During December 2021 OE5TXF logged his 80,000th QSO from Upper Austria

Band vs Mode

The table below shows the breakdown of the 80,000 OE5TXF QSOs, both by Band and by Mode.

The highest number of QSOs (22,657) were made on 80m and the most used mode was FT8 (41,233 QSOs) followed by CW (28,464 QSOs).

Contest vs Non-Contest

Analysing the 80,000 QSOs by "Contest" vs "Non-Contest" shows that 47% of QSOs (37,601) were made in Contests and that 53% of QSOs (42,399) were made outside Contests. The table below shows both the split between "Contest" and "Non-Contest" QSOs, as well as the QSO numbers split by mode.

6m 91 892 983 9.3%
Totals 37,601 41,399 80,000 47.0%

The two bands with the highest percentages of Contest QSOs are 80m (74.0%) and 40m (60.1%). The large number of RSGB Contests on 80m contributes to the high percentage of Contest QSOs on this band.

The band with the lowest percentage of Contest QSOs (excluding WARC) was 6m with just 9.3% Contest QSOs.

 

Continental Breakdown

Unsurprisingly Europe is the Continent providing the largest number of QSOs. The relatively restricted antennas at OE5TXF (all low wire-dipoles, no towers or beams!) combined with the continuing subdued HF propagation conditions, results in there being a high percentage (84.0%) of EU stations in the log.

Continent QSOs %
EU 67,201 84.0%
NA 6,119 7.6%
AS 4,773 6.0%
AF 762 1.0%
SA 664 0.8%
OC 477 0.6%
AN 4 0.0%
Totals 80,000 100.0%

 

Unique QSOs

Given that a large proportion of the 80,000 QSOs are Contest QSOs where traditionally we work many of the same Callsigns "over and over again", it is not surprising that there are a large number of "Callsign Duplicates" in these 80,000 QSOs. Nevertheless there are 27,192 Unique Callsigns (34%) in the amongst the 80,000 QSOs made by OE5TXF up until mid December 2021.

 

DXCC Challenge

OE5TXF logs are regularly up-loaded to LoTW to track the DXCC Challenge score (currently 1,351 worked).
