Digital Modes on Linear Sats
Information, please. I'm in my 70s, and DXCC SAT is on my bucket list. I'm slowly making progress with 61 entities/59 confirmed. Someone on the BB once suggested to me that I make use of digital modes to up my total. But ... before I do so, and also be sure to use low power on the bottom of bandpasses, I'm curious to know what kind of digital mode activity there really is on linear sats and what DX stations (in rarer entities) folks have actually been able to contact. Then and only then will I consider taking the plunge and buying software and hooking up a PC. CW and SSB are still lots of fun. I do not work FM sat. I'm available anytime, by the way, if anyone needs FN54/Maine. Thanks.

Hey Wes. First off thank you for FN54. The addition of digital modes on the Sats does give you more options. I often see posting by Europeans using digital modes to access the US. I have used it quite a few times and my initial Alaskan contact on the sats was by FT4. Couple of anecdotes, My first Peru contact was also by FT 4 ant was less than 5 degrees the antenna was pointed toward my house and usually need about 15 degrees to access by SSB. The other, here in EM20, Europe basically cannot be accessed, a few times I have pointed my antenna that way when the sat is below the horizon and have decoded a station at -3 degrees on RS44. I think it was Belgium. probably impossible to do now with a new building just erected in that direction. The use of the WSJT-X software is fairly easy to set up and I know of it's usage with the IC-9700, IC-9100 and the TS-2000. In my case i use the IC-9700 with a CIV cable to control doppler in the radio by SATPC32 (The CNC S.A.T. Controller should work well also). PTT from WSJT-X is through one of the USB Ports by using RTS or DTR. The toughest part here is to determine which of the 8 combinations works best. (2 Computer USB Ports X 2 IC-9700 ports X RTS or DTR). CheersJerry - N5EKO On Thursday, October 6, 2022 at 03:32:24 PM CDT, Wes Baden [email protected] wrote:

I'd like to give this a try. Is there an operating protocol? For example, do I just pick one of the time slots? (TX first) Or, do I need to be in a certain part of the transponder's pass band? Tips are appreciated!

W7IY" Hey there Stu, Per Gentleman's agreement we stay about 3-10 khz above the bottom of the Passband and usually operate on RS-44, FO-29, AO-07 and HO-113. Sometimes we access the other linears late at night when there is less usage.As far as Time slots, it's up to you. You will see signals as you transmit. If you need help or tips join us on Zoom at http://www.k5wh.net/zoom.%C2%A0 Usually always someone there to help out with satellite things.

I'd like to try this (WSJT on SATS) but I see a problem. I recently set up WSJT to work with my Icom 9700 for the purpose of setting up a moonbounce station. WSJT does the CAT control (for Frequency setting and PTT) of the 9700 and also swaps audio signals with the 9700 via a single USB cable using two COM ports. For Satellites I use the CSN Tech. S.A.T. controller which controls the Icom through a separate CIV cable. I want to continue to allow the S.A.T. controller to manage frequencies (doppler shift, etc.) but I looked through the WSJT user guide and don't see how to turn off the CAT frequency control. Help, please? Thanks ES 73, Barry K6RM

Sometimes we access the other linears late at night when there is less usage.As far as Time slots, it's up to you. You will see signals as you transmit.

Hey Wes. First off thank you for FN54. The addition of digital modes on the Sats does give you more options. I often see posting by Europeans using digital modes to access the US. I have used it quite a few times and my initial Alaskan contact on the sats was by FT4. Couple of anecdotes, My first Peru contact was also by FT 4 ant was less than 5 degrees the antenna was pointed toward my house and usually need about 15 degrees to access by SSB. The other, here in EM20, Europe basically cannot be accessed, a few times I have pointed my antenna that way when the sat is below the horizon and have decoded a station at -3 degrees on RS44. I think it was Belgium. probably impossible to do now with a new building just erected in that direction.
The use of the WSJT-X software is fairly easy to set up and I know of it's usage with the IC-9700, IC-9100 and the TS-2000. In my case i use the IC-9700 with a CIV cable to control doppler in the radio by SATPC32 (The CNC S.A.T. Controller should work well also). PTT from WSJT-X is through one of the USB Ports by using RTS or DTR. The toughest part here is to determine which of the 8 combinations works best. (2 Computer USB Ports X 2 IC-9700 ports X RTS or DTR).

Information, please. I'm in my 70s, and DXCC SAT is on my bucket list. I'm slowly making progress with 61 entities/59 confirmed. Someone on the BB once suggested to me that I make use of digital modes to up my total. But ... before I do so, and also be sure to use low power on the bottom of bandpasses, I'm curious to know what kind of digital mode activity there really is on linear sats and what DX stations (in rarer entities) folks have actually been able to contact. Then and only then will I consider taking the plunge and buying software and hooking up a PC. CW and SSB are still lots of fun. I do not work FM sat. I'm available anytime, by the way, if anyone needs FN54/Maine. Thanks.

Give this a shot:

Video for SatPC32, but the WSJT-X settings are the same-ish for the SAT Controller. Set rig to None...

If you are on facebook their is an ft4 on sat group. Many people use the CSN Sat tracker. you can ask the group.
