Active Memory Recall
As long as the <RCL> button is illuminated, you can actively scroll through
frequency memories without having to recall each one. To turn active scroll
off, tap <RCL> again.
Quick Memories
Quick memories are typically used to store per-mode starting points on each
band. For example, on 20 meters you might store 14.040 CW in M1, 14.074
DATA in M2, 14.085 FSK in M3, and 14.250 USB in M4. This is an alternative
to using band-stacking registers.
To store a quick memory:
• Tap [STORE].
• Tap [M1]-[M4]. This will also dismiss the frequency memory window.
To recall a quick memory:
• Tap [RCL].
• Tap [M1]-[M4]. This will also dismiss the frequency memory window.
USING SPLIT
Normally, VFO A is used for both receive and transmit. In SPLIT mode, the K4
transmits on VFO B.
SPLIT is useful if you're working a DX pileup using VFO A to listen to the DX
station, with VFO B as your calling frequency, and have the sub receiver
turned off. (The alternative is to turn the sub receiver ON, listen to the DX
station on VFO B/sub, and use VFO A/main as your transmit frequency. This is
generally more effective, since you can hear both frequencies at the same
time.)
