Here is a message from Petr, OK2CQR (#92), who is the author and 
maintainer of hamqth.com callbook server:
--------------------------------------------------
HamQTH.com started 6 moths ago. Information about new free ham radio 
call book was published on 29 of June 2011. When it started we had a few 
problems with old records for many US stations. I did a mistake in 
script that imported data from FCC database. Fortunately, I fixed the 
problem soon.

After call book got public, I got a lot of databases from users, who 
like the idea of HamQTH, and imported it. Thank to them, the database 
had more than 1 300 000 call signs. Great! Thank you! A month or so 
later, I created XML access for logging programs. First log, that used 
it was DFHLog from Jesus, EA7DFH. He was faster than me! After DHFLog, 
XML search supported also CQRLOG. Not so many programs, but it was the 
beginning.

After another month I added Google map support. It works very well and 
location is calculated from station address, not from grid square. 
Sometimes it didn’t find the address and it would be great to point 
location from grid square. It is on my todo list. Also it should 
calculate missing grid from position pointed by Google from address. 
Also on my todo list, please stay tuned. Thanks to map position, HamQTH 
calculate azimuth and distance between you and the station and the 
sunrise/sunset as well. Also more programs implemented XML lookup e.g. 
LuxLog, WinEQF. I moved the database to another faster server. Web 
stayed on it’s original location.

Another great feature I added a few weeks later - Recent activity. I 
wrote small program which is connected to RBN and DX cluster and 
collects all spots. I must say, it is a lot of spots! During CW WW CW 
program collected over 2.5 million of spots from RBN and DX cluster. I 
save only recent 100 spots for every station. Older spots are deleted. 
Right now, the database has over 2.7 million records and the number is 
growing. I believe that a lot of records will be wrong calls but I can’t 
delete it, I don’t know which are wrong. With Recent activity function I 
also modified the website and all texts can be translated into other 
languages. Today, website is translated into 13 languages.

On the beginning of October I created special ADIF interface for 
Logger32, added prg parameter to XML search and implemented internal XML 
search statistics. Since then other logs add XML search support for 
HamQTH e.g. Fldigi, UR5EQF log, MaxLoggerDX, RUM log etc.

On December I moved also website to faster server together with database 
which is growing very fast. Also added new function - log search. You 
can import your log, specify which fields and statistics will be visible 
and other users can use it.

XML statistic has many records. On the top is UR5EQF Log with almost 
62000 requests, the second is Logger32 with almost 49000 requests, the 
third is HamReference. Together since 7th of October there has been over 
268000 requests to XML search. After 6 months on line we had over 72000 
visitors, almost 500000 page views and 6152 registered users.
------------------------------------------
New facilities (ie. VOACAP propagation prediction) to be added later, 
stay tuned!

P.S. We are looking for any bigger DXpedition which is in need of an 
online log. Hamqth.com is very fast, reliable and accurate.
