[Elecraft] K3 Firmware bug w/K144XV

K3 s/n running v4.03 f/w
KRX3 installed
K144XV installed

Have entered a local repeater freq/offset/pl tone into VFO A
Output/K3 RX: 147.285, positive offset (147.885 Tx) pl 103.5

Have another local repeater output freq on VFO B: 146.760

Can hear both repeaters fine.

Once I TX on VFO to use the first repeater (Txing on 147.885), the Sub RX
readout changes to 147.760. (The MHz digits go to the same as VFO A.)
However, if I use an HT to open the second repeater (146.760 output), The K3
can still hear it, even though the display says 1 MHz higher. So, it looks
like a display shift, rather than actual operating frequency. This behavior
is the same whether VFO IND is Yes or No.

I understand that the K144XV uses different LO crystals for 144-146 vs.
146-148, and simultaneous monitoring of 2 freqs in separate segments would
not be allowed. However, these two repeaters are both in the upper segment,
and the firmware should allow this.

Can anyone else replicate this behavior?
