Anyone know where the transmit frequency adjustment is on the HS4 boards?

Also, a local friend of mine asked me if there's any way to add the VFO windup to the Retevis HS4, I told him I wasn't sure and would have to look over the schematic first. However, I can't find a scheme for this radio, and the anytime 5555 shows np transmit frequency adjustment.
 

Search for AT-5555 frequency adjustment - it is the same procedure as the newest versions will apply to the HS4. It is menu driven. Here:



HOWEVER - the chances of a new HS4 being off-frequency are extremely low. This almost never happens. These radio are rock solid stable. What issue are you having?

The HS-4 has no VFO support, the firmware doesn't allow for it unfortunately. It is stuck in CH mode with some ability to move +/- with the clarifier control, in a VFO-ish way.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
