already reported Radio Presets accept invalid values

[FalcoGer]

According to the DCS Documentation:

• Max freq for UHF radio in preset is 399.975 MHz, but AH64 allows entry up to 399.980 MHz
• Min step size for UHF radio preset is 0.025 MHz, but AH64 allows entries to a resolution of 0.005 MHz (for example 380.995, whereas it should be 381.0 or 380.975)
• FM radio max frequency is 87.975, but AH64 allows entries up to 87.990
• FM radio frequency step size is 0.025, but it is actually 0.005, allowing entries like 77.995. Also the default preset that is tuned from mission start for an AH64 for FM1 is 30.015 (Preset 3) and for FM2 it is 30.020 (Preset 4), both of which are invalid, or the documentation is wrong.
• VHF min frequency is 116, but AH64 allows entries down to 108
• VHF max frequency is 151.975, but AH64 allows entries up to 155.995
• VHF frequency step size is 0.025, but AH64 allows resolution of 0.005, allows invalid values such as 116.995

Other things that are wrong but not in the DCS documentation:

• CNV for HF radio starts at 0, but valid options are only 1 through 6, when tuning an HF radio with crypto enabled and C0, this is not displayed. Only C1-C6 are displayed when a valid value is entered for CNV.
• Preset channel for HF starts at 0, but AH64 rejects anything that isn't 1 through 20. 0 can not be set once it has been set to something that is not 0.
• ALE Net starts at 0, but 0 can not be re-entered once it has been set to something other than 0.
• ECCM net starts at 0, but 0 can not be re-entered once it has been set to something other than 0
• Tuning an HF preset any frequency results in a wrong frequency being tuned on the EUFD (5.0500A)
• Tuning that same preset again will push the correct frequency into the standby frequency, but SWAP doesn't do anything. It might just be a display error
• Some Presets start with HF being 0.0000 for XMIT and RECV. Tuning them results in 15.0000A being displayed in the EUFD.

The frequency tuning ranges and intervals are already reported for the VHF, UHF, and FM radios.

The VHF radio can be tuned down to 108 for receive only of navaid information.

The HF radio is not implemented aside from its manual frequency tuning capability.

I checked again. The documentation provided by ED is wrong.

• The VHF radio can be tuned 108.000 through 155.995, the VHF radio accepts the correct frequencies. The documentation about the step size is wrong.
• The UHF radio can be tuned 225.000 through 399.985 MHz in increments of 5 KHz. The DCS apache can only go up to 399.980. Again, documentation about step size is wrong.
• FM1/2 range is 30.000 through 87.995, in increments of 5 KHz. The DCS apache can only go up to 87.990. Documentation wrong about step size.

The DCS AH-64D Early Access Guide is accurate. The tuning ranges and intervals for the four primary radios are listed below:

VHF radio: 108.000 - 151.975 MHz, in 0.025 increments
UHF radio: 225.000 - 399.975 MHz, in 0.025 increments
FM1/FM2 radios: 30.000 - 87.975 MHz, in 0.025 increments

As stated, there is already a report submitted to rectify the radio tuning capabilities in the AH-64D cockpit, and in the Mission Editor; although in the case of the Mission Editor the tuning interval is the only issue whereas the tuning ranges are accurate.

However, after reviewing the DCS EA Guide, there is one location on page 267 that fails to mention the possibility of tuning 108.000-115.975 for receive only operations. Although the VHF receive-only frequency range below 116.000 is mentioned in other locations in the EA Guide, this particular location needs to have it added.
