Band specific DXCC hunting using software tooling revealed A new way of hunting DXCC’s using Software tools Author: Cornelis van Zuilen, PA7TWO – M5TWOv0.4
index • About PA7TWO • The problem • Background information • DXCC hunting solutions used up to now • The test prototype setup • Testing the use-case • How to setup the tools • Some results! • Credits page • Addendum
about pa7two • Licenced since 1991 as PD0RCJ = VHF LP DX in FM only • Upgraded to HAREC I in 1991 as PE1OOY = VHF + 50MHz HP DX in SSB/FM • Won several contests 50MHz over the years. Also 144MHz in QRP. DX IS! • Changed Dutch callsign into vanity PE7TWO in 1997 • Obtained British callsign G7TWO in 1997, MNI TNX to G1EUC (RIP my friend) • Passed CW exam in England in late 2000, got HAREC A/B certificate. CW IS! • Obtained British vanity callsign M5TWO one week after passing CW exam(!) • A 3 full months later(!), Agentschap-Telecom issued PA7TWO based on HAREC • Dec 2000 = My 1st HF QSO’s in log (do you remember the UFB propagation?) Thehunt for HFDXCCs began!
Background Information • What initiated the hunt for software tooling? • New DXCC scores slowed down dramatically over the last years as they are running out! • Which tools were used up to now to score new DXCC’s? • Operating practice! • Elementary CW code! • Search & Pound! • DXClusters • CW esDiGi mode Skimmers • Internet tools like propagation prediction VOACAP and the knowledge on how to use these • Remote RX station
A few words on the digi Mode FT8 on HF I • FT-8 mode: • When FT8, jointly developed by Joe Taylor (K1JT) and Steve Franke (K9AN), was announced it was described as being designed for, “multi-hop Es where signals may be weak and fading, openings may be short, and you want fast completion of reliable, confirmable QSO’s.” • Being a 6 meter fan, that resonates with me! FT8 mode explained = The new FT8 mode leads!
A few words on the digi Modes usage world-wide on HF II Bye bye digi modes like PSk-31 & RTTY in daily operational mode... Depicted is the mix in modes used on HF bands in 2017 / 2018 = The new FT8 mode leads!
A few words on the current solar cycle 24 Solar cycle 24 = an all-time low?
The test Prototype setup Hardware tools needed are: • TRX (1 or more!) + low band filters • Laptop i5, 16GB mem, 250GB SSD, Win10 0x64 • Mobile, either i-Phone or Android Software tools needed are: • Clublog • HamAlert & HamSpots • WSJT-X or JTDX (In FT8 mode) • JTAlertX • Time Fudge (manual) & Dimension 4 (auto sync) Note: All SW tools discussed are free of charge!
Testing The use-case IUsing the new FT-8 mode • Procedure: • Switch on TRX and laptop • Start WSJT-X • Select FT8 mode • Start JTAlert (version X) • Make sure “Send spots to HamSpots.net” feature is enabled in JTAlert tool • Set proper filters in HamAlert Web. Pay attention to correct settings! • Open HamAlert app on mobile • Simulate DX spot to test the setup (see next pages for details)
Testing The use-case III • Procedure for FT-8 mode: • TRX receives the frequency spectrum • WSJT-X Decodes the FT8 signals received by TRX and feeds these details to JTAlert (which on its turn filters on new DXCC’s / BandSlots) • JTAlert spots the new DXCC / BandSlot and depicts to user • JTAlert uploads spot to HamSpots • HamAlert app receives DXCC/band/mode from HamSpots • Result: ALARM! (That is, if you set your filters correct in HamAlert!) • Advice: Pay close attention to correct filter settings!
Testing the use-case IVHamalert input sources • HamAlert tool alerts were tested using the following modes: • FT-8 via your own TRX > WSJT-X > JTalertX > HamSpots > HamAlert • Alternatively, modes CW, SSB and DiGi like RTYY es JT65 based on spots from other HAMs • Input sources for HamAlert tool are: • DXclusters (including CW Skimmers), SOTAwatch, RemoteBeaconNetwork, HamSpots and PSK Reporter spots
setup The use-case, part I Here the Decoded FT-8 signals are displayed in WSJT-X
setup The use-case, part IIDoes the JT-Alert tool show decodeD DXCC’s? Check to Make sure Decoded FT-8 spots are displayed in Jt-alert, fed by WSJT-X
setup The use-case, part III Check whether your Decoded spots are now displayed here too!
setup The use-case, part IV set correct filters, way of spot delivery, QSL status, spotter callsign etc
setup The use-case, part V Simulate a Specific Decoded spot in hamalert mobile app !enable sound!
setup The use-case, part VI My 1st Self Decoded spot in HamAlert mobile app** enable sound! **
setup The use-case, part VII JT-Alert-can be used for QSO (confirmation) messages RX-ed from DX Station *Yes*, 1st initial test succeeded! New DXCC on 80m band 03-02-2019 FK8CE - QTH=New Caledonia - 16.285KM distance
Final Results • Weekly one or two new DXCC slots! • Didthe new setup solve my problem for working the last few DXCC’s? • YES, THE WAY TO GO! • See next pages for a few new DXCC slots examples spotted by PA7TWO usingthe final HamAlert filter design / setup.
a few DXCC slots are still missing... But A few of these White spots got filled!See Next slides...
