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.
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.

You can buy an expensive switch box to accomplish phased array system. But to test out the theory if you’d like to go down this route, you could try a simple vertical yagi?

Tips for new Ham Radio (Amateur Radio) operators.
We have all made mistakes when we buy the wrong radio.
I give you some tips to work out how to achieve perfection. Well, certainly a balance!
I thoroughly recommend adding a dimension to your club station or special event station by live-streaming your event.
It’s not as hard as you think – and the tools are free.
Check it out.
I have since learned that some radios are more susceptible to causing this problem than others, however in my opinion, keeping your ALC to tick-over and no more will be the best policy.
Check the film.
We’re always told to check our house before accusing neighbours of local noise.
Oh heck, I wished I had listened nine-months ago!

So I had a requirement to connect my RE20 / PR40 / Shure SM58 / SM57 professional microphone to my Ham Radio (Kenwood TS2000 / TS590 / TS990s) and I show you an easy trick.
The pin outs are all over the internet, so I won’t bore you with them here.
But check the video.
What a fabulous microphone.
Check back for review and shoot-out of RE20 and PR40 soon.
Many people have got one of these. But what are they really like?
I show you.
