Operational status of DB0NTS

The callsign DB0NTS is used for unattended operation.

VHF/ UHF packet radio

The following services are available on UHF packet radio:

Time (UTC) Callsign Service Status
From To
0000 2359 DB0NTS NTSD BBS up
DB0NTS-2 packet node up
DB0NTS-9 sysop chat up
DB0NTS-10 Winlink RMS up

Please note that DB0NTS is not part of the FlexNet routing system.

Here is a small part of the local packet radio network topology:

    DB0LHR               DB0CPU
    JN38wi               JN49fl
      |                    |
    DB0EQ  -- DB0SEL --  DB0AAI -- broken -- DB0BOS -- DB0NTS
    JN49ma    JN48iv     JN49bh              JN49lr    JN49mp
      |                    |                             |
    DB0KIT               IGATE                         DB0FHN
    JN49ea

A directional antenna is used for the link with the DB0BOS digipeater and it is therefore recommended to connect to DB0BOS (438525 kHz, 7.6 MHz shift, 1k2 packet radio, omni-directional antennas) instead of connecting directly.

The link between DB0BOS and DB0AAI is currently down. Therefore please use the link to DB0FHN to connect to the BBS DB0NTS or the node DB0NTS-2.


Direct HF access

DB0NTS offers the following services to users on HF:

Time (UTC) Frequency
[kHz]

1000 1300 reserved for future links with Oceania MBOs
1400 1930 traffic exchange with US MBOs

7049.5 Pactor 1,2 NTSD MBO down
7051.5 Pactor 1,2,3,4 NTSD MBO down
7052.0 Pactor 1,2 Winlink RMS down
7052.5 Pactor 1,2 Packet GW down

Remarks:

  • The frequencies listed above are centre frequencies.
  • The Packet Gateway will connect you to the DB0AAI packet radio node.

Scanning times and frequencies for European stations are agreed on with these users according to their needs. 80m is primarily used during the winter season and 40m is primarily used during the summer season.

Traffic with DTN/ NTSD MBOs in the US is exchanged on a daily basis. If you are running an MBO/ BBS yourself and are interested in setting up a regular sked please contact the DB0NTS sysop (see below).


Indirect HF access

A user may first connect to a HF gateway to the packet radio network and then to DB0NTS by packet radio.

    user  --HF/ Pactor-->  Packet GW  --packet-->  DB0NTS
                           station

Note that DB0NTS also runs a packet radio gateway.

Here is a sample connect to DB0NTS using the OE9FWV gateway (see qrz.com for frequencies):

    DF0NTS> C OE9FWV
    *** Connected to OE9FWV
    OE9FWV Werner QTH Feldkirch JN47TG.
    (H)elp (C)heck (C)onnect [Call] (D)ir (R)ead (S)end (TRX L)ist (Q)uit
    (R)ead aktuell for news

    next? C DB0NTS IGATE DB0AAI DB0BOS
    *** connected to DB0NTS
    DB0NTS-2} Connected to BBS
    [BPQ-6.0.13.10-IHJM$]
    NTS Eastern Area BBS for Europe
    TFC 0 FWD/ 0 DF0NTS
    DF0NTS de DB0NTS> B
    DF0NTS de DB0NTS SK

    *** reconnected to OE9FWV

    next? Q
    df0nts de oe9fwv>
    <qrt>
    *** Disconnected

The user DF0NTS first connects to the OE9FWV gateway on HF and then uses the packet radio network to establish a link with DB0NTS. After finishing the connection with the latter station the user gets reconnected to the gateway and terminates the connection there.

Client software supports gateways by connect scripts as well as by allowing to switch between keyboard and BBS mode within a session (e.g. Airmail).


Hamnet

Within the Hamnet network DB0NTS is known as db0nts.ampr.org and currently offers AXUDP links for message forwarding partners.

If you are interested in accessing DB0NTS through Hamnet either as a link partner or as a user please contact the station trustee (see below).


Public internet

DB0NTS does not offer direct access over the internet. However, telnet to packet radio gateways may be used to connect the station by packet radio. This works very much the same as indirect HF access (see above).

    user  --internet-->  telnet/ packet  --packet-->  DB0NTS
                         radio gateway

A popular such gateway is DB0FHN. See their website for details.


Others

If you feel the need for additional frequencies, operating times, or services please contact the station trustee Peter Dintelmann (DL4FN).


Manual operation (DF0NTS)

Manual operation is performed under the clubstation callsign DF0NTS. If you are interested in a sked please contact the station trustee (see below). Preferred mode is CW.
