EQUiSat Optical Beacon CubeSat
by Trevor . 17 Oct '18

17 Oct '18

Students at the Ivy League Brown University are developing an amateur radio satellite EQUiSat that will carry a Xenon Flash Tube (XFT) subsystem to act as an Optical Beacon that should be visible to the unaided eye of observers on Earth.

LVB Tracker USB serial port driver for Windows 7 x64?
by Bill Bordy, NJ1H 22 Dec '16

22 Dec '16

Has anyone located a driver for the LVB Tracker internal USB to serial port adapter on Windows 7 x64? If not, has anyone reverted to the serial port connection on LVB Tracker and used an external USB to serial port adapter successfully with SatPC32 on Windows 7 x64? I have an Edgeport multiple USB to serial port that has drivers for Windows 7 x64 that I will use if I have to. I would prefer using the LVB Tracker with its USB to serial adapter if someone has another solution. 73, Bill NJ1H

AO-16 telemetry 3 Oct 2010
by Mark L. Hammond 01 Jul '16

01 Jul '16

Hi All, Here is a quick AO-16 update. On Sunday I turned AO-16 long enough to get some telemetry packets. The satellite would remain on for less than one minute after being commanded on. A quick test of the "bent pipe" voice mode repeater was successful. . The "hardware watchdog timer problem" is still evident; as expected, spacecraft temperatures are insufficient to keep the transmitter ON (needs to be above 15 deg C). Orbit projections suggest that satellite illumination conditions will not result in increased temperatures for nearly 10 years. Command stations do periodically turn AO-16 "ON" to check on its condition and see if the hardware timer problem has "automagically" fixed itself (which in not anticipated, but who knows...).

Great job, Skyler, on the satellite net this evening. Although just a dozen or so checked in, there were more lurking - and, hopefully, learning and getting interested. Heck - one of your participants even offered a donation to your school's ham club! Clint K6LCS

AO85: interesting results
by Ed K9EK 31 Oct '15

31 Oct '15

Note on just copying AO85 on the 1845Z pass (in high speed mode): Normal method of copying telemetry is with FCD+ fed by a 2M splitter that also feeds a TS700 2M transceiver. Works. Tried something different: Instead of having the FCD listening on 2M, I had it listening to the 10.7MHz IF output tap of the TS700. Then I tuned the TS700 strictly for best eye pattern. It worked; the lower right counter added 63 packets in half of a pass (a million trees and a great big hill to the north here). Most packets ever. Now the strange parts. The TS700 was tuned to 145.964. A bit lower than expected. (I normally hear audio at 145.980). And the best eye pattern was obtained (without automatic signal tracking) with the two peaks of the telemetry offset half the passband to the right of FoxTelem's centerline indicator. Seems odd, or am I missing something? BTW FoxTelem is an astounding piece of software. Wow. Ed K9EK EM69xd

AO-85 in Data Mode over EU
by Jerry Buxton 31 Oct '15

31 Oct '15

We just commanded AO-85 into Data Mode which is the high speed telemetry and hopefully it will still be in that mode 15 minutes from now when it comes into view over Europe. Please switch your FoxTelem to high speed on the Input tab to capture what you can before she switches back to Transponder Mode. Thanks, from the Fox Team! -- Jerry Buxton, NØJY

ARR preamp modification
by jeffory broughton 31 Oct '15

31 Oct '15

For those of u who are using a very hot VHF receiver like the Ic 910, mine specs at .11 uv for 20 db, I found the ARR mast mount to have too much gain. I replaced the 78l05 with a 78l033 and realigned to reduce overall gain and noise figure. I never used the preamp because of this problem.Now when I switch the preamp on and turn the ATT on, I can Dig a noisy signal out of the dirt like never before. Marginal copy way down below 1 degree becomes 59 .amazing. WB8RJY JEFF jeff broughton
