3.780 Lock Down Net Mon-Fri Daily

NOTE: Using my OWN call as a test since there should be no QSL requests..

I am inviting folks who are a little more isolated than others to pop in at 11:00am each morning.

All you need to do is get your callsign in my log and I’ll call you in for a 30-second over in time.

If the net is too big, I can invite a secondary net to drop down 3kHz etc.

Phasing Harness Calulator for 71 and 84 degrees

All you need is the target frequency and velocity factor for this one. However, if using economy coax, your quoted VC may be off, so if that’s the case, you may want to measure a 90 degree test piece (that’s also shown in the calculations).

To check for accuracy, you can cut a 90 degree section of coax and short out the end. Attach to your analyser and you should get zero SWR at the target frequency. Just a tip.

The pin outs are all over the internet, so I won’t bore you with them here.

But check the video.
