[amsat-bb] Re: Improving performance of packet communications through the ISS

PASSALL does not work with AGWPE but if you want to improve reception of  
aprs packets from ISS the best option might be dire wolf, it is a direct  
replacement for agwpe and tries to fix reception errors.
It will very likely out preform any hardware tnc for aprs use.

Another alternative is uz7ho soundmodem, it is designed to handle shifted  
and distorted tones on hf and could help at iss too, this is also a dropin  
replacement for agwpe.

Les...

I forget the command...maybe PASSALL? Typically the default settings only
display complete verified packets...I think if you turn it on it will
display partial and unverified packets which allows you to see everything
received even if  incomplete and can you can figure out the content.

I've got my Icom IC-910H working with it's SignaLink interface, through
Packet Engine Pro and UISS. I've been able to receive lots of stations
through the ISS, and managed to have short QSOs with a couple. Fun!

But I notice that this combination seems to do a poor job of decoding
weak signals. I hear packets in the speaker that seem plenty strong
enough to decode, but they don't show up on UISS.

I'm wondering if I used a traditional TNC, such as a Kantronics unit, if
I'd get better performance? Does anyone in the group have any experience
along these lines? Or could someone provide other suggestions on how to
improve my ability to communicate through the ISS?

Thanks in advance. Having a ball on the birds.
