1. Remove the duct tape from the back, it should have caught some shavings


2. And remove the duct tape from the front


3. Now wire the switch. The labels really help.


4. DOUBLE AND TRIPLE CHECK THE WIRING! Get this wrong and you WILL short the different RF and IF amplifier supply voltages together and MESS UP YOUR VA62! Don't blame me, I warned you. Now install the switch into the front panel


5. Apply a water transfer decal to label the switch and give it a try. You did wire the switch right? RIGHT? What could go wrong?
Hopefully it did not blow up. Set the RF-IF SIGNAL switch to 35-50 MHz PROG and enter 1500 to output a 15.00 MHz signal. Set the VIDEO PATTERN to External Modulation (with no signal driving that input) and set the AUDIO switch to off. You should get a clean sine wave (as well as the components will allow) out of the RF-IF OUT with its level controlled by the setting of the manual RF-IF DPDT toggle switch you added.


Next we will try to output an early TV low band IF signal.
