Hello All, I've been trying to stream NASA Television into our television repeater CH 39 UHF here in Auckland for some time now. This will reduce the potential risk of radio hams losing CH 39 UHF. Raido Hams have recently lost 440 MHz to 449.750 MHz our previous TV reapeater input frequency. I know that the CH 39 UHF power levels are low with new linking equiptment being constructed and purchased.A power up grade is on the cards also. We have a high power broadcast tv transmitter but nowhere to install it without complaints (resource consents, power and site costs etc).We are unable to run this high power transmitter at our current site as there is no room for it. The club arrangement is a non profit order.This is a problem also. I hope this year will be an expansion year for CH 39 UHF. Currently we are under pressure such as the MED,RSM UHF TV call to for expressions of interest for community tv licences (CH 35 to 42).The other option is to apply for an ad-hoc licence after the first round of community licences have been let.If there are any left.Yes,ad-hoc as the MED,RSM call it. Link to MED. http://www.med.govt.nz/rsm/licensing/uhftveoi.html NASATV cannot be pulled off direct satellite here in New. ----------------------------------------------------------------------------------------------------------------------------------------------------- Multicasting I've not had the support from large ISPs to accomodate this. The CH 39 UHF Television Radio Ham exercise runs at low cost. Were trying to promote NASATV and encourage the public of all ages to get educated and have fun on the internet and internet ham radio. NASATV has many web sites constantly informing the world wide public to gain access and learn something in their lives.These web sites are often transmitted via CH 39 UHF and hopefully promote and encourage people to become aware of the need to have internet comunications.Get connected and live again. I see this as a win,win for all. 7kbps to 13kbps is not what broadband is about.The buffering is on and off constantly. My Jetstart service has some what been reduced ( some services disabled,Load Balancing ,IP assend IP desend,Multicasting disabled etc ). I have two Jetstart accounts with Telecom Xtra. All I really need is a quality multicast connection at no less than 64kbps.I can't de-compress 28kbps well enough to an acceptable level,tv-out full screen etc.100Kbps is even better but too costly at present.300kbps flys and de-compresses well.Its very expensive and still stops and starts with no connection or 7kbps to 16kbps with no picture and audio breaking up. Whats missing in customer contracts is the information disclosing what features (hardware or filters and services) are disabled or dis-allowed.A customer believes that they are purchasing full access to where they intend to connect. Thanks all, Wally Muzyka, Radio Ham ZL1VWM, NASATV Supporter. Email: zl1vwm(a)xtra.co.nz PS: The Auckland VHF Group club rooms can be made available for a group of say up to fifty people if you get stuck sorting out a place for your first NZNOG Conference.It's in Hazel Ave,Mt Roskill.The building is of school class room size sited on the Council Reserve.I know of another radio ham Simon from Cisco who may wish to rally up support for NZNOG.There are other radio hams that work in the IP industry also.Would you like to invite them to NZNOG Conference also or have a closed meeting instead.
Wally, firstup, as a ham radio op type person myself, kudos to you for doing this. :) I know exactly what youre facing in terms of our bandplan gradually getting sucked away...

The issue becomes that of focus. Most of the issues facing network operators in NZ today are very much..um.. seperated from areas which have direct influence on Amateur Issues. I.e. I dont see all that many amateurs (in a general sense) having a direct interest in much of what would be topical for an NZNOG Conference. Of course there are exceptions :) I do however think, knowing the club rooms at Hazel Ave, that it isnt necessarily ideal. Although it'd be interesting. :) Cheers and 73 Mark Foster (ZL1VMF) PS - to subscribe to nznog you need to email majordomo(a)list.waikato.ac.nz with 'subscribe nznog' in the body - dont email the list itself.

Unless the facility has undergone a major upgrade in recent years, it doesnt even have a bar :-) Peter Mott ZL2DAY It's kind of fun to do the impossible - Walt Disney -/- - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

No one will be able to hekp you there. There are several factors conspiring to stop you being able to recieve a multicast stream of NASATV: 1) The NASA TV multicast stream is ~1Mbps in size, so you would 15 or 16 jetstart connections. 2) The NASA TV multicast stream no longer appears in SDR advertisements, and doesn't appear to exist anymore. 3) I doublt you could easily build a DVMRP or PIM tunnel to load balance over n + 1 jetstart connections. I would suggest that you stick to the unicast stream: http://www.nasa.gov/ntv/ Cheers. --- James Tyson Moebius Systems Ltd http://www.moebius.co.nz/ - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
