It would appear that the IP address used for sending emails of my hosting provider has been black listed. As a result I am unable to send emails. I am able to receive them. I have contacted my hosting provider and they are telling me that the issue should be resolved within the next 24 to 48 hours. Until then any of the web pages that send emails, such as creating an account or changing email addresses, will not work and if you send me an email I will not be able to respond. I apologize for the inconvenience.

Call Sign Lookup
You can use this lookup to search RadioQTH's database of call signs. The data is a day
or two behind the FCC's data so some calls might have been assigned and yet still show as
inactive or not show up here at all. For the latest up-to-date information you can search
the FCC's live data by clicking here.
For the RadioQTH lookup below, once the results come back you can click on the call sign
and get a detailed listing of the call holder's license data. While the call holder's data
is showing you can click on the License ID field and get a history of that specific call holder's license.
If you would like to do a more advanced license call sign lookup, where you can list
amateur radio operators by their zip code, then please use the Zip Code Lookup
feature by clicking here.
