Re: LO off QRG

Igor,

There is much that goes on in the firmware that makes it hard to predict how the hardware will work.  But the behavior you see is normal.  Setting the REF frequency accurately will either solve your problem or tell you there is a problem with the oscillator or the control voltage from the CPU.

Your unit's hex value for REF of 9B is higher than typical in the four radios I have recorded the values for ((typically 55-76), but accurate measurement is the only way to set the frequency so that the IF stages work corrrectly.
