5. Add bluetooth SPP, virtual serial port for FLRIG, Omni-Rig or other CI-V based software
6. Fix the Fc marker bug in modem mode (there will be two markers in the audio FFT scope in some cases)
7. Optimize the fw updating process via sd card, the user data (configures, voices, channels) will not be cleared after updating
8. Some adjustments of the main window
8.1 Add LOCAL TIME / UTC TIME widget
8.2 Add RIT / XIT widget

12. Show MAC address in the Bluetooth / WiFi setting windows (in the title of the window)
13. Optimize the TIME SETTING operation logic
14. Optimize the FFT SPAN (or FFT ZOOM), now it has four items: 100k,50k,25k,12.5k

15. Optimize the "Flat-Menu" operation logic, Press "MFK" to select the current item to the fast-access tag and return to the main window
example 1: In "RADIO SETTING1" page, "TX POWER" is selected, press "MFK" then "TX POWER" is added to the fast-access tag
example 2: In "DISPLAY SETTINGS" page, "FFT SPAM" is selected, press "MFK" then "FFT SPAM" is added to the fast-access tag
*Note: "selected" means the item get the focus

16. Optimize AGC algorithm
16.1 AGC time constant is more accurate
16.2 Background noise is much lower without antenna plugged in (except FM mode)

Tips & Note:
#### Most of the CI-V instructions compatible with ICOM-705
#### Ham Radio Deluxe may not recognize the bluetooth virtual serial port
#### Serial port remap (could be critial when working with the bluetooth virtual serial port):
Why remap:
FLRIG/WSJTDX/JTDX may fail to connect to the bluetooth virtual serial port (due to the mechanism of rfcomm itself

App: V1.1.5 Apr 10 2022,13:12:01
1. Fix bug: the last character in the string of "AGC mode" is half cut off in MEMO mode
2. Fix bug: CW decoder not working
3. Fix bug: incorrect UTC offset/Time zone
4. Change the range of built-in/handheld speaker's MIC gain:
Old version: range 0~36, default 10; actual gain 0~+18dB, step 0.5dB
This version: range 0~50, default 20; actual gain -10~+15dB, step 0.5dB

Base: V1.1.5 Apr 9 2022,17:14:40
1. Fix bug: battery can't be fully charged
2. Fix bug: won't charge at power off state (occasionally)
3. Fix bug: have to switch band or press PTT once at the first time of power up, or there's no output RF power
4. Fix the problem that the built-in/handheld speaker's MIC gain is too high
5. Fixed the problem that the gain adjustment of the built-in/handheld speaker is not obvious

App: V1.1.4 Feb 16 2022,17:15:50
1. Add FFT peak hold switch, GEN > DISPLAY SETTING > FFT PK HOLD
2. Fix bug "Gate Way" can't save in "WLAN" setting page
3. Change rx volume from 0-50 to 0-55(5dB more than prev version)
4. Change CW decoder's threshold to a higher level(better robustness but needs higher SNR)
5. Calibrate the RX S-Meter giving more accuracy
6. Add ALC level indicator(at the top-right of the bandscope area, below the tx power strings)
7. Optimize the Fw flashing logic(base board will boot-up itself after flashed the Fw)

Base: V1.1.4 Feb 15 2022,13:19:59
1. Fix bug built-in MIC feedback to speaker sometimes
2. Fix bug base board some times not booting at power on
3. Optimize ALC algorithm
4. Optimize SWR algorithm, less jumping around
5. Optimize switching power synchronization algorithm, less birdies

☆ ALC tricks
a) ALC level equ to 0: over driving, decrease input signal level
b) ALC level equ to 100: under driving, increase input signal level
c) When doing Digi,the audio baseband signals are almost constant amplitude,
adjust the soundcard volume to make ALC level between 20-80 to get good linearity

App: Version V1.1.3 Jan 15 2022,14:48:38
1. Correct the problem of wrong frequency division of 6m (original division: 50.1M~54.0M, modified to: 50.0M~54.0M)
2. The conditions of low-battery shutdown are modified to: battery <10% and voltage lower than 7.3V to prevent low-battery shutdown by mistake when the fuel gauge is not calibrated.

Base: Version number V1.1.3 Jan 25 2022,14:21:03
1. Fix the problem that the RTS signal of the CI-V/CAT port could not control the CW transmission

☆ The CAT/CI-V port can be viewed in the device manager, generally called USB-Enhanced-SERIAL-B CH342 (COMx)
Where COMx is the port number, x is a number, such as: COM3
If you find that you can't connect it, you can try to connect via the corresponding port number of USB-Enhanced-SERIAL-A CH342.

☆ How to use N1MM Logger+ to send CW:
Config->Configure Ports, Mode Control, Winkey, etc...
The first page in the pop-up menu [Hardware]
Port drop-down box to select COMx
Radio drop-down box to select IC-7000
Digi remove the tick
CW/Other checkmark
Click Details/Set, and set in turn:
DTR(pin 4)=Always off,RTS(pin 7)=CW
The rest are all defaults, click OK

APP : V1.1.2 Jan 17 2022,16:31:45
BASE : V1.1.2 Jan 17 2022,15:44:18

1. In-machine coulometer is enabled to manage battery cell. After the upgrade, the battery capacity, rather than battery voltage, measured by the coulometer is taken as management data. Precautions are as follows:
1.1) After upgrading firmware, please fully charge and discharge the battery for successive 4 times, after which the measurement of the coulometer will be accurate.
After just upgrading the firmware, the error of electric quantity displayed is large before the 4 charges and discharges as mentioned above, so it can be ignored. The charging process shall be kept continuous until the charging instruction indicates it has been completed, which is conducive to the accurate measurement of the capacity by the coulometer.
1.2) The status of the upgraded charging indicator light is as follows:
Flashing: charging
Normally on: charging completed
Off: once the charging option is disabled in the menu, the indicator light will not be off.
1.3) When the electric quantity is below 10% after the upgrade, the battery icon is displayed in red with an empty interior, and the device will automatically shut down.
1.4) Battery voltage is no longer taken as the basis of low power.
2. Parameter adjustment in GEN menu is changed to non-circulating, which can be switch by rotating the large knob to left or right.

8. The problem that label of axis X scanned by SWR does not upgrade is fixed.
9. The bandwidth of first group of filter of SSB is widened to 50-2950Hz(2.9k).
10. The problem of save failure after adjusting the filter is fixed.
11. Indicator string under AGC mode is simplified to AGC-A,AGC-F,AGC-S,AGC--.

13. LSB-DIG and USB-DIG strings are simplified to L-DIG and U-DIG.
14. Hand microphone button function is enabled.
14.1) SPCH/LOCK: short press=lock/unlock larger impeller; long press=none
14.2) TUNER/CALL: short press=switch on/disconnect automatic antenna tuner; long press=enable automatic antenna tuner
14.3) XFC: short press=switch VFO A/B; long press=copy VFO from foreground to background
14.4) V/M: short press=switch VFO/MEMO mode; long press=none

14.8) UP: frequency+stepping position under VFO mode; next channel under channel mode
14.9) DOWN: frequency-stepping position under VFO mode; last channel under channel mode
14.10) F1/F2: allow setting custom functions in RADIO SETTING2

    Hi Mauricio, please just load the latest one.

  • Mauricio

    I have a firmware version Base V1.1.1 and would like to update it. For this, I must install each previous firmware version, or can I directly load the latest one and it already contains all the previous improvements?

  • Randy Gudeahn

    For some reason, when I select USB DIGI, it will not stay in that mode.

  • Steve M7CYW

    Okay… after noticing a comment about a previous firmware upgrade, I plugged power in… this time the upgrade worked correctly.

  • marco

    I cross checked this. 1.1.2 jan 17 breaks tx via usb under windows. Downgrade to 1.1.2 dec 30fixes it.
