MFJ-9420 With digital dial

It is in the 14.000Mhz or 20m band. The way the dial reads is 4.161.8 Mhz, but one would actually read it as 14.161.8Mhz. I use this digital dial on my MFJ antenna HF antenna analyzer as well.
Digital frequency readout option. I installed a BNC jack and proper sip socket connection to #46 resistor vs the U7 pin 6 on the same trace towards transistor. I was careful to tac solder one end on board. I have seen this on Youtube and decided to tackle it. Just ordered it on Sunday and it arrived today on Wed. which was super quick shipping. Back in 2009 I had the older versions of these radios for 20 and 40m and made some good contacts with them. Now I want them for field use at picnic tables. The meter is not really accurate as it is off by 4Khz so it should be 14.157.8 instead of 14.161.8 as I compared it to my Icom 718 signal. I can always subtract 4khz or get a different frequency counter.
