Thank you, your information helped a lot.
Now to the issue...
It turns out that people who play only using the keyboard (hardcore, right?) do not need to wait for RAZBAM to "fix" this, as there is a way around the whole cycle radar switch problem, and it goes like this:
1. Go to the "Disk_X:\Folder_X\DCS World\Mods\aircraft\F-15E\Input\F-15E\keyboard" folder.
2. Locate and open the "default.lua" with an text editor.
3. Find the "Sensors Panel" section.
4. Replace these lines:
{down = snsrctrl_commands.rdr_kb, cockpit_device_id = devices.AN_APG70, value_down = -0.33, name = _('AN/APG-70 Radar: EMERG/ON/STBY/OFF'), category = {_('Left Console'), _('Sensors Panel')}},
{down = snsrctrl_commands.rdr_kb, cockpit_device_id = devices.AN_APG70, value_down = 0.33, name = _('AN/APG-70 Radar: OFF/STBY/ON/EMERG'), category = {_('Left Console'), _('Sensors Panel')}},
With these lines:
{down = snsrctrl_commands.rdr_power_sw, cockpit_device_id = devices.AN_APG70, value_down = 0.99, name = _('AN/APG-70 Radar: EMERG'), category = {_('Left Console'), _('Sensors Panel')}},
{down = snsrctrl_commands.rdr_kb, cockpit_device_id = devices.AN_APG70, value_down = -0.33, name = _('AN/APG-70 Radar: EMERG/ON/STBY/OFF'), category = {_('Left Console'), _('Sensors Panel')}},
{down = snsrctrl_commands.rdr_power_sw, cockpit_device_id = devices.AN_APG70, value_down = 0.0, name = _('AN/APG-70 Radar: OFF'), category = {_('Left Console'), _('Sensors Panel')}},
{down = snsrctrl_commands.rdr_kb, cockpit_device_id = devices.AN_APG70, value_down = 0.33, name = _('AN/APG-70 Radar: OFF/STBY/ON/EMERG'), category = {_('Left Console'), _('Sensors Panel')}},
{down = snsrctrl_commands.rdr_power_sw, cockpit_device_id = devices.AN_APG70, value_down = 0.66, name = _('AN/APG-70 Radar: ON'), category = {_('Left Console'), _('Sensors Panel')}},
{down = snsrctrl_commands.rdr_power_sw, cockpit_device_id = devices.AN_APG70, value_down = 0.33, name = _('AN/APG-70 Radar: STBY'), category = {_('Left Console'), _('Sensors Panel')}},
5. Do some formatting to align the lines so that columns are even (use TAB key) (optional). Save the file and close it.
6. Launch the DCS World and go to OPTIONS -> CONTROLS -> F-15E.
7. Bind the "AN/APG-70 Radar: ON" and the "AN/APG-70 Radar: STBY" actions to your liking.
