Message-ID: <8d3dbac5-4e0e-4efc-bffe-64be9ce1f1f1@???.????????.???>
Content-Type: text/plain
Hi Folks,
I would love your opinion on my next steps.
I've been slowly putting together a station. I finally got it operational
and I'm having a really hard time hearing anything other than morse code off
satellites (mainly the XW birds). I can pick up some voices from the linear
transponder, but it's too buried in noise for me to make out.
Key Facts:
* For an antenna I'm using a yagi I built from "Cheap Antennas for the AMSAT
LEO's Kent Britain -- WA5VJB"
* fixed elevation of 15% on a rotator.
* 50 feet of LMR-400 (in 30/10/10 segments) running from my shack on the
first floor up to the 3rd floor balcony where the antenna is.
* UHF Connectors
* SDRPlay RSPdx for receive.
* no common mode chokes on either end of the transmission line
* Live in north seattle, so bunch of noise already
* ton of computer equipment in my shack with more switching power supplies
than I can count.
* LED lights, though I think I already sleuthed out the really bad ones.
So...what are people's thoughts? Would an LNA help drown out the noise in my
house and compensate for cable loss? Or should I start by doing the lengthy
process of finding and ameliorating as many noise sources as I can first?
Thanks,
Chris

To determine if an LNA will help, I'd try listening to a few passes
using a short run of coax (<10 feet) right at the antenna if it's on a
balcony. Drag a laptop and the SDRplay up there. If you get
significantly better reception, then yes, an LNA will help.
Reducing noise sources is always something that should be done, but if
you're in a city, realistically you probably won't make a huge dent
without turning off almost everything in the house.
And if you have the room to build a bigger yagi, that will always help too.

Hi Bernd,
Yes I am using a Java version of the old sgp4 library that uses the
standard TLE's for the orbital calculations, and then I added my own code
for transformations and stuff to get to AZ/EL for a given location and time.

I now have sat32/scope working nicely. last week before I added the cat v??
cable and upgraded to the scope? version, I had set up wstj to the ic 9700.
I had not actually used it or decoded any signals.
It occurred to me that WSJT is controlled only thru usb. I dont see any
option to run cat to the wsjt and get audio to it just like? sat32 scope?
I hope some one has accomplished this.
I am hoping to try at least to hear /decode something from Reno on WSJT, but
I expect it will be a tall order.
Thanks

Nice progress, Jim. For WSJT, Just be sure SatPC32 is exited, then run
WSJT. Configure to use only the USB port, and it will use that for both
audio and rig control! It?s easy. Just don?t run them both (SatPC32 and
WSJT) at the same time and it all works great. Back and forth between them
is nice.

Hi James,
Glad you got SatPC32 working. By using the separate CAT cable you still
will be able to use computer control of frequencies etc, even with other
programs if they use CI-V commands. Just specify the CAT com port and speed
and radio address (if needed). Now, the scope function will occupy your usb
port and if you try to use other software at the same time with the IC-9700
you will create conflicts. You might try virtual serial port (VSP) software
to split that port. Not sure if that will work.
However, help me understand why you would want to run SatPC32 together with
WSJT? Are you planning to use weak signal digital communication over
satellites?
If you are just interested in the "scope" function for the IC-9700 got to:
https://icom.va2fsq.com/win4icomsuite-overview/ and try the software. It
will work with WSJT and gives you a scope.

I may have misunderstood your question but the scope data to SatPC32 is not
audio. It?s data sent via the CAT connection on the USB cable.
You can use the USB audio Device the USB connection also offers to connect
to the sound card in the radio from WSJT-X.

Thanks, Heimir and Joe. I?ve been playing with this today on a ESP8266
module and it works great so far. An array of all available sat names would
definitely be welcome, look forward to that.
I do have one wishlist item though. Something like name=ALL would be nice so
that we wouldn?t have to hammer the AMSAT server with many requests just to
get all the data for all available satellites.
Thanks again for adding JSON support, it?s definitely appreciated.

That is a good idea Mike. I don't see why that can't be added.
