v1.26.1001.1
Released 2026-03-23
Stable Download
New & Improved
  • New Feature - Power Up/Down Control . Amplifier and Tuner can now be configured to power up when an SDR client connects, and power down with a configurable delay after client disconnects. Also power up sequences can be completely disabled. (It will be on you to turn them on) Or you may choose existing behavior of power up when Plugin loads. (Basically always on)
    • Power Behavior
  • New Feature - Device Control Window in Controller. A new floating window has been added for direct control of the KPA1500, KPA500 and KAT500. Panels are visible based on enabled Plug-ins. Front panel actions have been replicated for access to options like changing modes, antenna ports and monitoring for faults. Stays on top, and remembers position and layout. The labels are clickable and perform the direct action to the device. Click the "↔" or "↕" to swap layout. Drag the window with "≡"

    • Horizontal Device Control Device Control Horiz
    Vertical Device Control Device Control Vert
  • The Meters window has been enhanced for better readability. Hash marks with values provide scale for readings.
    • Meter bars hash
Bug Fixes
  • Controller - When the Autostart option is unchecked, when host machine is rebooted, PgTgController menus were disabled. This has been resolved.
  • An edge-case bug has been resolved that could cause the PgTgBridge Service to not correctly identify the correct Ethernet interface. The IP address was defaulting to localhost.
v1.26.999.1
Released 2026-03-17
Beta Download
New & Improved
  • Controller - When hovering over the tray icon, the popup balloon help text now indicates the radio nickname it is configured for.
Bug Fixes
  • Plugin - Air Monitor plugin was not sending correct command syntax. It was prefixing "$" to all commands. (CAT mode tested and is fully working. Icom CI-V mode not tested yet)
  • Clarification - The key amplifier during radio tune carrier option is only applicable when PgTg is controlling PTT over the Network or by GPIO plugin. If you have an RCA cable connected from the radio TX1-3 to the amplifier PTT input, PgTg cannot execute this option!
v1.26.996.1
Released 2026-03-14 (Happy Pi Day!)
Beta Download
New & Improved
  • PgTgBridge resource management process improved. Shutdown steps are now sequenced in preferred order.
  • Controller - Pops up reminder if you try to launch it from the shortcut twice.
  • Plugin for Air Monitor added — Allows another radio to track the transmit frequency and mode for monitoring your transmitter. Serial, TCP, CAT and CI-V supported!
  • Plugin SDK public interface tested — Air Monitor is compiled using the public interface. Binary DLL included in deployment.
  • Plugin SDK sample projects published on GitHub including fully implemented SampleAirMonitor project.
  • Plugin Manager - External Plugins can now define which options are displayed when selected.
  • Plugin Manager - Master/Detail layout changed to over/under style. Provides more room for plugin options. Yes, you can configure your KPA500 and KAT500 to be accessible via TCP. See PgTgBridge Installation Guide.
    • Plugin Manager
Bug Fixes
  • Plugin Manager - Plugins now can have your own version numbering. PgTg will now load them by name only.
  • KPA1500 / KPA500 - The internal plugins for these amplifers now enforce the minimum firmware version required for PTT over Network mode. If not sufficient, PgTg will disable the option for PTT over Network to avoid Interlock errors from radio.
  • Clarification - The key amplifier during radio tune carrier option is only applicable when PgTg is controlling PTT over the Network or by GPIO plugin. If you have an RCA cable connected from the radio TX1-3 to the amplifier PTT input, PgTg cannot execute this option!
v1.26.984.1
Released 2026-03-10
Beta
New & Improved
  • No new feature changes in this build.
  • Behavior change - The initial value for the "Key amplifer during radio Tune Carrier" has been changed to Unchecked".
Bug Fixes
  • Fixed button action assigned to Operate button in SSDR Tuner panel. The button was not staying in synchronization with the TUN icon/button on Task Bar.
  • Refactored reconnection logic to properly restablish connection to the radio when the radio is power cycled.
  • Fixed a bug in the About Box that caused the remaining trial day counter to not accurately display the correct value.
  • Removed some extraneous log entries relating to calculated KAT500 power values.
v1.26.983.1
Released 2026-03-07
Beta
New & Improved
  • Promoted to public release — Build #983 milestone achieved after multi-station beta testing.
  • Band-change propagation is now fully automatic for all supported radios and hardware combinations.
  • Band-specific Operate/Standby power control — each band can have an independent power limit and operate mode behavior.
  • FlexRadio Aurora™ series support included (beta designation, see Aurora news post).
  • Tray meter panel now reports Forward Power (W), SWR, and Amplifier Temperature with live refresh.
Bug Fixes
  • Fixed rare race condition where band-change message could arrive before amplifier serial port was ready, causing a missed transition.
  • Fixed tray application not reflecting service stopped state after a Windows restart.
  • Fixed KPA1500 SWR meter returning zero on first read after service start.
