After extensive beta testing across many stations, PgTgBridge Build #983 is officially released. This stable build supports all FLEX-6000/8000 series radios paired with KPA1500, KPA500, and KAT500 hardware with automatic band-change propagation plus band specific Operate/Standby power control.

Hardware Support

Build 983 is the culmination of real-world testing at multiple stations running a variety of FLEX-6000 and FLEX-8000 series radios in combination with Elecraft amplifiers and tuners. The following hardware combinations have been validated:

• FLEX-6000/8000 series + KPA1500 amplifier
• FLEX-6000/8000 series + KPA500 amplifier
• FLEX-6000/8000 series + KAT500 antenna tuner
• Combined KPA500 + KAT500 configurations

Upgrade Notes

Users running earlier beta builds should upgrade to this stable release. The Windows Service installer handles migration automatically. No manual configuration changes are required.

The PgTg Plugin SDK documentation is now live. C# developers can create custom amplifier and tuner plugins using the same public interfaces used by PgTgBridge internally. Full API reference and sample projects are included.

Public Interfaces

The Plugin SDK exposes the same interfaces that PgTgBridge uses for all of its own internal hardware support. Third-party plugins are first-class citizens — they load, configure, and communicate using exactly the same mechanisms as built-in plugins.

• IAmpPlugin — amplifier control interface
• ITunerPlugin — tuner control and tune-cycle interface
• IPluginHost — access to band data, PTT state, and settings
• Projects reference the actual deployed assemblies so PgTgBridge must be installed on the development workstation. (You can Start/Stop the Service to reload your development plugin DLL.)

Sample Projects

Visual Studio C# sample projects cover patterns required to create a compatible PgTgBrige plugin. Verbose inline documentation explains each interface method and its expected behavior.

PgTg now includes support for the FlexRadio Aurora™ series. Though using an external amplifier with Aurora series is not needed, testing confirms PgTg operation with Aurora radios can be leveraged to control a tuner such as the KAT500 in a remote location.

Remote Tuner Use Case

While the Aurora™ series includes an internal amplifier, there is a compelling remote use case: placing a KAT500 at the antenna feedpoint and using PgTg to command tune cycles and band changes automatically as you operate. PgTg handles all band-change signaling between the Aurora radio and the remote tuner without requiring manual intervention.

Beta Status

Aurora support is included in the current release build but is designated beta pending broader field testing. All core functionality — band-change propagation, tune-cycle initiation, and meter reporting — operates as expected in lab testing. Operators using this configuration are encouraged to report any issues.
