Ground Spike

I use an Alpha match coil screwed into a truck mirror mount and I used the small spike provided by another antenna kit the JPC-12, but the 17’ telescopic antenna is a but much in the wind so I decided to use a longer tent peg.

I took advice from Roy VK3GB who pounds a long screwdriver to first make a hole to insert the tent peg.

All this pounding is tiring and I’m not adverse to labour saving devices so I obtained from Bunnings this auger.

This was successful but with caveats.

Little green boat

Many of you will have seen the little green boat near the new 3D printer. You probably thought it was quite cute but......

It is in fact a file that tests and calibrates a 3D printer. Here is a link to an interesting article on "3DBenchy" which is the name of the boat.

As you will read there is more to 3DBenchy than just a simple boat structure.

I gave the article to my wife Jill to read and she was impressed as to just what can be done on a 3D printer. She's not a tech freak so was interesting to hear her comments.

NanoVNA

As you are aware we were generously gifted a NanoVAN analyser. This is quite an impressive piece of gear, but it does require some learning of new skills.

I belong to a FaceBook group that shares tips and ideas for this device. Here is a link, if you want to join (which I would recommend).

Thanks Phil, I have this long RG213 cable I had for around 25 years and the connections were all tarnished and I wondered if the cable is still ok. I used the VNA with the second connector to make a circuit and it will tell you how long the cable is and any losses. My cable was ok to use. So the VNA is not just a fancy SWR meter.
