Sub Rx freeze

George Thornton
This might be something obvious I am overlooking.

 

I have experienced a few instances of the sub RX tuning knob freezing.
I spin the knob but the frequency does not change.

 

Sometimes turning the unit off and then back on gets things moving
again.

 

I have tried linking and unlinking the sub Rx.  No change.

 

I suspect I have done something with a menu or control setting but I
don't know what I could have done.

 

The radio is equipped as follows:

 

K3/100

KAT3

KRX3

KXV3A

KDVR3

KBPF3 (in main Rx)

 

 

Main has 13, 6, 2.8, 1.7 and 250 filters

Sub has 6 and 2.8.

 

I am powering off of an Astron RS-35M with a battery backup monitored by
a West Mountain Powergate PG40s.  

Because I am using AGM backup batteries, per instructions the voltage
setting of the RS-35m was increased to 14.5 volts.

 

The radio had a full factory workover in June and should be in good
operating order.

 

I am using the latest beta firmware.

 

I DO NOT have the P3.

 

I am wondering if it is the firmware, I don't recall this happening
before.
