release v0.22

🗲FLASH WITH A BROWSER🗲

Manual:

Up to date manual available in a Wiki section.

Changes:

• Added bands switching to FM broadcast radio function. in FM radio mode press F + 1 BAND or long press 1 BAND. These bands are available in BK1080, and not defined by me. The main benefit is that you can set the band that is used in your country and auto scan function won't scan outside of it.
• Fixed continuous frequency tuning while using long press UP/DOWN in monitoring mode.
• Some other smaller bug fixes

release v0.21

⭐ Dedicated CHIRP driver available at uvk5-chirp-driver

Manual:

Up to date manual available in a Wiki section.

Changes:

• Frequency range scanning in spectrum.
  • Setup frequency range (manual)
  • Turn on spectrum analyzer
  • NOTE: in range scanning frequency blacklisting is limited to 15 frequencies
• Additional frequency steps: 9kHz, 20kHz, 200kHz
• Optimized fixed backlighting of backlight settings
• Fixed backlight timeout doubled
• Fixed battery indicator always showing 4 bars

release v0.20.1

🗲FLASH WITH A BROWSER🗲

Manual:

Up to date manual available in a Wiki section.

Changes:

• Minor fix with S0, S9 settings in EEPROM. There were instances (#252) where there was some garbage data written in that part of the memory, S0 was read as 1 and it led to S-meter not working properly. This is an attempt to eliminate such problems. If your S-meter works correctly you can skip this update, there is nothing else here.

release v0.20

🗲FLASH WITH A BROWSER🗲

Manual:

Up to date manual available in a Wiki section.

Changes:

• AM-fix improvement, so it doesn't get stuck on strong signals like a plane flying over head
• AM-fix in spectrum analyzer
• Improved AGC settings for AM reception. AGC on AM is used when AM-fix is disabled in the menu, or not included in build options. AGC mode is inferior compared to AM-fix but it still should be usable.
• Frequency rounding to half of a step, this allows to enter frequencies with half channel offsets, e.g. PMR frequencies using 12.5kHz step.
• S-meter S-values user configurable. It can be changed with a CHIRP driver that is being developed (very crude implementation right now).
• FM radio mode indicator that I removed some time ago was brought back
• bug fixes (#167, #166, #170, #179, #197, #206)

release v0.19

Manual:

Up to date manual available in a Wiki section.

Changes:

• Scan frequency range function
  • switch to frequency mode
  • set upper and lower VFO frequencies to scan range boundaries
  • long-press 5 NOAA, ScnRng label should show up
  • start scan with long-press * Scan
  • it will scan between given boundaries
  • long-press 5 NOAA or EXIT, or switch VFOs to exit ScnRng mode
• Adjusted s-meter values according to measurements from #53 (thanks to g4eml)
• Use aviation channels to frequency conversion scheme for 8.33 step frequency rounding (thanks to g4eml)
• FM radio buttons functions changed to be the same as in VFO mode
  • long-press support
  • 2 VFO/MR switches channel/frequency mode
  • long-press * Scan starts auto scan
  • short-press * Scan starts manual scan

Manual:

Up to date manual available in a Wiki section.

Changes:

• Adjusted DTMF tones
• 1750 tone volume increased
• Lowered s-meter values
• Fix monitor mode interrupted by PTT and turned back on with any VFO change
• Long press EXIT turns off monitor mode

release v0.17

Manual:

Up to date manual available in a Wiki section.

Changes:

• Improved DCS/CTCSS scanning in a menu RxDCS and RxCTCS (not well known function, enter the menu and press * SCAN)
• Fixed Apollo Quindar PTT ID option. The microphone was muted when that option was active.
• Fixed mic bar displaying over low battery popup
• Mic bar changed to the same style as s-meter
• Fixed shifted audio frequency for DTMF codes 1, 3, A
• TxEnab hidden menu removed. Added new option in hidden menu F Lock, DISABLE ALL with the same functionality. If you used TxEnab you will have to set up the new option.
• TX on all bands (Wiki)

release v0.16

🗲FLASH WITH A BROWSER🗲

Changes:

• SSB demodulation mode added (menu DEMODU)
• New function for programmable buttons to switch demodulator modes (SWITCH DEMODUL)
• More frequency steps (only available in the radio, not available in CHIRP)
• Use the custom battery percentage calculations for battery icon and low battery beeping
• Modified levels for battery icon (3 below 88%, 2 below 65%, 1 below 41%, 0 below %17, blinking below 5%)
• Low battery popup, stops annoying beeping when confirmed
• Fix s-meter over S9 values calculation
• Spectrum analyzer RSSI trigger limited to screen boundaries

release v0.15

🗲FLASH WITH A BROWSER🗲

Changes:

• Fixed STE not working when TX CTCSS/DCS is off
• Fixed DTMF calling, radio was receiving transmissions without active call
• Second discharge curve for 2200mAh battery percentage calculation. You have to change battery type in the hidden menu BatTyp. 1600mAh has very different curve, this was causing wrong indications when 2200mAh battery was used.

v0.14.1
