Does your Emcomm (Emergency Communications) Plan Include NVIS?

I'm not an expert with HF. But what I know is that NVIS, or Near Vertical Incidence Skywave, propagation is probably my favorite communication and deployment technique because I can use HF radio to communicate within a region with my people. Note: 2 stations ran 5 Watts and one station used 10 Watts. This was all low power on battery power.
Does NVIS work during the day?
Huge Thank You to ‪@hamradiowithkevin‬ for putting this comms test together.

antenna height is everything. You will need to experiment with yours to get what you want out of it.

Don't forget about the 60 meter band. When skip is too long on 40 meters and D-layer absorption is high on 75/80 meters, 60 meters can be an excellent option.

@backcountryamateurradio Год назад

Looks like I need to get to work on a 60m antenna! Thank you for the advice.

@hamradiowithkevin Год назад

Really nice seeing how your setup was at the park Eric. What a great demonstration. It is so fun to work you with so many different setups this last season. Thank you for all that you do.

@backcountryamateurradio Год назад

Really, the thanks goes to you, Kevin. You made all this happen. These videos are nice to have because I can literally look back on it and see how much fun we had. Thanks for providing so much footage and for setting this NVIS test up. I hope we can do a lot more next year. Thank you Kevin, have a nice weekend! 73

@AnthonyCharles-ho7ch Год назад

exactly what we needed to know. NVIS sounds good on 75m and 40m when we are awake. tu de K5TZ

@backcountryamateurradio Год назад

To be fair, I don't know if I've NVIS sound this good at night! Thank you for watching, 73 - Eric, KI7WJP

@robertbird7297 Год назад

I agree that it is important to practice your setups…..practice makes perfect. Thanks Eric!

@backcountryamateurradio Год назад

Absolutely! I took out all the footage of me getting there, realizing I'd forgotten some critical hardware... then going back to the shack, and returning, just time time to catch the other guys. I was a bit out of practice myself. Thank you Robert.

Great video and great audio coming through for you guys! 73!

@backcountryamateurradio Год назад

Thank you! it was amazing how well we were all coming through. I'll tell you though, capturing all that audio got a little tricky. But pulling that experiment off was a stellar show of how useful radio can be out there. Have a great weekend - 73

@davidnelson6889 Год назад

Awesome video Eric. Thanks for sharing.

@backcountryamateurradio Год назад

Thank you and thanks for checking it out David. It was a lot of fun and I hope to do more of it. I'm still impressed by how clear our transmissions were. One may have thought we were using VHF.

Thanks for doing this. I have a fishing backpack set up with my 817 batteries tuner and wire antenna for NVIS but was not sure how well it would work QRP. I can also tie into my car 100W if needed. Maybe I will give the QRP a shot next field day. My coworker ran NVIS while deployed in Afghanistan. They ran 5W secure comms. In cases where it was a hot situation he said they would put the antenna only a couple ft off the ground.

Thanks for this comment! I hope you've had some great experiences with NVIS. It's a great technique. In fact, it is a borrowed technique from military operators. Interesting to hear about it in use in the field. Hopefully you've come across the Tech Prepper's channel where he does a whole lot of comm testing with NVIS. 73

@chrisdonner2910 Год назад

Another great video, thanks for sharing! Learning a lot

@backcountryamateurradio Год назад

Thank you, Chris! I’m grateful you’ve found this stuff useful. NVIS is a ton of fun and a practical way to bypass the use of repeaters.

@neubert500 Год назад

Excellent video! Thanks for sharing your results. 73

@backcountryamateurradio Год назад

Happy to share! I'm still just learning all this stuff myself and I hope it helps someone along the way. I know I learned a few things! haha! Thank you, 73 - Eric

@jstrunck Год назад

Yessir…, nvis comms are paramount at my QTH. 73 sir

@backcountryamateurradio Год назад

Makes sense to me. I wish we could have an 80m NVIS antenna here at my shack. 73 - Eric

@jstrunck Год назад

NVIS antenna here is Chameleon Emcomm II at 12 feet up. In between the Hustler 6btv vertical and the Emcomm II, there are not too many places I cannot establish a comms path with.

@backcountryamateurradio Год назад

@@jstrunck that sounds like a lot of fun!

@KI4ASK Год назад

Great stuff Eric

@backcountryamateurradio Год назад

Thanks Joe! I think it was an exchange I had with you that prompted me to get my 80m antenna built. So, thank you again!

@KI4ASK Год назад

@@backcountryamateurradio We do a lot of NVIS here in Georgia. Great stuff.

@VE7QH Год назад

fantastic video, really gives me some ideas that I would like to try out with my station as well. I would like to see this tested with the Chameleon MPAS in the vertical config since they claim it to be an NVIS antenna

@backcountryamateurradio Год назад

I have heard of verticals being used for NVIS. I have no experience with them. I hope you can get out there and put those ideas into play. It's a ton of fun. Thank you for watching! 73

@Flatus4La Год назад

Eric ... you were transmitting at 2.5 watts ("L" symbol/power meter with 3 bars is 2.5 watts ... lack of any symbol means full 5 watts) so test is more impressive than you think! The 817 manual is confusing.

@backcountryamateurradio Год назад

Well, Thank you! I guess if there's a good prank for my radio to play on me, that's it!

Spanish Fork to Heber? that ain't ground wave. I recall a few mountains in the way. Something about a Timp. Dropped my antenna to 1-8 feet and still hitting most of the continent on 40/80
