I had a decent pass just now, Saw mine as well as a few other signals and the telemetry.
Key word is I "SAW" in the waterfall these signals.
BUT.. not one of them would decode.
Anyone have a guess what might be happening?

Hi Joe,

I'm in the Chicago suburbs. The most recent pass was nearly overhead for me. I copied the same as you described. There were signals in my waterfall but none decoding. The downlink signal sounded much weaker than usual (by ear). The findu.com page logged only one station getting gated and a few telemetry packets.

Exactly! i WAS USING fl-dIGI FOR SOFTWARE, HOW ABOUT U? Joe WB9SBD Sig The Original Rolling Ball Clock Idle Tyme Idle-Tyme.com http://www.idle-tyme.com On 1/27/2017 11:30 AM, JoAnne Maenpaa wrote:

I was on the 145.825 packet digipeater aide. With Fl-digi I think you were trying the PSK side. The next pass at around 11:45 AM central time was about 20 degrees elevation and I could barely copy the 145.825 downlink on that pass. Also, no USA stations or telemetry were gated to the findu.com site.

Yes I was trying to use the 435 psk-31 ummm transponder? ya know 10M up 70 cm down Joe WB9SBD Sig The Original Rolling Ball Clock Idle Tyme Idle-Tyme.com http://www.idle-tyme.com On 1/27/2017 1:32 PM, JoAnne Maenpaa wrote:

Joe,
I was not on that pass.
Most of the time, you will see the telemetry very strong down at 310Hz. You should see your own signal where ever you put it. (I use 1600Hz) You should also see the non Doppler corrected beacons. These skew across the waterfall. Won't waste time trying to copy them.
Now for FlDigi... The maximum acquisition range is 500 Hz. If the signal is not within the "Red" bar limit above the waterfall, the program will not look for it. Also look in the configuration for multi option being selected.
CONFIG/OPERATOR/MODEM/PSK/MULTI
As a frequent user of NO-84_PSK31, I recommend DigiPAN or WinPSKse. They each have their advantages. DigiPAN copies many signals with limited AFC. WinPSKse copies only two signals with 3,000Hz of AFC. Your choice.

Would it be a good idea to mention what you use for uplink doppler correction? I assume Andys K0SM's DopplerPSK?

Yes I use that also. For Transmit.
I was using FL-Digi for recv, but the single channel I know I was missing people calling me.
I tried some of the others that use a multi trace capability. but wasn't too happy with it.
But just now tried ACDS, and was quite impressed on it's working. The 34 seperate ummm channels or passbands? anyway,the being off freq, or freq sweeping too fst will not it seems to be a problem with that program.
