Burns,
Thanks to have put in better words what I was trying to explain, sure it
will help Shakeel.
I use HDSDR this side and works perfectly.
May be to add on the topic, one may also use the SDR IQ (need to use 192K
sampling rate).

Good point, Jean Marc. Thanks.
And BTW, I of course meant in my original post that most radios do not spec
the LOW frequency of their output.

Burns,
This is the beauty of this forum, thanks to AMSAT, basically we may exchange
experiences and knowledge, and debate about same.
My personal opinion is that no-one has the monopoly of same mentioned above
and sharing brings us all to new heights, enable all of us (and the Ham
community in general) to achieve things that just a few years ago one would
not imagine.
Thank for sharing and 73

Wondering if its just me or does it seem like the deviation is low on these
sats. I can not distinguish which one I am hearing since I can not decode
anything yet. I used to copy the ISS packets no problem.
BTW has anyone heard any FM voice beacons ?

Earlier today, I submitted requests to the Heavens Above and AMSAT sites

My D72/Elk was able to decode a few packets from each of the
callsigns, but not display them as they appear to be non-standard APRS

The ISS packets were very strong compared to these, so that could be
one reason. What antenna/transceiver/tnc are you using?

Hi Roy,
Im using the Sound Modem by UZ7HO and UISS vers 5.4 that I used on ISS
passes and can monitor local APRS traffic.
Antenna is dual band Jetstream fixed at 25 deg elevation on AZ rotor. Setup
works great on all the linear and FM sats but wanted to try something new.

I have a IC-746PRO. If I can get a little time, I'll try decoding this
with my rinky-dink antenna setup using the 9k6 output on the back of the
rig.
... and I'll write Santa for a IC-9100 :-)

Thanks Scott and Roy. I listened to Scott?s clip and that?s what I am
hearing here.
The ISS voice repeater was on a few days ago. I later read that was being
used to relay the packets. I did make a FM contact via the repeater before I
realized what they were doing. I did hear stronger packets via that method
but was not setup to decode as it caught me by surprise.
Its still a lot of fun if not just a little frustrating ?

Same here. I've monitored numerous passes and the SNR is just too low.
Here's a tweet I just posted w/ a link to how the audio sounded at my end:

... setup is a 2m X-Quad w/ AZ/EL tracking. Both UZ7HO Soundmodem &
Direwolf (iGate) are using the audio from my TM-V71A which does very well
with PSAT, FalconSat-3, & terrestrial 1200 packet. Of course worked great
with the ISS digipeater also.
So, they've just got too little RF power, deviation, antenna... or
something.
By the way, the 70cm CW beacons continue to operate on 437.375 & they are
pretty strong.
