. This will be particularly useful when ESEO is launched as this satellite will have 1k2 and 4k8 bit rates and for another project which will transmit images. Please bear with us. So many things to do and so little time........... 73 David Gentlemen, Can I run both the Funcube AND the Nayif dashboard at the same time. It appears they both decode the data when connected to the receiver output. Will this confuse sending the correct data to their respective warehouses? Trying to reduce the amount of switching between Funcube,Ukcube and Nayif. With Nayif arriving in between Funcube passes the automation has taken a backwood step. Thanks David David G.

Nayif-1 TLEs
by David G0MRF 15 Feb '17

Hi Greg. The transponder was on during the last pass over Europe. As far as I know the team in The Emirates have left the satellite in a mode where the transponder is on in eclipse. So, it should be on for tonight's passes over North and South America. The signal every 5 seconds should show up as 2 lines lasting 700mS. The telemetry data is transmitted for 4.3 seconds between each burst of tones. (but it sounds just like noise.) All reports appreciated. And videos ! Thanks PY5LF David Oh, wait... Just ran Fabricio's recording through fldigi, and I see TWO lines (tones) during the 1 second pulses, each looking about like what I saw. So, the modulation is really wide, compared to what I am used to seeing. Didn't catch that during my pass. Will check again next time. Greg KO6TH

I also received a carrier around every 4-5 seconds.. I sent KO6TH and KO6TZ a recording of the carrier and they both confirmed the same,.. The Transponder however was not ON ... JACK-KC7MG
