Hi all,
We've been testing an experimental (field-test) KX3 firmware release that has the following features:
- Both PSK31 and PSK63 modes
- Up to 15 W power output (all modes) on 80-20 meters
- Increased power output on 4 meters (with KX3-4M module; some units were not making target of 2.5-3.0 W)
If you'd like to try this release, please email me directly. I'll take the first 15 or so. If I don't send you the new firmware today, hang in there -- it should be beta in a week or two.
Note on 15 W output level: This requires a power supply voltage of 12.8 V or higher on key-down as indicated by the KX3 itself (on the VFO B display). All of the usual firmware protections apply, i.e. the KX3 will roll power back to a lower level if necessary to keep current drain and temperature within a safe range, or if supply voltage is too low. 12 W max is the generally recommended level, so 15 W should be used only when really needed. And again, this is experimental.
73,
