Ouch! Meant to say WLM.

Greetings Ken,

You've basically figured it out yourself actually. In most situations without UPnP,
Messenger will just use a Microsoft relay server which naturally won't give you the same sort
of bandwidth and fidelity you get with a direct connection.

Tto be honest, I think you would get far better quality by using a product/technology
intended for streaming music (assuming that's what you're listening to on the radio) like
Windows Media Encoder or a similar product.

Thanks Jonathan. I noticed that you provide a lot of help on this
newsgroup. The audio I am attempting to transport is just communications
grade voice for Amateur Radio, no music. Bandwidth is less than 4 KHz and
dynamic range less than 30 db. The connection is bi-directional and
simplex like a back-and-forth conversation. The link is shared with a
Remote Desktop Connection session. We have been able to do this using
SKYPE for the audio transport, although SKYPE is fussy about background
noise and its AGC is sometimes overwhelmed by dynamic signal levels and
echoes. We have a UPnP router at the sending end. Now I have to get one
for the receiving end. Best Regards. Ken Fowler, KO6NO
