I was just able to send VARA FM WIDE Mode with a 6700 and no special settings, but I used FM mode (standard 16KHz filter), versus DFM. My equalizer was turned off, but both my Tx and Rx DAX Gain settings were set to 50, the half way point. In VARA, I was set to -10dB.

I am running SmartSDR V3.1.12

I am attempting to use my 6700 with a DownEast Microwave transverter and LDPA to operate at 9600 bps on the FalconSat-3 satellite. I am using DFM at 20 kHz bandwidth and have good copy on the downlink signals on 435.1 MHz. However, I cannot make the satellite hear my uplink. I've tried a wide variety of settings, but no luck. This shouldn't be so hard.

Can you let me know which modem and SSDR settings you were using to copy the 9600bps signal from FalconSat-3? I have a good strong signal from the satellite using an Oscar array with az&el tracking but no luck on the copy so far thanks for the help.

Mark, K0JM, is using FlexSATPC software in conjunction with SATPC32 to copy FS-3 9.6K Packet. FlexSATPC applies the settings specified in my post dated May 2020 to allow FS-3 Downlink (9.6K packet in general)

This works with AGW PacketEngine (Pro), MixW and UZ7HO hs_soundmodem software.

The issue of uplink not working has been reported to Flex along with detailed information as to why it's not working.

Note that a couple of the settings must be done via Flex API based software, they are not user settings in SmartSDR .

You can email me (good in QRZ.com) if you are interested in FlexSATPC software.
