Issued and available UK amateur radio callsigns

We're waiting for Roger Howell to read recent responses and update the status.

Dear Office of Communications,

Please provide a dataset of every valid UK radio amateur callsign, the licence class, and its current issue status (for example but not limited to: allocated, reserved, available, forbidden, otherwise unavailable for a new licence application).

Alternatively, please provide the relevant data that would be enable the derivation of such a dataset. I believe that such data would include at minimum:

1) a list of all valid formats with corresponding licence class,
2) a list of all forbidden suffixes, and
3) a list of all currently reserved/allocated callsigns.

If there are any cases where a callsign meets the valid formats in (1), is not a forbidden callsign (2), and is not reserved/allocated (3) but is still unavailable to be issued, please provide details of the rules and/or restrictions that apply.

Yours faithfully,

Roger Howell

Dear Julia Snape / Jerin John,

Thank you for your helpful and complete reply - the data and the accompanying cover letter is much appreciated.

I have yet to analyse the data fully, though a cursory initial inspection shows that of the 141,295 records:

* There are six records which have a blank status.
* There are 21 records which have callsigns of length of six characters (e.g. where country identifiers have been included inconsistently).
* There are three records which have a trailing non-breaking space in the callsign column.
* There is one record with a space in the middle of the callsign.

While I am happy to inspect and clean the data before analysing further given that these comments relate to only an extremely small minority of records, I raise these to your attention so that you may consider amending/correcting/cleaning the source data.

Finally, would you consider a periodic public release of this data - perhaps monthly, bimonthly, or quarterly?

Yours sincerely,

Roger Howell

Julia Snape, Office of Communications

Im out of the office till Wednesday 11 September with no access to emails.
