I was using Ham Radio Deluxe, but found the way it would do the doppler very intrusive, I already owned SatPC32, but found the UI difficult to use, but this video really helped me. What I do now is to use SatPC32 for the radio control, and HRD for the visuals, maybe not everyones cup of tea, but it works for me and feel like I stand a better chance of operating the satellites with the frequency and modes being correct via SatPC32 and the visuals spot-on with HRD.
I tried to use SATpc 32 last year with my 9700 and Yaesu 5500 rotor. I also had the HRD program and discovered that the SATpc32 showed the wrong positions for the birds and often had the wrong frequencies and or reverse upload and download. I just watched this video and tried SATpc32 again. I also have a brand new Geochron with the Ham add on. Well the SATpc32 does not show the proper position for the birds. What am I doing wrong? What is wrong with the program? I ended up getting CSN Technologies S.A.T. It works fine and agrees with Geochron.
Both HRD and SATpc32 work correctly. If you have a pointing issue, then either you have the wrong keps loaded or the wrong operating location. You will need to review your settings for SATpc32. As for frequencies, you do need to edit and review the doppler.sqf file for correctness. I have hundreds of QSO's using SATpc32 that have been flawless with perfect uplink and downlink tracking and once I put my RX on the person I want to work, I never touch another knob. As for what you are doing wrong, you may want to get on one of the groups and have them review your settings in SatPC32. I agree, it is complicated to learn. The manual does help. See if someone will share their doppler.sqf file.
Hi Michael, Thanks for posting this. I’m in the brainstorming stage of setting up a portable 10GHz system. During lockdown I completed a few projects such as commissioning a DMR repeater and setting up an up/downlink system for the QO-100 satellite - look up Denby dale M0SNR and you will find my presentation. Not sure if you have seen Rex VK7MO’s EME video’s but he is an inspiration :) 73.
Are you using a Gunn oscillator in the rig? Saw a 10 giga Hz Tx in an ARRL handbook back in the 90's. Would love to do some mountain top work in the mountains back in NM.
They dont make these antennas anymore I dont think. I used to own two of them and sold them like an idiot. I would love to have them back. I also had an NCC2 and the ARAV units and the NCC were absolutely stellar!
Interesting and wow, what a difference. I use an 66ft endfed and just have quite a bit of noise. Have you tried any other antenna types for comparisons like you did with the windom?
I was lamenting that Icom in the 9700 did not allow cw send while in ssb sat mode. Then I saw your video and the 'light' went on... If I pick cw, then I don't have to learn to whistle, I can send a series of dots till I hear myself and then, shut it off... I have sent ur vid to a couple of my friends struggling with the ins and outs of this fine program. Thanks for sharing your finds... de wb7ond
" it inverts"...is this using a second receive antenna, or the Xmit antenna? I was interested in the RSPDuo - used as a phase noise canceller- using its dual antenna inputs/dual tuners for phase inversion etc. . I am missing a clear explanation on the Flex NB / DNR noise reduction you demonstrate. . Is it done in software only with one tuner, or requiring a second antenna with built in second tuner ? I believe it has diversity reception so assume your demo is demonstrating both a hardware/software NB and a dual 2 antenna & tuner phase cancellation? Tnx from a green Flex prospect.
That is one technology that is available. That is not what is happening here. It determines the 'noise' based on the sampled frequency patterns and then inverts in software.
Great information, Mike. I've been chasing my tail on this same topic. I do have one question: when you set the CAT calibration (on the uplink side) it shows the calibration value in the line above the frequency readouts above the map. But when I "Save" it in the "Change/Store Dataf File", that calibration number goes away. Did I save it wrong? Or is that number saved in the doppler file? The reason I ask, is because as soon as I save that calibration number, I am no longer sync'd with the satellite, I no longer hear myself. By the time I try the number again, the satellite is gone or I'm so far off I don't know where I am. Obviously I'm doing something wrong. Again, thanks for sharing. Craig W0AP
Are you still running this setup? I'm in a small urban plot and am looking for a better RX option. This could be it! Any input is greatly appreciated, your video made it sound like a winner.
that was the goal.. I wanted to touch on on all the things that I wasn't able to put together in the workflow. I knew what I needed to do, but I couldn't get there.
If you search here on RU-vid, there are many others with a live QSO. For the moment, that was beyond the scope of what I wanted to do for this video. Maybe later.
