TQSL will enable you to obtain a Callsign Certificate that identifies you as the source of the QSOs you submit, and will also enable you to define a Station Location that specifies the geographical details of your operating location. A flowchart illustrating these steps is available here. The postcard will specify an 8-digit "postcard password"; using your web browser, navigate here , and type in your "postcard password". Thus you should contact an in-country Card Checker in advance to ask if they are willing to check your identity and license documents.
Next, define a Station Location that describes the location from which you operate using your current callsign. Skip to content.

Heightened demand has led to a number of innovations geared toward improved spectrum efficiency , including dynamic spectrum management , trunked radio, frequency pooling, spread spectrum, cognitive radio and ultra-wideband.
A cellular network typically covers a specific geographical area divided into cells. Every cell is allocated a set of frequencies that have radio base stations assigned to them.
When a communication such as a cellular phone call is initiated, the device searches for the closest base station to establish a radio link. When receiving the call, the base station antenna establishes a connection with the phone.
Phones are designed to periodically check in with the network, making it easier for them to receive a radio signal of substantial quality from a nearby base station antenna. RF technology allows a set of frequencies to be used in other cells, as long as the cells aren't bordering each other. It is possible for numerous callers in one area to use the same frequency because calls can be switched to the closest base station with that particular frequency. This increases the capacity of the cellular network.
However, the frequency reuse works only for unrelated transmissions. Users can still experience some interference from signals coming from other cells using the same frequency. This is why wireless networks use a system of frequency-division multiple access FDMA , in which there must be at least one cell in between cells reusing the same frequency.
FDMA enables numerous users to send and receive data through the same communication channel. Cellular network users can also move from one cell to another while calling, without calls being dropped. Through the handover process, the mobile device remains aware of signal quality and the nearest antenna with the least congestion. When need be, the mobile device switches to a new and more convenient channel.
Wireless 5G -enabled devices connect to the internet and telephone networks using radio waves that go through a nearby antenna. As the upcoming iteration of wireless broadband network technology, 5G provides peak speeds as high as 10 gigabits per second Gbps for downloads.
Bug fix: Stations showing up in weird positions Germany, Faroe Islands as a result of localization. Handle commas for decimal separation correctly on computer that require it.
Fixed some protocol issues that some implementations of KISS didn't like. My bad. Made some incorrect assumptions when configuring the serial port.
See the Quick Start guide for more info. Includes support for overlays. This section is for testing of new versions that are not considered stable yet and are actively being updated with bug fixes and enhancements.
