• Added call to clear_filter_display for A2B and B2A functions.
• Corrected FM and AM MON functions.

Download 2.037j

• Modified AGC system. Now has slow attack to eliminate hang-up on spikes.
• Lowered Line-Out level because it was clipping in version 2.034.

• Modified the Serial Port Baud Rate Timing for more accurate 57600 Baud Rate.
• Modified TUNE function. The main receiver was incorrectly changing to the sub receiver mode when tune

was pressed and the main and sub receivers were both assigned to VFOB.

• Added ALC LED Hang to provide better visual feedback of ALC action
• Modified VOX. Now forcing VOX to OFF state when mode is updated to prevent false triggering when entering CW modes.
• Modified SPOT and SIDETONE scaling to eliminate line-out overload.

• Modified the AM Carrier adjustment to eliminate downward modulation.
• Added menu item and control for MIC channel PGA through the DSP. Located in SSB Menu
• Fixed FM/AM monitor distortion.
• Added test for MIC PGA in power-up function so users don’t have to reset radio after update.
• Corrected bug in external band and A/B, A>B operation that could cause incorrect band lines to be output.

• Changed Voice Record system. Monitor now OFF during record unless the user has MON turned on.
• Added recall of preset antenna selection to the serial frequency set routine.
• Modified AGC for AM RX because it was causing distortion.
• Added on-screen SPLIT annunciator.
• Added on-screen BAND REGISTER indicator (A,B,C,D)
• Modified TGC for AM transmit to correct carrier level control.
• Added FM mic limiter to prevent over-deviation.
• Increased BW limit to 9khz for improved am rx
• Added ULcc<cr> code to the serial command structure to control the line-out selection and level.
• Added UL? Query to the serial command set,
• Fixed the sub S-Meter display and SQL operation that caused meter to disappear.
• Scaled FM and AM audio levels to get more output on speaker and rear panel outputs.

• Corrected bug that caused VOX to turn off on a band change.
