Re: [digitalradio] NTS Digital
Also NTS Digital is using the various modes of Pactor, primarily Pactor I and Pactor II Many of the six MBOs in Eastern Area NTS D have the fancy SCS Modems although a few are still restiricted to Pactor I using the old PK-232 MBX... For the most part the MBOs run Classic Winlink (i.e the versions before Winlink 2000) as we prefer to forward via RF as opposed to internet We used to run AMTOR and Clover but gave those modes up...The reason we don't use a mode such as Olivia or MT 63 is because we prefer the error correction of a burst mode such as Pactor... The Digital Relay Stations that connect to our MBOs again are running Pactor but many of them are using Airmail Eastern area NTSD averages typically 10,000 to 12.000 messages a month. 73 Dave WB2FTX Eastern Area Digital Cooridnator- NTS Digital - Original Message - From: Rick W To: digitalradio@yahoogroups.com Sent: Thursday, March 05, 2009 10:32 PM Subject: Re: [digitalradio] NTS Digital Hi Dave, I have heard of the use of MT-63 for many years on MARS circuits, but don't think I had heard about the digital SSTV program being used.

Re: [digitalradio] NTS Digital
Don't know where Dave Little is getting his info, but I can tell you that NTS Digital is very active on Pactor I, Pactor II and some Pactor III... I will mainly comment on Eastern Area NTS Digital which I am directly responsible for, but similar activty exists in both Central and Pacific Areas NTS Digital For Eastern Area we typically handle 10,000 to 12,000 messages a month We have 6 24/7 MBO stations, the rest are Digital Relay stations removing and sending NTS via these MBOs...

Re: [digitalradio] NTS Digital
As an additional note... Most NTS D is using the various versions of Pactor and have the expensive SCS modems... There are some MBOs still runinng Pactor I with a PK-232 MBX... Most of at least Eastern Area NTSD MBOs are using Classic Winlink (ie. the versions before Winlink 2000) as we feel that RF forwarding of NTS is superior to internet forwarding and not subject to system outages during a disaster Some of the Digital Relay Station are using Pactor with Airmail to post and remove traffic from the MBOs... WE have not played with the typical sound card modes such as Olivia or MT 63, again primarily using Pactor with its error correcting abilities again it you want more info, please contact me wb2...@optonline.net. 73 Dave WB2FTX Eastern Area Digital Coordinator- NTS Digital - Original Message - From: David Little To: digitalradio@yahoogroups.com Sent: Thursday, March 05, 2009 10:13 PM Subject: RE: [digitalradio] NTS Digital Rick, Army MARS is using MT-63 on mixed mode nets with some regularity.

RE: [digitalradio] NTS Digital
A good deal of flexibility is gained in MARS by reason of non-mode-specific frequency allocation. I am trying to get our system to try Olivia or MT63 SSB mode on VHF, which so far has been FM only. FWIW, and IMHO, the HF MARS RMS system is effective because 1) it is restricted to compatible modes, with 2) multiple coordianted frequencies monitored by each RMS, and 3) networked RMS's disitributed across CONUS.
