Winlink
via HB9AK using RPR on HF

Daylight ☀     Center Frequency 10145.900 kHz USB   DIAL 10144.400 kHz USB *
*verify changes by updating frequency tables of RMS Express

What hardware do I need?
The operation can be done with the SCS Tracker only !
Of course PTC-IIIusb and older PTCs that are equipped with a DSP-Modul can do it as well.

Which program can do the Winlink connection by RPR?
In this demonstration RMS Express is shown. It can be downloaded from the Winlink website RMS Express . In the FTP folder of Gregory R. Hand find the ITS HF Propagation Program (latest version 14NOV14) and install it first. It provides condition forecasts within the station selection area of RMS Express (very smart !)

Do I need a valid Winlink address?
Yes.


See the following example with a Kenwood TS-480, SCS-Tracker & RMS Express

Frequency selection has to be done manually or you may put a memory like in this example. The DIAL frequency is taken from the RMS Express table. USB of course.


Open RMS Express and select Robust PR WL2K. Press Open Session followed by Channel Selection and verify conditions forecasted. For Europe HB9AK is the only station.
If no stations are show press Update Table while connected to the internet and the complete list (incl. PACTOR frequencies) will be updated.




In order to have a positiv initialization you have to make the setup for TNC and Radio. As usual be careful with the Transmit Level. Check that max ALC level is not exceeded.






When setup and channel selection is done press Start on the Robust PR Winlink 2000 Session window. RMS Express will connect Winlink via HB9AK and look for your emails in the system.
The tracker meanwhile shows in the first place 2 green LEDs indicating the connect status followed by the alternating rhythm of red LEDs RDCD & RPTT marking the exchange of the packets.







After successful exchange the program looks like this




The RPR email exchange works as well as Peer-to-Peer connection. It is then not a kind of chat room but again a possibility to ask for MY emails kept in the OUT BOX of the peer's station.
In that case the emails must have been compiled as PEER-to-PEER mail (see selection in the header of RMS Express ⇒ Message ⇒ New Message window) plus both peers must have the window Robust PR P2P open. Then you may start the peer-to-peer connection any time convenient.

So for once the Tracker is not reduced to work as stand alone position sending device or the KISS slave of an APRS program. It is fun to see the SCS Tracker working like the big PACTOR brothers. By the way: if the conditions are excellent you may see it jumping automatically to R600 speed. This will then turn RDCD and RPTT normally red (R300) LEDs to continue in green color.

Enjoy!
