I've read all about obtaining a vanity call sign but I'm still unclear about something. Let's say I have five that I'd like to submit. Sign #1 is available on Monday, Sign #2 is available on Tuesday, etc. If I don't get Sign #1, do I have to start all over, or will they just consider my request for Sign #2 the following day and the others each day after that? If not, it doesn't make sense to submit up to 25 since most signs are available on different days, but I couldn't see where it says that. Thanks.
sign#1 is available on Monday, and sign#2 is available on Tues. If you apply on Monday for a sign available on Tuesday, your application for the Tuesday sign will be denied. If you apply on Tuesday for both of those signs (and if the Monday sign is still available three weeks from Tues) then you will get a shot at each of them.
There is about a three week wait between application and when they run "the lottery". This gives folks 10 days to get their payment in (by mail). If neither of these are sought-after callsigns, then applying on Tues for both signs will probably give you a shot at both signs. If there is competition for the callsigns, then you would have to apply on Monday for sign#1 and then on Tues for sign#2. Three weeks later, if you get your Monday callsign then you can go in and cancel your request for sign#2. If you FAIL to get sign#1, then you may request your fee back for that attempt, and then wait and see what happens with sign#2. If that one fails, you make a request for THAT fee back.
Your list of up to 25 callsigns need to be callsigns that are available ON THE APPLICATION DAY. choosing callsigns available before that day (often taken by the time of the lottery) or after that day (automatically disqualified) doesn't work.
Again, remember that you can petition for the return of your fee if no callsign is assigned. Thus, it costs you nothing to apply. Further, you have up to 10 days to pay the fee. You can monitor the progress of that callsign. If it looks like 100 people have applied for the same callsign, you can just not pay and you will be automatically removed.
Generally, the ONLY way to get a coveted 1x2 or 2x1 callsign is to apply ON THE DAY that it becomes available. You will find some 2x1 callsigns that aren't so coveted that are always available, but they usually have weird or quirky letter combos that people shy away from.
You did not say what type of callsign you are going for. For me, I created a list (of 1x2 and 2x1 and 2x3) by examining each area, determining which callsigns are coming up over the next couple of months, and making a list of the day/callsigns that I would apply for. On the day that I applied, ND8K was my fourth choice, and there was NO competition for it (actually, there was competition at first, but as people dropped out due to non payment, it opened up free and clear after my first three choices were taken.)
clear as mud?
Finally, all entries from Sat/Sun/Mon go into one drawing. There is generally much more competition for callsigns that come up over the weekend.
