Hi Bob,
The new frequency coverage is still part of the 160-meter band. If you need
quick access to the 600-meter range (~475 kHz), you can use any of several
different ways to get to it:
- the four per-band "quick memories" on 160 m
- the 100 general-purpose memories
- direct frequency entry
- a programmable function switch
As an example of the latter, you could create a K3 command macro using K3
Utility, such as:
FA00000475000;MD3;PA0;
This sets VFO A to 475 kHz, CW mode, with the preamp off. Of course you would
also want to bring the signal in through RX ANT IN or XVTR IN, so the high-pass
filter in the T/R switch is bypassed. Using XVTR IN requires setting
CONFIG:KXV3 to TEST. We may provide a simpler way to do this in the future.
