At 1748z today 26 Nov, in Maryland, I heard what sounded like a solid
carrier on 145.825 Cape frequency with clear spin modulation. It was
right on schedule with the other Wallops launch birds. Like I said,
sounded like a carrier only, so the spin modulation of the antenna was very
obvious. Though it could have been some other data or modulation.
Just thought Cape would like to know. Come to think about it, the rate was
pretty high like 1 RPS and I doubt it was spinning that fast, so donno what
it was. I was late for a meeting with my boss, so didn’t have time to
figure out more.
After not being able to get into AO73 last night I today reloaded my keps.
I noticed that AO73 had a newer element set then I had before.
As a result tonight I did get into AO73 and worked KC9ELU and K8YSE.
I did have to retune my transmit every time I started talking.
This is something I usually don't have to do on other satellites.
So hopefully as the keps improve, so will the accuracy of the tracking programs.
Only time will tell.
I was impressed with the strong signals considering it was in the low power mode.
I have a ten tec 2510 that needs the dial string re strung...I took the
front panel off and see that there is some black string and a spring
hanging there, along with a thinner string around the dial shaft.
I have no idea whats right and what needs to be done...can someone send me
a picture of what a correct dial string looks like, please?
I was able to be in the yard for an AO-73 pass at 0523 UTC this evening.
Following advice on which element set to use (2013-066B) and to go up
10 kHz higher than the originally published uplink, I was able to quickly
find myself and work a couple of stations from my yard in DM43bn.
Angelo N5UXT in New Orleans (EM40) was my first QSO on this bird, then
Jack KC7MG south of me in DM42 called for his first QSO on the bird.
This was a high pass, maximum elevation of 72 degrees, covering much
of the continental USA at this late hour. There was some CW sweeping the
transponder, but I was able to stay around 145.965 MHz on the downlink
with nothing more than adjustments on my uplink frequency. High power
is definitely not needed for this satellite.
My station was my usual portable all-mode setup - two FT-817NDs, Elk
handheld dual-band log periodic antenna. Transmitting at 5W, I could
hear myself early in the pass. I need to do better twisting the antenna at
both ends of the pass to have an easier time copying the downlink. At
the midpoint of the pass, I cut my power down to 500mW. I could barely
hear myself, weak but readable. I will try the other two power levels the
FT-817ND has on other passes, to get a better idea on how sensitive the
satellite's uplink receiver is. I should also be able to hear the transponder
on my TH-F6A HT, my backup radio for satellite work.
I hope to publish a little video in the next day or so with the audio I
recorded and photos I took. No rain tonight, but the temperature was
around 50F/10C when I was on the radio. My dog didn't want to stay
in the house while I was playing radio, so she ran around the yard. I
will put a photo or two of her in the video.
Thanks to AMSAT-UK, AMSAT-NL, and everyone who worked to get
FUNcube-1 (AO-73) in orbit and operational. Good night, and 73!
