You can enable RX and adjust VOLUME and SQUELCH into your liking.
Sadly enough, you will NOT be able to use VOICE ACTIVATION when RX is enabled (to ensure there will be NO audio feedback defeating the VA sensing)
A "bug" that won over me, but perhaps and hopefully other coder can easily fix: The Vumeter will momentarily "dissappear" when enabling RX. But it will reappear as soon as you start TX. Or when you turn off RX.
I enabled the PEAK LEVEL MARK on the Vumeter, so you can easily see in which level your input voice / signal is peaking and regulate the MIC gain accordingly in an easier / more robust way.
Side enhancement: Took off the dark green, yellow and red coloring from the vumeter when no signal is present, and replaced it with dark_grey. I know that some coloring is "eye-candy" but the vu-meter is more readable with this new contrast.
It reads the antennas definition from a txt file:
WHIPCALC/ANTENNAS.TXT
Inside the textfile you place each antenna you own with the following sintaxis:
<antenna label> <elements length in mm, separated by a space>
For example:
ANT500 185 315 450 586 724 862
Input the required frequency, adjust the wave type (full / half / quarter, etc.) and the calculator will return the antenna length (metric and imperial) while also calculating how much you need to expand the fitting antennas you got defined on the txt.
It may return up to 8 matching antennas, which is more than enough (normally you will have 2, perhaps 3 telescopic antennas around for your portapack)
If by any chance your antennas txt got more than 8 antennas, and more than 8 matches the length of the freq / wave you want, it will only show the first 8 matching antennas and will warn you at the bottom that there are even more results (hidden).
All calculations now are rounded into the best integer, considering first decimal, so precision is double than the original antenna calculator app.

* MAX V CPLD: Reverse verify data checking logic to make it a little faster.
* CPLD: After reprogramming flash, immediately clamp I/O signals, load to SRAM, and "execute" the new bitstream.
* Si5351: Refactor code, make one of the registers more type-safe.
Clock Manager: Track selected reference clock source for later use in user interface.
* Clock Manager: Add note about PPM only affecting Si5351C PLLA, which always runs from the HackRF 25MHz crystal.
It is assumed an external clock does not need adjustment, though I am open to being convinced otherwise...

* Bootstrap: Explicitly configure IDIVB for SPIFI, despite LPC43xx bootloader setting it.
* Clock Manager: Init peripherals before CPLD reconfig. Do the clock generator setup after, so we can check presence of PortaPack reference clock with the help of the latest CPLD bitstream.

* Bootstrap: Consolidate clock configuration, update SPIFI rate comment.
* Clock Manager: Use IDIVA for clock source for all peripherals, instead of PLL1. Should make switching easier going forward.
Don't use IRC as clock during initial clock manager configuration. Until we switch to GP_CLKIN, we should go flat out...

* PCB: Revise U1 pad shape, mask, paste, thermal drills.
Clearance is improved at corner pads.
* PCB: Tweak U3 for better thermal pad/drill/mask/paste design.
* PCB: Change solder mask color to blue.
* Schematic, PCB: Update revision to 20181029.
* PCB: Bump minimum mask web down a tiny bit because KiCad is having trouble with math.
* Update schematic
* Remove unused board files.
* Add LPC43xx functions.
* chibios: Replace code with per-peripheral structs defining clocks, interrupts, and reset bits.
* LPC43xx: Add MCPWM peripheral struct.
* clock generator: Use recommended PLL reset register value.
Datasheet recommends a value. AN619 is quiet on the topic, claims the low nibble is default 0b0000.
* GPIO: Tweak masking of SCU function.
I don't remember why I thought this was necessary...
* HAL: Explicitly turn on timer peripheral clocks used as systicks, during init.
* SCU: Add struct to hold pin configuration.
* PAL: Add functions to address The Glitch.
https://greatscottgadgets.com/2018/02-28-we-fixed-the-glitch/
* PAL/board: New IO initialization code
Declare initial state for SCU pin config, GPIOs. Apply initial state during PAL init. Perform VAA slow turn-on to address The Glitch.
* Merge M0 and M4 to eliminate need for bootstrap firmware
During _early_init, detect if we're running on the M4 or M0.
If M4: do M4-specific core initialization, reset peripherals, speed up SPIFI clock, start M0, go to sleep.
If M0: do all the other things.
* Pins: Miscellaneous SCU configuration tweaks.
* Little code clarity improvement.
* bootstrap: Remove, not necessary.
* Clock Manager: Large re-working to support external references.
* Clock Manager: Actually store chosen clock reference
Similarly-named local was covering a member and discarding the value.
* Clock Manager: Reference type which contains source, frequency.
* Setup: Display reference source, frequency in frequency correction screen.
* LPC43xx API: Add extern "C" for use from C++.
* Use LPC43xx API for SGPIO, GPDMA, I2S initialization.
* I2S: Add BASE_AUDIO_CLK management.
* Add MOTOCON_PWM clock/reset structure.
* Serial: Fix dumb typos.
* Serial: Remove extra reference operator.
* Serial: Cut-and-paste error in structure type name.
* Move SCU structure from PAL to LPC43xx API.
It'd be nice if I gave some thought to where code should live before I commit it.
* VAA power: Move code to HackRF board file
It doesn't belong in PAL.
* MAX5 CPLD: Add SAMPLE and EXTEST methods.
* Flash image: Change packing scheme to use flash more efficiently.
Application is now a single image for both M4 bootstrap and M0.
Baseband images come immediately after application binary. No need to align to large blocks (and waste lots of flash).
* Clock Manager: Remove PLL1 power down function.
* Move and rename peripherals reset function to board module.
* Remove unused peripheral/clock management.
* Clock Manager: Extract switch to IRC into separate function.
* Clock Manager: More explicit shutdown of clocks, clock generator.
* Move initialization to board module.
* ChibiOS: Rename "application" board, add "baseband" board.
There are now two ChibiOS "boards", one which runs the application and does the hardware setup. The other board, "baseband", does very little setup.
* Clock Manager: Remove unused crystal enable/disable code.
* Clock Manager: Restore clock configuration to SPIFI bootloader state before app shutdown.
* Reset peripherals on app shutdown.
Be careful not to reset M0APP (the core we're running on) or GPIO (which is holding the hardware in a stable state).
* M4/baseband hal_lld_init: use IDIVA, which is configured earlier by M0.
This was causing problems during restart into HackRF mode. Baseband hal_lld_init changed M4 clock from IDIVA (set by M0) to PLL1, which was unceremoniously turned off during shutdown.
* Audio app: Stop audio PLL on shutdown.
* M4 HAL: Make LPC43XX_M4_CLK_SRC optional.
This was changing the BASE_M4_CLK when a baseband was run.
* LPC43xx C++ layer: Fix IDIVx constructor IDIV narrow field width.
* Application board: hide the peripherals_reset function, as it isn't useful except during hardware init.
* Consolidate hardware init code to some degree.
ClockManager is super-overloaded and murky in its purpose.
Migrate audio from IDIVC to IDIVD, to more closely resemble initial clock scheme, so it's simpler to get back to it during shutdown.
* Migrate some startup code to application board.
* Si5351: Use correct methods for reset().
update_output_enable_control() doesn't reset the enabled outputs to the reset state, unless the object is freshly initialized, which it isn't when performing firmware shutdown.
For similar reasons, use set_clock_control() instead of setting internal state and then using the update function.
* GPIO: Set SPIFI CS pin to match input buffer state coming out of bootloader.
* Change application board.c to .cpp, with required dependent changes
* Board: Clean up SCU configuration code/data.
* I2S: Add shutdown code and use it.
* LPC43xx: Consolidate a bunch of structures that had been scattered all over.
...because I'm an undisciplined coder.
* I2S: Fix ordering of branch and base clock disable.
Core was hanging, presumably because the register interface on the branch/peripheral was unresponsive after the base clock was disabled.
* Controls: Save and expose raw navigation wheel switch state
I need to do some work on debouncing and ignoring simultaneous key presses.
* Controls: Add debug view for switches state.
* Controls: Ignore all key presses until all keys are released.
This should address some mechanical quirks of the navigation wheel used on the PortaPack.
* Clock Manager: Wait for only the necessary PLL to lock.
Wasn't working on PortaPacks without a built-in clock reference, as that uses the other PLL.
