NVIS equipment
#6
Hi NR, hows the back?

NVIS for the unknowing is "ham speak" for Near Vertical Incidence Skywave or low frequency transmitters working from 1.8mhz to 10mhz with vertical or inverted v aerials.

Sort of CB sets working at low frequencies. (CB sets work at 27 Mhz)
Typical modes include morse code and SSB.

You'll need a ham foundation licence to work this and then you are limited to 10 watts.

Problems include:-
Aerials are BIG typically in an inverted v 35' long.
Aerials usually need to be tuned in using an aerial tuning unit.
Both ends need to be working NVIS to achieve reliable communications.
You'll need a ham licence.
and of course if you're working morse, you'll have to learn morse!!!!!!!!!!!







Morse is fun.
It's not quite just learning the code though it's also about the timing i.e.

1. A dot is worth 1 unit (you decide how long that is).
2. A dash is equal to 3 dots
3. The space between parts of the same letter is equal to 1 dot
4. The space between two letters is equal to 3 dots
5. The space between two words is equal to seven dots.

Shall I go on? (Y) -.-- or -. (N)

Would you like the morse code now ? (Y) -.-- or -. (N)
