IOTA Contest 2022 from EU-005

Date: 30th & 31st July 2022

Contest Callsign: G5O

IOTA: EU-005

Operators: M5KJM, M1PTR, M0TJU, M0DCG, G0LZL, G0SYP and G6RSU

Station Setup:

Run 1 (primarily set for SSB): Yaesu FT5K with Heatherlite Linear. Antennas 20m and 15m monobanders plus 40m delta loop and 80m dipole.

Run 2: Yaesu FT5K and Quadra linear with the TH6, along with 40m and 80m dipoles. The TH6 was supposedly set for midband, primarily for CW but able to operate SSB.

29th July 2022 – Pre-contest musings by Evan M0TJU

I’ve attached a couple of spreadsheets you may be interested in. Sorry they’re a bit late in materialising.

The first, which is really for Pete, is a list of stations for which we know the IOTA references. (The info was acquired through DX Summit IOTA spots and NG3K.) Column A shows the callsigns. To make sure that Wintest detects these stations, I have duplicated stations without “/P,” in case these stations decide to go portable during the contest. For example, I have copied 9A/DM6EE, with the copy being 9A/DM6EE/P. Likewise, for stations spotted with “/P”; the copy is shown without the “/P.” The IOTA refs are show as text in both column B (with hyphen) and column C(without).

Hopefully, you should just be able to copy the callsign/ref information to a file compatible with Wintest. This should help with callsigns which – if Wintest is left to its own devices – will result in false IOTA refs being generated (e.g. GM2T, on EU-008, will be assumed to be EU-005, at least before the contest’s start). Sorry, the ‘European’island group with the ‘AF’ designation are on the bottom of the list.

The other two spreadsheets – one for CW and the other for SSB – allow you to track how well we’re doing with working IOTAs to particular regions of Europe on certain bands. The station manager, having clicked into the ‘Input’ tab of the spreadsheet, can put a ‘1’ next in the cell relating to a IOTA/band combination once it’s been worked, and see it reflected in the second tab (showing the Eu regions). Note that some of the IOTA refs on the second tab are bold; this is to highlight the IOTAs which will likely be activated during the contest. (Unfortunately, the likely mode/s to be used by stations activating the island groups was not recorded, so that the same bolded references showing on the SSB spreadsheet match those on the CW one.)

Regarding station operation, solar flux of below 100 and geomagnetic instability will make for pretty ordinary conditions, especially on SSB. Re Eu locations, 10m will likely only be open F2 to the eastern Med and the Atlantic Iberian islands (e.g. EA8); sporadic E will be needed get into the western Med on 10m, although, unlike at Arranmore, this region is in single-hop Es range from our QTH.

When operating, keep an ear out for any non-standard (‘anomalous’) propagation, and work the IOTA mults using that propagation mode (e.g. work GM2T when you can hear it on 14MHz and up) before the prop disappears. Daytime anomalous prop modes for each of the regions are:


UK/Eire, North Sea, Channel Is/Biscay: 14MHz and up.

N. Scandi/Russia, Baltic, W. Med: 21, 28MHz

E. Med: 28MHz

I would make use of the new ‘Main’ of the RBN website, click ‘Advanced Mode’ (centre-right), select max rows ‘100,’select Continent ‘EU’ under both the ‘Spotter (de)’ and ‘Spotted (dx), and click the ‘CW’ box. Then, click the band that you want to find the contacts for. (I would open three windows, one for the 20m, 15m and 10m bands.)

This will enable you to see who is working who, and if there are any sporadic E clouds over the continent.
Don’t forget North America, where IOTA is increasingly popular: 30 NA IOTAs have been identified as active, so swing the beams west, especially on 20m late in the afternoon and into the evening.
