Problem with wispdde
by sjdevience＠gmail.com 09 Apr '21

09 Apr '21

Wispdde is misbehaving, and I'm looking for advice about whether it can be fixed, or whether I should give up with it and try gpredict. I'm trying to control two SDR radios via orbitron and wisp on Windows 10. The receive radio is run with sdr#, with a cat control client providing bidirectional control from wisp. So wisp/orbitron tracks the doppler, and I can click on the waterfall to select a frequency, which then gets sent back to wisp as the new RX frequency. That by itself seems to be working, although it's kind of slow to respond. The uplink frequency from wisp gets sent to another radio via cat control. That by itself also works. The problem is when I use it all together. When I start out wisp, it all works, with the correct uplink sent to the TX radio and the downlink sent to the RX radio. However, after the very first frequency update, wisp puts in an uplink frequency in the same band as the downlink! So for example for RS-44, I start with 145.939 and 435.668, but then it changed to 435.668 in both uplink and downlink. Has anyone else seen this behavior? -Stephen DeVience N8URE

M2 LEO pack - which polarization to use
by Don Solberg 09 Apr '21

09 Apr '21

In the past I saw a lot of discussion on if it was better to use RHCP or LHCP, but today most of the LEO satellites use linear polarization. I may be mistaken but the only LEO satellite that I know of that uses circular polarization is SO50, which uses LHCP for the 70 cm downlink. I am in the process of replacing a dual band linear antenna with the M2 LEO pack. I was thinking about setting the 70 cm antenna for LHCP and the 2M antenna for RHCP. This would maximize the downlink from SO50 but also give me a lot of attenuation between 2M and 70 CM which would help with desense. I have a desense problem with my current Cushcraft antenna, even with a diplexer as a desense filter. For the LEO pack antennas I will not be using M2's aluminum boom, but instead have a 12 ft fiberglass boom. Am I missing something or is this the "best" way to go? Most of my operation is thru the linear SSB band birds. 73, Don K9AQ

AO-91 still operating 9 April 21
by Mark L. Hammond 09 Apr '21

09 Apr '21

Hi All, Tweeted this a bit ago, copied here now. AO-91 remains operational in COR or "repeater mode." Reminder: Please use only in sunlight and do not use while in eclipse (which "generally" means, if it's dark at your local QTH do not use!). 1245utc 9 April 21 73, Mark L.

SCS PTC-IIex on FalconSat-3
by Bill Erhardt 08 Apr '21

08 Apr '21

Howdy gang, Happy to report that I built a cable for My FT-847 6 pin connector to my SCS PTC-IIex connection and copied and sent to FalconSat-3. I mainly used my SCS modem for Winlink and after some reading it also does Packet at 300 1200 9600 and 19200. Pinout on the Yaesu has a 1200 and 9600 so I wired both. Packet speed is changed in the Yaesu FT-847 Menu #23. I tested 1200 on ISS simplex with UISS/ SGATE and FalconSAT FULL Duplex Satellite Mode with TX on 145.840 and downlink on 435.100. What is nice is SATPC now changes the Doppler and and Pacsat Ground station is much happier. I used my Kenwood D-710GA in full duplex but I had to hook up the antennas every time I got on Falcon Sat then back to my FT-847. I also tested my Signalink with the 9600 baud full duplex on the FT-847 and got it working correctly. To wrap it up it will be nice not changing antennas any more and I am going to try the early Falconsat in the morning to see if it will run totally automated !! Having way to much fun Bill K7MT DN46 Helena, Mt.

ARISS anticipates that the contact would be held between January 1, 2022 and June 30, 2022. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan.

These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact.

What "Mode" in LoTW do we use for a contact via ARISS APRS? They used to list "Packet" but I don't see that anymore. There is a PKT, but I'm not sure if that is right. Just use FM? What's the standard procedure? My thanks in advance for your assistance! 73 Steve AI9IN EM79ji

Spacing of Circular Polarized antenna?
by marzo7088＠yahoo.com 07 Apr '21

07 Apr '21

I am building 2 Circular polarized satellite antennas.They are omni Moxons, a variation on Turnstiles.I by accident used the wrong length pipe for the spacing.Ended up putting on the shorter pipes that were to supposed to attach to the antennas.Is about 4 feet spacing OK?Or should I get some couplers and extend them? My original plan was 5-6bfeet spacing.I was more concerned with interference, I think the physical spacing of the antennas will fit. Thanks Rich

SatPC32 And Green Heron RT21: "Limits" not obeyed
by Bob KD7YZ 07 Apr '21

07 Apr '21

Anyone notice that when tracking a bird that SatPC32 will go far above the limits set for Az & El within the Green Heron's own "RT-21 Setup Utility" program? I double-checked that the limits for Elevation were to go no higher than 50 degrees. A bit ago I was tracking CAS which was making an 86 degree pass over me. I was on CW listening to my "VVVVV" 's ; looked out the window, to see the antenna was at 86-degrees and inches from being driven into my roof! -- -- 73 Bob KD7YZ
