    • Version 4.2 (Mar 02, 2023)

  • Windows x64 package now contains an updater script that can be used to update to the latest available version in just a few seconds, without loosing any previous application configuration.
  • two install/update scripts are now available for linux (Debian flafour). One use java11, the other java17. Use the one that works best for you.
  • new audio library (both UDP and TCP audio).
  • audio over TCP supported in v3 compatibility mode too (to be used with Pocket RxTx v3.4 and up).
  • Network audio mode (UDP or TCP) is shown on the configuration page in both Server modes.
  • Audio loopback is shown on the configuration mode in Both Server and in Client modes.
  • central repository copy (from the compilation date) stored in the application (to be used if no Internet access or when central repository is not available).

  • app crash when minimized, if installed using the script.

    • Version 4.1.1 (Feb 03, 2023)

    Solved bugs:
  • for some radioa (ex. FT8x7), can't set frequencies below 10MHz in SRV-v3 mode).

    • Version 4.1 (Jan 29, 2023)

  • Waterfall support added for IC7300 and IC705 (limitations: when waterfall active, only FREQ, MODE and FLT are updated in the GUI when changed directly on the radio).
  • use mouse scroll wheel to adjust frequency (+/- 10Hz step, +/-100Hz step if CTRL key pressed in the same time, always 1KHz in FAST mode.
  • auto info support added (for the transceivers that can auto transmit parameter value when changed. For CI-V only FREQ, MODE and FLT are transmitted, for some Yaesu models (ex. FT450) all parameters value are automatically returned when changed directly on the radio (including meters), so continuos polling is no more required.
  • Band/Pref Mode label has now a dedicated position in the top of frequency display.
  • first 5 fixed labels (TXPWR,SQUELCH,MODE,VFO,AGC) are now considered standard labels, so must be present in the LSTLABELS definition, in the position you want them to be.
  • Squelch status (SQLSTAT), if available through CAT, is now represented by the text color of the SQUELCH label (Green = OPEN, Red = CLOSE).
  • prevent sending TUNE command if ATU=OFF.
  • TUNE button text changed to "TUNING..." during the tuning process.
  • ATU parameter has only 2 values in the GUI, as TUNE is assigned to the dedicated button.
  • when you click on ScanSWR menu item, scan does no more start automatically, you must press PLAY icon.
  • added user configurable number of steps (AUTO, 10, 20, 30, 50, 100) for SWR scan, to beter suit your needs.
  • added a checkbox in the SWR Window, for "QSY in Tx". When checked, frequency is changed during scan without going to Rx first. This was the usual behavior in the previous jAReC version, but not supported by many radios (ex. FT450, FT817, etc). The dafult is with QSY in Tx deactivated (longer scan duration).
  • added the option to scan SWR only +/-20KHz from the tuned frequency. This can be useful for MagLoops, with a very narrow bandwidth.
  • tuning knob can now be rotated using touch type gesture, not only the mouse croll wheel.
  • accept hex digits in and tags, not only from 0 to 9 (ex. , , .
  • windows positions are now saved when you close the application.
  • tuner menu now active in client mode (only for SWR scan).

  • when disconnecting from the server in client mode, do no more return to the startup window.
  • you can now just keep the mouse on top of a label (without vclicking on it) and use scroll wheel to adjust that parameter.
  • keyer is now working in client mode too.
  • to change a parameter value with the mouse wheel, you can now to just keep the mouse over that parameter and use the scroll wheel, without clicking on the parameter.
  • Mute is activated when SQLSTAT = CLOSE (as usually audio over USB is not stopped when squelch activated)
  • use separators to better represent hex and bin data in Cfg Builder.
  • add data length for received hex and bin data in CfgBuilder.
  • in CfgBuilder, do not automatically poll all parameters when connecting if not in PANEL mode.
  • profiles are now ordered in alphabetical ordered in the list.
  • Tuner menu moved from server to client.
  • frequency is rounded according to the tunning step.
  • "Returned value" changed to "Decoded data" in the CfgBuilder.
  • change menu behavior (menu items are no more hidden when not available, but disabled).
  • PTT and CW KEY mode settings in the GUI changed.
  • filter only letters and numbers in the Keyer macro definitions and force capitals.
  • Audio Loopback available in v3 compatibility mode too.
    • Solved bugs:
  • audio not working for Tx in server mode (both native or v3 compatibility).
  • click not active on the full surface for the buttons: Down, Up, Tune and Fast.
  • error if patterns defined for string type parameters (like FT991) with more than 1 char (ex. ,{VFO:VFO-A=;VFO-B=;},...
  • IP address/hostname of the remote server not saved in client mode.
  • radio panel menu not visible in client mode.

  • changed values for the METERSEL parameter to ALCMTR, MODMTR,VLTMTR,PWRMTR,SWRMTR and SMTR.
  • debug mode automatically disabled when you restart the application.
  • raw meter value displayed in the lower left part of the meter. Can help to set meter calibration in the radio config.
  • audio over TCP option in CLI or SRV modes (selectable from the Settings menu.
  • bat file instead of exe to launch jAReC from the Windows packaged version, to prevent false positive reports from some antivirus applications.
    • Solved bugs:,
