The VHF / UHF Listing is a list of the call-signs of stations with a checked score of 100 or more IOTA groups on the VHF / UHF bands.

Listing in the 2017 tables was restricted to those participants who had updated their scores since February 2012. IOTA rules limit inclusion in the listings to those participants who have updated their scores at least once in the preceding five years and have opted to have their scores published.

All participants should be reminded that the final decision on acceptance of credits is made at IOTA HQ and that this can mean downward adjustments to scores at any time to reflect corrections of one sort or another. Data-cleansing work is on-going and covers every participant's complete record, not just the latest credits added. Although efforts are made to alert participants to score changes, this cannot be guaranteed to happen in each case.

Remember, the line of communication is via your checkpoint, so PLEASE do not route queries direct to IOTA HQ or the IOTA Manager. Always check first to see if the answer is in a recent IOTA Directory (2014 or 2016 edition).
