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:
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 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.
Direct HF access
DB0NTS offers the following services to users on HF:
|Time (UTC)|| Frequency
|1000||1300||reserved for future links with Oceania MBOs|
|1400||1930||traffic exchange with US MBOs|
|1400||1900||14097.0||Pactor 1,2||Packet GW||up|
|14108.0||Pactor 1,2,3,4||Winlink RMS||up|
|1900||2100||3591.5||Pactor 1,2||NTSD MBO||up|

|3592.5||Pactor 1,2||NTSD MBO||up|
|3593.0||Pactor 1,2||NTSD MBO||up|

|3594.0||Pactor 1,2||Packet GW||up|
|1900||2100||7047.5||Pactor 1,2||NTSD MBO||down|

|7049.0||Pactor 1,2||NTSD MBO||down|
|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 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 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 DB0FHN *** connected to DB0NTS DB0NTS-2} Connected to BBS [BPQ-220.127.116.11-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). 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 are offered for message forwarding partners both through Hamnet and the public internet.
If you are interested in accessing DB0NTS either through Hamnet or the public internet as a link partner or user please contact the station trustee (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 trustee Peter Dintelmann (DL4FN).
Manual operation (DF0NTS)
Manual operation is performed under the clubstation callsign DF0NTS. This is to interface with traditional phone and CW nets both in Europe and internationally.
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.
