Have you taken the steps needed to allow ANYONE in your group to communicate with you?  Something that is often overlooked is that while WE may know what is needed, the person on the other end may very well not.

A simple How To printed out and left by the radio can mean the difference between comms or no comms.

Below is the one I printed out for my wife to get our base unit up on the “Prepper’s 80M” channel that I plan to call here with in the event I’m stranded at work 50 miles away.

I suggest doing the same for your setups.  Not just comms, but anything around the house that might need done while you are gone if SHTF like changing the house over to rain water, switching to solar only, etc.

Steps to Setting up Radio for 80M Comms:

    1. Turn #4 Clockwise to turn on radio
    2. Check that #5 is centered straight up
    3. Usually the Band B “bottom” is pre-configured for Emergency Comms.
      1. If you see (Feq 3.818.000) on the bottom, use the #28 [A/B] button in the upper right to switch the bottom band to Band A “top”.  CONFIRM all is set according to steps #6 – #8 otherwise go to step #4 below.
    4. Change Band A “top” to 80M (Feq 3.818.000) by pushing #21 [BAN] until the you see 3.xxx.xxx in the display .
    5. Use #13 to dial in the exact 3.818.000 freq then hit #15 [LOCK]
    6. Make sure that the number next to BW on the screen is set at 2400 by turning the #31 dial completely clockwise
    7. Toggle #23 [MOD] until you see “LSB”
    8. Check that PWR is at 100 watts.
      1. If it is not, hit #12 [FNC] then turn #26 [MULTI] clockwise.
      2. Hit #12 [FNC] again and “FUNC” should stop flashing.
    9. If the AT-100ProII Autotuner is attached to the radio (should be by default) then you are ready to transmit.20180914_163716
  1. If the MFJ Manual tuner shown below is attached, then see TUNING THE RADIO on next page…

Tuning the Radio:

  1. Make sure the ANTENNA SELECTOR is on TUNED COAX 2
  2. With the volume up on the Radio so you can hear the static noise, switch the INDUCTOR SELECTOR slowing between settings A-L listening for the loudest static noise. When you hear one that sounds the loudest, switch the dial forward and backwards to confirm it is the loudest setting.
  3. Swing the ANTENNA MATCHING dial slowly back and forth throughout the entire span and listen for the noise to increase even more. Stop on the loudest setting. Helps to close your eyes.
  4. Now swing the TRANSMITTER MATCHING dial the same way and leave it on the loudest setting.
  5. Once you have the loudest static setting, you should be close to being tuned and fine-tuning can start.
  6. To fine-tune, you will need to transmit on the radio using the #25 TUNE button. This button will output a tone after you press it and will continue to do so until you toggle it off by pressing again.
  7. Press the #25 TUNE button and watch the needles on the MFJ-941E tuner.
  8. The left FORWARD needle should go to about 20W and the right REFLECTED needle should be on ZERO or at least under 2:1
  9. IF THE LEFT NEEDLE RISES ABOVE ½ WAY TO THE CENTER OF THE ARC, STOP TRANSMITTING!
  10. Perform steps 1-4 again making sure the noise levels are always the highest before continuing on.
  11. Once the level is below 2:1, you may speak into the mic without worry of hurting the equipment.
  12. You only have to tune the radio once unless you change the frequency.

One thought on “Emergency Comms: “How Tos” for those that don’t know “How To!”

  1. sweet idea and well done for someone who may not know how to operate your radio. Will be doing this for mine as well for family members in case I’m away from home.
