Subject: POTA/SOTA DXCluster

Scott hi

Maybe it would be interesting for users of your programme to improve the reception of telnet DXCluster spots for interested group of users of POTA and SOTA programme. On the S50CLX DXCluster I have implemented the integration of spots that are not part of the classical telnet DXCluster network. More in my note below. The user of your programme would thus have the possibility to select in the programme the reception of specific spots via a button, with predefined commands to be sent to the S50CLX DXCluster after a successful connection. Sorting, searching by reference ... etc is a matter of implementing such spots into N3FJP software. The idea for the buttons is:

1. POTA ONLY spots -> command executed: ACC/SPOTS INFO -POTA-

2. SOTA ONLY spots -> command executed: ACC/SPOTS INFO -SOTA-

3. BOTH POTA&SOTA spots -> command executed: ACC/SPOTS INFO -POTA- OR INFO -SOTA-

4. S50CLX CLUSTER DEFAULT (all spots) -> command executed: CLEAR/SPOTS ALL

A connection via telnet protocol to S50CLX? which is a completely free service is required to receive POTA/SOTA spots.

Good luck,

73s Dan S50U

POTA and SOTA enthusiasts!

POTA (Parks On The Air) and SOTA (Summits On The Air) are internationally renowned programmes. They encourage licensed radio amateurs to operate outdoors in nature parks or on mountain peaks. Operators making contacts in parks or on summits are called activators, and the other operators who contact them are hunters.

On the S50CLX telnet DXCluster I implemented the collection of spots from POTA and SOTA that are not part of the classical telnet DXCluster network (potaapp and sotawatch). Such spots are tagged with [-POTA-] and [-SOTA-] respectively. In the comment field a spot tagged as such carries:

POTA:
- International POTA reference number, example: SI-0831
- Mode of operation, example: CW
- POTA reference name, example: Preval Vrh Ravni

SOTA:
- International SOTA peak reference number; example: S5/CP-002
- Mode of operation; example: SSB
- SOTA summit name, altitude, points; example: Porezen, 1630m, 8 points

With the right settings, the exact DX spots you want can be received and this is achieved using the filters below. To change an existing filter, simply overwrite it with a new command. Each command (BOLD formatted text) must be entered on a new line, confirm the entry by pressing ENTER.

- for receiving only POTA spots, command: ACC/SPOTS INFO -POTA-

- for receive only SOTA spots, command: ACC/SPOTS INFO -SOTA-

- for receiving POTA and SOTA spots, command: ACC/SPOTS INFO -POTA- OR INFO -SOTA-

The CLEAR/SPOTS ALL command removes all set filters and the S50CLX passes us all SOTA, POTA, DXCluster and optionally RBN (SET/SKIMMER <mode>) spots.

In cases where you do not want to receive POTA and SOTA spots e.g. in a contests, use the command as the first filter before all others REJ/SPOTS 1 INFO -POTA- OR INFO -SOTA-

Spot forwarding is based on the DXSpider DXCluster software validation and normalisation algorithm, rejecting duplicates spots and ensuring quality spots in the face of increasingly frequent malicious attacks on global amateur radio DXCluster network.

The S50CLX DXCluster can be reached via telnet at: port 41112

My small contribution to the promotion of outdoor activities in POTA and SOTA hamradio programmes. :-)
