>>283839I forgot to mention, the meter needs to be on "IC".
For final tuning, switch the meter to PO (Power Output, basically, wattage).
Set CARRIER to 2.
Key up (MAX 10 SECONDS), and while holding the key, tweak PRESELECT for maximum meter reading. You will see a dip if you're too high or too low. Release key, wait 10-15 seconds for the amp to cool.
Key up, tweak LOADING for maximum meter reading. Wait to cool.
Key up, tweak PLATE for maximum meter reading. Wait to cool.
Go back to the CARRIER, increase to 4, repeat all processes again.
>repeat until CARRIER is at 10.As you learn the radio, you will get fast at doing this. You DO NOT want to key up for a long period of time. Work quickly...when the carrier is at 10, you are transmitting at 100% duty cycle... I popped a tube on my DX40 after leaving it keyed up for about 40-50 seconds while I was trying to figure it out. Go slow, give it time to cool.
Once you're done, congrats, you're ready to transmit.
I also forgot to mention, the MODE knob needs to be on TUNE.
After final tuning, you can run SSB, AM, or CW. AM or CW require some additional tuning for the CARRIER. SSB (LSB or USB) requires no additional tuning.
