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 DTN/ 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 -- DB0BOS -- DB0NTS
    JN49ma    JN48iv     JN49bh    JN49lr    JN49mp
      |                    |                   |
    DB0KIT               IGATE               DB0FHN

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) when you are located nearby.

Generally, it is recommended to connect through Germany's central packet radio node DB0FHN.

Direct HF access

The following table contains the HF operating plan for DB0NTS. Frequencies used for inter-MBO links are not listed for privacy reasons.

Remarks: The frequencies listed above are centre frequencies.

The Packet Gateway will connect you to Germany's central packet radio node DB0FHN.

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

Note that DB0NTS also runs a packet radio gateway.

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

    *** 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

    *** connected to DB0NTS
    DB0NTS-2} Connected to BBS
    NTS Eastern Area BBS for Europe
    TFC 0 FWD/ 0 DF0NTS
    DF0NTS de DB0NTS> B

    *** reconnected to OE9FWV

    next? Q
    df0nts de oe9fwv>
    *** 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). Users report indirect HF access not to work with BxF forwarding protocols. We therefore recommend to use this type of connection with terminal commands only.

Hamnet and public internet access

AXUDP links for message forwarding partners are offered both through Hamnet and the public internet. If you are interested in accessing DB0NTS either way please contact the sysop (see below).

Additionally, 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.


If you feel the need for additional frequencies, operating times, or services please contact the station sysop (see below).

Manual operation (DF0NTS)

Manual operations are performed under the clubstation callsign DF0NTS. This is to interface with traditional phone and CW nets both in Europe and internationally.

Weekdays Time (UTC) Frq. Band Mode Net/ Station Remarks
Tue 2100 80m CW European stations n/ a
Tue 2030 20m CW WB8WKQ

traffic headed to Oceania; currently paused because of propagation conditions

If you are interested in a sked please contact the station trustee (see below).


The DB0NTS sysop and DF0NTS station trustee Peter Dintelmann (DL4FN) can be contacted by email at dl4fn (atsign) yahoo (dot) com. Please use this email address for sysop related questions only.
